Webtraits of populations, such as individual body size, may be equally important to determine the dynamics of a popula tion or community. Body size is commonly measured in experiments with larval amphibians because it is a strong predictor of metamorph size (Wilbur & Collins 1973; Scott 1990) and individual fitness (Semlitsch, Scott & Pechmann WebApr 11, 2024 · Background Among the most widely predicted climate change-related impacts to biodiversity are geographic range shifts, whereby species shift their spatial distribution to track their climate niches. A series of commonly articulated hypotheses have emerged in the scientific literature suggesting species are expected to shift their …
