MOLECULAR CLONING AND QUANTITATIVE mRNA EXPRESSION OF SOX9 GENE IN GONADAL DEVELOPMENTAL PERIOD OF HYPOATHERINA TSURUGAE

Journal of Experimental and Molecular Biology
Sox9 is a transcription factor of high mobility group (HMG) box family DNA binding domain. It plays a crucial role in gonadogenesis during embryonic developmental period. 1454 bp of sox9 mRNA transcript of Hypoatherina tsurugae (D. S.

Beyond Hard Parts: Metabarcoding Advances Dietary Resolution in Threatened Amazonian Elasmobranchs

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 5, May 2026.
ABSTRACT Elasmobranchs are highly vulnerable and are considered one of the most threatened vertebrates worldwide. Insights into diet can improve conservation measures. The bias of traditional morphological methods towards taxa with distinctive hard parts makes metabarcoding analysis a complementary tool to assess diet composition. Here, we analysed the

Evaluating the Potential for Citizen Science Divers to Monitor Fish Biodiversity Through Passive eDNA Collection

Environmental DNA, Volume 8, Issue 2, March/April 2026.
Passive capture of eDNA can be used as a tool for citizen scientist SCUBA divers to supplement visual surveys for marine species detection and is particularly useful for species that are rare or visually inaccessible to divers. ABSTRACT Environmental DNA (eDNA) marker gene sequencing, or metabarcoding, can be a powerful tool for monitoring marine ...

Taxonomic review of the genus Hypoatherina Schultz 1948 (Atheriniformes: Atherinidae) [PDF]

Ichthyological Research, 2014
The marine atherinid fishes of the genus Hypoatherina Schultz 1948 (Atherinidae: Atherinomorinae) were redefined from both morphological and molecular analyses, and eight of the ten included species were redescribed. In the molecular phylogeny, four regions of mitochondrial DNA were analyzed. The results of both trees of maximum likelihood and Bayesian

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.

Fine‐Scale Bioregionalization in a Complex Island System: A Freshwater Perspective From the Greater Antilles

Journal of Biogeography, Volume 53, Issue 1, January 2026.
ABSTRACT Aim The isolated nature of islands makes them particularly vulnerable to climate change. The freshwater fishes of the Greater Antilles remain understudied and are further threatened by habitat fragmentation and the introduction of exotic invasive species.
