Variation in hibernation patterns of a temperate zone mammal [PDF]
Temperate-zone species frequently employ hibernation as a winter energy-saving strategy to overcome periods with unfavourable ambient conditions and low food availability.

Integrative Zoology, EarlyView.High altitudes are challenging for the animals that inhabit these environments. The Xizang plateau frog (Nanorana parkeri) survives in high‐altitude environments through a synergistic strategy of metabolic remodeling and protein expression adjustment to optimize energy efficiency and enhance cellular protection.

Testosterone influences hibernation in golden-mantled ground squirrels
, 1990 At different phases of the hibernation season, castrated male golden-mantled ground squirrels were implanted with capsules that either were filled with testosterone (T) or left empty (blank).

The Wonder Years: A Demographic Approach to Revisit the Age‐at‐Size Conundrum in Amphibians
Integrative Zoology, EarlyView.We combined repeated body size measurements of marked individuals of unknown age throughout their adult life with growth records of individuals marked as postmetamorphic juveniles and recaptured years later as sexually mature adults, focusing on 10 amphibian species in central Spain.

Nail growth arrest under low body temperature during hibernation
Journal of Physiological SciencesGrowth and differentiation are reduced or stopped during hibernation, an energy conserving strategy in harsh seasons by lowered metabolism and body temperature. However, few studies evaluated this in a same individual using a non-invasive method. In this

Harmonic radar tracking reveals random dispersal pattern of bumblebee (Bombus terrestris) queens after hibernation [PDF]
, 2019 The dispersal of animals from their birth place has profound effects on the immediate survival and longer-term persistence of populations. Molecular studies have estimated that bumblebee colonies can be established many kilometers from their queens ...

Warm Spring Weather Alters Calling Phenology of Four Sympatric Early‐Breeding Anurans
Integrative Zoology, EarlyView.An unusually warm March in 2024 (“false spring”) followed by freezing temperatures allowed us to assess the impact of a weather event on an amphibian community. The calling activity of all four species was associated with increasing temperature, and the first date of calling was advanced by 11–18 days.

Animals at the extremes: hibernation and torpor
, 2010 Hibernation is an ingenious adaptation that some animals employ to survive difficult conditions in winter. This unit examines the differences between hibernation and torpor, and discusses the characteristic signs of hibernation behaviour. It explores the

Agricultural and Forest Entomology, EarlyView.Global climate change will modify the distribution areas of important cereal bugs by changing environmental conditions. Information on their dispersal possibilities can help to clarify their future economic importance and damage potential. In this study, we modelled the current potential and future distribution of four important pests by using the ...

Drivers of bat researchers’ intent to adopt field hygiene practices
Conservation Biology, EarlyView.Abstract Infectious disease is a growing threat to wildlife, with zoonotic transmission most likely at the human–wildlife interface. One underappreciated activity at this interface is fieldwork with wild animals, but associated risks can be mitigated through field hygiene (FH) practices, such as using personal protective equipment and other appropriate
