CIRCUMPOLAR ASSESSMENT OF TRENDS IN ARCTIC FRESHWATER BIODIVERSITY

The freshwater group of the Circumpolar Biodiversity Monitoring Plan (Arctic Council: Conservation of Arctic Flora and Fauna) has completed circumpolar assessments of freshwater flora and fauna to determine the state of Arctic freshwaters. This evaluation included examination of data from both historical (paleolimnological data and records from 1800 to 1950) and contemporary (post-1950) time scales, as well as Traditional Ecological Knowledge of Arctic peoples. Assessments compared and contrasted the regional state of Arctic freshwater ecosystems in North America, Iceland, Greenland, Fenno-Scandia, and Russia. In addition, circumpolar assessments for specific focal ecosystem components, namely fish, benthic invertebrates, benthic algae, macrophytes and plankton, provided novel analyses of how climate change and associated environmental drivers affect these biological components. We highlight multiple-stressor scenarios that act on the biodiversity and biogeochemistry of Arctic freshwaters, and cause change in biological communities of lakes and streams. This group of studies represents the first circumpolar assessment of trends in Arctic freshwater biodiversity.
