The mitochondrial genome of clearhead icefish Protosalanx chinensis (Salmoniformes: Salangidae) [PDF]

Mitochondrial DNA. Part B. Resources, 2018
The complete mitochondrial genome of Protosalanx chinensis was determined to be 16,879 bp in length. It consists of 13 protein-coding genes, 22 tRNAs, 2 ribosomal RNAs, and a control region.

Origin and dispersal of the chars of genus Salvelinus (Salmonidae, Salmoniformes)

Известия ТИНРО
A new approach to the problem of origin and dispersal of genus Salvelinus is proposed, based on analysis of their ecology and reproductive biology forming in the process of climatic and geological evolution of the Earth.

The subunit composition of the mammalian Mediator complex is not conserved in all vertebrates: Insights from evolutionary plasticity of fish genomes. [PDF]

Protein Sci
Abstract The Mediator complex is an indispensable, multi‐subunit protein transcriptional coactivator with a central role in gene expression in Eukaryotes. Among vertebrates, its molecular structure and subunit composition are well‐known only for mammals.

Turning Red to Green Repeatedly: Ancestral LWS Duplications Drive Convergent Visual Tuning in Teleost Fishes. [PDF]

Mol Ecol
ABSTRACT Photopigments, formed by an opsin protein bound to a light‐sensitive chromophore, underlie vertebrate vision. Long‐wavelength–sensitive (LWS) opsins mediate red‐light detection, and most teleosts retain a single functional LWS1. A shorter‐shifted green‐sensitive paralog (LWS2) is found only in a few lineages.

Complete Mitochondrial Genome of <i>Gyrodactylus nigeri</i> (Platyhelminthes: Monogenea). [PDF]

Ecol Evol
The fish Yunnanilus niger is the host of Gyrodactylus nigeri. The mitochondrial genome of G. nigeri is 14,903 bp in length. Phylogenetic analyses indicated that this species belonged to the genus Gyrodactylus and Gyrodactylidae forms an independent monophyletic clade within Gyrodactylidea.

Opportunistic Feeding and Parasite Assemblages in Sei Whales (<i>Balaenoptera borealis</i>) From Southern Chile Revealed by DNA Metabarcoding. [PDF]

Ecol Evol
This study represents the first metabarcoding‐based description of prey composition and parasite‐associated taxa in stranded sei whales from southern South America. ABSTRACT Balaenopterid whales are major consumers in pelagic ecosystems and play a fundamental role in marine food webs.

Utilizing Environmental DNA Metabarcoding to Assess Fish-Based Food Resources in Key Foraging Areas of the Black Stork. [PDF]

Ecol Evol
This study employed environmental DNA (eDNA) to assess fish‐based food resources in key foraging areas of the Black Stork (Ciconia nigra)—Zhanghe Canyon and Qixi River National Wetland Parks in Henan, China. Results show that the main prey in these habitats are fish from the orders Siluriformes, Cypriniformes, and Perciformes, with no significant ...

Dietary modulation of antimicrobial peptides (HAMP and LEAP2) in Chinook salmon (Oncorhynchus tshawytscha) fed a phytobiotic functional diet: Integrated genomic characterisation and tissue-specific expression. [PDF]

J Fish Biol
Abstract Antimicrobial peptides (AMPs) are key components of the innate immune system in fish, providing rapid protection against microbial pathogens. Among these, the liver‐expressed antimicrobial peptides (LEAPs), comprising LEAP‐1 (hepcidin; HAMP) and LEAP‐2, play central roles in host defence and iron regulation.

Species Determination Within the Felidae Family Using mtDNA Minibarcoding. [PDF]

Anim Genet
ABSTRACT Wildlife forensic analysis frequently deals with highly degraded DNA samples, including those from tanned hides, processed products of traditional Chinese medicine, and specimens stored in preservation fluids. These samples present significant challenges for traditional DNA barcoding due to the difficulty of amplifying sufficiently long DNA ...

FishMitoCleaner: Automated Stop Codon Processing and Quality Control of Fish Mitochondrial Protein-Coding Sequences. [PDF]

Ecol Evol
FishMitoCleaner automates quality control of fish mitochondrial protein‐coding sequences, correctly handling both complete and incomplete stop codons while protecting terminal TGA codons as tryptophan residues. This tool requires no programming expertise and produces analysis‐ready sequences in a single command, resolving common errors that bias ...
