Exploring the mitochondrial genomes and phylogenetic relationships of trans-Andean Bryconidae species (Actinopterygii: Ostariophysi: Characiformes). [PDF]

open access: yesPLoS One
Comparative mitogenomics and its evolutionary relationships within Bryconidae remains largely unexplored. To bridge this gap, this study assembled 15 mitogenomes from 11 Bryconidae species, including five newly sequenced.

Diel variation in insect‐dominated temperate pond soundscapes and guidelines for survey design

open access: yesFreshwater Biology, Volume 68, Issue 7, Page 1148-1160, July 2023., 2023
Abstract Passive acoustic monitoring has been used for decades as a non‐invasive tool for quantifying biodiversity in terrestrial and marine ecosystems. Recently, there has been increased interest in the potential for the method to survey freshwater biodiversity.

Genetic Diversity and Cryptic Species Identification of Genus Triplophysa from River Swat in Malakand Division, Khyber Pakhtunkhwa, Pakistan

open access: yesJournal of Applied Ichthyology, Volume 2023, Issue 1, 2023., 2023
Fish are cold blooded vertebrates’ identification on the bases of morphology is not more precise and required high taxonomic expertise therefore molecular identification is used as an alternative and more accurate technique for the identification of fishes.

Macroevolutionary consequences of karyotypic changes in the neotropical Serrasalmidae fishes (Ostariophysi, Characiformes) diversification

open access: yesGenetica, 2023
In the Neotropical region, one of the most diverse families of freshwater fishes is the monophyletic Serrasalmidae. Karyotypically, the family shows high diversity in chromosome numbers (2n = 54 to 64).
