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.

Análise morfométrica das células de cloro de Poecilia vivípara expostas a frações da folha e da casca do caule de Caryocar brasiliensis - DOI: 10.4025/actascibiolsci.v25i1.2107

Acta Scientiarum: Biological Sciences, 2008
Frações da folha e casca de pequi (Caryocar brasiliensis), testadas como moluscicidas, combateram o hospedeiro intermedário da esquistossomose. O nicho ecológico desse molusco está associado a mananciais de água.

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.

Otolith‐based species identification in the killifish Aphaniops (Teleostei; Cyprinodontiformes; Aphaniidae) using both morphometry and wavelet analysis

Acta Zoologica
The killifish genus Aphaniops consists of nine species distributed in Eastern Africa and the Middle East. However, distinguishing these species from each other based on morphological traits is challenging.

Rivulids (Rivulidae: Cyprinodontiformes) of Bolivia: knowledge status and updated inventory

Neotropical Hydrobiology and Aquatic Conservation, 2023
The state of knowledge regarding rivulids in Bolivia is still limited and has some significant gaps. With the aim of synthesizing and systematizing the available information, which is often scattered, a monographic review is presented that examines the ...

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.

Two new genera of killifish (Cyprinodontiformes) from the Middle Miocene of the Bugojno Basin, Bosnia and Herzegovina: insights into the lost diversity of Valenciidae

Journal of Systematic Palaeontology
Present-day killifishes (Cyprinodontiformes, toothcarps), known for their diversity and ecological adaptability, are represented in Eurasia by two families that each have their own taxonomic diversity, namely the diverse Aphaniidae (eight genera, > 40 ...

Genetic diversity of the species Cnesterodon hypselurus (Cyprinodontiformes: Poeciliidae) in Cinzas River basin: new record and headwater capture evidences

Neotropical Ichthyology, 2023
Cnesterodon hypselurus is a small fish that has a restricted distribution in southern Brazil, including headwaters of the Tibagi and Itararé river basins (Upper Paraná River). This study reported C.

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.
