Analysis of several long-term time-series datasets indicates that the age–size class structure of many Chinook salmon populations has changed over the past several decades, with salmon becoming on average both smaller and younger…

Retrospective testing of a lab-fitted model against long-term field data revealed that lab experiments consistently overestimated the maximal thermal tolerance of embryonic Chinook salmon in natural settings…

Many coastal fishing communities the world over focus their fishing efforts on a small number of target species without explicitly maintaining capacity to take advantage of other potential marine resources…

Rebounding beaver populations are re-engineering some rivers, allowing recovery of some of the lost habitat features important for stream-rearing fish…

Enhancement of salmon stocks with hatchery-raised individuals is often used as a means of restoring depleted populations or supplementing healthy ones, but studies of its effectiveness have produced mixed results…

Prevailing ocean conditions in the North Pacific are highly influenced by complex interactions between various meteorological phenomena expressed across vast spatial scales…
