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

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.

Optimal body mass-length ratio during hibernation for Emys orbicularis (Linnaeus, 1758) – European Pond Turtle

Heliyon, 2021
The aim of this study was to determine optimal body mass/length ratios of Emys orbicularis before hibernation. We obtained 213 measurements of wild-caught and captive-bred turtles during 9 years (2011–2019) and determined regression curves that show ...

What enables hibernation? : insights from a mammalian hibernator, Syrian hamster [PDF]

, 2018
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). Mammalian hibernators store fat extensively in white adipose tissues (WATs)

Road mortality alters the body size and age structure of amphibians

Oikos, EarlyView.
Road mortality affects a wide range of animal species, including amphibians. Worldwide, many amphibian species, including the Asiatic toad Bufo gargarizans, are impacted by road mortality, but the ecological consequences remain poorly understood. This study aimed to evaluate how road mortality influences population traits by comparing body sizes and ...

Differential AMPK-mediated metabolic regulation observed in hibernation-style polymorphisms in Siberian chipmunks

Frontiers in Physiology, 2023
Hibernation is a unique physiological phenomenon allowing extreme hypothermia in endothermic mammals. Hypometabolism and hypothermia tolerance in hibernating animals have been investigated with particular interest; recently, studies of cultured cells and

Comments on : diet, physiology and ecology of fossil mammals as inferred from stable carbon and nitrogen isotope biogeochemistry: implications for Pleistocene bears [PDF]

, 1997
A detailed study of isotopic relationships in European Pleistocene ursid teeth have been presented by Bocherens et al. (1994). We agree with the resu1ts and broad conclusions derived from the stable carbon isotope relationships.

Community composition, abundance and activity‐density of carabids and staphylinids depend on prey abundance and adjacent habitat even in diverse agricultural landscapes

Pest Management Science, EarlyView.
Carabid and staphylinid communities are shaped by adjacent habitat type, prey availability and landscape context, influencing natural pest control across agricultural landscapes. Abstract BACKGROUND The functioning of agroecosystems depends on key ecosystem processes that deliver ecosystem services, yet agricultural management has increasingly shifted ...

Dietary Lipids Affect the Onset of Hibernation in the Garden Dormouse (Eliomys quercinus): Implications for Cardiac Function

Frontiers in Physiology, 2018
Dietary lipids strongly influence patterns of hibernation in heterotherms. Increased dietary uptake of n-6 polyunsaturated fatty acids (PUFAs), particularly of linoleic acid (LA, C18:2 n-6), enables animals to reach lower body temperatures (Tb ...

The European honey buzzard (Pernis apivorus) as an ally for the control of the invasive yellow‐legged hornet (Vespa velutina nigrithorax)

Pest Management Science, Volume 81, Issue 4, Page 2237-2247, April 2025.
The predatory effect of the honey‐buzzard affects the reproductive performance of Asian‐hornet colonies, decreasing the density of workers over distance and time. The foraging distances of the honey‐buzzard concentrates within the first 2000 m from nest, which supports the results observed.

What is winter? Modeling spatial variation in bat host traits and hibernation and their implications for overwintering energetics

Ecology and Evolution, 2021
White‐nose syndrome (WNS) has decimated hibernating bat populations across eastern and central North America for over a decade. Disease severity is driven by the interaction between bat characteristics, the cold‐loving fungal agent, and the hibernation ...
