Tundra Nunavik: Matrix of trophic relations

While most ecological studies focus on the impact of climate change on some populations or species, it becomes clear that ecosystem-based information is needed to better predict the future state of the Arctic. We therefore conducted a large-scale study aimed at characterizing the vulnerability of tundra ecosystems to climate change through modelling. After having identified mammal and bird species inhabiting the province of Qubec north of the 50th parallel, we built a matrix of trophic relations including every known predator-prey relationship.
