Contrasting Life History Characteristics Between Riverine and Lacustrine Anadromous Arctic Char (Salvelinus alpinus) in the Western Canadian Arctic [PDF]

open access: yesEcology and Evolution
Freshwater habitat characteristics are known to affect life history traits of migratory salmonids. Although the life cycle of the anadromous form of Arctic char (Salvelinus alpinus) is typically associated with lakes, there is a small number of ...

Adaptation in landlocked Atlantic salmon links genetics in wild and farmed salmon to smoltification [PDF]

open access: yesBMC Genomic Data
Increased knowledge of heritable traits in Atlantic Salmon (Salmo salar) is important to overcome bottlenecks in salmonid aquaculture. Atlantic salmonid populations, both landlocked and anadromous, represent an interesting model to gain insight into ...

Leveraging the genetic diversity of trout in the rivers of the British Isles and northern France to understand the movements of sea trout (Salmo trutta L.) around the English Channel [PDF]

open access: yesEvolutionary Applications
Populations of anadromous brown trout, also known as sea trout, have suffered recent marked declines in abundance due to multiple factors, including climate change and human activities.

Genetic divergence and one‐way gene flow influence contemporary evolution and ecology of a partially migratory fish [PDF]

open access: yesEvolutionary Applications
Recent work has revealed the importance of contemporary evolution in shaping ecological outcomes. In particular, rapid evolutionary divergence between populations has been shown to impact the ecology of populations, communities, and ecosystems.

Effects of plunge pool configuration on downstream passage survival of juvenile blueback herring

open access: yesAquaculture and Fisheries, 2021
Anadromous alosines are widespread throughout the Northern Hemisphere. Juveniles of this clade are notoriously fragile animals that are at high risk of injury and death associated with passage at hydroelectric facilities.

A hierarchical model of daily stream temperature using air-water temperature synchronization, autocorrelation, and time lags [PDF]

open access: yesPeerJ, 2016
Water temperature is a primary driver of stream ecosystems and commonly forms the basis of stream classifications. Robust models of stream temperature are critical as the climate changes, but estimating daily stream temperature poses several important ...

Seven dam challenges for migratory fish: insights from the Penobscot River

open access: yesFrontiers in Ecology and Evolution, 2023
More than a century of impoundments in the Penobscot River, Maine, USA, has contributed to population declines in migratory fish in the system. A decade of change, research, and monitoring has revealed direct and indirect ways that dams have influenced ...

Distinct intestinal microbial communities of two sympatric anadromous Arctic salmonids and the effects of migration and feeding

open access: yesArctic Science, 2021
Although intestinal microbial communities from anadromous Arctic char (Salvelinus alpinus (Linnaeus, 1758)) in Kitikmeot, Nunavut, Canada, differ depending on the timing and location of capture, determinants of gut microbiota in other wild Arctic ...

Colonization of a temperate river by mobile fish following habitat reconnection

open access: yesEcosphere, 2023
Mobile species are particularly affected by artificial barriers requiring large investments to restore connectivity. However, few large‐scale, long‐term studies have investigated the ecological outcomes of restoring connectivity for these species.

Environmental DNA is an effective tool to track recolonizing migratory fish following large‐scale dam removal

open access: yesEnvironmental DNA, 2021
Environmental DNA (eDNA) has emerged as a potentially powerful tool for use in conservation and resource management, including for tracking the recolonization dynamics of fish populations.
