Variations in oxidative stress and antioxidant defense level during different phases of hibernation in common Asian toad, Duttaphrynus melanostictus

open access: yesBiology Open, 2021
To assess redox status during hibernation with metabolic depression, oxidative stress parameters and antioxidant defense were assessed during different phases of hibernation including active period, hibernation, arousal, and post-arousal period, in the ...

Physiochemical and histological study on the effect of the hibernation on the liver of Uromastyx acanthinura (Bell, 1825).

open access: yesمجلة المختار للعلوم, 2013
This study described the changes in the liver of Uromastyx acanthinura (Bell, 1825) males and females during hibernation and activity seasons. The results revealed that, hibernation causes increase fatty liver and pigment cells with abundant damage ...

Optimal hibernation theory

open access: yes, 2020
© 2019 The Mammal Society and John Wiley & Sons Ltd Hibernation has received considerable attention from physiologists and natural historians, but theoretical and ecological treatments of hibernation are rarer.

Hibernation in the Alligator

open access: yesExperimental Biology and Medicine, 1952
SummaryAlthough alligators are quite active in the winter if the temperature is high they have a pronounced hypoglycemia and no appetite. There is no seasonal change in metabolic rate in either the alligator or caiman. The caiman does not hibernate. Pituitary powder produces prolonged hyperglycemia and increases the metabolic rate.

Hibernation Sites and Activity of Bats During Winter

open access: yes, 2023
In the temperate region, bats have evolved the strategy of hibernation to survive the harsh winter. During hibernation, bats enter the vulnerable state of torpor that requires specific environmental conditions to function optimally. Bats are known to use

Over-Winter Survival and Nest Site Selection of the West-European Hedgehog (Erinaceus europaeus) in Arable Dominated Landscapes

open access: yesAnimals, 2020
The West-European hedgehog (Erinaceus europaeus) has declined markedly in the UK. The winter hibernation period may make hedgehogs vulnerable to anthropogenic habitat and climate changes.

HIBERNATION OF COLEOPTERA [PDF]

open access: yesThe Canadian Entomologist, 1885
The condition in which Coleoptera pass the winter is a subject on which there are in American literature but few recorded observations. That no species hibernates in the egg stage is highly probable, though in all the others it occurs—some wintering in the perfect state alone, some in the larva and the imago condition, and others as larva and pupa.Many

Types of Mammalian Hibernation [PDF]

open access: yes, 1956
Mammalian hibernation is characterized by a reduction in metabolic activities and an increase in scrum magnesium (1). Although these similarities exist, there are also striking differences in the patterns of hibernation among mammalian types.

A Unique Energy-Saving Strategy during Hibernation Revealed by Multi-Omics Analysis in the Chinese Alligator

open access: yesiScience, 2020
Summary: Many ectotherms hibernate in face of the harsh winter conditions to improve their survival rate. However, the molecular mechanism underlying this process remains unclear.
