Wildlife Biology, EarlyView.The consumption of human food subsidies influences ecological processes, and can affect individual behavior and fitness with population level changes in abundance and distribution. American black bears Ursus americanus often consume human food subsidies, which have been correlated with increased bear body size, age‐specific fertility and mortality ...

Expressions of TLR4, MyD88, IRAK4 and NF-κΒ in the oviduct of Chinese brown frog (Rana dybowskii)
European Journal of Histochemistry, 2019 One special physiological phenomenon of the Chinese brown frog (Rana dybowskii) is that its oviduct goes through expansion prior to pre-hibernation instead of expanding during the breeding period. Our previous study discovered that some cytokines such as

Quantification of human‐caused mortality in an imperiled turtle
Wildlife Biology, EarlyView.For many threatened and endangered species, the importance of human‐caused mortality relative to other sources has not been quantified, making it difficult to assess the effectiveness of mortality‐reduction strategies. We used radio telemetry data, pooled across studies at protected sites in the US states of Illinois and Wisconsin, to estimate natural ...

Conserving energy during hibernation
, 2017 How hibernators manage to reduce their high metabolic rate - and therefore energy expenditure - from times when they are active to small almost immeasurable fractions during hibernation has attracted scientific inquiry for over a century.

Wildlife Letters, EarlyView.Asiatic black bears in Russia face conservation threats such as habitat destruction and fragmentation, which exacerbate food shortages caused by crop failures. This study explores an innovative approach to rehabilitating bears that abandon hibernation in mid‐winter due to extreme exhaustion by providing supplemental food near their den sites.

Types of Mammalian Hibernation
, 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.

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)

Comparison of data handling techniques for modeling bat acoustic activity
Wildlife Society Bulletin, EarlyView.We deployed 169 acoustic recording units (A) across the Raystown Lake Project, Huntingdon County, Pennsylvania, USA (B). Echolocation recordings were used to evaluate alternative acoustic data handling methods and their effects on bat acoustic activity model predictions.

AnimalsThe gut microbiota plays a crucial role in the host’s metabolic processes. Many studies have shown significant changes in the gut microbiota of mammals during hibernation to adapt to the changes in the external environment, but there is limited research ...
