CLOFFAR - update 3 - supplement to Checklist of the Freshwater Fishes of Argentina [PDF]

, 2017
In May 2016 we have published the second update to CLOFFAR and in these few months a total of 22 changes have summed up. The total number of fishes known from the freshwaters of Argentina has increased to 538, caused by one new Hoplias and 13 first ...

Bony fish genomes: Status and gaps

Journal of Fish Biology, EarlyView.
Abstract Bony fish constitute an exceptionally species‐rich group of aquatic vertebrates, comprising more than 95% of all living fish. The adaptive processes on the diversity of environments they inhabit make them a highly diverse group from taxonomic, morphological and evolutionary standpoints.

Genomic data support the taxonomic validity of Middle American livebearers Poeciliopsis gracilis and Poeciliopsis pleurospilus (Cyprinodontiformes: Poeciliidae)

PLoS ONE, 2022
Poeciliopsis (Cyprinodontiformes: Poeciliidae) is a genus comprised of 25 species of freshwater fishes. Several well-known taxonomic uncertainties exist within the genus, especially in relation to the taxonomic status of Poeciliopsis pleurospilus and P ...

Developmental ecology of annual killifish Millerichthys robustus (Cyprinodontiformes: Cynolebiidae) [PDF]

Developmental Dynamics, 2017
AbstractPopulations of annual killifishes persist in temporary water bodies over the dry season through the expression of diapause in their drought‐resistant embryos. Environmental cues may influence expression of the diapause phenotype during embryonic incubation. Millerichthys robustus is the only annual killifish distributed in North America.

The evolution, distribution and diversity of endogenous circoviral elements in vertebrate genomes [PDF]

, 2018
Circoviruses (family Circoviridae) are small, non-enveloped viruses that have short, single-stranded DNA genomes. Circovirus sequences are frequently recovered in metagenomic investigations, indicating that these viruses are widespread, yet they remain ...

Unraveling Temporal Fish Diversity in a Neotropical Hydropower Reservoir: Comparing eDNA Metabarcoding to Traditional Fishing Methods

Environmental DNA, Volume 8, Issue 2, March/April 2026.
Comparing eDNA metabarcoding and gillnet surveys in a Neotropical reservoir, this study finds that eDNA detects greater species richness yet reveals distinct assemblage structures. The results underscore the value of integrating both methods to achieve comprehensive biodiversity monitoring in hydropower‐impacted ecosystems.

Global Patterns and Gaps in Research on Salinity Tolerance of Inland Fishes

Fish and Fisheries, Volume 27, Issue 2, Page 400-411, March 2026.
ABSTRACT Freshwater salinization is an emerging threat impacting approximately one‐third of the world's freshwater bodies. However, the salinity tolerance of many inland fishes remains understudied, despite being a crucial factor in determining species distributions and fitness.

The Geographical Variation of Colour Change in the Arabian Killifish (Aphaniops dispar Sensu Lato) From Freshwater and Marine Ecosystems

Ecology and Evolution, Volume 16, Issue 2, February 2026.
Animals that live in a wide range of environments possess plastic traits such as colour change, but most research has only looked at this within single populations. In this study, we tested four populations of the Arabian killifish from marine and freshwater ecosystems, examining how well they change colour against different backgrounds.
