OTOLITH MICROCHEMISTRY INDICATES UNEXPECTED PATTERNS OF RESIDENCY AND ANADROMY IN BLUEBACK HERRING, ALOSA AESTIVALIS, IN THE HUDSON AND MOHAWK RIVERS.

Knowledge and Management of Aquatic Ecosystems, 2001
Blueback herring is an anadromous fish endemic in the tidal Hudson River Estuary, USA. Twentieth-century improvements to a lock and canal system permitted the species to invade the Hudson’s main tributary, the Mohawk River, where it has been recorded ...

Trapped in the nursery: poor growth and condition in juvenile alewives (Alosa pseudoharengus) stemming from drought-imposed loss of connectivity to marine habitat

Frontiers in Marine Science
IntroductionNursery habitats sustain populations only when individuals are able to move to habitats used by later life stages. For anadromous fishes such as Alewife (Alosa pseudoharengus), anthropogenic barriers and drought can disrupt this connectivity,

Evolutionary patterns of diadromy in fishes: more than a transitional state between marine and freshwater

BMC Evolutionary Biology, 2019
Background Across the tree of life there are numerous evolutionary transitions between different habitats (i.e., aquatic and terrestrial or marine and freshwater).

Evolution of a stream ecosystem in recently deglaciated terrain

, 2011
Climate change and associated glacial recession create new stream habitat that leads to the assembly of new riverine communities through primary succession.

Low genetic and phenotypic divergence in a contact zone between freshwater and marine sticklebacks: gene flow constrains adaptation [PDF]

, 2017
Background Distinct hybrid zones and phenotypic and genomic divergence is often observed between marine and freshwater threespine sticklebacks (Gasterosteus aculeatus).

Juvenile salmonids traverse coastal meta‐nurseries that connect rivers via the sea

Frontiers in Ecology and the Environment, Volume 23, Issue 8, October 2025.
Conventionally, juvenile salmonids are thought to migrate unidirectionally from freshwater systems to marine systems and therefore only inhabit natal drainages. Although scattered evidence suggests juveniles can move bidirectionally between freshwater rivers and the ocean, including into non‐natal drainages, such movements have never been documented ...

Genetic Considerations for Sourcing Steelhead Reintroductions: Investigating Possibilities for the San Joaquin River

San Francisco Estuary and Watershed Science, 2014
Steelhead trout (Oncorhynchus mykiss) historically occurred in all major watersheds along the west coast of the United States. They can be a vital part of a healthy riverine ecosystem, are highly valued for fishing, and have been greatly affected by ...

Genetic data confirm the presence of juvenile Alosa alosa in the estuary of the River Tamar

Aquaculture, Fish and Fisheries
Within the UK, allis shad (Alosa alosa) are classified as Critically Endangered and are known to breed in only a single river, the Tamar. Despite evidence of spawning within the lower freshwater reaches of the river and at the tidal limit within the ...

Restricted gene flow at the micro- and macro-geographical scale in marble trout based on mtDNA and microsatellite polymorphism [PDF]

, 2011
Background The genetic structure of the marble trout Salmo trutta marmoratus, an endemic salmonid of northern Italy and the Balkan peninsula, was explored at the macro- and micro-scale level using a combination of mitochondrial DNA (mtDNA) and ...
