New Mitochondrial Genomic Resources for the Freshwater Fishes of the Sanaga River (Cameroon). [PDF]
The Sanaga River Basin in Cameroon hosts a rich but poorly documented freshwater fish diversity. Here, we report the first complete mitochondrial genomes for nine species across four teleost orders, based on 39 specimens sequenced using Illumina NovaSeq.

Hybridization, Maternal Inheritance, and Evolutionary Time of Divergence of Endangered Species of <i>Hypancistrus</i> (Siluriformes: Loricariidae) in the Xingu River. [PDF]
We uncover recent hybridization dynamics among three endemic Hypancistrus species from the Xingu River, including the critically endangered H. zebra. Mitogenomic analyses reveal unidirectional maternal inheritance and recent evolutionary radiation (< 0.5 Ma), explaining their retained reproductive compatibility.

Precipitation Modulates the Impact of Human Activities on Riverine Food Webs Revealed by Environmental DNA. [PDF]
The effects of human activities on ecological networks are associated with climate, with increased precipitation weakening their negative impact. ABSTRACT The functionality of global rivers has been adversely affected by environmental pollution and habitat degradation.

The complete mitogenome of Pareuchiloglanis sichuanensis (Siluriformes: Sisoridae) [PDF]
Pareuchiloglanis sichuanensis is an endemic fish species in the upper reaches of the Yangtze River. In the present study, the complete mitochondrial genome of P. sichuanensis was analyzed. The mitochondrial genome, consisting of 16,774 base pairs (bp), included 13 protein-coding genes, 2 ribosomal RNAs, 22 transfer RNAs, and a non-coding control region.

Sperm of Doradidae (Teleostei: Siluriformes)
Spermatic characteristics were studied in 10 species representing several distinct groups within the catfish family Doradidae. Interestingly, different types of spermatogenesis, spermiogenesis and spermatozoa are correlated with intrafamilial groups previously proposed for Doradidae.
