We hypothesized that changes in southeastern Bering Sea foraging conditions for black-legged kittiwakes (Rissa tridactyla)
have caused shifts in habitat use with direct implications for population trends. To test this, we compared at-sea
distribution, breeding performance, and nutritional stress of kittiwakes in three years (2008–2010) at two sites in the...

Dams impound the majority of rivers and provide important societal benefits, especially daily water releases that enable on-peak hydroelectricity generation. Such “hydropeaking” is common worldwide, but its downstream impacts remain unclear. We evaluated the response of aquatic insects, a cornerstone of river food webs, to hydropeaking using a life history–hydrodynamic...

Summertime carbon, nitrogen, and biogenic silica export was examined using ²³⁴Th:²³⁸U disequilibria combined with free floating sediment traps and fine scale water column sampling with in situ pumps (ISP) within the Eastern Tropical North Pacific and the Gulf of California. Fine scale ISP sampling provides evidence that in this system,...

There are many reasons for building an alliance among agencies and citizens in forest and rangeland communities. In the big picture, the purpose is primarily to reach decisions that are objectively better. Essentially, the quality of decisions is improved by a multi-agency effort that includes a role for citizens and...
The Willamette Basin Conservation Project was created to help people and programs work together toward positive results in Oregon’s Willamette Basin for people, lands, communities, waters and native species.
