FOLK,D.F.*; BRADLEY,T.J.: How Does Selection for Desiccation Resistance Affect the Distribution of Water in Drosophila melanogaster? We are conducting experiments with five populations of Drosophila melanogaster, which have undergone laboratory selection for increased desiccation resistance for over 200 generations. For each population of desiccation-resistant flies (D flies), a control population (C flies) was maintained under […]

CLAIBORNE, J.B.*; GUNNING, D.L.; WALL, B.P.; MORRISON-SHETLAR, A.I.: Gill Na+/H+ antiporters (NHE) in marine fish The branchial epithelium in marine fish is the main site of acid-base transfers between the extracellular space and the environment. Na+/H+ exchange proteins (NHE) are thought to contribute to net acid excretion in these animals. We have used molecular and […]

LILLYWHITE, H.B.; TU, M.C.: First Ecdysis Increases Skin Resistance to Evaporative Water Loss in Newborn Snakes Aquatic-terrestrial transitions associated with nativity present numerous physiological challenges for terrestrial vertebrates, one being the requirement to limit excessive losses of water due to evaporation. Epidermal water barriers comprised of lipids prevent excessive water loss in the adults of […]

Lotz, C.N.: Effects of nectar concentration on water balance, osmoregulation, and thermoregulation in a nectar-feeding sunbird The water balance of nectar-feeding animals is inextricably linked to their energy balance. Because nectar secreted by bird-pollinated flowers can be dilute, birds can be forced to consume high volumes of water to satisfy their energy demands. I examined […]

Piermarini, P.M.*; Evans, D.H.: Effect of salinity on expression of the vacuolar proton-ATPase B-subunit in the gills of a euryhaline stingray (Dasyatis sabina) The vacuolar proton-ATPase (V-H-ATPase) is an important ion transporter that is responsible for energizing a variety of active transport processes in animals. Recently, the V-H-ATPase has been considered alikely transporter for driving […]
