Migration in drought: Receding streams contract the seaward migration window of endangered salmon

Ecosphere, 2022
Prolonged migration windows buffer migratory animal populations against uncertainty in resource availability. Understanding how intensifying droughts from climate change influence the migration window is critical for biodiversity conservation in a ...

Freshwater hydrology emerges as the strongest predictor of phenological variability in a Southeast Alaska steelhead trout (Oncorhynchus mykiss) population

Journal of Fish Biology, EarlyView.
Abstract Phenological variation, such as the migration trends of salmonids, may provide resilience in changing environmental scenarios, influencing individual survival and population productivity. Phenological shifts may be particularly consequential for anadromous species that rely on seasonal cues for migration between freshwater and marine habitats ...

The Fate of Coho Salmon Nomads: The Story of an Estuarine-Rearing Strategy Promoting Resilience

Ecology and Society, 2009
The downstream movement of coho salmon nomads (age 0), conventionally considered surplus fry, has been an accepted characteristic of juvenile coho salmon for the past 40 to 50 yr.

Evaluating Coexistence of Fish Species with Coastal Cutthroat Trout in Low Order Streams of Western Oregon and Washington, USA

Fishes, 2021
When multiple species of fish coexist there are a host of potential ways through which they may interact, yet there is often a strong focus on studies of single species without considering these interactions.

Expert‐Based Prioritization of Control Measures for Salmonid Rickettsial Septicemia in Chilean Salmon Aquaculture

Journal of Fish Diseases, EarlyView.
ABSTRACT Piscirickettsiosis (SRS) remains the main infectious disease affecting salmon aquaculture in Chile. This study evaluated expert perceptions of the effectiveness of SRS control measures and the level of agreement among industry professionals.

Development of a Multiplex Polymerase Chain Reaction Assay for Differentiating Three Lactococcus Species Associated With Piscine Lactococcosis

Journal of Fish Diseases, EarlyView.
ABSTRACT Piscine lactococcosis is an important bacterial disease of farmed fish. The causative agents, Lactococcus garvieae, Lactococcus petauri and Lactococcus formosensis, are closely related, which complicates species‐level identification. We developed a conventional multiplex PCR assay targeting species‐specific genes identified by comparative ...

Using environmental DNA to identify emerging Pacific salmon habitats and support Indigenous governance

Ecological Applications, Volume 36, Issue 7, October 2026.
Abstract Northern watersheds are facing rapid hydroclimatic reorganization driven by climate warming, glacier retreat, and intensifying land use. These changes are altering the distribution and accessibility of aquatic habitats, creating both risks and opportunities for cold‐adapted species such as Pacific salmon (Oncorhynchus spp.).

Opportunistic Feeding and Parasite Assemblages in Sei Whales (Balaenoptera borealis) From Southern Chile Revealed by DNA Metabarcoding

Ecology and Evolution, Volume 16, Issue 10, October 2026.
This study represents the first metabarcoding‐based description of prey composition and parasite‐associated taxa in stranded sei whales from southern South America. ABSTRACT Balaenopterid whales are major consumers in pelagic ecosystems and play a fundamental role in marine food webs.
