Using Drone‐Derived Imagery to Describe Prey Sharing Behaviors in Two Piscivorous Resident Killer Whale Populations

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Cooperative foraging occurs across diverse taxa and facilitates prey acquisition and social learning, particularly when prey is shared among group members. In Resident killer whales (Orcinus orca ater), prey sharing is central to how individuals acquire salmonid prey, yet current research has relied primarily on boat‐based observations.

The impacts of biological invasions

Biological Reviews, Volume 101, Issue 3, Page 1255-1310, June 2026.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Aerobic scope is sustained through a heatwave in juvenile Atlantic salmon (Salmo salar)

Journal of Fish Biology, Volume 108, Issue 6, Page 1852-1864, June 2026.
Abstract Aquatic ectotherms are vulnerable to heatwave‐induced physiological stress, which arises from increased energy demands and reduced dissolved oxygen content in warmer waters. Understanding thermal physiology is critical for predicting how commercially and ecologically important populations could be affected by the increasing risk of rising ...

Rapid increase in abundance and distribution of invasive pink salmon (Oncorhynchus gorbuscha) within a diverse, large Barents Sea catchment

Journal of Fish Biology, Volume 108, Issue 6, Page 1875-1888, June 2026.
Abstract Pink salmon originate from the North Pacific area but were introduced into northwest Russia from the late 1950s onwards. Since 2017, the alien species has increased dramatically in abundance and rapidly invaded adjacent areas of the North Atlantic region.

Non‐native pink salmon Oncorhynchus gorbuscha carcasses benefit native benthic macroinvertebrates

Journal of Fish Biology, Volume 108, Issue 6, Page 1825-1837, June 2026.
Abstract The invasion of the North Atlantic by pink salmon Oncorhynchus gorbuscha has raised concerns regarding their impact on coastal rivers. Although the influence of marine‐derived nutrients from returning adult O. gorbuscha on rivers in their native range has received much attention, the ecological consequences of invasive O.

Perceptions of common‐pool resource management in the Tana River, Norway: An exploratory analysis

Ecosphere, Volume 17, Issue 5, May 2026.
Abstract The sustainable management of common resources such as wild Atlantic salmon in the Tana River, Norway, is a significant challenge, as it involves a public goods dilemma where individual interests can conflict with collective interests. This study explores local perceptions of common‐pool resource management in the Tana River using vignettes ...

Methemoglobin determination by multi-component analysis in coho salmon (Oncorhynchus kisutch) possessing unstable hemoglobin

MethodsX, 2020
Hemoglobin derivatives are often quantified in blood to establish cardio-respiratory status and possible causes of impaired oxygen transport. The derivative known as methemoglobin results from oxidation of hemoglobin and is pathologically relevant ...

Wood restoration results in rapid conversion of a degraded plane‐bed channel, Little River, Washington

Earth Surface Processes and Landforms, Volume 51, Issue 5, May 2026.
The authors document that wood restoration can rapidly and positively affect a number of geomorphic variables to improve habitat conditions for Pacific salmon. Abstract The loss of instream wood can create a legacy of channel incision that is detrimental to habitat formation.
