Vertical photographs of the calving grounds have been used since 1984 to estimate the caribou (Rangifer tarandus) population of the Rivière George Caribou Herd (RGCH) in Northern Québec and Labrador. In spite of large confidence intervals, the 1984

Le roseau commun exotique (Phragmites australis [Cav.] Trin. ex Steud. subsp. australis) s’est propagé graduellement au cours des 20 dernières années dans la réserve naturelle du Marais-Léon-Provancher, un site de 125 ha avec 19 ha de marais d

Ecological theory predicts that the intensity of antipredator responses is dependent upon the spatiotemporal context of predation risk (the risk allocation hypothesis). However, most studies to date have been conducted over small spatial extents, and

Habitat connectivity influences the distribution dynamics of animals. Connectivity can therefore shape trophic interactions, but little empirical evidence is available, especially for large mammals. In forest ecosystems, logging alters functional con

Summary Habitat selection strategies translate into movement tactics, which reckon with the predator–prey spatial game. Strategic habitat selection analysis can therefore illuminate behavioural games. Cover types at potential encounter sites (i.e.

The impact of anthropogenic disturbance on the fitness of prey should depend on the relative effect of human activities on different trophic levels. This verification remains rare, however, especially for large animals. We investigated the functional

Species interactions within food webs are driven by multiple constraints, including those imposed by seasonal changes in the environment. Ecologically sound definitions of seasons may therefore be a prerequisite for clarifying predator prey interacti

We assessed habitat selection of moose in a study area containing 2 highways and a network of forest roads in Quebec, Canada. We tested the hypothesis that roadways would affect moose habitat selection and that moose behaviour would vary with time, p

Efforts in isolating the relative effects of resources and disturbances on animal-distribution patterns remain hindered by the difficulty of accounting for multiple scales of resource selection by animals with seasonally dynamic drivers. We developed

Logging negatively affects the threatened forest-dwelling caribou (Rangifer tarandus caribou ) through its positive effects on large predator populations. As recruitment is a key component of caribou population growth rate, we assessed calving rates
