The context dependency of fish‐habitat associations in separated karst ecoregions

Ecology and Evolution, 2023
Fish populations may be isolated via natural conditions in geographically separated ecoregions. Although reconnecting these populations is not a management goal, we need to understand how these populations persist across landscapes to develop meaningful ...

Stayin' alive: Strategies to reduce predation on target species are context dependent

Ecosphere, Volume 17, Issue 8, August 2026.
Abstract Restoration and conservation efforts often aim to reduce predation, particularly by reducing interactions with nonnative predators in heavily disturbed and invaded ecosystems. For Chinook salmon Oncorhynchus tshawytscha, a highly valued but declining fishery, potentially useful freshwater rearing habitat restoration strategies may include ...

Increasing artificial light at night enhances salmonid predator foraging efficiency in an urbanized lake

Limnology and Oceanography, Volume 71, Issue 8, August 2026.
Abstract Artificial light at night (ALAN) poses a threat to ecosystems globally. It includes both direct and indirect light, or skyglow, which occurs when ALAN scatters in the atmosphere, extending beyond its original source. We analyzed ALAN trends in Lake Washington, WA, from 2014 to 2023 using Visible Infrared Imaging Radiometer Suite (VIIRS ...

Swimming Upriver? Exploring the Sources of Freshwater and Marine Fish in Military Diet in Sixteenth‐ to Nineteenth‐Century Northeastern North America

International Journal of Osteoarchaeology, Volume 36, Issue 4, Page 984-1012, July/August 2026.
ABSTRACT Atlantic cod were caught in large numbers and shipped from fishing stations in North America to Europe and the Caribbean, and this has been frequently studied zooarchaeologically; however, the exchange of cod and other fish into interior North America has received less study.

Worldwide Invasions of Centrarchidae: The Dark Side of the Sunfish Family

Fish and Fisheries, Volume 27, Issue 4, Page 781-812, July 2026.
ABSTRACT Freshwater fish invasions are major drivers of global ecological change, disrupting native biodiversity and ecosystem functions. However, many invasive fish hold significant socioeconomic value, resulting in conflict over their management. Centrarchidae, which are globally distributed and are important for sportfishing and aquaculture, are now

Potential threats to smallmouth bass (Micropterus dolomieu) in the Juniata River Basin, Pennsylvania, USA

Journal of Freshwater Ecology, 2019
The Susquehanna River basin is one of the largest and most diverse watersheds in the northeastern United States, however, its historically renowned Micropterus dolomieu (smallmouth bass–SMB) fishery has been in decline since the mid-2000s.

Diet of juvenile skipjack herring Alosa chrysochloris: Ontogenetic shifts, predator–prey size ratios and mouth gape allometry

Journal of Fish Biology, Volume 109, Issue 1, Page 384-399, July 2026.
Abstract The skipjack herring Alosa chrysochloris inhabits Gulf of Mexico drainages, primarily the Mississippi River Basin, and estuarine environments in the Gulf of Mexico. The trophic ecology of the skipjack herring is poorly understood, therefore we quantified the length, mouth gape and gut contents of juvenile skipjack herring from the Mississippi ...

Seasonal movements of adult Gizzard Shad Dorosoma cepedianum in a Missouri River reservoir

Journal of Freshwater Ecology
Gizzard Shad Dorosoma cepedianum are important for nutrient cycling and can affect water clarity, plankton densities, and fish production levels. Gizzard Shad can also be crucial prey fish for recreationally important species such as Walleye Sander ...

Phylogenetic and Environmental Insights Into the Biogeography of the Western Blacknose Dace, Rhinichthys obtusus

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Pleistocene glaciations have shaped freshwater fish evolution and distribution patterns across North America. This study investigated the phylogeographical history of the Western Blacknose Dace (Rhinichthys obtusus) using mitochondrial genomic data, revealing three major clades that diverged 2–1.5 million years ago during Pleistocene glaciations when ...
