Abstract: The ability to differentiate among conspecifics on the basis of genetic relatedness can be advantageous in kin and mate selection. Selection of mates that are of an intermediate degree of relatedness maximizes the propagation of…

Abstract: Understanding how species have responded to strong climatic fluctuations accompanying glacial-interglacial cycles is critical to predicting their likely responses to future climate change, and therefore can help guide conservation strategies. Using molecular phylogeography and ecological…

DOI: 10.1016/j.cbpa.2017.04.004
Abstract: Stable carbon isotope ratios (δ13C) in breath show promise as an indicator of immediate metabolic fuel utilization in animals because tissue lipids have a lower δ13C value than carbohydrates and proteins. Metabolic fuel consumption is…

DOI: 10.1016/j.ijpara.2020.12.001
Abstract: Understanding why some individuals are more prone to carry parasites and spread diseases than others is a key question in biology. Although epidemiologists and disease ecologists increasingly recognize that individuals of the same species can…

Abstract: The sequence diversity of microRNAs (miRNAs) allows these potent regulators of mRNA fate to bind multiple transcripts, giving them the power to inhibit diverse cellular processes. Therefore, miRNAs may regulate metabolic rate suppression (also termed…

Abstract: The dynamic relationship between glucocorticoids and behavior are not well understood in wild mammals. We investigated how weather, body condition, and reproduction interact to affect cortisol levels and activity patterns in a free-living population of…

Abstract: Energy balance and thermoregulation in many fat-storing seasonal hibernators show a circannual rhythm. To understand the physiological mechanisms of the seasonal pre-hibernation fattening related to the regulation of energy expenditure and thermogenesis, we cold-exposed fattening…

Abstract: Mammals entering hibernation undergo drastic reductions in metabolic rate and body temperature (Tb; to as low as ∼2% of euthermic metabolic rate and 1°C to −2°C). Although ventilation (V˙E) is also greatly reduced in hibernating…
