Ecophysiology of a small ectotherm tracks environmental variation along an elevational cline

Journal of Biogeography, 2022
Physiological responses to climate can be used to quantify the environmental limits that a species can tolerate and are, therefore, key to biogeographical studies.

Two stressors are worse than one: combined heatwave and drought affect hydration state and glucocorticoid levels in a temperate ectotherm.

Journal of Experimental Biology, 2022
Heatwaves and droughts are becoming more intense and frequent with climate change. These extreme weather events often occur simultaneously and may alter organismal physiology, yet their combined impacts remain largely unknown.

Limited plasticity in thermally tolerant ectotherm populations: evidence for a trade-off

Proceedings of the Royal Society B, 2021
Many species face extinction risks owing to climate change, and there is an urgent need to identify which species' populations will be most vulnerable. Plasticity in heat tolerance, which includes acclimation or hardening, occurs when prior exposure to a

Behavioral fever in ectothermic vertebrates [PDF]

Developmental & Comparative Immunology, 2017
Fever is an evolutionary conserved defense mechanism which is present in both endothermic and ectothermic vertebrates. Ectotherms in response to infection can increase their body temperature by moving to warmer places. This process is known as behavioral fever.

‘Aerobic scope protection’ reduces ectotherm growth under warming

Functional Ecology, 2021
Temperature has a dramatic effect on the physiology of ectothermic animals, impacting most of their biology. When temperatures increase above optimal for an animal, their growth gradually decreases. The main mechanism behind this growth rate reduction is

Cheating the locals: invasive mussels steal and benefit from the cooling effect of indigenous mussels [PDF]

, 2016
The indigenous South African mussel Perna perna gapes during periods of aerial exposure to maintain aerobic respiration. This behaviour has no effect on the body temperatures of isolated individuals, but when surrounded by conspecifics, beneficial ...

A warmer environment can reduce sociability in an ectotherm

Global Change Biology, 2022
The costs and benefits of being social vary with environmental conditions, so individuals must weigh the balance between these trade‐offs in response to changes in the environment. Temperature is a salient environmental factor that may play a key role in

Rapid Range Expansion of a Marine Ectotherm Reveals the Demographic and Ecological Consequences of Short-Term Variability in Seawater Temperature and Dissolved Oxygen

American Naturalist, 2021
The distributions of marine ectotherms are governed by physiological sensitivities to long-term trends in seawater temperature and dissolved oxygen. Short-term variability in these parameters has the potential to facilitate rapid range expansions, and ...

A Smart Camera Trap for Detection of Endotherms and Ectotherms

Sensors, 2022
Current camera traps use passive infrared triggers; therefore, they only capture images when animals have a substantially different surface body temperature than the background. Endothermic animals, such as mammals and birds, provide adequate temperature

Climate change and ageing in ectotherms [PDF]

Global Change Biology, 2020
AbstractHuman activity is changing climatic conditions at an unprecedented rate. The impact of these changes may be especially acute on ectotherms since they have limited capacities to use metabolic heat to maintain their body temperature. An increase in temperature is likely to increase the growth rate of ectothermic animals, and may also induce ...
