Changing Arctic ecosystems: ecology of loons in a changing Arctic [ More info] Changes in Arctic sea ice and permafrost will likely affect populations of wildlife. Migratory birds such as loons rely on freshwater lakes in the Arctic for nesting and food supply; we are studying how their populations are affected by these changes.
Changing Arctic ecosystems: resilience of caribou to climatic shifts in the Arctic [ More info] Land management agencies need to know how changes in vegetation resulting from climate change may affect wildlife habitat and the food resources that caribou rely on.
Environmental Monitoring and Assessment Program Western Pilot Project - Conditions of North Dakota Perennial Streams for Water Chemistry and Mercury in Fish Tissue, 2000-2003 [ More info] Sixty-five sampling sites, selected by a statistical design to represent lengths of perennial streams in North Dakota, were chosen to be sampled for water chemistry and mercury in fish tissue to establish unbiased baseline data.
