Juvenile life history, migration, and habitat use of natural-versus hatchery-origin Chinook Salmon Open
Objectives Our overall objective was to directly compare the early life history and migration patterns of hatchery- and natural-origin fish and determine when hatchery fish provide good surrogates for natural-origin winter-run Chinook Salm…

The Value of Information is Context Dependent: A Demonstration of Decision Tools to Address Multispecies River Temperature Management Under Uncertainty Open
Trade-offs among objectives in natural resource management can be exacerbated in altered ecosystems and when there is uncertainty in predicted management outcomes. Multi-criteria decision analysis and value of information (VOI) are underut…

Restoring freshwater habitat mosaics to promote resilience of vulnerable salmon populations Open
Phenotypic diversity and abundance drive salmon resilience in the face of increasing environmental variability. But what happens when human activities fundamentally alter the habitat complexity that drives this diversity? And how can we re…

Imperfect detection and misidentification affect inferences from data informing water operation decisions Open
Objective Managers can modify river flow regimes using fish monitoring data to minimize impacts from water management infrastructure. For example, operation of the gate-controlled Delta Cross Channel (DCC) in California can negatively affe…

Considerations for the Development of a Juvenile Production Estimate for Central Valley Spring-Run Chinook Salmon Open
Effective species management depends on accurate estimates of population size. There are, however, no estimates of annual juvenile production for Central Valley spring-run Chinook Salmon (“spring run”), a highly imperiled species in Califo…

Machine Learning Forecasts to Reduce Risk of Entrainment Loss of Endangered Salmonids at Large-Scale Water Diversions in the Sacramento–San Joaquin Delta, California Open
Incidental entrainment of fishes at large-scale state and federal water diversion facilities in the Sacramento-San Joaquin Delta, California, can trigger protective management actions when limits imposed by environmental regulations are ap…

Variation in Juvenile Salmon Growth Opportunities Across a Shifting Habitat Mosaic Open
Historically, Chinook Salmon in the California Central Valley reared in the vast wetlands of the Sacramento–San Joaquin Delta. However, more than 95% of floodplain, riparian, and wetland habitats in the Delta have become degraded because o…

Durability of environment–recruitment relationships in aquatic ecosystems: insights from long‐term monitoring in a highly modified estuary and implications for management Open
The environment can strongly influence the survival and population dynamics of aquatic organisms. Our understanding of these relationships, typically based on simple linear regression, underpins many contemporary resource management decisi…

Shifting Thresholds: Rapid Evolution of Migratory Life Histories in Steelhead/Rainbow Trout,<i>Oncorhynchus mykiss</i> Open
Expression of phenotypic plasticity depends on reaction norms adapted to historic selective regimes; anthropogenic changes in these selection regimes necessitate contemporary evolution or declines in productivity and possibly extinction. A…
