Abstract Although most predators usually avoid human activity, some individuals instead will habituate to it. Habituation to human presence and infrastructure by predator species such as wolves may lead to conflicts implicating serious risks for public safety and for the survival of the animals involved. Accordingly, this research project aims to shed light on the relationship between wolves and recreational structures using telemetry data from 10 wolves located in the Parc National du Mont-Tremblant (Québec, Canada) and its surrounding area. Using resource selection functions (RSFs), we observed wolf habitat selection in relation to these structures during three biological periods (denning: May–June; rendezvous: June–October; and nomadic: October–April). Our results revealed that wolves selected proximity to linear structures (roads and trails) during the denning and rendezvous periods, but this selection depended on the density of such structures in the surroundings (i.e., functional response in habitat selection): wolves selected proximity to linear structures when these structures were present at greater densities. Wolves avoided housing structures (campsites, cabins, park facilities), especially when these structures were present at greater densities, suggesting that wolves perceived them as a risk. These results suggest that conflicts between visitors and wolves were unlikely to occur in campgrounds during the time of our study. This could indicate that the management measures implemented by the park following the past episodes of conflict were effective. However, wolves’ use of linear structures could lead to increased tolerance to human proximity if left unmanaged.

After decades of persecution, large carnivores are returning to human-occupied landscapes in many areas of North America and Europe. To ensure the safety of both people and wildlife, we need to understand how these animals perceive and select habitat as they navigate through developed area. Here, I investigate habitat selection by wolves and cougars in a 20,000 km2 landscape characterized by a marked gradient of urban and industrial development. I used data from over 15,000 km of wolf and cougar movement pathways, and from over 750 kill sites made by these two predators. These data were collected during the past 22 winters in Banff National Park (Alberta, Canada) and environs. Using GIS software, I created habitat selection models by comparing ‘used’ resources (e.g., topography, habitat type) found along movement pathways and at kill sites, with random points located <500 m from used sites. I then incorporated the results of these habitat selection models into a connectivity analysis to quantify the predicted flow of both movement and predation across the landscape. These results illustrate the extent to which ‘connectivity’ depends on species (e.g., cougars vs. wolves), behavior (movement vs. foraging), and proximity to people. These results are being used to inform policy on land-use planning in areas where large carnivores and people co-exist.

Abstract Fretwell and Lucas's (1970) model relating settling patterns and habitat suitability was tested by examining the distribution among habitats of male Red-winged Blackbirds (Agelaius phoeniceus) at relatively low (26 males/km2 in 1978)a nd high (45 males/km2 in 1979)overall population densities. Wetlands and hayfields were identified as the most suitable breeding habitats on the basis of habitat selection patterns of territorial males and other evidence, whereas forest, cropland, and human-occupied areas generally were avoided. Some "packing" of males into hayfields occurred when population level increased, but the greatest changes were recorded from less suitable habitats. Occupancy of wetlands and hayfields remained relatively stable. These results were in general accordance with predictions from Fretwell and Lucas's model, but their model did not account for some aspects of spacing behavior. This is because habitat imprinting, site fidelity, and chance events, in addition to territorial behavior, likely contributed also to the spacing patterns of male Red-winged Blackbirds observed.
