Survival, osmoregulatory pattern, oxygen consumption, energy spent on metabolism, ammonia excretion, type of oxidized energy substrate, and hepatosomatic index were evaluated in decapods (an osmoregulating crab, Callinectes ...

The leptodactylid frog Thoropa miliaris, from SE Brazil, may live on rocky marine shore, where it thrives on terrestrial and marine invertebrates, and often moves into the intertidal zone. The osmotic concentration of ...

Cellular osmoregulation constitutes a phylogenetically conserved set of highly complex responses to changes in external osmolality/tonicity to maintain cell volume, intracellular concentrations of macro- and micromolecules, ...

Studies of aquatic invertebrates reveal that salinity affects feeding and growth rates, reproduction, survival, and diversity. Little is known, however, about how salinity impacts the energy budget of vertebrates and ...

When a species often experiences variation in its environmental conditions, metabolic flexibility is required. We studied the duration of the digestive cycle and the activity of key digestive enzymes (proteolytic, amylase, ...
