We welcome you to a full-day symposium highlighting current research and emerging insights from the Krycklan Catchment Study. The 2025 edition will focus on advancing our understanding of forest and water systems in the context of a changing climate, with sessions designed to foster interdisciplinary dialogue and collaboration.

Preliminary Session Themes:

Keynote Talks: We are pleased to welcome a distinguished lineup of keynote speakers, each offering fresh perspectives on boreal ecosystems, hydrology, and biogeochemistry:

• King Carl XVI Gustaf’s guest Professor  James Kirchner, ETH Zürich – Internationally recognized for his pioneering work in catchment hydrology, including flow pathways, solute transport, and environmental tracer applications.

• Sandra Jämtgård, SLU – A leading expert in soil biogeochemistry, with a particular focus on nitrogen cycling and plant–microbe interactions in forest systems.

• Hyungwoo Lim, SLU – A researcher in ecophysiology in boreal landscapes.

• Karin Eklöf, SLU – Renowned for her work on contaminant dynamics, particularly mercury cycling and water–soil interactions in forested catchments.

Join us for inspiring keynote talks from leading experts highlighting recent advances and interdisciplinary insights in ecosystem biogeochemistry

Session 1:

Natural Streams and Modified Waterways Topics may include stream network mapping, hydromorphology, aquatic biodiversity, and the impacts of land use change or restoration efforts on hydrological and ecological processes.

Session 2:

Terrestrial Dynamics in Boreal Landscapes This session will address drought regimes, vegetation–climate interactions, and soil–plant–atmosphere processes relevant to boreal ecosystem functioning under environmental change.

Lightning Poster Session:

A dynamic, fast-paced session where poster presenters give brief overviews of their research to the audience. This will be followed by an extended interactive poster viewing and discussion period to foster informal exchanges and networking.

The Krycklan Symposium convenes a diverse academic community—including scientists, doctoral researchers, engineers, and technicians—who contribute to long-term, multidisciplinary research in northern Sweden’s boreal biome.

There are no registration fees or costs for meals. Participation is free of charge, but advance registration is required.
