Biophysical and Physiological Responses Promoting Freeze Tolerance in Vertebrates
Amphibians and reptiles inhabiting temperate areas are confronted with seasonal cold from which they seek refuge within thermally buffered aquatic or terrestrial microenvironments. However, some species, particularly those that overwinter in relatively shallow and poorly insulated hibernacula, are exposed to subzero temperatures. Organisms may survive such episodes by avoiding crystallization (...
متن کاملIce Nucleation in Freeze - Tolerant Vertebrates
The survival of freeze-tolerant vertebrates requires that ice nucleation in tissues be initiated at relatively high temperatures. Three current hypotheses for the initiation of freezing in these animals are: a) inoculation by contact with ice crystals in the external environment; b) nucleation by ice-nucleating bacteria associated with the animal; and c) nucleation by icenucleating proteins in ...
متن کاملDiving Physiology of Marine Vertebrates
Air-breathing marine vertebrates that dive to find food deal with two fundamental problems, the effects of pressure at depth, and the need to actively forage while breathholding. Adaptations to diving can be divided into two categories, those that are associated with adaptations to pressure, and those associated with breath-hold diving. Adaptations to pressure have to deal with the mechanical e...
متن کاملPhysiology and molecular biology of salinity stress tolerance in plants
The productivity of plants is greatly affected by various environmental stresses. Soil salinity affects plant growth and development by way of osmotic stress, injurious effects of toxic Na and Cl – ions and to some extent Cl – and SO4 2 – of Mg and nutrient imbalance caused by excess of Na and Cl – ions. Salinity stress response is multigenic, as a number of processes involved in the tolerance ...
متن کاملPhysiology of cell volume regulation in vertebrates.
The ability to control cell volume is pivotal for cell function. Cell volume perturbation elicits a wide array of signaling events, leading to protective (e.g., cytoskeletal rearrangement) and adaptive (e.g., altered expression of osmolyte transporters and heat shock proteins) measures and, in most cases, activation of volume regulatory osmolyte transport. After acute swelling, cell volume is r...
