Increased brain histamine H₃ receptor expression during hibernation in golden-mantled ground squirrels

BMC Neuroscience, 2003
Background Hibernation is a state of extremely reduced physiological functions and a deep depression of CNS activity. We have previously shown that the histamine levels increase in the brain during hibernation, as does the ratio between histamine and its

Hibernation with Rhythmicity in the Retina, Brain, and Plasma but Not in the Liver of Hibernating Giant Spiny Frogs (Quasipaa spinosa)

Biology, 2022
Hibernation in ectotherms is well known, however, it is unclear how the circadian clock regulates endocrine and antioxidative defense systems of aquatic hibernators.

Reproductive stages in lowbush blueberry (Vaccinium angustifolium) occur earlier with increasing temperature

American Journal of Botany, EarlyView.
Abstract Premise Climate change is altering the timing of many plant phenological events, yet most studies focus on flowering, with less attention given to later reproductive stages such as fruit development and ripening. Vaccinium angustifolium (lowbush blueberry) is an important perennial berry species that may be sensitive to these changes.

HIBERNATION, A MODEL OF NEUROPROTECTION [PDF]

TheScientificWorldJOURNAL, 2001
Hibernation, a natural model of tolerance to cerebral ischemia, represents a state of pronounced fluctuation in cerebral blood flow where no brain damage occurs. Numerous neuroprotective aspects may contribute in concert to such tolerance. The purpose of this study was to determine whether hibernating brain tissue is tolerant to penetrating brain ...

Flight of the dragons: a global review of migration in Odonata

Biological Reviews, EarlyView.
ABSTRACT Insects are the most abundant and ecologically important animal migrants. Yet, we know relatively little about the patterns and processes underlying insect migration. Dragonflies (Anisoptera) and damselflies (Zygoptera) comprise the ancient insect order Odonata, whose ancestors were the first organisms to fly on Earth.

Application of artificial hibernation technology in acute brain injury

Neural Regeneration Research
Controlling intracranial pressure, nerve cell regeneration, and microenvironment regulation are the key issues in reducing mortality and disability in acute brain injury. There is currently a lack of effective treatment methods.

Hibernation in Reeves’ Turtles (Mauremys reevesii) in Qichun County, Hubei Province, China: Hibernation Beginning and End and Habitat Selection

Animals, 2022
Hibernation protects turtles from extreme winter conditions. Reeves’ turtle (Mauremys reevesii) is a medium-sized aquatic turtle that lives in freshwater habitats in lowland areas with still or slowly moving water.

Creativity and its link to epilepsy

Epilepsia Open, EarlyView.
Abstract Creative thinking represents one of our highest‐order cognitive processes, involving multiple cortical structures and an intricate interplay between several cortical and subcortical networks. It results in novel ideas that translate to useful products or concepts. The evolutionary purpose of creativity is therefore apparent, as it advances our

Defining the pollinator garden: is conceptual flexibility a feature or a bug?

Frontiers in Ecology and the Environment, EarlyView.
Ecologists often aim to reduce conceptual ambiguity by attempting to create rigid shared lexicons. These efforts imply that ambiguity is undesirable. In some contexts, however, conceptual flexibility comes with under‐discussed benefits. Here, we use the lens of pollinator gardening to explore how conceptual flexibility is built into participatory ...

Serum immune-related proteins are differentially expressed during hibernation in the American black bear. [PDF]

PLoS ONE, 2013
Hibernation is an adaptation to conserve energy in the face of extreme environmental conditions and low food availability that has risen in several animal phyla.
