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.

A lagging recovery: the delayed restoration of gut microbial diversity in Rhinolophus sinicus post-hibernation [PDF]

Animal Microbiome
Background Hibernation enables animals to survive extreme environments, yet gut microbiome dynamics across the full hibernation cycle remain poorly understood, particularly in chiropterans with unique physiological traits.

A family of ribosome hibernation factors widespread in Archaea [PDF]

Nature Communications
Ribosome hibernation preserves translation machinery during stress, yet its mechanisms in Archaea remain poorly defined. Using cryo-EM analysis, we studied hibernation pathways in Pyrococcus abyssi stressed cells.

A family of archaeal hibernation factors that bind in tandem and protect ribosomes in dormant cells [PDF]

Nature Communications
Under nutrient limitation or stress, ribosome hibernation factors inactivate and protect ribosomes. Although ribosome hibernation plays an important role in microbes, we lack a complete understanding of this process in archaea. Here, we identify a family

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,
