Outbreaks of eastern spruce budworm (Choristoneura fumiferana; hereafter SBW) are a major natural disturbance in coniferous forests of eastern North America. These outbreaks provide a superabundant source of food for insectivorous birds. Three specie

Knowledge of rangewide variation in abundance, and the processes driving such variation, may be the key to predict species tolerance to large-scale changes in climate and land use. Processes influencing population trends have been shown to vary betwe

Perceived predation risk can elicit strong behavioral responses in potential prey. During nest building, songbirds exhibit anti-predator behaviors under experimental conditions. Here, we hypothesized that females of two ground-nesting songbird specie

In northern hardwood forests, light availability is considered to be the main factor limiting seedling and sapling growth. However, field measurement of this variable is time-consuming. To address this issue, we developed random forest regression mod

Conservation efforts addressing the impacts of habitat loss and fragmentation on movements must rely on operational definitions of land-cover types that are relevant to the behavioral decisions made by the species of interest. Travel costs, and ultim

Most songbird species show some degree of fidelity to their previous breeding location, especially after successful reproduction. However, species associated with highly dynamic food sources (e.g., outbreaking insects) may have to adopt more flexible

Sustainable forest management relies on practices ensuring vigorous post-harvest regeneration. Data on regeneration structure and composition are often collected through intensive field surveys. Remote sensing technologies (e.g., Light Detection and

Context Although the spatiotemporal dynamics of spruce budworm outbreaks have been intensively studied, forecasting outbreaks remains challenging. During outbreaks, budworm-linked warblers (Tennessee, Cape May, and bay-breasted warbler) show a strong

Functional connectivity is assumed to play a critical role in population dynamics in fragmented landscapes. Although it is generally summarized as an isotropic metric, functional connectivity may be anisotropic, i.e. may vary as a function of movemen
