The Stream Quantification Tool (SQT) has been adapted specific to wadeable, non-glacial streams in Interior Alaska.

Migratory ungulates are an essential part of natural ecosystems. The migrations also contribute to local and regional economies through harvest and tourism and are woven into the culture of numerous communities. This new global initiative aims to map and conserve ungulate migration corridors.

Marine heatwaves are expected to become more common and widespread as a consequence of climate change. From primary producers to top-level consumers, our studies offer insight as to the varying extent of species’ responses to a wide-scale perturbation.

Peatlands have a moderating effect on the Earth's climate. This assessment looks at the status of peatlands of the world and what impact they can have on the climate in the future.

Human activities are rapidly altering the natural world. Nowhere is this more evident, perhaps, than in the Arctic, yet this region remains one of the most remote and difficult to study. Researchers have increasingly relied on animal tracking data in these regions to understand individual species' responses, but if we want to understand larger-scale change, we need to integrate our understanding across species.

Banding shorebirds has provided long-term data related to the areas the birds use seasonally and during migration. By understanding their movement patterns and their population dynamics, we can identify critical areas, worldwide, for their conservation.

A major marine heatwave of 2014-2016 sent changes rippling through ocean ecosystems, changing the food web and caused massive seabird die-offs.

It has long been assumed that caribou have one of the longest land migrations, but this worldwide study of animal migrations confirms it! There is more to the wildlife migration story, read more here.

The Arctic parks in Alaska are losing lake habitat important to birds and other species, even though precipitation has remained largely the same over time. Like many changes in the Arctic, the disappearance of lakes has been accelerated by warming temperatures.
