The ability of southern killifish to upregulate hsc70 in response to heat shock suggests a possible role for these hsps in whole-organism differences in thermal tolerance, and highlights the importance of considering the complexity of the heat shock response across multiple isoforms when attempting to make linkages to whole- Organism traits such as thermal tolerance.

Examples from the work on common killifish are used to illustrate some important conceptual issues relating to TPCs in the context of using these curves to predict the responses of organisms to climate change.

The data indicate that the plasticity of mitochondrial function and amount differs between killifish subspecies, with the less high-temperature tolerant, and putatively cold adapted, northern subspecies having greater ability to increase mitochondrial capacity in the cold.
Ocean acidification alters skeletogenesis and gene expression in larval sea urchins
The results suggest that, although larvae are able to form an endoskeleton, development at elevated CO2 levels has consequences for larval physiology as shown by changes in the larval transcriptome.
Thermal Tolerance Responses of Laboratory-Acclimated and Seasonally Acclimatized Atlantic Stingray, Dasyatis sabina
Similar to laboratory responses, seasonally acclimatized Atlantic stingrays tuned their physiology to the low cycle temperatures that were most threatening to continued survival.

Behavioral thermoregulation can allow ectotherms to buffer the effects of changes in environmental temperature, and thus an organism’s preferred temperature is thought to be under strong selection.…
Ontogeny influences sensitivity to climate change stressors in an endangered fish
Thermal tolerance decreased among successive stages, and juvenile tolerance limits were closest to current environmental conditions, and salinity impacted juvenile and adult survival in exposures over acute timescales.
A laboratory‐based, experimental system for the study of ocean acidification effects on marine invertebrate larvae

An experimental system that unites the culturing needs of larval invertebrates with methods for careful control, monitoring, and manipulation of seawater carbonate chemistry necessary to conduct laboratory-based studies of ocean acidification is presented.
Gene expression responses of threespine stickleback to salinity: implications for salt-sensitive hypertension
Threespine sticklebacks may be used as a model, complementary to existing animal models, in human HTN research, and it is shown that stickleback salt-responsive genes provide valuable information facilitating the identification of humanHTN genes.

A transcriptional analysis of gill tissue from Chinook salmon juveniles reared at 12° and exposed acutely to water temperatures ranging from ideal to potentially lethal shows the complex multi-modal cellular response to thermal stress in juvenile salmon.
