Landscape conservation cooperatives (LCCs) are conservation-science partnerships between the U.S. Fish and Wildlife Service, U.S. Geological Survey (USGS), and other federal agencies, states, tribes, NGOs, universities and stakeholders within a geographically defined area. They inform resource management decisions to address national-scale stressors-including habitat fragmentation, genetic isolation, spread of invasive species, and water scarcity-all of which are accelerated by climate change.

An Investigation of the Potential Effects of Selective Exploitation on the Demography and Productivity of Yukon River Chinook Salmon
Yukon River Chinook salmon (Oncorhynchus tshawytscha) have been targeted in large-mesh gill net fisheries for over 100 years. Recent reductions in productivity and perceptions of reduced size and earlier age at maturation have elevated concerns regarding the potential consequences of the selective exploitation of large fish. Investigations associating changes in population productivity and demography, particularly size and age composition, with overharvest and selective exploitation are common in the fisheries literature. However, most such investigations have considered long-lived species repeatedly subject to exploitation, often prior to maturation. Similar investigations concerning semelparous Pacific salmon...
