Content

Many boreal and arctic regions have already exceeded the global no-go temperature increase of 2o C. Many ecosystems are being impacted with much more disruption expected. While, from a global perspective, the north is far from a biodiversity hotspot, it hosts a functionally unique set of taxa evolved to withstand extremes or to migrate extreme distances to avoid the extremes. Using a case study of Canadian terrestrial vertebrates, we re-evaluate the latitudinal richness gradient from a functional perspective and ask how much diversity could be lost following a range of scenarios (climate change, loss of megafauna, loss of species at risk). We demonstrate how each scenario impacts the functioning of ecological communities defined from both a trait-based and food web perspective. The north suffers disproportionate losses regardless of the definition of function. More species would be impacted in most scenarios in the north, and those species collectively represent unique functions not seen in temperate regions.

BD-Seminars

The Biodiversity Seminar Series (BD-Seminars) are organized by the WSL Biodiversity Center. Every two weeks, we aim to host a seminar speaker that presents research or outreach on topics relevant to the biodiversity community at WSL. The seminars are public and are usually broadcasted online.
