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.

A phylogeny of Cichlidogyrus spp. (Monogenea, Dactylogyridea) clarifies a host-switch between fish families and reveals an adaptive component to attachment organ morphology of this parasite genus

Parasites & Vectors, 2015
Background Parasite switches to new host species are of fundamental scientific interest and may be considered an important speciation mechanism.

Sexual Dimorphism in Fin Size and Shape in Bluefin Killifish

Ecology and Evolution, Volume 16, Issue 2, February 2026.
This study shows very high levels of sexual dimorphism in dorsal and anal fin traits compared to other fins. Dorsal and anal fin traits are also correlated, such that individuals with large dorsal fins also have large anal fins. Together, this suggests strong sexual selection on these functionally integrated traits.

Diversity and Spatiotemporal Distribution of Fish in a Highland Lake in China Based on Environmental DNA Metabarcoding

Ecology and Evolution, Volume 16, Issue 2, February 2026.
We analyzed water samples from different seasons and locations in Erhai Lake to determine whether eDNA barcoding can effectively show the diversity of fish in such lakes. In the manuscript, we discuss our findings regarding the range of species found, their spatiotemporal distribution, and whether eDNA barcoding gave similar results to traditional ...

First record of the invasive Asian fish tapeworm Bothriocephalus acheilognathi in Honduras, Central America

Parasite, 2015
This paper provides the first report of the invasive Asian fish tapeworm, Bothriocephalus acheilognathi Yamaguti, 1934, in Honduras. The cestode was found in Profundulus portillorum (Cyprinodontiformes: Profundulidae), which represents a new host record,
