08/06/2020. Arctic freshwater ecosystems and their biological diversity require standardized monitoring across all northern countries! Arctic nature is facing unprecedented changes. Existing monitoring data show that the diversity, structure and functions of Arctic freshwaters are currently undergoing rapid and likely irreversible changes. Climate change in association with resulting permafrost thaw, eutrophication and replacement of unique northern species by southern immigrants are contributing to these rapid changes. This trend affects the livelihoods and culture of Indigenous Peoples living in close connection with Arctic nature. Knowledge on the status of Arctic freshwaters and biotas is geographically scattered and temporally limited, which hinders launching international programs for conservation of Arctic freshwaters or for managing economically valuable fish and wildlife species.
A new opinion article on this timely topic was published in Journal of Applied Ecology’s Policy Forum on Monday. The international team included researchers from Finland, Canada and Sweden. Read the open access paper here.
