Multi-dimensional evaluation of small mammal diversity in tree line habitats across the Three Parallel Rivers of Yunnan Protected Areas: Implications for conservation

doi:10.17520/biods.2021006

Abstract

Abstract:

Aim: To evaluate multi-dimensional biodiversity levels of small mammals in tree line habitats across the Three Parallel Rivers of Yunnan Protected Areas (TPR), and discuss their implication for conservational strategies.
Methods: Between September 2013 and November 2018, we conducted standardized field investigations along tree line across the TPR to collect small mammals. We sequenced CYTB gene and obtained morphological measurements from field samples to calculate frequently used taxonomic, phylogenetic, and functional diversity metrics.
Results: We found that indices derived using presence/absence and abundance-based data gave discrepant results, indicating using traditional richness metrics are limited in describing diversity distribution patterns. Taxonomic and phylogenetic diversity showed similar distribution patterns, whereas different distribution was found for functional diversity. Compared with Gaoligong and Yunling mountains, Nushan showed the highest diversity levels in most of the metrics and dimensions at the transect scale, and lowest level in functional redundancy.
Conclusions: To comprehensively preserve evolutionary history and ecological functions requires simultaneous consideration of multi-dimensional biodiversity. Further research and conservational efforts should be imposed in the Nushan area. The study contributed to bridge knowledge gap of alpine ecosystems in the TPR, providing insight of the conservation of alpine biomes under contemporary climate change.

Key words: sky island, α-diversity, ecosystem functioning, climate change, biodiversity conservation
