Environmental correlates of population differentiation in Atlantic herring.
The marine environment is characterized by few physical barriers, and pelagic fishes commonly show high migratory potential and low, albeit in some cases statistically significant, levels of genetic divergence in neutral genetic marker analyses. However, it is not clear whether low levels of differentiation reflect spatially separated populations experiencing gene flow or shallow population his...
متن کاملOceanographic connectivity and environmental correlates of genetic structuring in Atlantic herring in the Baltic Sea
Marine fish often show little genetic structuring in neutral marker genes, and Atlantic herring (Clupea harengus) in the Baltic Sea are no exception; historically, very low levels of population differentiation (F ST ≍ 0.002) have been found, despite a high degree of interpopulation environmental heterogeneity in salinity and temperature. Recent exome sequencing and SNP studies have however show...
متن کاملPopulation-scale sequencing reveals genetic differentiation due to local adaptation in Atlantic herring.
The Atlantic herring (Clupea harengus), one of the most abundant marine fishes in the world, has historically been a critical food source in Northern Europe. It is one of the few marine species that can reproduce throughout the brackish salinity gradient of the Baltic Sea. Previous studies based on few genetic markers have revealed a conspicuous lack of genetic differentiation between geographi...
متن کاملEnvironmental Factors and Natural Resource Stock: Atlantic Herring Case
Herring is an important stock as bait for lobster fisheries and a component of the food web of the Northwest Atlantic Ocean. However, herring is very vulnerable to environmental variables such as temperature, food supply, and to the type of sediment on the bottom floor. Egg and larval stage herring are hypothesized to be very sensitive to low temperatures. This paper will analyze the correlatio...
متن کاملGenetic Differentiation, Temporal Stability, and the Absence of Isolation by Distance among Atlantic Herring Populations
—The genetic variation among 17 spawning groups of Atlantic herring Clupea harengus was assessed at several temporal and spatial scales using nine tetranucleotide microsatellites. PanAtlantic samples were drawn from the Scotian Shelf, the Celtic Sea, the Baltic Sea, and coastal Iceland. Significant differentiation was observed between northeastern and northwestern Atlantic herring (FST ; 0.065)...
