Biochemical Adaptation: Mechanism and Process in Physiological Evolution
This volume discusses water-Solute Adaptations: The Evolution and Regulation of the Internal Milieu, and the influence of Oxygen Availability on the Diving Response and Its Evolution.

This work states that local extinctions from heat death may be offset by in-migration of genetically warm-adapted conspecifics from mid-latitude ‘hot spots’, where midday low tides in summer select for heat tolerance.

The vertical zonation observed in rocky intertidal habitats thus may reflect two distinct yet closely related aspects of thermal physiology: intrinsic interspecific differences in temperature sensitivities of physiological systems, which establish thermal optima and tolerance limits for species; and ‘cost of living’ considerations arising from sub-lethal perturbation of these physiological systems.
Temperature Tolerance of Some Antarctic Fishes
Data on brain metabolism in vitro support the hypothesis that the central nervous system is a primary site of thermal injury in fishes living in constantly near-freezing waters.

It is demonstrated that although certain shifts in gene expression mirror changes in mammals, novel genes are differentially expressed in fish; and tissue-specific patterns of expression reflect the different metabolic roles of tissues during hypoxia.

The integrative approach suggests that the patterns of oxygen- and capacity-limited thermal tolerance are linked with the capacity and design of molecules and membranes, and, on the other hand, with life-history consequences and lifestyles typically seen in the permanent cold.
Hot spots in cold adaptation: localized increases in conformational flexibility in lactate dehydrogenase A4 orthologs of Antarctic notothenioid fishes.
Notothenioid A4-LDHs have adapted to cold temperatures by increases in flexibility in small areas of the molecule that affect the mobility of adjacent active-site structures, and a model that explains linked temperature-adaptive variation in Km and kcat is proposed.
A Comparative Analysis of the Upper Thermal Tolerance Limits of Eastern Pacific Porcelain Crabs, Genus Petrolisthes: Influences of Latitude, Vertical Zonation, Acclimation, and Phylogeny
A comparative analysis of the adaptive significance of upper thermal tolerance limits in 20 congeneric species of porcelain crabs, genus Petrolisthes, from intertidal and subtidal habitats throughout the eastern Pacific suggests that the upper thermalolerance limits of some interTidal species may be near current habitat temperature maxima, and global warming thus may affect the distribution limits of intert tidal species to a greater extent than for subtidal species.

Comparisons of congeneric marine invertebrates reveal that the most warm- Adapted species may live closer to their thermal tolerance limits and have lower abilities to increase heat tolerance through acclimation than more cold-adapted species.
