Johan Olofsson is a Professor at the Department of Ecology and Environmental Science, Umeå University. His research focuses on Arctic ecosystems, particularly the interactions between climate, vegetation, and herbivores like lemmings and reindeer. He leads the 'Terrestrial ecology' research group and has conducted fieldwork in Abisko, northern Sweden for nearly three decades. Key methodologies include herbivore exclusion enclosures, drone-based vegetation mapping, and camera trap monitoring.
Research interests include winter ecosystem dynamics, climate change impacts, and herbivore effects on tundra biodiversity. Current projects examine circumpolar herbivore influences, mechanisms of ecosystem function alteration, and spatial/temporal scaling of herbivore effects. Notable methods involve UAVs for vegetation analysis and deep learning for ecological impact assessments.
Recent publications highlight earthworm invasions' carbon impacts, UAV applications in ant mound mapping, and reindeer grazing's role in mitigating climate-driven vegetation shifts. His work bridges field observations with large-scale synthesis datasets to address Arctic environmental challenges.
Grants and collaborations support circumpolar studies and permafrost research. He heads the 'Do reindeer protect arctic diversity in a changing climate' project (2023-2025). His lab focuses on advancing understanding of Arctic ecosystem resilience through interdisciplinary approaches.
