ABSTRACT The 27,540-ha (68,000-acre) Sacramento–San Joaquin River Delta of northern
California is the largest freshwater estuary on the western coast of the United States. The …

We developed a novel statistical model to relate the daily survival and migration dynamics of
an endangered anadromous fish to river flow and water temperature during both extreme …

Contrary to small-and medium-sized rivers, little attention has been paid to the downstream
migration of Atlantic salmon smolts in large-sized rivers and the size-related impact of …

Many river systems within the Central Valley of California have been disconnected from their
floodplains, hypothesized to be partially responsible for declining Chinook salmon …

Substantial increases in non-native aquatic vegetation have occurred in the upper San
Francisco Estuary over the last 2 decades, largely from the explosive growth of a few …

Grass carp Ctenopharyngodon idella have been widely introduced in aquatic ecosystems to
combat outbreaks of problem aquatic plants. However, the extent to which introduced carp …

Variations in species distribution, population structure, and behavior can provide a portfolio
effect that buffers populations against rapid environmental change. Although diversity has …

Spatial variation in habitat structure is a well-recognized characteristic of lotic ecosystems.
The resulting patchwork mosaic provides opportunities for growth and survival as well as …

Floodplains provide multiple benefits to both resident and migratory fish species, including
juvenile Chinook Salmon Oncorhynchus tshawytscha, but direct comparisons of survival …

Background Acoustic telemetry is a powerful tool for studying fish behavior and survival that
relies on the assumption that tag detection reflects the presence of live study subjects. This …
