Brown trout Salmo trutta is endemic to Europe, western Asia and north‐western Africa; it is a
prominent member of freshwater and coastal marine fish faunas. The species shows two …

The Endangered Species Act (ESA) requires that the National Marine Fisheries Service
(NMFS) review the status of listed species under its authority at least every five years and …

Males and females often differ in their fitness optima for shared traits that have a shared
genetic basis, leading to sexual conflict. Morphologically differentiated sex chromosomes …

Migration is essential for the reproduction and survival of many animals, yet little is
understood about its underlying molecular mechanisms. We used the salmonid …

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 …

The removal of two large dams on the Elwha River was completed in 2014 with a goal of
restoring anadromous salmonid populations. Using observations from ongoing field studies …

Salmonids are some of the most widely studied species of fish worldwide. They span
freshwater rivers and lakes to fjords and oceans; they include short‐and long‐distance …

This paper reviews the life history of brown trout and factors influencing decisions to migrate.
Decisions that maximize fitness appear dependent on size at age. In partly anadromous …

Lifetime reproductive success (LRS), the number of offspring produced over an organism's
lifetime, is a fundamental component of Darwinian fitness. For taxa such as salmonids with …

Glaciers have shaped past and present habitats for Pacific salmon (Oncorhynchus spp.) in
North America. During the last glacial maximum, approximately 45% of the current North …
