Data from: Linking genetic and ecological differentiation in an ungulate with a circumpolar distribution

Glenn Yannic, Joaquín Ortego, Loïc Pellissier, Nicolas Lecomte, Louis Bernatchez & Steeve D. Côté
Genetic differentiation among populations may arise from the disruption of gene flow due to local adaptation to distinct environments and/or neutral accumulation of mutations and genetic drift resulted from geographical isolation. Quantifying the role of these processes in determining the genetic structure of natural populations remains challenging. Here, we analyze the relative contribution of isolation-by-resistance (IBR), isolation-by-environment (IBE), genetic drift and historical isolation in allopatry during Pleistocene glacial cycles on shaping patterns of genetic differentiation...

Data from: Quantifying individual heterogeneity and its influence on life-history trajectories: different methods for different questions and contexts

Sandra Hamel, Jean-Michel Gaillard, Mathieu Douhard, Marco Festa-Bianchet, Fanie Pelletier & Nigel G. Yoccoz
Heterogeneity among individuals influences the life-history trajectories we observe at the population level because viability selection, selective immigration and emigration processes, and ontogeny change the proportion of individuals with specific trait values with increasing age. Here, we review the two main approaches that have been proposed to account for these processes in life-history trajectories, contrasting how they quantify ontogeny and selection, and proposing ways to overcome some of their limitations. Nearly all existing approaches to...
