This study develops a novel CTmax assay to compare thermal acclimation capacity across three sea urchin species, finding significant variation in their upper thermal tolerance and acclimatory responses.

Fitness effects of local seasonal adaptation depend on the timing of reproduction in a range-expanding butterfly

The paper shows that fitness effects of genetic differences in photoperiodism for diapause timing depend on egg-laying timing in a butterfly, with southern populations performing better when laying eggs early.

Thermal acclimation and resultant developmental adaptation offsets environmental temperature effects on tail muscle mechanics in larval zebrafish

This study shows that developmental temperature alters muscle mechanics in larval zebrafish to counteract environmental temperature effects on tail muscle function.

Freeze tolerance of a beneficial lady beetle, Hippodamia convergens

This study shows that the lady beetle Hippodamia convergens can tolerate freezing at high subzero temperatures and maintains normal mating behavior after freezing.

Behavioral metabolic suppression confounds thermal performance estimates and climate vulnerability assessments in a marine ectotherm

In an undescribed intertidal Urticina anemone, heat-induced closure suppresses measured respiration, and fitted thermal performance curves place the critical thermal maximum far above the 25-30°C lethal range.

Parental immune priming reshapes offspring growth, metabolism, and thermal tolerance in the Pacific Oyster

This study shows that parental immune challenge in Pacific Oysters improves offspring survival and metabolic flexibility under moderate heat stress but reduces survival at extreme temperatures.

Continuous thermal sensitivity of gene expression following acclimation in Drosophila subobscura

This study shows that gene expression in Drosophila subobscura changes continuously with acclimation temperature, not abruptly, and identifies key pathways involved in thermal adaptation.

Microbiome plasticity, not gut morphology, is linked to amphibian larval performance under elevated temperatures and low food quality

This study shows that amphibian larvae's microbiome adapts to warming and poor food, improving their performance and heat tolerance, more than changes in gut structure.

Size-invariant exercise-induced aerobic scope across a broad body mass range in a giant isopod

The paper measures aerobic scope in giant isopods across body mass and finds it remains constant despite increasing metabolic rates.

Development shapes molecular responses to thermal extremes in a desert bird

This study shows that molecular responses to heat and cold change during development in ostrich chicks, with overlapping pathways that shape genetic variation in thermoregulation.

Distinct molecular mechanisms shape thermal tolerance and its plasticity in a splash pool copepod

The paper examines thermal tolerance and its plasticity in copepods across populations, finding that higher heat tolerance correlates with stable peptidase expression, while plasticity is linked to chitin and ECM gene expression changes.
