Hyper- and Hypo-Osmoregulatory Performance of Atlantic Salmon (Salmo salar) Smolts Infected With Pomphorhynchus tereticollis (Acanthocephala)

Frontiers in Ecology and Evolution, 2021
Migratory species must cope with different parasite communities in different environments, but little is known about the ecophysiological effects of parasites on migratory performance.

Anadromy, potamodromy and residency in brown trout Salmo trutta: the role of genes and the environment. [PDF]

J Fish Biol, 2019
AbstractBrown trout Salmo trutta is endemic to Europe, western Asia and north‐western Africa; it is a prominent member of freshwater and coastal marine fish faunas. The species shows two resident (river‐resident, lake‐resident) and three main facultative migratory life histories (downstream–upstream within a river system, fluvial–adfluvial ...

Do offspring characteristics reflect parental migration variation? [PDF]

J Fish Biol
Abstract Sea trout, Salmo trutta, display a wide range of migratory behaviours, and one aspect of variation comes from freshwater migration distance. The overall aim of this study was to determine if offspring of long‐ and short‐distance migrants exhibited phenotypic differences relating to parental migration distance.

Expected Climate Change in the High Arctic—Good or Bad for Arctic Charr?

Fishes, 2023
Lakes in the High Arctic are characterized by their low water temperature, long-term ice cover, low levels of nutrients, and low biodiversity. These conditions mean that minor climatic changes may be of great importance to Arctic freshwater organisms ...

The ways in which fish use estuaries: a refinement and expansion of the guild approach [PDF]

, 2013
© 2013 John Wiley & Sons Ltd. This study refines, clarifies and, where necessary, expands details of the guild approach developed by Elliott et al. (2007, Fish and Fisheries 8: 241-268) for the ways in which fish use estuaries.

Juvenile salmon habitat use drives variation in growth and highlights vulnerability to river fragmentation

Ecosphere, 2022
Widespread stream network fragmentation from dams and culverts has altered habitat connectivity in river ecosystems and presents an acute threat to migratory fish.

Climate vulnerability assessment for Pacific salmon and steelhead in the California Current Large Marine Ecosystem. [PDF]

, 2019
Major ecological realignments are already occurring in response to climate change. To be successful, conservation strategies now need to account for geographical patterns in traits sensitive to climate change, as well as climate threats to species-level ...

Comparison of anadromous and landlocked Atlantic salmon genomes reveals signatures of parallel and relaxed selection across the Northern Hemisphere

Evolutionary Applications, 2021
Most Atlantic salmon (Salmo salar L.) populations follow an anadromous life cycle, spending early life in freshwater, migrating to the sea for feeding, and returning to rivers to spawn.

No evidence for the radiation time lag model after whole genome duplications in Teleostei. [PDF]

, 2017
The short and long term effects of polyploidization on the evolutionary fate of lineages is still unclear despite much interest. First recognized in land plants, it has become clear that polyploidization is widespread in eukaryotes, notably at the origin
