Despite common misconceptions, fungi do thrive in the Arctic — though their species diversity is lower than in temperate regions, their biomass is surprisingly substantial. In this presentation, Lawrence explores the fascinating adaptations that allow Arctic fungi to survive in extreme cold conditions. For example, some boletes possess sterile cells that serve to protect their fertile cells, showcasing unique survival strategies. Additionally, he touches on the distinctive perspectives indigenous peoples hold regarding fungi in these environments.

The latter part of the talk addresses the impacts of climate change on Arctic fungal communities. Established species are disappearing while new species from southern regions are emerging. This shift, combined with the arrival of new vascular plants that outcompete older species, is disrupting critical mycorrhizal relationships. Long-adapted fungi are losing their specialized cold-weather features, such as boletes exhibiting fewer protective sterile cells.

Ultimately, while fungi will continue to exist in the Arctic, the species composition and ecological dynamics are rapidly transforming — offering a glimpse into a changing world beneath the snow and ice.
