Circadian and Seasonal Patterns of Body Temperature in Arctic Migratory and Temperate Non-migratory Geese

open access: yesFrontiers in Ecology and Evolution, 2021
Arctic migration presents unique challenges to circadian physiology. In addition to the metabolic cost of maintaining a relatively high body temperature (Tb) above ambient temperature, migratory birds are also exposed to rapidly changing light conditions

Living on the edge: Daily, seasonal and annual body temperature patterns of Arabian oryx in Saudi Arabia.

open access: yesPLoS ONE, 2017
Heterothermy, the ability to allow body temperature (Tb) to fluctuate, has been proposed as an adaptive mechanism that enables large ungulates to cope with the high environmental temperatures and lack of free water experienced in arid environments.

REM Sleep and Endothermy: Potential Sites and Mechanism of a Reciprocal Interference

open access: yesFrontiers in Physiology, 2017
Numerous data show a reciprocal interaction between REM sleep and thermoregulation. During REM sleep, the function of thermoregulation appears to be impaired; from the other hand, the tonic activation of thermogenesis, such as during cold exposure ...

Solar radiation during rewarming from torpor in elephant shrews: supplementation or substitution of endogenous heat production? [PDF]

open access: yesPLoS ONE, 2015
Many small mammals bask in the sun during rewarming from heterothermy, but the implications of this behaviour for their energy balance remain little understood.

Reversal of the adipostat control of torpor during migration in hummingbirds

open access: yeseLife, 2021
Many small endotherms use torpor to reduce metabolic rate and manage daily energy balance. However, the physiological ‘rules’ that govern torpor use are unclear.

Ambient Temperature Cycles Affect Daily Torpor and Hibernation Patterns in Malagasy Tenrecs

open access: yesFrontiers in Physiology, 2020
Hibernation and daily torpor (heterothermy) allow endotherms to cope with demanding environmental conditions. The depth and duration of torpor bouts vary considerably between tropical and temperate climates, and tropical hibernators manage to cope with a

Performance of bat-derived macrophages at different temperatures

open access: yesFrontiers in Veterinary Science, 2022
Heterothermy, as a temperature-dependent physiological continuum, may affect host-pathogen interactions through modulation of immune responses. Here, we evaluated proliferation and functional performance of a macrophage cell line established from the ...

Warm bodies, cool wings: regional heterothermy in flying bats [PDF]

open access: yesBiology Letters, 2019
Many endothermic animals experience variable limb temperatures, even as they tightly regulate core temperature. The limbs are often cooler than the core at rest, but because the large locomotor muscles of the limbs produce heat during exercise, they are thought to operate at or above core temperature during activity.

Will temperature effects or phenotypic plasticity determine the thermal response of a heterothermic tropical bat to climate change? [PDF]

open access: yesPLoS ONE, 2012
The proportion of organisms exposed to warm conditions is predicted to increase during global warming. To better understand how bats might respond to climate change, we aimed to obtain the first data on how use of torpor, a crucial survival strategy of ...

Camels as a Climate‐Resilient Linchpin for Sustainable Development in Global Drylands

open access: yesSustainable Development, EarlyView.
ABSTRACT Camels represent a significant, yet underutilized, asset for advancing integrated sustainable development in the world's expanding drylands. Previous reviews have examined camels' physiology, milk composition, or pastoral systems in isolation; this review examines their potential as a climate‐resilient linchpin for food systems by synthesizing
