Heat tolerance and cold indifference in the short-beaked echidna, Tachyglossus aculeatus: body temperature management in a mammalian constitutional eurytherm.
- Environmental Science, Biology
- 2007
This project investigated physiological adjustments that allow echidnas to tolerate ambient temperatures in the field that would be lethally high in laboratories and developed integrated parameter, a priori heat budget modelling to predict body temperature responses of animals in general to combined variations of metabolic heat production, thermal conductance and other physiological factors in dynamically fluctuating thermal environments.
Heat loss from giant extinct reptiles
- Environmental ScienceProceedings of the Royal Society of London. Series B: Biological Sciences
- 2001
It is shown that, in most circumstances, the rate at which heat is lost by a large body is significantly greater when it is immersed in water than whenIt is surrounded by air, assuming that the two fluids are at the same temperature.
Nocturnality in synapsids predates the origin of mammals by over 100 million years
- Biology, Environmental ScienceProceedings of the Royal Society B: Biological Sciences
- 2014
Recognizing the complexity of diel activity patterns in non-mammalian synapsids is an important step towards a more nuanced picture of the evolutionary history of behaviour in the synapsid clade.
Positive Allometry and the Prehistory of Sexual Selection
- Environmental Science, BiologyThe American Naturalist
- 2010
The results question the popular view that the elaborated structures of these fossil species evolved as thermoregulatory organs and provide evidence in support of the hypothesis that Pteranodon crests and eupelycosaur sails are among the earliest and most extreme examples of elaborate sexual signals in the evolution of terrestrial vertebrates.
Variation in tail morphology across urban and forest populations of the crested anole (Anolis cristatellus)
- Environmental ScienceBiological Journal of the Linnean Society
- 2019
It is found that tail crest size differs primarily between regions; however, within regions, crests are invariably larger in urban than in forest environments, leading to the intriguing possibility that the tail crest might be under differential natural selection for signalling and/or because of the thermoregulatory challenge of urban habitats.
Healed Fractures in the Neural Spines of an Associated Skeleton of Dimetrodon: Implications for Dorsal Sail Morphology and Function
- Biology
- 2012
The distal morphology of spines in more complete specimens, including the type fmnh UC 112 and omnh 01727, suggests that the dorsal margin of the sail was located well proximal to the tips of the elongate neural spines, and the cross-sectional architecture of the spines suggests a further hypothesis: that the proximal portion of the sails may have also functioned as an energy storage device, facilitating fast locomotion in this top predator.
Identifying large herbivore distribution mechanisms through application of fine-scale snow modeling
- Environmental Science

Climatic variation can influence species responses to the environment by changing landscape conditions at fine spatial scales over short time periods. Snowpack has recently been modeled in a…
Effects of Different Treatments of Salicylic Acid on Heat Tolerance, Chlorophyll Fluorescence, and Antioxidant Enzyme Activity in Seedlings of Cucumis sativa L.
- ChemistryPlant Growth Regulation
- 2005
The effects of different treatments of salicylic acid (SA) on lipid peroxidation, chlorophyll fluorescence and antioxidant enzyme activity in seedlings of Cucumis sativa L. were studied before heat…
Long bone histology indicates sympatric species of Dimetrodon (Lower Permian, Sphenacodontidae)
- Environmental ScienceEarth and Environmental Science Transactions of the Royal Society of Edinburgh
- 2012
Histological analysis of newly excavated material from the Briar Creek Bonebed has resolved some of the discretion between these two competing hypothesis, confirming the coexistence of a small (D. natalis) with at least one larger Dimetrodon species.

A Mathematical Model for Body Temperatures of Large Reptiles: Implications for Dinosaur Ecology
- Environmental ScienceThe American Naturalist
- 1973
These calculations show that a large reptile would have a relatively constant high body temperature when exposed to warm, diurnally fluctuating environmental conditions, even with a low metabolic rate, as long as the average values of the physical parameters result in a body temperature within tolerable limits.
A thermal model of the sailback pelycosaur
- Environmental Science
- 1986
Standard techniques of energy exchange analysis are applied to modelling the thermal regimes of several species of sailback pelycosaurs. Of particular interest is the role played by the sail in…
Control of Changes in Body Temperature, Metabolism, and Circulation by the Agamid Lizard, Amphibolurus barbatus
- BiologyPhysiological Zoology

Limited capacity for physiological thermoregulation may exist, and since such a capacity could have theoretical implications for the evolution of homeothers, this work considers whether this capacity should be focused onizards or other reptiles.
PHYLOGENETIC STUDIES OF COADAPTATION: PREFERRED TEMPERATURES VERSUS OPTIMAL PERFORMANCE TEMPERATURES OF LIZARDS
- BiologyEvolution; international journal of organic evolution

A comparative study of evolutionary patterns in thermal preferences and the thermal dependence of sprinting in some Australian skinks suggests that low thermal preferences can evolve, even if this results in reduced performance.

The positive mass-dependence of acid-base disturbance could be related to the greater susceptibility of large crocodiles (>700kg) to postcapture mortality.
