Monitoring rodents' life history by body temperature and activity

Wildlife Biology, EarlyView.
European hamster populations are rapidly declining all over their distribution area. One of the suggested reasons is a strong and ongoing decrease in the reproductive output of about 77% since the nineteen twenties. The cause of this decline is, however, unknown.

Blubber Thickening Driven by UCP1 Inactivation: Insights from a Cetacean‐Like Transgenic Mouse Model

Integrative Zoology, EarlyView.
UCP1 inactivation of cetaceans in mice drives BAT whitening and iWAT hyperplasia, promoting fat accumulation for aquatic adaptation. Abstract Cetaceans possess thick blubber, a specialized adipose tissue essential for thermal insulation, a streamlined body form, energy storage, and buoyancy. However, the mechanisms that underpin this adaptation are not

Genomic Investigations Unveil the Genetic Underpinnings of Environmental Adaptation in African Goat Populations

Integrative Zoology, EarlyView.
This study integrates genomics and landscape genetics to analyze African goat environmental adaptation. Analyzing 1591 samples, it finds population structure differentiates geographically into four groups, with gene flow between wild Yura goats and North Africans.

The impact of thermogenesis on the origin of insect pollination

Thermogenesis in plants is the ability to raise their temperature above that of the surrounding air through metabolic processes, and is especially detected in reproductive organs.

Gut Microbiota of Gray Snub‐Nosed Monkeys: Adaptation to Seasonal Variations Through Energy Compensation and Thermogenesis

Integrative Zoology, EarlyView.
Based on metagenome‐assembled genomes (MAGs), the gut microbiota of the gray snub‐nosed monkeys recovered 1229 non‐redundant MAGs. The gut microbiota showed an enhanced capacity to produce energy substrates with increased conversion activity of these substrates during winter.

Murburn scheme for mitochondrial thermogenesis [PDF]

, 2018
The physiology of thermogenesis in mitochondria (mediated by uncoupling protein, UCP) has traditionally been explained as the dissipation of proton gradient across the inner mitochondrial membrane into heat.

Comparative Genomics and Functional Evidence for Convergent Adaptation to Hypoxia in Mammals

Integrative Zoology, EarlyView.
This study reveals convergent selection in mammals adapted to hypoxia. Functional assays demonstrate that amino acid mutations reduce oxidative stress, attenuate hypoxia‐induced injury, and modulate the hypoxia‐inducible transcription factor (HIF)‐driven hypoxic response.

Seasonal Dynamics of Community and Function of Gut Microbiome in Taihangshan Macaque (Macaca mulatta tcheliensis): Inferred From Metagenomic Data

Integrative Zoology, EarlyView.
A total of 435 non‐redundant metagenome‐assembled genomes (MAGs) were obtained from fecal samples of Taihangshan macaque across all four seasons. The alpha diversity of the gut microbiome in spring and winter was significantly higher than in summer and autumn. Furthermore, marked differences were detected in functional pathways and carbohydrate enzymes

Orexin modulates brown adipose tissue thermogenesis

Biomolecular Concepts, 2012
Non-shivering thermogenesis in brown adipose tissue (BAT) plays an important role in thermoregulation. In addition, activations of BAT have important implications for energy homeostasis due to the metabolic consumption of energy reserves entailed in the ...
