Genetic variability and population structure of Osteoglossum bicirrhosum (Osteoglossiformes: Osteoglossidae) in the Amazon basin [PDF]
Neotropical IchthyologyThis study tested the hypothesis that the silver arowana from different rivers in the Amazon basin is genetically structured, thus requiring differentiated management strategies to maintain stocks and continue economic activities. Such activities include

The Complete Genome Sequences of 38 Species of Elephantfishes (Mormyridae, Osteoglossiformes). [PDF]
Biodivers Genomes, 2022 We present the complete genome sequences of 38 species of elephantfishes from 20 genera. Illumina sequencing was performed on genetic material from single wild-caught individuals. The reads were assembled using a de novo method followed by a finishing step. The raw and assembled data is publicly available via Genbank.

Sex Differentiation and Long-Distance Gene Flow in the Elusive Antarctic Fish <i>Aethotaxis mitopteryx</i>. [PDF]
Ecol EvolThis genetic study of a rare Antarctic fish, the longfin icedevil (Aethotaxis mitopteryx) investigates population connectivity across the Weddel Sea, revealing little to no differentiation even over vast geographic distances. Unexpectedly, the strongest genetic differentiation is instead observed between male and female fishes, which suggests a ...
