    Deterministic processes drive turnover-dominated beta diversity of breeding birds along the central Himalayan elevation gradient by Zhifeng Ding, Jianchao Liang, Le Yang, Cong Wei, Huijian Hu, Xingfeng Si

    Published 2024-01-01
    “…Here, we simultaneously consider distance-decay models and multiple dimensions of beta diversity to examine spatial variations of bird communities, and to evaluate the relative importance of niche-based and neutral community assembly mechanisms along a 3600-m elevational gradient in the central Himalayas, China. Our results showed that species turnover dominates taxonomic, functional, and phylogenetic beta diversity. …”
