Spatial patterns in the size of Chinese lizards are driven by multiple factors
Ecology and Evolution, 2021 Background For almost two centuries, ecologists have examined geographical patterns in the evolution of body size and the associated determinants.

Control of Breathing in Ectothermic Vertebrates
Comprehensive Physiology, 2022 AbstractThe ectothermic vertebrates are a diverse group that includes the Fishes (Agnatha, Chondrichthyes, and Osteichthyes), and the stem Tetrapods (Amphibians and Reptiles). From an evolutionary perspective, it is within this group that we see the origin of air‐breathing and the transition from the use of water to air as a respiratory medium. This is

Functional Ecology, 2021 Predicting the implications of ongoing ocean climate warming demands a better understanding of how short-term thermal variability impacts marine ectotherms, particularly at beyond-optimal average conditions during summer heatwaves.

Thermal melanism in ectotherms [PDF]
Journal of Thermal Biology, 2007 Abstract Whether melanism plays a significant role in thermoregulation has been a persistent question in studies of thermal biology of ectotherms. This review provides a synthesis of the thermal melanism hypothesis which states that dark individuals (i.e.

Climate Change, Extreme Temperatures and Sex-Related Responses in Spiders
Biology, 2023 Climatic extremes, such as heat waves, are increasing in frequency, intensity and duration under anthropogenic climate change. These extreme events pose a great threat to many organisms, and especially ectotherms, which are susceptible to high ...

The likely effects of thermal climate change on vertebrate skeletal muscle mechanics with possible consequences for animal movement and behaviour [PDF]
, 2019 Climate change can involve alteration in the local temperature that an animal is exposed to, which in turn may affect skeletal muscle temperature.

Body temperatures of modern and extinct vertebrates from ^(13)C-^(18)O bond abundances in bioapatite [PDF]
, 2010 The stable isotope compositions of biologically precipitated apatite in bone, teeth, and scales are widely used to obtain information on the diet, behavior, and physiology of extinct organisms and to reconstruct past climate.

PLoS ONE, 2021 Thermoregulation is critical for ectotherms as it allows them to maintain their body temperature close to an optimum for ecological performance. Thermoregulation includes a range of behaviors that aim at regulating body temperature within a range ...

Non-Mammalian Vertebrates: Distinct Models to Assess the Role of Ion Gradients in Energy Expenditure
Frontiers in Endocrinology, 2017 Animals store metabolic energy as electrochemical gradients. At least 50% of mammalian energy is expended to maintain electrochemical gradients across the inner mitochondrial membrane (H+), the sarcoplasmic reticulum (Ca++), and the plasma membrane (Na ...

Age and heat stress as determinants of telomere length in a long-lived fish, the Siberian Sturgeon [PDF]
, 2016 Telomeres shorten at each cell division due to the end-replication problem but also in response to oxidative stress. Consequently, telomeres shorten with age in many endotherms, and this shortening is accelerated under stressful environmental conditions.
