Big City Living: A Global Meta-Analysis Reveals Positive Impact of Urbanization on Body Size in Lizards

open access: yesFrontiers in Ecology and Evolution, 2020
Urban environments pose different selective pressures than natural ones, leading to changes in animal behavior, physiology, and morphology. Understanding how animals respond to urbanization could inform the management of urban habitats.

Oxidative phosphorylation efficiency, proton conductance and reactive oxygen species production of liver mitochondria correlates with body mass in frogs [PDF]

open access: yes, 2015
ody size is a central biological parameter affecting most biological processes (especially energetics) and mitochondria is a key organelle controlling metabolism and is also the cell's main source of chemical energy.

Body temperatures of modern and extinct vertebrates from ^(13)C-^(18)O bond abundances in bioapatite [PDF]

open access: yes, 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.

Diurnal temperature variations affect development of a herbivorous arthropod pest and its predators [PDF]

open access: yes, 2015
The impact of daily temperature variations on arthropod life history remains woefully understudied compared to the large body of research that has been carried out on the effects of constant temperatures. However, diurnal varying temperature regimes more

The influence of ecological and life history factors on ectothermic temperature–size responses: Analysis of three Lycaenidae butterflies (Lepidoptera)

open access: yesEcology and Evolution, 2019
Body size has been shown to decrease with increasing temperature in many species, prompting the suggestion that it is a universal ecological response.

Spatial patterns in the size of Chinese lizards are driven by multiple factors

open access: yesEcology and Evolution, 2021
Background For almost two centuries, ecologists have examined geographical patterns in the evolution of body size and the associated determinants.

A Smart Camera Trap for Detection of Endotherms and Ectotherms

open access: yesSensors, 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

Age and heat stress as determinants of telomere length in a long-lived fish, the Siberian Sturgeon [PDF]

open access: yes, 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.
