Large dam removal is being used to restore river systems, but questions remain regarding
their outcomes. We examine how the removal of two large dams in the Elwha River, coupled …

Rapid adaptation to novel environments may drive changes in genomic regions through
natural selection. Such changes may be population-specific or, alternatively, may involve …

Unsupervised clustering algorithms, like the program Structure, are increasingly used to
infer the presence of population structure from a sample of genotyped individuals. We …

Dam construction and longitudinal river habitat fragmentation disrupt important life histories
and movement of aquatic species. This is especially true for Oncorhynchus mykiss that …

Local extirpations of Pacific salmon Oncorhynchus spp. and steelhead O. mykiss, often due
to dams and other stream barriers, are common throughout the western United States …

The streams draining of into San Francisco Bay, California, have been impacted by habitat
alteration for over 150 years, and roads, dams, water diversions, and other impediments …

Adaptation to novel habitats and phenotypic plasticity can be counteracting forces in
evolution, but both are key characteristics of the life history of steelhead/rainbow trout …
