The critical thermal maximum: history and critique
A literature review of previous studies to describe the history of the study of thermal tolerance and show the chronological trends in the use of lethal temperature and critical thermal maximum methods and illustrate the diversity of taxa used in thermal-tolerance studies.
The critical thermal maximum: data to support the onset of spasms as the definitive end point
Data is provided to support the onset of spasms (OS) as the definitive end point for determining thermal tolerance with the critical thermal maximum (CTMax) and the CTMax is measured.

Investigation of seasonal and reproductive variation in basal and stress-induced hormone profiles in a population of free-ranging timber rattlesnakes in north-central Pennsylvania suggests that the sensitivity of the hypothalamus–pituitary–adrenal axis varies both seasonally and with changing reproductive states.

Investigation of thermoregulation and habitat use in two sympatric lizard species of the family Phrynosomatidae in southern New Mexico found side-blotched lizards Uta stansburiana and S. arenicolus had a slightly higher preferred temperature and micro- and macro-habitat use for these species was compared.

Although sex differences in dorsal cortex volume were not observed, males had a significantly larger medial cortex relative to telencephalon volume, and relative hippocampal or medial cortex volume was positively correlated with patterns of spatial use.
Modeling body temperature and thermal inertia of large-bodied reptiles: Support for water-filled biophysical models in radiotelemetric studies
Data is provided from three independent experiments that support the additional use of water-filled biophysical models to more accurately model the body temperature and thermal inertia of larger-sized free-ranging reptiles.
Locomotor Performance in Juvenile and Adult Box Turtles (Terrapene carolina): A Reanalysis for Effects of Body Size and Extrinsic Load Using a Terrestrial Species
The relationship between body size and locomotor performance was investigated and sprint speed in some iguanid and helodermatid species is mass independent, while in other species it increases with body mass.
Seasonal and Long-Term Changes in the Fish Assemblage of a Small Stream Isolated by a Reservoir
TEMPERATURE | Measures of Thermal Tolerance
Of the various methods used to estimate thermal tolerances in fishes, the lower or upper incipient lethal temperature method (static temperature) and critical thermal minimum or maximum method (dynamic temperature) are the two most widely used and accepted.
Modeling energetic and theoretical costs of thermoregulatory strategy
This work modelled movement patterns between an active and non-active shuttling behaviour within a habitat to investigate the potential cost of two thermoregulatory strategies and modelled movements and the resulting and comparative energetic costs in precisely maintaining a T set for a small-bodied versus large-bodied ectotherm to study and evaluate the thermoregian strategy.
