Isotopic Ordering in Eggshells Reflects Body Temperatures and Suggests Differing Thermophysiology in Two Cretaceous Dinosaurs [PDF]

open access: yes, 2015
Our understanding of the evolutionary transitions leading to the modern endothermic state of birds and mammals is incomplete, partly because tools available to study the thermophysiology of extinct vertebrates are limited.

Effects of Climate Warming on Consumer-Resource Interactions: A Latitudinal Perspective

open access: yesFrontiers in Ecology and Evolution, 2019
There is increasing evidence that climate warming is impacting biodiversity by disrupting species interactions. Trophic (consumer-resource) interactions, which comprise the fundamental units (modules) of food webs, are of particular importance because ...

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.

Thermal ecology and baseline energetic requirements of a large‐bodied ectotherm suggest resilience to climate change

open access: yesEcology and Evolution, 2021
Most studies on how rising temperatures will impact terrestrial ectotherms have focused on single populations or multiple sympatric species. Addressing the thermal and energetic implications of climatic variation on multiple allopatric populations of a ...

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.

Latitudinal Variation in Seasonal Activity and Mortality in Ratsnakes (Elaphe obsoleta)

open access: yes, 2010
The ecology of ectotherms should be particularly affected by latitude because so much of their biology is temperature dependent. Current latitudinal patterns should also be informative about how ectotherms will have to modify their behavior in response ...

Seasonal change in acclimatised respiration rate of Temora longicornis [PDF]

open access: yes, 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 ...

Climate change from an ectotherm perspective: evolutionary consequences and demographic change in amphibian and reptilian populations

open access: yesBiodiversity and Conservation
Understanding how natural populations will respond to contemporary changes in climate is becoming increasingly urgent and of fundamental importance for the preservation of future biodiversity. Among vertebrates, amphibians and reptiles are more sensitive
