Physiological dynamics of body temperature and heart rate during hibernation periods in male Japanese black bears (Ursus thibetanus japonicus) [PDF]

PeerJ
Background The Japanese black bear (Ursus thibetanus japonicus) exhibits a profound seasonal metabolism shift, with a substantial increase in body weight in autumn and metabolic suppression during hibernation in winter.

Assessing the Hibernation Ecology of the Endangered Amphibian, Pelophylax chosenicus Using PIT Tagging Method [PDF]

Animals
The Gold-spotted pond frog (Pelophylax chosenicus (Okada, 1931)), classified as an endangered species in South Korea, has experienced significant population declines due to habitat loss, primarily driven by agricultural expansion and urbanization.

Dynamics in gut microbiota diversity, composition, and assembly reveal the adaptability of invasive snail Pomacea canaliculata during hibernation in rice fields [PDF]

Frontiers in Microbiology
The gut microbiota plays a crucial role in host immunity and metabolism and may facilitate the adaptation of invasive species to new environments. During hibernation, gut microbial communities undergo compositional shifts to help hosts cope with low ...

Hibernation induced biochemical changes in spotted stem borer Chilo partellus

The Indian Journal of Agricultural Sciences, 2023
Spotted stem borer, Chilo partellus (Swinhoe) is one of the most destructive pests of sorghum and maize, and undergoes hibernation during harsh winters.

Microbial gene expression during hibernation in arctic ground squirrels: greater differences across gut sections than in response to pre-hibernation dietary protein content

Frontiers in Genetics, 2023
Obligate seasonal hibernators fast for 5–9 months depending on species yet resist muscle atrophy and emerge with little lean mass loss. The role of the gut microbiome in host nitrogen metabolism during hibernation is therefore of considerable interest ...

Downregulation of cyclic adenosine monophosphate levels in leukocytes of hibernating captive black bears is similar to reported cyclic adenosine monophosphate findings in major depressive disorder

Frontiers in Psychiatry, 2023
IntroductionCyclic adenosine monophosphate (cAMP) levels in the lymphoblasts and leukocytes of patients with major depressive disorder (MDD) have been reported to be downregulated compared to in controls.

Breeding and hibernation of captive meadow jumping mice (Zapus hudsonius).

PLoS ONE, 2021
Hibernating mammals exhibit unique metabolic and physiological phenotypes that have potential applications in medicine or spaceflight, yet our understanding of the genetic basis and molecular mechanisms of hibernation is limited. The meadow jumping mouse,

Decreases in body temperature and body mass constitute pre-hibernation remodelling in the Syrian golden hamster, a facultative mammalian hibernator [PDF]

Royal Society Open Science, 2016
Hibernation is an adaptive strategy for surviving during periods with little or no food availability, by profoundly reducing the metabolic rate and the core body temperature (Tb). Obligate hibernators (e.g.

Long-term individualized monitoring of sympatric bat species reveals distinct species- and demographic differences in hibernation phenology

BMC Ecology and Evolution, 2022
Background Hibernation allows species to conserve energy and thereby bridge unfavorable environmental conditions. At the same time, hibernation imposes substantial ecological and physiological costs.

Temporal dynamics of the bat wing transcriptome: Insight into gene-expression changes that enable protection against pathogen

Virulence, 2023
Skin acts as a mechanical barrier between the body and its surrounding environment and plays an important role in resistance to pathogens. However, we still know little regarding skin responses to physiological changes, particularly with regard to ...
