ECOSERV – Ecosystem Services and Climate Change Research Group
Ecosystem services—the benefits that nature provides—are essential for human well-being and climate resilience.
At the University of Eastern Finland, the UEF//ECOSERV Research Group explores how ecosystem structures, functions, and services respond to natural and anthropogenic disturbances under changing climatic conditions. Our work connects ecological research with practical solutions, addressing pressing environmental and societal challenges.
Aims of UEF//ECOSERV
- Ennhance understanding of how disturbances shape ecosystem structure and function.
- Quantify impacts on key ecosystem services, including carbon sequestration, water quality, and biodiversity.
- Develop nature-based solutions and restoration strategies for climate adaptation and mitigation.
- Promote the integration of research, teaching, and community engagement in ecosystem stewardship.
UEF//ECOSERV aims to become a leading hub for multidisciplinary research on ecosystem services and climate change in the Nordic region. By integrating biogeochemistry, ecology, and policy-relevant research, we support evidence-based decision-making for sustainable land management and climate-resilient societies.
Core Research Themes
- Ecosystem Structure
Species composition, biomass dynamics, and the structural integrity of ecosystems. - Ecological Disturbances
Effects of fire, windthrow, and human-induced stressors on ecosystem resilience and restoration. - Carbon Sequestration
Soil carbon dynamics, greenhouse gas emissions, and carbon sink functions in forests and wetlands. - Water Quality
Impacts of land use and disturbances on nutrient runoff and aquatic ecosystems. - Biodiversity and Microbiomes
Biodiversity responses to disturbance, emphasising soil microbial communities and ecosystem functioning. - Cultural and Social Dimensions
Recreational, traditional, and cultural values of ecosystems, and community involvement in restoration efforts.
