摘要:

中华白海豚(Sousa chinensis)是国家一级重点保护水生野生动物, 处于食物链的顶端, 是近岸海洋生态系统健康状况的指示物种和海洋生物多样性保护的旗舰物种, 具有重要的生态、科学和文化价值。自20世纪90年代开始, 中华白海豚的研究逐渐兴起; 近年来, 随着3S技术、生态模型及分子生物学等技术方法的发展应用, 在中华白海豚种群生态学、行为生态学、分子生态学等领域的研究取得了长足发展。国内外学者利用截线抽样法和标志重捕法, 调查研究了全球范围内已知的中华白海豚种群的分布、数量等生态信息; 在物种保护的背景下, 开展了对中华白海豚栖息地的选择偏好、栖息地质量评价及潜在栖息地的预测研究; 探究了中华白海豚的觅食行为和繁殖行为的规律和其他行为的生态意义; 分子生物技术的应用, 初步揭示了中华白海豚的遗传分化规律, 以及该物种对气候变化表现出的脆弱性; 涉海工程、水下噪声、水体污染、渔业活动等人类活动仍是目前中华白海豚面临的主要威胁。本文在总结已有研究的基础上, 对未来该物种的生态学研究与保护提出了以下展望: (1)建立国家层面的动态基线数据库, 以更好地追踪中华白海豚的种群动态及栖息地环境变化; (2)构建栖息地识别及保护评价体系, 开展对中华白海豚关键栖息地和潜在栖息地的识别以及分级管理; (3)从生态系统层面开展栖息地选择机制研究, 结合生态模型探究当前栖息地对中华白海豚的承载力, 进一步探究栖息地水文要素、生物资源以及人类活动等因素对中华白海豚选择栖息地的影响; (4)构建中华白海豚遗传资源库, 探究自然选择-生态影响-遗传进化之间的联系, 以揭示物种进化、适应与濒危的分子机制; (5)为有效应对全球海洋环境变化对中华白海豚的影响, 建议在中华白海豚分布国家间建立科研合作平台及保护管理网络。

Abstract

Background & Aims: The Indo-Pacific humpback dolphin (Sousa chinensis) has been listed as the Grade 1 National Key Protected Animal in China. As the top predator of the inshore marine food chain, S. chinensis is an indicator species of the health status of the inshore ecosystem. Due to the important ecological, scientific and cultural values, it is also used as the flagship species for marine biodiversity conservation. Since the 1990s, the studies on S. chinensis have gradually risen, and developed to a new period in recent years along with the application of 3S (RS, GPS, GIS), ecological models, and molecular biological techniques. We summarized the studies of S. chinensis from the aspects of population ecology, behavioral ecology, molecular ecology and the threats that the species faced so far, aiming to clarify the advances in the ecological studies and the contributions to conservation of S. chinensis.
Progress: Ecological information such as distribution and abundance of S. chinensis population known globally in the world has been investigated by domestic and foreign scholars using line-transect sampling and capture-mark-recapture methods. In the context of species conservation, studies on habitat selection preference, habitat quality evaluation and potential habitat prediction of S. chinensis were performed. The rules of foraging behavior and reproduction behavior of S. chinensis were preliminarily understood, and the ecological significance of other behaviors were also explored. With the application of molecular biotechnology, the genetic differentiation of S. chinensis and its vulnerability to climate change have been preliminarily revealed. Human activities such as marine construction projects, underwater noise, marine pollution, and fishery activities are still the main threats to S. chinensis.
Perspectives: Based on the summary of existing studies, we propose the following prospects for the future ecological research and conservation of S. chinensis: (1) Establish a dynamic baseline database at the national level to better track the population dynamics and habitat environment changes of S. chinensis. (2) Establish a habitat identification and conservation evaluation system, and carry out identification and hierarchical management of critical and potential habitats of S. chinensis. (3) Study the habitat selection mechanism from the ecosystem level, combined with the ecological model to explore the carrying capacity of the current habitat to the S. chinensis, and further explore the impact of habitat hydrological factors, biological resources and human activities on the habitat selection of S. chinensis. (4) Construct a genetic resource database for S. chinensis, and explore the links among natural selection, ecological impact and genetic evolution, so as to reveal the molecular mechanisms of species evolution, adaptation and endangerment. (5) In order to effectively deal with the impact of global marine environmental changes on the S. chinensis, it is recommended to establish a scientific research cooperation platform and protection management network among the S. chinensis distribution countries.
