Prevalence of cutaneous evaporation in Merriam's kangaroo rat and its adaptive variation at the subspecific level by Tracy, R L, Walsberg, G E

“…Previous estimates suggested that ventilatory evaporation constitutes the major source of water loss in kangaroo rats (Dipodomys spp.). We quantified rates of…”

Unappreciated Tolerance to High Ambient Temperatures in a Widely Distributed Desert Rodent,Dipodomys merriami by Tracy, Randall L., Walsberg, Glenn E.

“…A long‐held assertion has been that nocturnality is an escape mechanism for many nocturnal desert rodents because of limited tolerances to heat. To test this…”
