[News Feed] Evolution Of Morphological Integration: Developmental Accommodation Of Stress-induced Variation

[Forum Mouse]

In an article in the September issue of The American Naturalist, Alexander V. Badyaev (University of Arizona) and colleagues show that complexity and cohesiveness of foraging structures of shrews enables accommodation of stress-induced developmental abnormalities in individual components of morphological complexes. Such developmental compensation and accommodation not only allow shrews growing under stressful environments to maintain locally adaptive foraging morphology, but also provide a mechanism for stress-induced evolutionary change.
