the Sacramento and San Joaquin rivers, which flow through California's Central Valley and …

Introgressive hybridization threatens the persistence of several species of native salmonids
in the western United States, but little is known about the factors influencing the …

The examination of population-specific adaptations of introduced salmonids to the wide
range of environments found in Patagonia (southern South America) can help unveil some …

Brown trout (Salmo trutta) exhibit highly diverse life histories varying from resident, slow-
