Exposure to the Oestrogenic Pollutant 17α‐Ethinyl Estradiol (EE2) Does Not Alter the Behaviour of a Coastal Marine Fish, Cristiceps australis

open access: yesEthology, Volume 132, Issue 4, Page 295-304, April 2026.
Environmental contamination with the synthetic estrogen 17α‐ethinyl estradiol (EE2) is widespread in coastal ecosystems, yet behavioural effects in marine fishes remain poorly understood. We exposed southern crested weedfish (Cristiceps australis) to low and high EE2 concentrations for 14 days and assessed boldness and anxiety using a refuge‐use assay.

The complete mitochondrial genome of Cyclocheilichthys enoplos (Teleostei, Cyprinidae)

open access: yesMitochondrial DNA. Part B. Resources, 2018
Here, we reported the complete mitochondrial genome of Cyclocheilichthys enoplos, which is widely distributed in Southeast Asia. The genome was 16,579 bp in length, containing 2 ribosomal RNA genes, 22 tRNA genes, a non-coding control region (D-loop ...

PhyloRef: A Semi‐Automated Workflow for eDNA Reference Database Curation via Phylogenetic Anomaly Detection

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
PhyloRef processes complete mitochondrial genomes with optional multi‐gene concatenation to flag three categories of phylogenetic anomalies based on tree topology and annotates ambiguous sequences with “similar_to=” labels. The workflow successfully curated 7600+ chondrichthyan and actinopterygian sequences from NCBI, identifying and removing 410 ...

A Multi‐Taxa Approach to Estuarine Biomonitoring: Assessing Vertebrate Biodiversity and Ecological Continuity Using Environmental DNA Metabarcoding in the Rance River (Brittany, France)

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
We applied eDNA metabarcoding to assess vertebrate diversity in the Rance Estuary, France, across five stations spanning marine to freshwater environments, including areas upstream and downstream of a tidal power plant dam. A total of 124 vertebrate MOTUs were detected, with community composition reflecting the estuarine gradient and species turnover ...

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.

Isolation, Antibiogram and Factors Associated With Staphylococcus aureus From Fish at the Landing Site and Selected Restaurants in Central Gondar, Ethiopia: One Health Approach

open access: yesVeterinary Medicine and Science, Volume 12, Issue 2, March 2026.
This study identified Staphylococcus aureus in 26% of fish, hand and knife samples from Gondar, Ethiopia, with high multidrug resistance. Findings highlight unsafe handling practices and recommend improved hygiene, regular monitoring and targeted antibiotic use to reduce contamination risks and protect public health through a One Health approach ...

Applying Generalized Joint Attribute Modeling to Select Local Indicator Fish Species for River Management

open access: yesEcological Research, Volume 41, Issue 2, March 2026.
We propose an approach that employs generalized joint attribute modeling (GJAM) to select local indicator species. We examined whether GJAM has the potential to select local indicator species using data on water environmental factors and fish densities in two rivers in Kanagawa Prefecture, Japan. ABSTRACT To protect local ecosystem and biodiversity, it

One number to rule them all: The Wildlife Sperm Index for standardized gamete assessment

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 3, Page 705-717, March 2026.
Abstract In wildlife conservation, breeding programmes focused on reintroduction are critical to recovering endangered species. Assisted reproductive technologies (ARTs) and biobanking play pivotal roles in these efforts but depend on high‐quality gametes.

Ligula intestinalis (Cestoda: Pseudophyllidea): an ideal fish-metazoan parasite model? [PDF]

open access: yes, 2010
Since its use as a model to study metazoan parasite culture and in vitro development, the plerocercoid of the tapeworm, Ligula intestinalis, has served as a useful scientific tool to study a range of biological factors, particularly within its fish ...
