Global environmental change may lead to changes in community structure and in species interactions, ultimately changing ecosystem functioning. Focusing on spatial variation in fungus–plant interactions across the rapidly changing Arctic, we quantified variation in the identity of interaction partners. We then related interaction turnover to variation in the bioclimatic environment by combining network analyses with general dissimilarity modelling. Overall, we found species associations to be highly plastic, with major rewiring among interaction partners across variable environmental conditions. Of this turnover, a major part was attributed to specific environmental properties which are likely to change with progressing climate change. Our findings suggest that the current structure of plant-root associated interactions may be severely altered by rapidly advancing global warming. Nonetheless, flexibility in partner choice may contribute to the resilience of the system.

Interreg-Aurora project: Our Precious Transboundary Waters

The brown trout is a socioeconomically important freshwater fish in both Norway and Finland, where habitat fragmentation, overexploitation, translocations, and stocking have led to nationwide decline especially in populations of large growing, adfluvial brown trout and their genetic integrity. Careful conservation and coordinated, sustainable management of the remaining large growing brown trout populations is crucial. For this purpose, our project focuses on the transboundary Lake Inari-Pasvik River catchment as a bilateral model (reference) system, utilizing and requiring cross-border cooperation between Norway and Finland. We combine information on the genetic status of trout populations in the catchment, introduce new research methods and compare existing stocking programs for providing tools and guidelines to support the knowledge-based conservation and management of adfluvial brown trout populations in Norway and Finland.
