Fish Community Composition Revealed by eDNA Metabarcoding in Mangrove‐Associated Lagoons of Negombo and Puttalam, Sri Lanka

open access: yesEnvironmental DNA, Volume 8, Issue 5, September‐October 2026.
eDNA metabarcoding revealed distinct fish community composition between Negombo and Puttalam lagoons, with richness broadly comparable to conventional surveys. The approach detected diverse taxa, including cryptic taxa, demonstrating its value as a complementary tool for biodiversity monitoring in Sri Lanka's mangrove‐associated lagoons.

Morphological and Histometric Alterations in Gonadal and Neural Tissues of Native and Non‐Native Fishes From the Lower Doce River Basin in Southeastern Brazil

open access: yesAnatomia, Histologia, Embryologia, Volume 55, Issue 5, September 2026.
ABSTRACT The ichthyofauna of the lower Doce River basin has been exposed to multiple anthropogenic stressors. Among these, the collapse of the Fundão mining tailings dam in Mariana, Minas Gerais, Brazil, in 2015 resulted in massive fish mortality and widespread contamination of aquatic environments.

New records of Gerromorpha (Insecta: Hemiptera: Heteroptera) from Costa Rica [PDF]

open access: yesCheck List, 2014
The Gerromorpha from Costa Rica are poorly studied, except the Gerridae. Aiming to fill this gap, specimens collected across the country were examined. Lipogomphus leucostictus, Hydrometra alloiona, H. australis, H.

Chromosomes of five species of sea-skater (Gerridae-Heteroptera) [PDF]

open access: yesGenetica, 1983
We report here the first chromosome numbers for sea-skaters. Meiotic metaphase figures were obtained from the testes of three littoral species: Asclepios shiranui, Halobates flaviventris and H. robustus and two pelagic species: H. germanus and H. micans.

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

open access: yesEnvironmental 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 ...
