Multi‐Marker Mitochondrial Analysis Reveals Genetic Diversity and Phylogenetic Relationships of Black Sea Sturgeons (Acipenseridae)

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Sturgeons are an important species due to their complex genetic structure and evolutionary characteristics. Unfortunately, they are threatened with extinction due to illegal and overfishing, as well as the loss of their natural habitats. In our work, we examine the genetic diversity of four sturgeon species that inhabit the Black Sea basin and its ...

Transition–Transversion Bias at the CYTB Gene Level in the Order Cypriniformes (Actinopterygii) as Evidence for the Influence of Metabolic Rate on Molecular Evolutionary Rate

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Families and subfamilies inhabiting temperate regions exhibit increasing transition frequencies and decreasing transversion frequencies with increasing genetic divergence, resulting in a pronounced transition–transversion bias. In contrast, tropical taxa show the opposite pattern, with elevated transversion frequencies and a markedly weaker bias.

Environmental DNA and Conventional Sampling Capture Complementary Patterns of Ichthyofaunal Diversity in the Selangor River Estuary, Malaysia

Environmental DNA, Volume 8, Issue 4, July‐August 2026.
Mangrove estuaries are a key ecosystem for coastal fishery resources, especially in developing nations such as Malaysia. Using identical sampling points and duration for both eDNA metabarcoding and conventional sampling, fish community analyses highlight shared and unique taxa, variable taxonomic resolution, and the complementarity of eDNA ...

Morphological Differences in Feeding and Digestive Organs, the Diversity of Intestinal Microorganisms, and Variations in Digestive Enzyme Activity Promote the Differentiation of Nutritional Niches in Schizothoracinae Species

Animals
The mechanisms of nutritional niche differentiation among sympatric Schizothoracinae fishes play an important role in their adaptive evolution and should be considered in conservation strategies.

Cyprinidae

Polyploid evolution in Cyprinidae. The achievement of evolutionary novelty is challenging due to the multitude of evolutionary pressures and the lengthy process of mutation and selection. On rare occasions, species hybridisation may result in fertile hybrids that exhibit an ecological benefit from the novel combination of genes and the subsequent ...

Cyprinidae A. d'Orbigny 1844

, 2020
4.7| Cyprinidae There are three species of Barbus distributed in the region. Barbus ciscaucasicus in northern parts of Georgia and Azerbaijan, B. cyri in the Kura and Aras drainage and B. rionicus in the Black Sea basin in the west Georgia. The recent study done by Levin, Gandlin, et al. (2019) has shown that Barbus goktschaicus does not differ from B.

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.

Fish Presence, but Not Hydrological Connectivity, Alters Amphibian and Zooplankton Communities in Kettle Lakes

Freshwater Biology, Volume 71, Issue 7, July 2026.
ABSTRACT Fishless lakes, which may harbour higher biodiversity than lakes with fish, are becoming increasingly rare due to fish introductions. Although the impacts of fish introduction are relatively well studied in high‐elevation fishless lakes, previous studies have mainly focused on a single invertebrate community or on a particular life stage of a ...
