... diffusion and evaporation of water from the skin under warm conditions when cutaneous perfusion is reduced. Testing this hypothesis may confirm a previously unappreciated adaptive role for C-value variation in this group, and reveals the possibility that genome size influences physiological exchange across...

...Christine Elizabeth Cooper; Philip Carew Withers ABSTRACT We present two independent lines of evidence that a tiny dasyurid marsupial, the ningaui ( Ningaui spp.), has acute physiological control of its insensible evaporative water loss below and within thermoneutrality. Perturbation of the driving...

... insect groups suggest a difference not only in the chemical composition of the fluid, but also in its physical properties. In the present study, we have measured for the first time changes in the droplet geometry over time and the evaporation rate of the fluid in flies ( Calliphora vicina ) and beetles...

... metabolic water production during flight, counteracted by high evaporative and excretory losses. Water fluxes at the colony level can also be very high. When incoming nectar is dilute, honeybees need to remove large volumes of water by evaporation. On the other hand, water is not stored in the nest and must...

... facilitates evaporation of water trapped within the seals' pelages due to increased saturation vapour pressure. The comparatively large latent heat necessary for evaporation creates a temporary hot spot for heat dissipation. * Author for correspondence (e-mail: mauck@neurobiologie.ruhr-uni-bochum.de...

...Blair O. Wolf; Glenn E. Walsberg ABSTRACT We measured rates of respiratory and cutaneous evaporative water loss as a function of air temperature in a small desert bird, the verdin Auriparus flaviceps . Birds were placed in a two-compartment metabolic chamber that separately collected water...
