Available in PDF, EPUB and Kindle. Book excerpt: Focusing on the physiological and behavioral factors that enable a species to live in a harsh seasonal environment, this book places the social biology of marmots in an environmental context. It draws on the results of a forty-year empirical study of the population biology of the yellow-bellied marmot near the Rocky Mountain Biological Laboratory in the Upper East River Valley in Colorado, USA. The text examines life-history features such as body-size, habitat use, environmental physiology, social dynamics, and kinship. Considerable new data analyses are integrated with material published over a fifty-year period, including extensive natural history observations, providing an essential foundation for integrating social and population processes. Finally, the results of research into the yellow-bellied marmot are related to major ecological and evolutionary theories, especially inclusive fitness and population regulation, making this a valuable resource for students and researchers in animal behavior, behavioral ecology, evolutionary biology, ecology and conservation.

This book was released on 2015 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: Individuals vary phenotypically. Phenotypic variation can emerge because of bet-hedging, micro-evolutionary responses, and because of phenotypic plasticity, an important mechanism by which individuals can cope with environmental change. Phenotypic plasticity, the ability of an individual to respond to environmental variation, can influence demographic parameters (e.g., birth and death rates) that influence population dynamics. I used a population of yellow-bellied marmots (Marmota flaviventris) as a study system to explore the effect of individual variation due to phenotypically plastic responses on population dynamics. First, I used linear mixed effects models to examine and quantify the plastic responses in a set of morphological, life-history and social traits in response to climatic and social variation. Results showed that individuals have the ability to respond to environmental variation by expressing different phenotypes, and that individuals differ in the nature of their plastic responses. Second, I developed an Integral Projection Model to evaluate the trait-mediated response to environmental variation. Results indicated that variation in survival and reproduction are the main drivers of fluctuation in the population growth rate, and that winter temperature, but not spring temperature and bare ground date, are important environmental drivers of population fluctuations. Furthermore, although variation in a key morphological trait, body mass, does not explain significant variation in population growth rate, it plays an important role in mediating the individuals' response to the environment. Finally, I developed an Individual Based Model, to incorporate individual differences in the rate at which animals gained mass seasonally, and evaluated the effect of such individual heterogeneity for population persistence. Results indicated that the proportion of individuals in the population that engaged in compensatory growth influenced population dynamics, and the cost of expressing such compensatory responses had a strong effect on population dynamics. If growth rate plasticity varies among-individuals, the population can afford the cost of plasticity; otherwise, plasticity increases the time to population extinction. These findings emphasize the importance of phenotypic plasticity as a mechanism shaping individual variation in a population, and as an important response of a species' adaptation to environmental change.
