Environmental heterogeneity shapes physiological traits in tropical direct‐developing frogs
Ecology and Evolution, 2021 Tropical ectotherm species tend to have narrower physiological limits than species from temperate areas. As a consequence, tropical species are considered highly vulnerable to climate change since minor temperature increases can push them beyond their ...

Oxygen availability and body mass modulate ectotherm responses to ocean warming
Nature Communications, 2023 In an ocean that is rapidly warming and losing oxygen, accurate forecasting of species’ responses must consider how this environmental change affects fundamental aspects of their physiology.

Seasonal change in acclimatised respiration rate of Temora longicornis [PDF]
, 2014 We investigated the seasonal changes in the respiration rate (R) of adult Temora longicornis (Müller) acclimatised to in situ conditions over 1 yr. Mean (±1 SE) R varied from 50.5 ± 2.8 nl O2 ind.-1 h-1 in December to 73.2 ± 3.53 nl O2 ind.-1 h-1 in ...

Energy intake functions of ectotherms and endotherms derived from their body mass growth [PDF]
arXiv, 2016 How animals allocate energy to different body functions is still not completely understood and a challenging topic until recently. Here, we investigate in more detail the allocation of energy intake to growth, reproduction or heat production by developing energy budget models for ectothermic and endothermic vertebrates using a mathematical approach ...

Comparative ecophysiology of a critically endangered (CR) ectotherm: Implications for conservation management. [PDF]
PLoS ONE, 2017 Captive breeding is a vital conservation tool for many endangered species programs. It is often a last resort when wild animal population numbers drop to below critical minimums for natural reproduction.

Physiological capacity of Cancer setosus larvae — Adaptation to El Niño Southern Oscillation conditions [PDF]
, 2012 Temperature changes during ENSO challenge the fauna of the Pacific South American coast. In many ectotherm benthic species pelagic larvae are the most important dispersal stage, which may, however, be particularly vulnerable to such environmental stress.

Diet effects on ectotherm thermal performance
Biological ReviewsABSTRACTThe environment is changing rapidly, and considerable research is aimed at understanding the capacity of organisms to respond. Changes in environmental temperature are particularly concerning as most animals are ectothermic, with temperature considered a key factor governing their ecology, biogeography, behaviour and physiology.

Temperature Size Rule is mediated by thermal plasticity of critical size in Drosophila melanogaster [PDF]
arXiv, 2013 Most ectotherms show an inverse relationship between developmental temperature and body size, a phenomenon known as the temperature size rule (TSR). Several competing hypotheses have been proposed to explain its occurrence. According to one set of views, the TSR results from inevitable biophysical effects of temperature on the rates of growth and ...

On the thermodynamic origin of metabolic scaling [PDF]
arXiv, 2014 The origin and shape of metabolic scaling has been controversial since Kleiber found that basal metabolic rate of animals seemed to vary as a power law of their body mass with exponent 3/4, instead of 2/3, as a surface-to-volume argument predicts. The universality of exponent 3/4 -claimed in terms of the fractal properties of the nutrient network- has ...
