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.

Liver transcriptome analysis reveals the molecular response to hibernation challenge in the Chinese soft-shelled turtle (Pelodiscus sinensis)

Frontiers in Marine Science
Hibernation is a physiological strategy animals use to survive in hostile environments with extreme temperature challenges and food scarcity. During this state, significant changes occur in metabolism and cellular function, with numerous stress response ...

Immunoreactivities of PPARγ2, leptin and leptin receptor in oviduct of Chinese brown frog during breeding period and pre-hibernation

European Journal of Histochemistry, 2014
The Chinese brown frog (Rana dybowskii) is a special amphibian with one unique physiological phenomenon, which is that its oviduct expands prior to hibernation, instead of during the breeding period.

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)

Geographical Variation in Thermal Adaptation of the Asiatic Toad (Bufo gargarizans)

Integrative Zoology, EarlyView.
Northern and southern populations of Bufo gargarizans exhibit coordinated divergence in thermal preference, resting metabolic rate, and TRPM4 temperature sensitivity along a climatic gradient. ABSTRACT Thermal adaptation in animals can manifest in multiple dimensions, yet few studies have integrated behavioral, physiological, and molecular perspectives

Gut Microbiome Functional Reprogramming Reflects Divergent Social Strategies in a Wild Primate

Integrative Zoology, EarlyView.
Wild golden snub‐nosed monkeys employ divergent social strategies, forming reproductive one‐male units and bachelor all‐male units. We reveal that these social structures, intertwined with seasonal diets, drive distinct functional reprogramming in their gut microbiomes. This adaptive microbial plasticity plays a crucial role in primate socio‐ecological

The effect of hibernation on the morphological structure and expression of creatine kinase in the intestine of Pelodiscus sinensis

Aquaculture Reports
The intestinal function of hibernating animals undergoes seasonal changes, during which they are in a fasting state, which also affects the morphology, structure, and function of intestine.

Physiological criticality in hibernation dynamics

, 2019
Hibernation has been selected for increasing survival in harsh climatic environments. Seasonal variability in temperature may push body temperature of hibernating animals across boundaries of alternative states between euthermic temperature and torpor ...

Fat‐Containing Soft Tissue Lesions of the Limbs and Body Wall—A Pictorial Essay

Journal of Medical Imaging and Radiation Oncology, EarlyView.
ABSTRACT Lipomatous tumours are frequently encountered on imaging. The spectrum of lipomatous tumours ranges from simple lipomas, which can be monitored clinically, to high‐grade liposarcomas, which require timely, multidisciplinary management. The presence of fat within lesions may also be observed in non‐lipomatous tumours, as well as in a variety of
