Adaptive divergence in reproductive seasonality and underlying physiological features fit Rattus norvegicus to live as opportunistic breeders

open access: yesIntegrative Zoology, Volume 20, Issue 4, Page 817-835, July 2025.
Brown rats living at different latitudes have evolved reproductive patterns adapted to their local environments. Besides expected adaptive divergence in seasonality, a distinct regulating mechanism from typical seasonal breeders reveals how brown rats benefit from quicker semen production to live as opportunistic breeders.

Skin development in the gray short‐tailed opossum (Monodelphis domestica)—From skin respiration to thermoregulation

open access: yesJournal of Anatomy, Volume 247, Issue 1, Page 108-133, July 2025.
The skin development in the gray short‐tailed opossum (Monodelphis domestica) has been examined using histological, morphometric, and μCT methods. During a long period of postnatal development, the structural differentiation of the skin results in a functional shift from transcutaneous gas exchange to thermoregulation in later life.
