The circadian system alters thermoregulation depending on the time of day and feeding condition [PDF]

open access: yes, 2009
The circadian rhythm of body temperature (Tb) is a well-known phenomenon. However, it is unknown how the circadian system affects thermoregulation. Food deprivation in mice induces a greater reduction of Tb particularly in the light phase.

An Overlooked Habitat‐Dependent Link Between Metabolism and Water Loss in Reptiles

open access: yesIntegrative Zoology, EarlyView.
We measured the gas exchange of six lizard and six snake species, under high and low air humidity, and two intriguing patterns emerged. First, although desert species lose less water via evaporation than similar‐sized mesic species under similar conditions, water loss is virtually the same when each is exposed to its natural conditions.

Living Low and Dry: Costs of and Resilience to Soil Hydric Stress in a Fossorial Amphisbaenian Reptile

open access: yesIntegrative Zoology, EarlyView.
Soil drought imposes moderate, temporary costs on a strictly fossorial amphisbaenian reptile. However, these animals seem to cope with, at least, moderately short droughts thanks to their peculiar adaptations to living in an underground environment. ABSTRACT The physiological traits of animals can be strongly influenced by climatic fluctuations, and ...

The metabolic cost of behavioral thermoregulation of body temperature in the northern alligator lizard Gerrhonotus coeruleus, and how it affects the classical concept of eurythermality [PDF]

open access: yes, 1981
The effect of total metabolic cost expenditures on the precision of behavioral thermoregulation was investigated for the purportedly eurythermic Northern Alligator lizard (Gerrhonotus coeruleus). An operant apparatus was designed to test metabolic output

Beyond Sexual Selection: Natural Selection Related Camouflage and Thermoregulation Shape Sexual Color Dimorphism in Diploderma Lizards

open access: yesIntegrative Zoology, EarlyView.
Integrating comparative spectrometry, image analysis, and thermal modeling, we reveal that (1) females optimize crypsis via background matching, (2) males prioritize high‐contrast disruptive patterning at a significant thermoregulatory cost (reduced solar heat gain), and (3) habitat‐specific monomorphism in Diploderma slowinskii underscores ecological ...

Effect of altered gravity on temperature regulation in mammals: Investigation of gravity effect on temperature regulation in mammals [PDF]

open access: yes
Male, Long-Evans hooded rats were instrumented for monitoring core and hypothalamic temperatures as well as shivering and nonshivering thermogenesis in response to decreased ambient temperature in order to characterize the nature of the neural controller

Blubber Thickening Driven by UCP1 Inactivation: Insights from a Cetacean‐Like Transgenic Mouse Model

open access: yesIntegrative Zoology, EarlyView.
UCP1 inactivation of cetaceans in mice drives BAT whitening and iWAT hyperplasia, promoting fat accumulation for aquatic adaptation. Abstract Cetaceans possess thick blubber, a specialized adipose tissue essential for thermal insulation, a streamlined body form, energy storage, and buoyancy. However, the mechanisms that underpin this adaptation are not
