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: Linking songbird nest predation to seedling density: sugar maple masting as a resource pulse in a forest food web

Marie-Line Fiola, Alizée Vernouillet & Marc-André Villard
The ecological literature presents considerable evidence for top-down forcing on the maintenance of species diversity. Yet, in temperate forests, bottom-up forces often exert a strong influence on ecosystem functioning. Here, we report on the indirect influence of a pulsed resource, sugar maple (Acer saccharum) seed production, on nest survival in a migratory songbird. We hypothesized that seed production in year t would determine daily nest survival rate in year t + 1 through its effects...
