Birds and mammals of Nunavik in a context of press and pulse

International audience Nunavik is a biogeographical transition zone between the Hudsonian forest and the tundra, with mammal and bird communities from both biomes. These species are subject to pressures (long-term) linked to climate change and pulses (short-term) linked to anthropogenic disturbances...

Description
Summary:International audience Nunavik is a biogeographical transition zone between the Hudsonian forest and the tundra, with mammal and bird communities from both biomes. These species are subject to pressures (long-term) linked to climate change and pulses (short-term) linked to anthropogenic disturbances (e.g., human frequentation) or extreme events (such as the fires of summer 2023). This presentation meets three objectives: (1) to characterize the biogeographical originality of Nunavik's bird and mammal communities on a North American scale, in order to estimate their potential vulnerability to climate change; (2) to document the presence of mammals and birds as a function of a set of anthropogenic pressures through a first year of photo and audio trap monitoring from 2022 to 2023 (3) evaluate the arrival dates of birds on their nesting sites and a possible influx of birds linked to forest fires further south, using audio trap data and field observations carried out in July 2023.
