We used the literature, field investigations, specimen records and taxonomic research to categorize 515 alien invasive plant species from 72 families and 285 genera reported from China according to their biological and ecological characters, extent of spread within China, and amount of damage caused. Each species was put into one of 5 categories: malignant invasion (34 species), serious invasion (69 species), local invasion (85 species), general invasion (80 species), and species requiring further observation (247 species). According to our analyses of geographic distributional patterns, Chinese alien invasive plants were highly concentrated in the southwestern and eastern coastal provinces of China, and were rapidly spreading to inland China. These categories and distributional patterns of alien invasive plants could help to assess and control their invasive risk. Our results provide baseline information on Chinese alien invasive plants; and, at the same time, we put forward preliminary suggestions for further study, public education and the management of the important alien invasive plants in China.

Due to recent modifications of mammalian taxonomy, discoveries of mammalogy in China, and conservation needs of the country, China’s mammal diversity inventory is in urgent need of an update. We collected new species and records of mammal species in China from the literature since March 2015, adopted the new taxonomy, incorporated our own research, and added mammalian species of the Zangnan Region, to renew the inventory of mammal diversity in the country. The major changes in the new version of the inventory are the elevation of the order Cetartiodactyla to the super order Cetartiodactyla and the split of the order Cetartiodactyla in Jiang et al (2015) into orders Cetacea and Artiodactyla, respectively. Chodsigoa hoffmanni C. furva and Mesechinus sp. were added to the order Eulipotyphla. In the order Chiroptera, Murina fanjingshanensis, Myotis rufoniger and Rhinolophus subbadius were added, while Myotis hirsutus and Miniopterus fuscus were deleted from the inventory. In the order Primates, Hoolock tianxing, Trachypithecus pileatus, Nycticebus coucang and Hoolock hoolock were added to the inventory. In the order Carnivora, Melursus ursinus, Canis aureus, Vulpes bengakensis, Herpestes edwardsii, and Felis viverrinus were added. We reclassified the species in the order Artiodactyla according to the taxonomy of the Handbook of the Mammals of the World, Vol. 2, Ungulates. Ovis ammon, O. collium, Budorcas taxicolor, and Muntiacus muntjak were added to the order. All sika deer in the country were grouped as a single species, Cervus nippon, and all moose were grouped as a single species, Alces alces. Cervus alashanicus and C. macneilli as well as the dwarf blue sheep, Psuodois sharferi, were deleted, and the species of the Tragulus in Xishuangbanna was listed as Tragulus sp. In the order Cetacea, Platanista gangetica was added while Delphinus capensis was deleted. In the order Rodentia, new species, Typhlomys nanus, Neodon medogensis and N. nyalamensis, Bandicota bengalensis as well as Myospalax cansus, Biswamoyopterus biswasi, Niviventer niviventer, Mus booduga; and one species, Typhlomys daloushanensis, which was elevated from the status of subspecies, were added to the inventory, however, Hadromys humei was deleted from the inventory. The taxonomy of Arvicolini of Cricetidae was renewed. Caprolagus hispidus and Lepus nigricollis were added to the order Lagomorpha and the taxonomy of Ochotona was renewed, with 5 species downgraded from the status of species to subspecies while 4 were elevated from subspecies to species. Altogether there are 29 pika species in China. However, O. princeps, O. collaris, O. hoffinanni, O. rufescens and O. pusilla are not found in the country. The new inventory of China’s mammals has 13 orders, 56 families, 248 genera and 693 species. Compared with that reported by Jiang et al (2015), there is now an additional order, family, three genera and 20 species in the new mammalian diversity inventory. Of the mammalian species in country, the statuses of 18 species, mostly rodents, are still in dispute amongst mammalogists. There are 146 endemic mammalian species in China, which accounted for 21% of the total mammal species in the country. Of those endemic species by order, the highest endemic rate is found in Lagomorpha (37%), followed by Eulipotyphla (35%) and Artiodactyla (25%). Overall, China has the richest mammal diversity in the world.

In order to reveal composition of faunal communities in deep soil, we investigated soil at 30 and 55 cm at the Olympic Campus of the Chinese Academy of Sciences in a suburb of Beijing using trap collectors. A total of 10,163 individuals representing 20 orders belonging to ten classes and three phyla were captured in eight surveys carried out over five years. The dominant groups were Hymenoptera (61.0%), Acarina (12.1%) and Collembola (11.2%). The individuals and groups in the 30 cm soil layer were greater than at 55 cm. The dominant group of the 30 cm soil layer was Hymenoptera (69.4%) while at 55 cm, Hymenoptera (45.7%), Acarina (21.8%) and Collembola (16.4%) were all dominant. The number of individuals and groups recorded from April to October was greater than October to April of the next year. Annelida appeared only between October to April of the next year, while Thysanoptera, Psocoptera, Dermaptera appeared only between April to October. The lowest Jaccard value of soil faunal communities in different vegetation forms was 0.75. None of Shannon-Wiener diversity index, Simpson dominance index and Pielou evenness index showed significant differences between different vegetation types (P > 0.05). The results showed that there were abundant soil faunal communities in deep soil. The number of individuals and groups decreased with increasing soil depth. Soil faunal community structure was different in different seasons and the composition was highly similar between different vegetation types.

Angiosperms constitute the most diverse lineage of higher plants and are represented by ca. 300,000 living species that dominate the vegetation of terrestrial ecosystems. Number and composition of families, genera, and species are important to understanding global and regional biodiversity. Due to the rapid development of molecular systematics, circumscriptions of many traditional angiosperm families and genera have been revised. This study investigates circumscriptions of families and genera of native and introduced angiosperms in China according to the APG III classification system and recent phylogenetic studies. Results showed that there are 258 native and 55 introduced families (including 6 naturalized families), and 2,872 native and 1,605 introduced genera (including 152 naturalized genera) in China. A brief introduction to the historical and recent changes of circumscriptions of families and genera occurring in China was also provided. Our list included 115 newly recorded families and 1,729 newly recorded genera when compared to Flora Reipublicae Popularis Sinicae, and 85 newly recorded families and 1,531newly recorded genera when compared to Flora of China.

World Natural Heritage site is recognized globally as the pinnacle of natural protected areas that are the cornerstones of biodiversity conservation. The World Natural Heritage of Shennongjia represents one of the worldwide biodiversity hotspots. But, until now, it has not been clear how outstanding the universal value of Shennongjia is worldwide, and this study presents one of the most compelling challenges to conservation efforts. Here, we compiled literature and conducted additional field surveys in the Shennongjia region to illustrate the outstanding universal value of Shennongjia World Natural Heritage Site using World Heritage criteria (ix) and (x), following the operational guidelines for the implementation of the World Heritage Convention. Results show that the heritage of Shennongjia offers an outstanding example of the ongoing ecological processes occurring in the development of intact subtropical mixed broad-leaved evergreen and deciduous forests in the Northern Hemisphere. This region presents a typical example of mountain altitudinal biological zones in the Oriental Deciduous Forest Biogeographical Province. Shennongjia is also a vital origin location for global temperate flora, and harbors the highest concentration of global temperate genera of trees. Moreover, the heritage of Shennongjia displays exceptional biodiversity and is a key habitat for numerous relic, rare, endangered and endemic species. The richness of deciduous woody species in Shennongjia is the highest in the world. Our study provides great insight into protecting, monitoring and managing the outstanding world heritage in the Northern Hemisphere.

Soil microbial diversity has not been extensively observed due to technique limitations. With the development of the high-throughput sequencing technique and bioinformatics, much progress has been made in observations of microbial diversity. Currently, international microbiome initiatives have been founded (including the Earth Microbial Project). However, problems in these projects include a lack of dynamic observations, differences in observational methods, and data integration. The soil microbial observation network (SMON) is an important part of the Chinese Biodiversity Monitoring and Research Network (Sino BON). The observational network initially selected field observation sites in forest ecosystems along a temperature and precipitation gradient from south to north, in grassland ecosystems along a precipitation transect from east to west, and in typical wetland and agricultural ecosystems in China. Field ecological observation stations have been established in these selected ecosystems. Key tasks for the SMON are to observe spatial and temporal dynamics of soil microbial communities and functional genes in various ecosystems, including bacteria, archaea, fungi, and lichens. Observational data will be published periodically in the format of database, annals, and illustrated handbooks. Key methods used in the SMON are high- throughput sequencing, metagenomics, and bioinformatics. A soil biota database is currently being constructed to store observational data for public inquiry and analysis. Through the efforts of SMON, we plan to explore the driving mechanisms of spatial and temporal variations of soil microbial communities and their functional genes, and understand the relationships between microbial diversity and ecosystem function, in order to predict microbial dynamics under global environmental change scenarios, and to design strategies to protect soil microbial diversity and properly utilize microbial resources.

This paper summarizes the research status, existing issues, and trends in floristic geography. There is now a wealth of research accumulation on floristic investigations, distribution types of genera, floristic regions, and regional floristic analysis. It is also noted that most of these studies utilize simple statistical analyses, comparative studies, traditional methods, and single subjects, to provide a basic understanding and description of the floristic phenomenon, which is lacking spatial pattern formation processes and detailed exploration of formation mechanisms. Additionally, there are still some weak and non-existent areas of botanical investigation. Many existing specimens lack detailed or accurate information and the precise identification of plant species also needs to be much improved. At the same time, when analyzing the development trends of floristic geography, with the rapid development of related disciplines, including the development of biogeography and analysis methods and improvements, floristic geography research is an area of multidisciplinary integration, comprehensive research, and analysis. On the one hand, using database information, and combining ecology, paleobotany, and geology can allow us to probe into spatial pattern formation. On the other hand, combining phylogenetics, the tree of life, and molecular biogeography allow us to reveal floristic origins and evolution. The rapid development of various disciplines has given rise to a large amount of data, meanwhile, the emergence and application of new analytical methods and theories incorporate big data into floristic geography research, which will enhance qualitative understanding and description, and allow us to further explore the mechanisms of formation quantitatively.

In order to provide a scientific basis for upgrading the level of a nature reserve (NR) and selecting the appropriate management type, the conservation priority of NRs should be identified. How to objectively identify conservation priorities has become a key problem. We propose a mathematical method to comprehensively assess species diversity conservation values by comparing existing evaluation indexes and methods, consulting experts and processing indexes quantitatively. This evaluation method includes the following indices: the wild plant diversity conservation value index; wild animal diversity conservation value index; rare and endangered wild plant diversity conservation value index; and the rare and endangered wild animal diversity conservation value index of a NR. Meanwhile, 39 NRs in North China Warm Temperate Region and 67 NRs in Northeast China Temperate Region were selected as case studies to verify methods, based on species diversity data of the NRs. The evaluation results revealed that some provincial NRs could be recommended for an upgrade to national NRs, due to high species diversity conservation values, including the Nandagang Wetland and Liaohe River Source NRs of Hebei, Wuling Mountain NR of Beijing in the North China Warm Temperate Region, the Jingpo Lake, Dajia River, and Cuibei Wetland NRs of Heilongjiang in the Northeast China Temperate Region. The computation method showed a great advantage in comparing species (various groups) diversity conservation values for different NRs and determining the conservation priority sequence. Moreover, there were significant differences in the species diversity conservation value of NR among different natural conservation geographical areas, and types of NRs.

Jiaozhou Bay is a semi-enclosed bay at the southern shore of Shandong Peninsula and has abundant macrobenthic species. In present study, the seasonal variation of the macrobenthic community in this bay was analyzed based on data collected from four cruises in February (winter), May (spring), August (summer) and November (autumn) of 2014. A total of 199 macrobenthic species were identified, of which, 79 species were Polychaeta, 47 were Crustacea, 40 were Mollusca, 17 were Echinodermata, and the remaining 16 species belong to other animal groups. The composition of dominant species seasonally varied, however, most of them were species belong to Polychaeta. The average abundance of the macrobenthos from the four cruises was 209.85 ind./m2, with the highest abundance found in the autumn cruise and the lowest in the spring cruise. The average biomass from the four cruises was 79.22 g/m2, with the highest biomass found during the summer cruise and the lowest found during the spring cruise. The Shannon-Wiener index (H') of the macrobenthic community varied from 2.16 to 2.86, the species richness index (D) varied from 2.79 to 3.72 and the species evenness index (J) varied from 0.58 to 0.82. The Bray-Curtis similarity cluster analysis and NMDS ordination analyses indicated that the similarity among macrobenthic community groups was low and the distribution pattern of microbenthic animal groups showed seasonal characteristics. In recent years, with the rapid economic development of coastal zones and the continuous impact of human activities, the stability of the benthonic community in Jiaozhou Bay is threatened, therefore, long-term monitoring is recommended and effective comprehensive management measures need to be explored to result in the healthy and sustainable development of the marine ecosystem in Jiaozhou Bay.

China’s mammalian fauna is unique: it possesses the endemic species and genera of the Qinghai-Tibetan Plateau; it has the relic families, Ailuropodidae and Lipotidae, of the Tertiary Period; more than half of the species of the Ochotonidae in the country are endemic; furthermore China is also the country with world most abundant ungulate diversity. In the new millennia, changes to the taxonomy of mammals of world were proposed. New mammalian species and new mammals were reported in China. Thus it is necessary to renew the inventory of China’s mammal diversity. During the compiling of The Red List of Endangered Species in China: Mammals, we collected the available data on China’s mammals (including those of Taiwan) and formed The Checklist of China’s Mammal Species 2015. For taxonomy of orders, we followed the existing theory using molecular phylogeny whereas for the classification of families and the taxa below family level, we followed the A Complete Checklist of Mammal Species and Subspecies in China: A Taxonomic and Geographic Reference by Wang (2003) and Mammal Species of the World: A Taxonomic and Geographic Reference by Wilson & Reeder (2005). We also adopted Ungulate Taxonomy by Groves & Grubb (2011) to classify the ungulates in China. The initial list included species recorded in taxonomic books and field guides, new species and new records in literature before March 31, 2015. After five evaluation meetings and two rounds of evaluation by correspondence, we finalized The Checklist of China’s Mammal Species 2015, which includes 12 orders, 55 families, 245 genera and 673 species. Among those species, 18 new species (including 11 discovered with molecular biology methods, the validity of the species are still in dispute among zoologists), 18 new species records in country, and 60 subspecies were elevated to the status of species were added to the checklist. According to literature and expertise, we deleted 52 species which are not found in China. Of them, specimens of some species were collected only once, and then never been found again during following surveys. Taxonomists hold different opinions on 20 Glires, and those species need further investigation. Compared with the data of IUCN Red List (2014), the number of mammal species in China recorded in the study is surpassed that of Indonisia (670), China became the country with the most abundant mammal species in the world. The mammals in China accounted for 12.3% of the world total numbers of mammalian species. There are 150 endemic mammals in China, which accounted for 22.3% of the national total. 43% of the species in Lagomorpha are endemics to the country. The endemic ratio of Ochotonidae is even higher, 52% of the total. Endemic ratio of Eulipotyphla is 35%. About one fifth of Primates, Chiroptera and Rodentia in China are also endemics, including 12 new bat species discovered in the country during recent decade. The Checklist of China’s Mammal Species 2015 provides the most updated baseline information for biodiversity research and conservation.

The abundance and seasonal variation of phytoplankton were studied in the eastern marginal China seas (25.00°–39.00° N, 118.00°–129.00° E). Based on surveys in June and July 2006, January and February 2007, November 2007 and April and May 2009, we analyzed the species composition, community structure, and cell density of netz-phytoplankton (mesh size 77 μm). A total of 257 phytoplankton species were identified, belonging to 70 genera and 4 classes. Bacillariolhyta was the dominant functional group, followed by Pyrrophyta. The dominant species were Skeletonema spp., Thalassiosira subtilis, T. scrotiformis, Thalassionema frauenfeldii, T. nitzschioides, Paralia sulcata, Chaetoceros lorenzianus, C. curvisetus, Pseudo-nitzschia pungens and Noctiluca scintillans. The cell density of the phytoplankton ranged from 0.02×104 cells/m3 in the Yellow Sea in winter to 31,350.21×104 cells/m3 in the Yangtze River in spring. Overall phytoplankton cell density showed the following seasonal trend: spring > summer > autumn > winter.

How species coexist locally is a fundamental question in community ecology. Classical coexistence theory underscores the importance of niche differentiation between species and focuses on specific coexistence mechanisms. Studies on these specific coexistence mechanisms have profoundly contributed to understanding species coexistence at the local scale and inspired ecologists to create a more general contemporary coexistence theory. Under the contemporary coexistence theory, species differences are categorized into two groups: niche differences and average fitness differences. Niche differences serve as stabilizing mechanisms that promote species coexistence, whereas average fitness differences are related to equalizing mechanisms that drive competitive exclusion. In this paper we provide a detailed review of contemporary coexistence theory, including its definition and theoretical models, empirical tests of these models and their applications to biodiversity studies. Coexistence theory has applications in a number of other areas including biodiversity conservation and management in a changing world beyond the basic concept of how communities are structured. We show how contemporary coexistence theory has advanced the niche-based classic coexistence theory, helping us to better understand the underlying mechanisms of community assembly and biodiversity maintenance.

Beta-diversity partitioning: methods, applications and perspectives
Xingfeng Si, Yuhao Zhao, Chuanwu Chen, Peng Ren, Di Zeng, Lingbing Wu, Ping Ding

Beta diversity describes the variation in species composition among communities within a region and it is determined by two antithetic processes: species turnover (or species replacement), and nestedness (or difference in richness). Beta-diversity partitioning aims to separate these two processes when examining species composition among communities, and to reveal their underlying mechanisms. Since 2010, the partitioning methods were proposed following two dominant frameworks: the BAS method proposed by Andrés Baselga in 2010 (partitioning overall beta diversity into turnover and nestedness components) and the POD method proposed by János Podani and Dénes Schmera in 2011 and José C. Carvalho et al. in 2012 (partitioning overall beta diversity into species replacement and richness difference components). With the continuous debate on the nature of the BAS and POD methods, studies on beta-diversity partitioning have developed rapidly worldwide. We reviewed journal articles in the field of beta-diversity partitioning since 2010. Results showed that the number of publications and citations using the BAS method were greater than those using the POD method (75% vs. 20%). In those publications, most of study sites were located in Europe (45%) and research taxa were dominated by animals (64%). Here, we introduce the history and development of beta-diversity partitioning, potential applications in studying biodiversity distributions across spatial-temporal scales (latitudinal/altitudinal gradients, habitat fragmentation, seasonal and annual dynamics), multiple-faceted diversity (taxonomic, functional and phylogenetic diversity), and comparisons among various biological taxa. We point out the following directions in the field of beta-diversity partitioning in the future: (1) the synthesis and comparative analysis of the methods of beta-diversity partitioning; (2) examining patterns of overall beta diversity and its components by incorporating species abundance; and (3) testing the generality of results yielded from beta-diversity partitioning across large scales.

Sprouting, a life history strategy found in woody plant communities, enables woody plants to persist in situ through disturbance events. The ‘persistence niche’ of sprouting has important influences on species coexistence, community assembly, and ecosystem stability. However, the mechanism of the ‘persistence niche’ in maintaining species diversity is not well understood. Based on data collected in a 5 ha plot in a mid-subtropical evergreen broad-leaved forest in the Gutianshan National Natural Reserve of Zhejiang Province, China, we analyzed the characteristics of sprouting and their relationships with species diversity. Our results revealed that the sprouting species had a great proportion of 63.95% in richness and a high proportion of 38.53% in abundance, especially a higher abundance proportion of 59.51% of potential sprouting at the community level. Sprouting occurred in most taxa, and there was high ability of sprouting in Fagaceae, Ericaceae, Hamamelidaceae, and Theaceae. There were significant negative correlations between abundance proportion of sprouting species and the biodiversity index of the community, despite no relationships between richness proportion of sprouting species and biodiversity index. Therefore, the sprouters could retain their position in forests and reduce biodiversity of the forest community. This trade-off of sprouting may result in the maintenance of community stability.

Ecosystem services and the natural capital stocks that produce them are critical to the functioning of the Earth′s life supporting system. They contribute to human welfare, both directly and indirectly, and therefore represent part of the total economic value of the planet. Four scientific quastions about the functions of ecosystem services are discussed in this paper. They are: 1) study of the integration, amount and spatial location of functions of ecosystem services; 2) the spatial transfer of functions of ecosystem services; 3) the relationship between ecosystem service and ecological security; and 4) the sustainable use of ecosystem services. The heterogeneity in the structure of ecosystem's results in heterogeneity of their functions. Consequentially, there is spatial heterogeneity in the functions of ecosystem services. Thus, it is necessary to analyze the functions of ecosystem services by qualitative, quantitative and spatial means. Some functions of ecosystem services can be transferred spatially by various methods, and produce benefits at areas far removed from their habitats and range of suitable conditions. This phenomenon is called spatial transfer of ecosystem services. Thus, characteristic ecosystem services can bring economic values to a region of larger area than that covered by the ecosystem′s habitats. Ecosystem services provide supporting system for humans, and their strengths depend on ecological capital stock. Ecological capital stock illustrates the capability of sustainable development of a country. Ecological capital stock of an ecosystem relies in turn on the function and the structure of the ecosystem. Endangerment of ecosystem service raises a question for ecological security. In many regions ecological resources are rare. To use ecological resources sustainably, local communities should be urged to develop their economies by means of managing ecosystem services, i.e., to industrialize the management of ecosystem services. These four scientific questions for ecosystem services are related to each other. The aim of discussing them is to focus study on ecosystem services in the future.

One of the diverse species concepts defined before may only perceive one aspect of the mature species like “the blind men feel the elephant” while the mature species at the final speciation stage should have integrated all species concepts. Most “species” in the nature are on the way to the final speciation stage. However, before reaching the final speciation stage, these species undertake further cycles of speciation. Species from the repeated splits of the incomplete divergences show incomplete reproductive isolations, frequent interspecific gene flow and reticulate evolutions. In addition, the earliest divergent gene differs between different pairs of species. Therefore, the divergence orders for different species concepts vary greatly between organisms. Such random divergences lead to the extreme difficulty to define a common and accurate species concept for all “species” on the speciation way. It is better to delimitate species, publish new species and conduct taxonomic revisions based on conditions and approaches of as many species concepts as possible. In addition, incomplete reproductive isolations, limited interspecific gene flow and some ‘abnormal’ individuals not ascribed to any species due to interspecific hybridizations and within-population mutations should be widely acknowledged during species delimitations. Such circumscribed species may be more objective and scientific than previously delimitated based only on one single species concept.

Ecological protection redline (EPR) is a new concept recently put forward in the Environmental Protection Law of the People's Republic of China and the Third Plenary Session of the 18th Central Committee of the Communist Party of China. Policy regarding the implementation of protection is strictest in EPR areas. Although there was no EPR worldwide previously, most countries had established protected areas, a similar practice to EPR, in natural or near natural areas, aiming at protecting species, habitats and ecosystems. In this paper, we summarize the ecological protection systems and their management practice executed by IUCN and in other foreign countries (USA, EU, Russia, Japan, etc.) based on relevant literature. Ecological protection areas range from 5% to 40% for most countries. In these countries, a specific management system is either governed by a special protection management department or a multi-sectoral management division. Different management and control measures are decided according to the human activity intensities. Based on gap analysis research in China’s presently protected areas and problems in classification management of protected areas, we suggest integrating and optimizing different types of protected areas by evalua- ting their importance and sensitivity. Land with important ecological service, biodiversity and habitat protection functions should be preferentially included in EPR. The area ratio assigned to EPR should be up to 30% of the total land area. We propose that unified supervision and management by China’s environmental protection departments should be strengthened, establishing EPR management laws and regulations, and implementing different management measures according to its classifications.

Rhinogobio ventralis, an endemic species in the upper Yangtze River, has been threatened by overfishing and dam construction. To understand its population dynamics after the Three Gorges Reservoir was built and before the Xiangjiaba and Xiluodu reservoirs were built, we employed body length-frequency data to estimate growth and mortality parameters, population abundance and utilization of the fish based on surveys in the Jiangjin and Yibin sections of the upper Yangtze River conducted from 2007-2009. Fish ranged from 52 to 250 mm in length and 2.7 to 307.2 g in weight, with an average length of 150.8 ± 40.7 mm and an average weight of 72.3 ± 49.7 g. The average size of the fish in the Jiangjin section of the Yangtze River (168.6 ± 29.5 mm) was significantly larger than that in Yibin section (125.6 ± 41.2 mm). The length-weight relationship of R. ventralis was well-fit with a power function, W = 6.06 × 10-6 L3.20 (R2 = 0.98, P < 0.01, n = 436). Asymptotic length (L) and growth constant (k) were estimated using length frequency data as 338 mm and 0.24/yr, respectively. Average natural mortality was comprehensively estimated as 0.43 using three empirical formulas proposed by Pauly, Gunderson & Dygert, and Jensen, respectively. The total mortalities were estimated using a length-converted catch curve analysis as 2.26 in the Jiangjin section and 2.09 in the Yibin section of the Yangtze River. The observed exploitation rates were 0.81 in the Jiangjin section and 0.79 in the Yibin section, which were higher than the maximum exploitation rates of 0.57 in the Jiangjin section and 0.62 in the Yibin section that were estimated using Beverton & Holt Y′/R analysis. Population abundance of R. ventralis in the Jiangjin section was estimated by length-structured virtual population analysis as 68,247 in 2007, 67,432 in 2008, and 176,266 in 2009, respectively, with an average of 103,982; while abundance in the Yibin section was estimated as 22,953 in 2007, 46,340 in 2008, and 34,021 in 2009, respectively, with an average of 34,438, indicating the population abundance was higher in the Jiangjin section than the Yibin section. We conclude that overfishing is occurring in these stocks of R. ventralis and recommend a longer period of monitoring in order to understand population dynamics of R. ventralis. We further suggest that management authorities establish a longer closed period for fishing and undertake habitat restoration to protect the endemic fish species.

In this review, based on recent studies of population genetics and phylogeographics of East Asia’s Tertiary relict plants, we have outlined the main phylogeographic patterns and processes. We also summarize common geographic and environmental factors which may contribute to the phylogeographic patterns of East Asia’s Tertiary relict plants and present future challenges and research prospects. There are four recurrent phylogeographic scenarios identified by different case studies, including: (1) the global cooling and aridification during the Middle and Late Miocene induced recent speciation, with climate change during the Late Pliocene and Pleistocene accounting for their intra-specific lineage divergence, genetic diversification and demographic expansion/contraction. The latitudinal contraction/expansion can lead to the formation of “suture zone” for some relict plants; (2) the effects of the formation of the glacial East China Sea land bridge, as a “corridor” or “filter”, have to account not only for habitat preferences per se but also for other biological features of different relict plant species; (3) the uplift of the Qinghai-Tibet Plateau (QTP) during the Late Pliocene and the intensification of East Asian monsoon system (EAMS) are the most suggestive factors responsible for the major phylogeographic break between the western and eastern lineages across the Sichuan Basin and northwestern arid regions; and (4) some Tertiary relict plants migrated southward to Taiwan from mainland China or Japan before the Pleistocene under global climatic cooling and aridification since the Late Miocene, and refugial isolation that occurred between Taiwan and mainland Asia accelerated vicariant lineage diversification and speciation. Overall, both historical and contemporary geography and environment have affected the distribution, genetic diversity, lineage divergence and speciation of East Asia’s Tertiary relict plants. Finally, we emphasize notable gaps in our knowledge due to the long-term application of simple molecular clock based on very limited genetic markers, and outline future research prospects for disentangling the evolution and biogeographic history of East Asia’s Tertiary relict flora. We present the utilization of genome data and biogeography models and integrative phylogeographic research of multi-taxon communities as possible future directions.

During the past decade, unmanned aerial vehicle (UAV) based remote sensing has been increasingly used in the fields of vegetation inventory, natural resource management, and biodiversity conservation, due to its low cost and high flexibility. In this study, we present a reference for the selection of UAV platforms and remote sensing sensors, by introducing a UAV classification system and summarizing applicability in biodiversity monitoring using remote sensing techniques. For each UAV platform category, we also introduce the characteristics and capabilities of different remote sensing sensors that can be supported. Moreover, through the combination of a case study which collected high-fidelity UAV-based remotely sensed data, we discuss current research progress using UAV-borne remote sensing data to derive direct and indirect biodiversity parameters. Finally, we discuss the current limitations of UAV-based remote sensing platforms for biodiversity monitoring, such as the existing gap between hardware and software, the high cost of certain components (e.g. the initial measurement unit), incomplete laws and regulations, and the disconnect with traditional biodiversity monitoring methods. In summary, we believe that UAV-based remote sensing platforms can greatly help to fill the gaps between terrestrial measurements and aerial/spaceborne measurements, and can increase the accuracy and reliability of upscaling point-based terrestrial measurements to the regional scale. There is a need to launch more projects that address building a UAV-based biodiversity monitoring network, and therefore improve our capability to analyze and forecast biodiversity changes in hotspots.

Ten strains of crude oil degrading bacteria were isolated from three soil samples. The isolates were Gram-negative, aerobic, non-spore-forming rods. All of the ten isolates were able to grow on nalkanes with medium length, diesel fuel and crude oil, but not polycyclic aromatic hydrocarbon. Based on phenotypic characteristics and 16S rDNA sequence analysis, ten isolates were identified as Pseudomona spp. (strain EVA5,EVA6,EVA7,EVA8,EVA9) and Acinetobacter spp. (strain EVA10, EVA11,EVA12,EVA13, EVA14), respectively.

Sampling strategy is very important for core collection establishment. In this study, different methods to construct a core collection of Changjiang spring sowing soybean were performed based on data of SSR(simple sequence repeat) markers and agronomic traits in order to optimize the sampling strategy for core collection. The results showed that, based on cluster analysis of SSR data, each of the three methods, i.e., random sampling within each group, sampling by genetic similarity coefficient within each group and sampling by genetic similarity coefficient, could be used to construct a soybean core collection. When SSR allelic reserving ratios were maintained at 90% and 80%, the core collections had higher genetic diversity indices of SSR alleles than if maintained at 70%. Core collections could also be constructed by agronomic and other basic data if there was no molecular data; however, SSR allelic reserving ratio might be decreased, which suggested that assessment of genetic diversity by SSR data was not always consistent with assessment by agronomic data. We found that core collections were heterogeneous, either when created with different sampling methods or with the same sampling method in different repeats, because randomicity always existed in selecting individuals. This indicated that the germplasm to form a core collection was variable, so optimal sampling strategies should be chosen to establish core collections based on different data according to practical or scientific objectives. Integrating phenotypic and genotypic data together would be better for improving the representativeness of core collections.

Otters are rare and threatened in China, but both research and conservation efforts on this specialized group of mammals are largely overlooked. To provide baseline information on the current conservation status of otters in coastal Guangdong Province, we conducted rapid otter surveys using semi-structured interviews, transects, camera-trapping surveys, and a molecular study of the coastal islands of Zhuhai City between September 2016 and March 2017. Data collected suggested a dramatic decline of otter populations and the local extirpation of otters was reported on several islands. The discovery of a remnant population of the Eurasian otter (Lutra lutra) on Hengqin Island provides hopes for the recovery of this species in South China. Nonetheless, the future of Hengqin’s otter is at stake due to the rapid urbanization of suitable habitats for economic development. To ensure its continual survival, critical habitats on Hengqin Island should be strictly protected as soon as possible. Furthermore, systematic, otter-specific surveys should be conducted in other coastal areas of China, to best devise a national otter conservation plan.

Alien invasive species have become a serious environmental issue throughout the world. It is necessary to launch a nationwide investigation on alien invasive species, so as to obtain baseline data, identify causes of invasion, and put forward effective control strategies and measures. Data on classification, origin, pathway and environmental impacts of alien invasive micro-organisms, invertebrates, amphibians and reptiles, fish, birds, mammals, weeds, trees in terrestrial and aquatic ecosystems and alien invasive species in marine ecosystems of China were analyzed, based on literature research, field survey and consultation. 283 alien invasive species have been identified in China, and the number of species of alien invasive micro-organisms, aquatic plants, terrestrial plants, aquatic invertebrates, terrestrial invertebrates, amphibians and reptiles, fish, and mammals were 19, 18, 170, 25, 33, 3, 10, and 5, respectively. The proportion of alien invasive species originating from America, Europe, Asia, Africa and Oceania were 55.1%, 21.7%, 9.9%, 8.1% and 0.6%, respectively. Many institutions and individuals in China lack adequate knowledge of ecological and environmental consequences caused by alien invasive species, with some blindness in the introduction of alien species. For instance, 50.0% of alien invasive plants were intentionally introduced as pasture, feed stock, ornamental plants, textile plants, medicinal plants, vegetables, or lawn plants. 25% of alien invasive animals were intentionally introduced for cultivation, recreation, or biological control. In addition, much effort has been made on introduction of alien species, and little attention has been paid to the management of introduced alien species, which may allow their escape into natural environments and potential threats to the environment. There are also gaps in the quarantine system in China. All invasive micro-organisms were unintentionally introduced, through timber, seedlings, flowerpots, or soil. 76.3% of alien invasive animals invaded through commodity or transportation facilities because of the failure of quarantine. It is recommended that quarantine measures should be strictly implemented. At the same time, the intentional introduction of alien species should be strictly managed and a system of risk assessment should be implemented.

There is a dynamic interplay between ecology and evolution within community ecology. Phylogenetic community ecology describes the intraspecific and interspecific relationships within a community, aiming to reveal the processes driving community assembly at multiple scales. Previous research has highlighted the role of phylogenetic and historical biogeographical data in explaining current patterns of global biodiversity. The success of using DNA barcoding in the construction of tropical forest community phylogenies highlights the usefulness and challenges of long-term research on community ecology and phylogenetics based on forest dynamic plots. In this paper, we illustrate the feasibility of a synthesis between community ecology and evolutionary biology in order to resolve particular ecological issues on community phylogenetic structure, community niche structure, biogeography, and trait evolution. We summarize progress on the development of a plant DNA barcoding system, and introduce the usage of a combination of DNA markers (rbcL+matK+trnH-psbA) for fast species discrimination and community phylogenetic reconstruction. We also explore the utilization of well-resolved phylogenies to understand community ecology. We discuss the limitations of core plant DNA barcodes (rbcL+matK) when identifying congeners, and propose an improved sequencing strategy suitable for studies at the community level. We expect that plant DNA barcodes will prove very useful for the study of species diversity, mechanisms of biodiversity maintenance, phylogenetic beta diversity and functional trait evolution.

The aims of our study were to (1) uncover new reef fish species records using the underwater visual census method; and (2) analyze the fish community structure according to trophic groups and its response to water quality changes. The fishes on six reefs (Yongxing Island, Dongdao Island, Lingyang Atoll, Jinyin Island, Huaguang Atoll, and Zhongjian Island) along the Xisha Archipelago were investigated in May-June, 2006 using underwater visual censuses. The fishes we recorded belong to 29 families, 71 genera and 119 species. The number of newly recorded species was 50. The number of fish species increased to 717 in the Xisha area since the 1950’s. The species number and Shannon-Wiener diversity were both highest on the western reef of Yongxing Island. Most fish species were distributed narrowly in small areas. The dominant assemblages were the planktivores and bottom invertebrate feeders. The rare assemblages were the herbivores, the omnivores, and the top predator, the piscivores. The structure of trophic groups indicated that most coral reef systems were relatively healthy. The percentage of total abundance (and biomass) comprised by omnivores was largest on the western reef of Yongxing Island compared to other reefs, suggesting that the fish community structure had responded to water eutrophication around Yongxing Island.

Studying the dynamic characteristics, species coexistence and biodiversity conservation mechanisms of subtropical forest ecosystems is important in the study of the quantitative characteristics and spatial gap distribution patterns. Based on census data from the 20 ha dynamics plot of the subtropical evergreen broad-leaved forest in Dinghushan in 2015, we analyzed the geometric characteristics and spatial distribution pattern of gaps in the plot by combining aerial image processing technology of unmanned aerial vehicles and GIS. Results show that the gap fraction is 13.72%, the gap density is 35.75 no./ha, and the average gap area is 38.37 m2. Results also show that: (1) The number of gaps in the area is negatively exponentially distributed with the increase of gap area, that is, the gap is small and the marginal effect is not significant. (2) The average area of ??forest gaps in over-mature forest stands is larger than that in mature forests, while the mature forest is more likely to have more small gaps and fewer large gaps. (3) In different habitats, the distribution of gaps in each habitat shows the same pattern as that found in the whole plot. However, the difference in the valley is significant when compared with other habitats, and gap area and gap density in the valley are larger than other habitats. The ridge gap is also distinctive, and its gap density is lower than other habitats. (4) Gap area is significantly correlated with topographic factors. It was significantly negatively correlated with altitude and convexity, and had a significantly positive correlation with aspect and gradient. Based on these comparative analyses, a monitoring system of forest canopy changes and patterns can be established using drones, to dynamically monitor forest gaps and the undergrowth community.

On the niche stasis of intercontinental invasive plants

Biological invasions represent a growing threat to biodiversity. The movement of organisms among continents by humans has caused profound changes in structure and function of the ecosystem to which they have been introduced. By testing the differences in the relative contributions of the various origins of the invasive plants to each region, we found intercontinental invasions were more prevalent than intracontinental invasions, primarily including the exchange of species among Eastern Asia–North America, Eastern Asia–South America, Europe–South Africa, Europe–North America, Europe–Eastern Asia, and North America–Oceania. They have posed a higher threat than intracontinental invasions. Thus, preventing future invasions is the most cost-effective form of management. Species distribution models (SDMs) are increasingly used to estimate risks of biological invasions. Niche stasis, the tendency of a species niche to remain unchanged across space and time, is often assumed when applying these models to predict and explain biogeographical patterns. Yet, both niche change and conservatism have occurred for intercontinental invasive exotic plants, which were severely disconnected from their source populations and often adapt rapidly to conditions in the new range. To further understand the niche characteristics of invasive species, it is therefore necessary to consider which factors limit range expansion in the native region. After comparing the similarities and differences of invasive species expansion across continents to within continents, we propose that the probabilities of niche shifts occurring depended primarily on the ecological and evolutionary processes limiting the species in its native range such as dispersal limit, species interaction, adapted evolution, ecological plasticity and population characteristics. Most limited factors of species niche properties are more consistent with there being a niche shift than niche stasis in the new range. Therefore, we suggest the following areas for future research: (1) multi-scales studies on niche attributes across spatial, temporal, environmental and phylogenetic investigations; (2) comparative studies that identify both the groups of species that are characterized by environmental niche stasis or shifts, and the traits that the species are more prone to niche change; and (3) niche dynamics over time to estimate the propensity, historical rate, and magnitude of niche shift. Such understanding will improve our confidence in SDM-based predictions of the impacts of climate change and species invasions on species distributions and biodiversity.

Angiosperm phylogenetics investigates the evolutionary history and relationships of angiosperms based on the construction of phylogenetic trees. Since the 1990s, nucleotide or amino acid sequences have been widely used for this and angiosperm phylogenetic analysis has advanced from using single or a combination of a few organellar genes to whole plastid genome sequences, resulting in the widely accepted modern molecular systematics of angiosperms. The current framework of the angiosperm phylogeny includes highly supported basal angiosperm relationships, five major clades (eudicots, monocots, magnoliids, Chloranthales, and Ceratophyllales), orders grouped within these clades, and core groups in the monocots or eudicots. However, organellar genes have some limitations; these involve uniparental inheritance in most instances and a relatively low percentage of phylogenetic informative sites. Thus, they are unable to resolve some relationships even when whole plastid genome sequences are used. Therefore, the utility of biparentally inherited nuclear genes with more information about evolutionary history, has gradually received more attention. Nevertheless, there are still some plant groups that are difficult to place in the angiosperm phylogeny, such as those involving the relative positions of the five major groups as well as those of several orders of eudicots. In this review, we discuss the applications, advantages and disadvantages of marker genes, the deep relationships that have been resolved in angiosperm phylogeny, groups with uncertain positions, and the challenges that remain in resolving an accurate phylogeny for angiosperms.

As the most direct and active ecological interface of the interaction between forest and its environment, the forest canopy, known as the earth’s “eighth continent”, contains the greatest forest biological diversity, and plays an important role in the formation and maintenance of biodiversity as well as the processes and functions of the ecosystem. However, the forest canopy is highly sensitive to global climate change and human disturbance. In the wake of increasing human activities and global climate change, the forest ecosystem, especially the forest canopy, is facing a serious threat. Therefore, protection of forest canopy biodiversity and sustainable utilization are increasingly important issues in modern ecology research under the scenarios of climate change, and have gained more and more attention in the fields of forest ecology, climatology, and environmental science. Accordingly, in 2015, the Chinese Forest Canopy Biodiversity Monitoring Network was created within the framework of Sino BON. This network includes biodiversity monitoring plots those were or will be equipped with forest canopy cranes. According to international standards, the network will unify monitoring parameters of forest canopy biodiversity using monitoring standards and norms, and conduct long-term monitoring of plant diversity (including epiphytic seed plants and epispore plants), fauna diversity, microbial diversity and their dynamic changes, through large scale zonal forest canopies. Combined with monitoring of the microclimate, we will build four dynamic databases (including a forest canopy microclimate database, canopy plant, canopy arthropod, and canopy microbial). The network is expected to discern the change patterns of forest canopy biodiversity of typical forest ecosystems in China, and to reveal how they influence the functioning of forest ecosystems and respond to global change.

Based on the IUCN Red List Categories and Criteria (Version 3.1), we assessed native gymnosperm species and infraspecific taxa found in China between March of 2010 and December of 2012. Results indicated that 37 species were critically endangered (CR), 35 species were endangered (EN), 76 species were vulnerable (VU), 87 species were of least concern (LC), and 16 species were data deficient (DD). Up to 59% of the 251 native species of gymnosperms found in China were classified as threatened. Threatening factors impacting gymnosperm species in China were ascribed into seven categories, among which habitat degradation, restricted distribution, and over exploitation were listed as the top three threats. According to results of red list assessments and conservation practices of gymnosperms in China, we propose that conservation of endangered gymnosperm species should have a targeted program. Otherwise, over-protection could result in additional threats to endangered species.
