Fish scales have long been used to reconstruct fine-scale habitat transitions such as the movement of juvenile fish
from freshwater, estuary, and ocean environments. Despite the importance of life history information to fisheries

Because of this threat, energy and fish and wildlife interests risk a lose-lose proposition, the "field day" in which national energy entrepreneurs and federal deficit cutters would revel, if the Northwest fails to unite. Regional energy...

Spring Chinook salmon, Oncorhynchus tshawytscha, are transported above dams in the Willamette River to provide access to blocked spawning habitat. However, 30-95% of these transplants may die before spawning in some years. To varying degrees,...

Neutral genetic markers are routinely used to define distinct units within species
that warrant discrete management. Human-induced changes to gene flow however
may reduce the power of such an approach. We tested the efficiency of adaptive
