Testing for Functional Adaptation in a Genital Bone: Baculum Size, Shape, and Microstructure Show Little Plastic Response to Mating Across Five Rodent Species.
Plasticity-the ability of a genotype to produce different phenotypes in response to environmental input-can provide insight into the mechanical forces experienced by biological structures. Bones are particularly plastic, remodeling in response to sustained and repetitive mechanical stress. In many mammals, males posses...
