The species that compose local communities possess unique sets of functional and ecological traits that can be used as indicators of biotic and abiotic variation across space and time. Body size is a particularly relevant trait because species with different body sizes typically have different life history strategies and occupy distinct niches. Here we used the body sizes of non-volant (i.e., non-flying) terrestrial mammals to quantify and compare the body size disparity of mammal communities across the globe.

调查非 vol 性陆生哺乳动物群落体型差异的生物和非生物驱动因素


构成当地群落的物种具有独特的功能和生态特征，可用作跨空间和时间的生物和非生物变异的指标。体型是一个特别相关的特征，因为不同体型的物种通常具有不同的生活史策略并占据不同的生态位。在这里，我们使用非自愿（即非飞行）陆生哺乳动物的体型来量化和比较全球哺乳动物群落的体型差异。
