Levels of Sex Steroids in Plethodontid Salamanders: A Comparative Study Within the Genus .

Derived monomorphism is a condition in which males and females are phenotypically similar, but the similarity is derived. Derived monomorphism typically evolves from sexual dimorphism or from a different monomorphic state. We examined the hormonal basis of derived monomorphism in the salamander genus (Plethodontidae).

Relaxing life of the city? Allostatic load in yellow-bellied marmots along a rural-urban continuum.

Urban environments are expanding. As rural areas are urbanized, animals living in those environments must respond. Examinations of ecological responses to urbanization are abundant, but much less work has focused on the physiological responses driving those ecological patterns, particularly in mammals.
