Abstract

Anthropogenic linear features often alter wildlife behaviour and movement. Landscape features, such as habitat, can have important mediating effects on wildlife response to disturbance and yet are rarely explicitly considered in how habitat and disturbance interact. We tested the movement and space-use responses of GPS-collared wolves to linear features with respect to adjacent habitat variation. We simultaneously modeled wolf movement and selection within a conditional logistic regression framework (integrated Step Selection Analysis). We explicitly considered how adjacent habitat alters these responses through putative effects such as movement friction. Classifying linear features based on the selection and movement response of wolves revealed that pairing transmission lines and primary roads increased the avoidance response to be greater than either feature on their own and provided evidence of a semi-permeable barrier to movement. In contrast, features with reduced human activity, including secondary and tertiary roads were highly selected for and function as movement corridors.

Synthesis and applications: Explicitly parameterizing adjacent habitats provides evidence that where a linear feature is routed and which habitats it interacts with will have the greatest implications for wolf behavioural responses. Reduced avoidance behaviour in highly risky environments signifies the importance of habitat for maintaining landscape connectivity, particularly when routing multiple different features parallel and near each other. Increased vegetation density along linear features also reduced movement advantages putatively by increasing friction, indicating that actively decommissioning other features such as secondary roads could be an effective mitigation strategy for reducing wolf encounters with prey. Knowing the influence of adjacent habitats on the likelihood of wolves selecting for a given linear feature creates a context to minimize the impact of new anthropogenic features on behaviour.
