Effects of environmental temperature on oxygen diffusion capacity during post-natal development in the altricial rodent, Phyllotis darwini

In this contribution we studied the developmental phenotypic plasticity of respiratory structures involved in the exchange of gases in an altricial rodent, the leaf-eared mouse {Phyllotis darwini). We studied morphological pulmonary parameters of warm (30 °C) and cold acclimated animals 15 °C) at di...
