Collaborative Research: Shifting seasonality of Arctic river hydrology alters key biotic linkages among aquatic systems
This research will determine how the shifting seasonality of arctic river hydrology alters key biotic linkages within and among lake and stream components of watersheds and may alter the function of the arctic system. Arctic grayling (Thymallus arcticus) is a quintessential, circumpolar arctic speci...

This research will determine how the shifting seasonality of arctic river hydrology alters key biotic linkages within and among lake and stream components of watersheds and may alter the function of the arctic system. Arctic grayling (Thymallus arcticus) is a quintessential, circumpolar arctic species that provides a model system for understanding the impacts of changing seasonality on arctic ecosystem function because an interconnected and varied landscape (large tundra rivers, small streams and lakes) is required to maintain their population viability. Changes to environmental conditions that disrupt their migration will affect the system-level function of aquatic ecosystems. Grayling serve as food for other biota, including lake trout, birds and humans, and as top-down controls in stream ecosystems suggesting that changes to their populations will have effects that reverberate throughout the coupled river-lake system.
