Understanding the mechanisms underlying the temporal stability of ecological systems remains a challenge. Although temporal stability in populations is posited to emerge from the interplay between intrinsic and extrinsic factors, the nature of these interactions remains poorly understood. Here, we analysed abundance time‐series for 7912 populations from 287 fish species across 1557 streams spanning multiple biogeographic realm...

Climate change threatens biodiversity when species cannot tolerate, adapt to, or track shifting environmental conditions to stay within their climatic niches. A major unresolved question is whether and how species' genetic diversity modulates these dynamics, buffering against range contractions or facilitating range expansions. To test this, we integrated the largest global databases of species range shifts and genetic diversi...
