DOI: 10.1007/s00265-017-2410-5
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… read more here.

Lovers, not fighters: docility influences reproductive fitness, but not survival, in male Cape ground squirrels, Xerus inauris
Sign Up to like & getrecommendations! Published in 2024 at "Behavioral Ecology and Sociobiology"
DOI: 10.1007/s00265-023-03421-8
Abstract: Over their lifetime, individuals may use different behavioural strategies to maximize their fitness. Some behavioural traits may be consistent among individuals over time (i.e., ‘personality’ traits) resulting in an individual behavioural phenotype with different associated… read more here.

DOI: 10.1007/s10164-024-00832-6
Abstract: Dietary flexibility allows animals to respond adaptively to food pulses in the environment. Here we document the novel emergence of widespread hunting of California voles and carnivorous feeding behavior by California ground squirrels. Over two… read more here.

DOI: 10.1007/s13364-017-0347-8
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… read more here.

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… read more here.

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… read more here.

DOI: 10.1016/j.ygeno.2021.01.017
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… read more here.

DOI: 10.1016/j.yhbeh.2020.104818
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… read more here.

DOI: 10.1016/j.zool.2020.125834
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… read more here.

DOI: 10.1038/s41467-024-49996-2
Abstract: Mammalian hibernators survive prolonged periods of cold and resource scarcity by temporarily modulating normal physiological functions, but the mechanisms underlying these adaptations are poorly understood. The hibernation cycle of thirteen-lined ground squirrels (Ictidomys tridecemlineatus) lasts… read more here.
