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

PLoS 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 ...

Primate Torpor: Regulation of Stress-activated Protein Kinases During Daily Torpor in the Gray Mouse Lemur, Microcebus murinus

Genomics, Proteomics & Bioinformatics, 2015
Very few selected species of primates are known to be capable of entering torpor. This exciting discovery means that the ability to enter a natural state of dormancy is an ancestral trait among primates and, in phylogenetic terms, is very close to the ...

Winter torpor expression varies in four bat species with differential susceptibility to white-nose syndrome

Scientific Reports, 2022
Studies examining the overwintering behaviors of North American hibernating bats are limited to a handful of species. We deployed temperature-sensitive transmitters on four species of bat that exhibit differences in their susceptibility to white nose ...

Long-term survival, temperature, and torpor patterns

Scientific Reports, 2023
Mammalian and avian torpor is highly effective in reducing energy expenditure. However, the extent of energy savings achieved and thus long-term survival appear to differ between species capable of multiday hibernation and species restricted to daily ...

Liver Transcriptome Dynamics During Hibernation Are Shaped by a Shifting Balance Between Transcription and RNA Stability

Frontiers in Physiology, 2021
Hibernators dramatically lower metabolism to save energy while fasting for months. Prolonged fasting challenges metabolic homeostasis, yet small-bodied hibernators emerge each spring ready to resume all aspects of active life, including immediate ...

Comparative transcriptomics of the Djungarian hamster hypothalamus during short photoperiod acclimation and spontaneous torpor

FEBS Open Bio, 2022
The energy‐saving strategy of Djungarian hamsters (Phodopus sungorus, Cricetidae) to overcome harsh environmental conditions comprises of behavioral, morphological, and physiological adjustments, including spontaneous daily torpor, a metabolic downstate.

The burst of electrophysiological signals in the suprachiasmatic nucleus of mouse during the arousal detected by microelectrode arrays

Frontiers in Bioengineering and Biotechnology, 2022
The neural mechanisms of torpor have essential reference significance for medical methods and long-term manned space. Changes in electrophysiology of suprachiasmatic nucleus (SCN) conduce to revealing the neural mechanisms from the torpor to arousal. Due

Survey of Factors Affecting Torpor in Lesser Hedgehog Tenrecs (Echinops telfairi)

Journal of Zoological and Botanical Gardens
Lesser hedgehog tenrecs (Echinops telfairi) are small, nocturnal insectivores from Madagascar that exhibit hibernation and brief torpor bouts. While multiple studies have investigated torpor physiology, no studies have focused on torpor in tenrecs ...

Dynamic Function and Composition Shift in Circulating Innate Immune Cells in Hibernating Garden Dormice

Frontiers in Physiology, 2021
Hibernation is characterized by successive torpor bouts during which metabolic rate is down-regulated to 2–4% of euthermic levels along with core body temperatures (Tb) ranging between 0 and 10°C.
