Biome shifts are thought to be relatively rare, but some clades shift among starkly different environments with relative ease. What causes these shifts, and how do they shape phenotypic evolution? Roycroft et al. found that biome shifts in the Pseudomys Division of murid rodents were repeatedly accompanied by body size evolution in accordance with Bergmann's rule, suggesting adaptive evolution in response to changing climate conditions.

文摘：澳大利亚啮齿动物的环境与体型之间的进化关系

生物群落转变被认为是相对罕见的，但一些进化枝在截然不同的环境中相对容易地转变。是什么导致了这些变化，它们如何影响表型进化？罗伊克罗夫特等人。发现鼠类啮齿动物 Pseudomys Division 的生物群落变化反复伴随着符合 Bergmann 规则的体型进化，这表明适应性进化是为了响应不断变化的气候条件。
