My Project

Behavioural impact of human presence on mammal mesopredators in protected areas

Background

When managing wildlife populations, designing protected areas, or considering animal reintroduction from a captive population, the behavioral aspect is often overlooked. Behaviour can be linked to survival or reproductive success, and to welfare. Behavioural responses to new challenges / environmental changes can be the result of immediate modification of individual behaviours, sometimes through a learning process, or of evolutionary adaptation. Behavioural traits can also be spatially distributed depending on their fitness values relative to local contexts. Habituation to humans will affect welfare in captive settings and can have lasting effect on wild populations. It can also lead to human-wildlife conflicts. Other aspects of behaviour, such as learning and problem-solving can exacerbate conflicts. Behaviour varies between species, population or even individuals. Therefore, conflicts can be addressed more precisely with problem populations or individuals.

Conflicts are present in and around protected areas, affecting wildlife and humans alike. Park visitors and park neighbours are two groups of people mostly involved in said conflicts. In Québec’s protected areas, mammal mesopredators (especially raccoon, but also skunk and red fox) are a recurring sources of human-wildlife conflict. Mammal mesopredators make for an interesting research model because they exhibit widely varying behaviours between and within species, many species are widely distributed and relatively abundant, and they are involved in conflict situations. Common species are also important to study because of their ecological impact as widespread keystone components of their communities.

Field Work

The research will be conducted at national parks in southern Québec, from the SÉPAQ network of protected areas. Sites will be selected based on the presence of studied species, occurrence of human-wildlife conflicts, and level of human activities. Some field work might be conducted in the peripheral zones of the parks.


Objectives

Review current knowledge on human-wildlife conflicts involving mammal mesopredators and explore the impact of human activities, density, and land protection statues. Investigate the difference in learning and problem-solving abilities between animals (individuals and/or species) in relation to their exposure to humans. Investigate the impact of habituation on wildlife and the probability of conflict. Investigate if the presence of a behavioural trait in a specific area is the result of learning and habituation, or of immigration and emigration.
