The key role of local and global farmer networks in the development of conservation agriculture in California

Journal of Environmental Quality, EarlyView.
Abstract This article chronicles the history of California's Conservation Agriculture Systems Innovation (CASI) Center and how it has increased agricultural sustainability in the San Joaquin Valley, a major production area for the United States, by using agroecological practices to reduce soil erosion and conserve soil moisture, champion systems ...

The global contribution of forage fish to marine fisheries and ecosystems

Fish and Fisheries, 2014
Forage fish play a pivotal role in marine ecosystems and economies worldwide by sustaining many predators and fisheries directly and indirectly. We estimate global forage fish contributions to marine ecosystems through a synthesis of 72 published Ecopath

Trade‐offs between predation risk and forage differ between migrant strategies in a migratory ungulate

Ecology, 2009
Trade-offs between predation risk and forage fundamentally drive resource selection by animals. Among migratory ungulates, trade-offs can occur at large spatial scales through migration, which allows an "escape" from predation, but trade-offs can also ...

A MULTI‐SCALE TEST OF THE FORAGE MATURATION HYPOTHESIS IN A PARTIALLY MIGRATORY UNGULATE POPULATION

Ecological Monographs, 2008
The forage maturation hypothesis (FMH) proposes that ungulate migration is driven by selection for high forage quality. Because quality declines with plant maturation, but intake declines at low biomass, ungulates are predicted to select for intermediate
