Code from: The relative influence of climate extremes and species richness on the temporal variability of bird communities
收藏资源简介：
Understanding the relationship between biodiversity and ecological stability is increasingly urgent as rapid species extinction continues. Though evidence of positive diversity-stability relationships is accumulating, empirical results are inconsistent and effect sizes tend to be small, raising questions about relative contributions of intrinsic (i.e., species composition/interactions) and extrinsic (i.e., environmental) drivers of stability. Community stability may be more strongly influenced by environmental conditions than by community diversity in some contexts, yet little is known about the comparative importance of diversity and climate means, extremes, and variability in regulating stability. We used a half-century of continental-scale bird data to quantify avian community temporal variability (a metric often used to approximate ecological stability) at 1,379 sites and compared relative effects of climatic variables and species richness. We found that extreme heat and extremely l..., , , # Code from: The relative influence of climate extremes and species richness on the temporal variability of bird communities Date: Mar 30, 2023 Lead author contact: Samantha M.
