Can't outrun recurrence: Long‐term outcomes of treating American black bear sarcoptic mange

The Journal of Wildlife Management, EarlyView.
Abstract The growing incidence of sarcoptic mange in American black bears (Ursus americanus) has become a concern for wildlife managers in the eastern United States. Inconsistency in the use of single and multi‐dose treatment approaches makes it difficult to evaluate their effects on post‐release outcomes of mange‐rehabilitated bears, which remain ...

Periodic expression of Per1 gene is restored in chipmunk liver during interbout arousal in mammalian hibernation

Scientific Reports
Circadian rhythms play an important role in many physiological processes. We have previously reported that no periodic fluctuation in the Bmal1 mRNA is observed in the liver of the chipmunk, a mammalian hibernator, in the hibernation season, suggesting ...

Short-Term Estivation and Hibernation Induce Changes in the Blood and Circulating Hemocytes of the Apple Snail Pomacea canaliculata

Metabolites, 2023
States of natural dormancy include estivation and hibernation. Ampullariids are exemplary because they undergo estivation when deprived of water or hibernation when exposed to very low temperatures.

Effects of off‐highway vehicle activity on Arizona wildlife: a systematic literature review

The Journal of Wildlife Management, EarlyView.
The published literature indicates that off‐highway vehicles (OHVs) predominantly negatively affect native Arizona amphibians, mammals, and reptiles, while effects of OHVs on native Arizona birds are mostly unknown or neutral. Abstract Off‐highway vehicle (OHV) recreation has dramatically increased in Arizona, USA, prompting concerns about potential ...

Historical data reveal earlier flowering under environmental change

Nordic Journal of Botany, EarlyView.
Global temperatures have risen ~ 1.1°C since the 1800s and the mean annual air temperature in the Arctic has increased by nearly four times the global average. Temperature has a significant effect on fundamental life‐cycle events of flora and fauna. With temperatures increasing, Arctic plants are expected to shift their active periods accordingly, with

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 ...

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 ...

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

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.

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

Journal of Field Robotics, EarlyView.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full
