Prevalence and Implications of “Must‐Kill” Angling Regulations for the Management of Invasive Fishes

open access: yesFisheries Management and Ecology, Volume 33, Issue 2, Page 260-270, April 2026.
ABSTRACT Freshwater biodiversity is increasingly threatened by invasive species, which can disrupt native fish populations and the fisheries they support. Must‐kill regulations, which prohibit the live release of invasive fish caught by recreational anglers, are a management strategy that can be implemented to limit the negative effects of invasive ...

Comparing Aquatic Environmental DNA Collection Methods Across a Diel Cycle in a Lotic System

open access: yesEnvironmental DNA, Volume 8, Issue 2, March/April 2026.
Water samples were collected over 25 h from the Tangipahoa River, Louisiana, using active and passive environmental DNA methods to detect fish assemblages. Active sampling involved collecting water samples at hourly intervals for 25 h, whereas passive sampling deployed a stationary filter for 25 h.

Freshwater amphibians and squamates from Villeveyrac (lower Campanian; Hérault, France): palaeodiversity, palaeoenvironment and implications for the Late Cretaceous palaeobiogeography of the European herpetofauna

open access: yesPapers in Palaeontology, Volume 12, Issue 1, January/February 2026.
Abstract The Late Cretaceous witnessed numerous transgression–regression sequences and the onset of a global cooling phase at the start of the Campanian. In the European archipelago, these environmental changes, combined with active plate tectonics, facilitated the formation of ephemeral land bridges that served as dispersal routes for a variety of ...

Comparative Diets of Invasive Blue Catfish: Differences Across Rivers and Ontogenetic Stages

open access: yesEcology of Freshwater Fish, Volume 34, Issue 2, April 2025.
ABSTRACT Blue Catfish (Ictalurus furcatus) are an invasive species with expanding populations in freshwater systems, posing significant ecological challenges to native fauna. To assess their potential impacts in diverse aquatic ecosystems, we examined and compared the diets of non‐native Blue Catfish from four rivers in Georgia, USA, two of which drain

Advancing Environmental Flows Science: Hindcasting and Forecasting Flow–Ecology Relationships

open access: yesFisheries, Volume 49, Issue 8, Page 353-368, August 2024.
To advance current environmental flow standards in Texas, we developed field, laboratory, and analytical methods to model recruitment dynamics of indicator species selected to cover a range of population responses to flow variation. Preliminary investigations were conducted in three central Texas river basins to evaluate the feasibility of these ...

Determination of optimal prey for rearing tropical gar Atractosteus tropicus (Lepisosteiformes: Lepisosteidae)

open access: yesRevista de Biología Tropical, 2018
Larval feeding studies of both ornamental and consumable fish species are important for formulating successful management, and culture strategies for conservation purposes. In the present study, we evaluated prey selectivity for the tropical gar Atractosteus tropicus in the larval stage (first 8 weeks) using the zooplankton Artemia fransiscana, Daphnia

Freshwater megafauna shape ecosystems and facilitate restoration

open access: yesBiological Reviews, Volume 99, Issue 4, Page 1141-1163, August 2024.
ABSTRACT Freshwater megafauna, such as sturgeons, giant catfishes, river dolphins, hippopotami, crocodylians, large turtles, and giant salamanders, have experienced severe population declines and range contractions worldwide. Although there is an increasing number of studies investigating the causes of megafauna losses in fresh waters, little attention
