Can we predict ectotherm responses to climate change using thermal performance curves and body temperatures?
TLDR
The key assumptions underlying the integration of TPCs with Tb are examined to develop a framework within which empiricists can place their work within these limitations, and to facilitate the application of thermal physiology to understanding the biological implications of climate change.
Heat-Shock Protein 70 (Hsp70) Expression in Four Limpets of the Genus Lottia: Interspecific Variation in Constitutive and Inducible Synthesis Correlates With in situ Exposure to Heat Stress
TLDR
The findings suggest that high-intertidal congeners of Lottia employ a “preparative defense” strategy involving maintenance of high constitutive levels of Hsp70 in their cells as a mechanism for protection against periods of extreme and unpredictable heat stress.
Effects of diel temperature fluctuations on growth, oxygen consumption and proximate body composition in the sea cucumber Apostichopus japonicus Selenka
TLDR
Growth of juveniles varied at different constant temperatures and diel fluctuating temperatures as well as proximate body composition and oxygen consumption of juvenile sea cucumbers.
Thermal adaptation in the intertidal snail Echinolittorina malaccana contradicts current theory by revealing the crucial roles of resting metabolism
TLDR
A hypothetical framework for thermal performance of locomotor activity and resting metabolism in energetically compromised snails in the littoral fringe zone points to the need to incorporate aspects of resting metabolism and energy conservation into theories of thermal adaptation.
Optimization of stocking density for the sea cucumber, Apostichopus japonicus Selenka, under feed-supplement and non-feed-supplement regimes in pond culture
TLDR
The average survival rates of sea cucumbers under feed-supplement regime were higher than those under non-feed-Supplement regime for both the autumn phase and spring phase, but the differences were only significant for the latter phase.
Beyond long-term averages: making biological sense of a rapidly changing world
Biological responses to climate change are typically communicated in generalized terms such as poleward and altitudinal range shifts, but adaptation efforts relevant to management decisions often
Adaptations of protein structure and function to temperature: there is more than one way to ‘skin a cat’
TLDR
It is found that approaches employing algorithms that calculate changes in protein stability in response to a mutation have the potential to help predict temperature adaptation in enzymes, but that the algorithms tested currently lack the sensitivity to detect the small changes in flexibility that are central to enzyme adaptation to temperature.
Metabolic energy sensors (AMPK and SIRT1), protein carbonylation and cardiac failure as biomarkers of thermal stress in an intertidal limpet: linking energetic allocation with environmental
TLDR
Results show that C. toreuma commonly experiences temperatures that induce expression of genes associated with the stress response and regulation of energy metabolism (ampk and sirt1), which indicates a shift away from anabolic processes such as growth to catabolic processes, to provide energy for coping with stress-induced damage.
The Impact of Yangtze River Discharge, Ocean Currents and Historical Events on the Biogeographic Pattern of Cellana toreuma along the China Coast
TLDR
It is proposed that freshwater discharge from the Yangtze River is especially important in determining the separation of the YS group from the rest of the Chinese populations of C. toreuma, which was relatively isolated from ECS and SCS.
Variations in cardiac performance and heat shock protein expression to thermal stress in two differently zoned limpets on a tropical rocky shore
TLDR
Temperature-adaptive differences in cardiac thermal tolerance and Hsp expression match observed differences in thermally induced mortalities with the onset of summer and may help predict differential effects of climate change on the two congeners.
