Adaptations to an extreme environment: retinal organisation and spectral properties of photoreceptors in Antarctic notothenioid fish.
The Notothenioid suborder of teleosts comprises a number of species that live below the sea ice of the Antarctic. The presence of 'antifreeze' glycoproteins in these fish as an adaptation to freezing temperature has been well documented but little is known about the adaptations of the visual system of these fish to a light environment in which both the quantity and spectral composition of downw...
متن کاملMolecular adaptations of lipolysis to physical activity
The purpose of the present study was to investigate the context of lipid metabolism research in physical activity, lipolysis, lipolysis hormone regulation and the fate of lipolysis products in exercise, fatty acid transporters, some genes involved in lipid metabolism, effect of resistance activity on lipolysis, adaptations of adipose tissue due to physical activity, lipoproteins and apoproteins...
متن کاملEditorial: Physiological Adaptations to Swimming in Fish
Swimming is an integral part of the life history of many fish species as is intimately linked with their ability to express feeding and predator avoidance behaviors, habitat selection and environmental preferences, social and reproductive behaviors as well as migratory behaviors (Videler, 1993; Palstra and Planas, 2011). Therefore, swimming is an important determinant factor of fitness in a tru...
متن کاملOxygen-limited thermal tolerance in Antarctic fish
Mark, F. C., C. Bock, and H. O. Pörtner. Oxygen limited thermal tolerance in Antarctic fish investigated by MRI and 31P-MRS. Am J Physiol Regul Integr Comp Physiol 283: R1254–R1262, 2002. First published August 8, 2002; 10.1152/ajpregu.00167.2002.—The hypothesis of an oxygenlimited thermal tolerance was tested in the Antarctic teleost Pachycara brachycephalum. With the use of flow-through respi...
متن کاملProteorhodopsin-bearing bacteria in Antarctic sea ice.
Proteorhodopsins (PRs) are widespread bacterial integral membrane proteins that function as light-driven proton pumps. Antarctic sea ice supports a complex community of autotrophic algae, heterotrophic bacteria, viruses, and protists that are an important food source for higher trophic levels in ice-covered regions of the Southern Ocean. Here, we present the first report of PR-bearing bacteria,...
