Phylogenetic position of the Atlantic Gnomefish, Scombrops oculatus (Teleostei: Scombropidae), within the genus Scombrops, inferred from the sequences of complete mitochondrial genome and cytochrome c oxidase subunit I genes

open access: yesMitochondrial DNA. Part B. Resources, 2021
We determined the complete mitochondrial genome of the Atlantic Gnomefish, Scombrops oculatus (Scombropidae). The total length of mitochondrial DNA (mtDNA) was 16,515 bp and included 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNA genes,

Two new species of Trichomycterus (Siluriformes: Trichomycteridae) from the Rio Itabapoana Basin, south-eastern Brazil

open access: yesEuropean Journal of Taxonomy
Streams in the Atlantic Forest of Brazil are home to a great diversity of endemic freshwater fishes, but some fish groups are still poorly known. In the last 22 years, our field inventories have recorded some species of the mountain catfish genus ...

Integrative sperm DNA methylation and miRomics analysis highlights interaction of two epigenetic patterns of pseudomale inheritance in teleost

open access: yesFrontiers in Marine Science, 2022
Proper DNA methylation in spermatozoa is essential for the normal development of fertilized embryos through gene expression regulation. Abnormal sperm DNA methylation is associated with male fertility impairment, offspring quality decline, and disease ...

A case of intersex occurrence in Steindachneridion parahybae (Steindachner, 1877) (Siluriformes: Pimelodidae) under captivity condition: A cytogenetic and morphological study [PDF]

open access: yes, 2016
Poco se sabe sobre la biología reproductiva de Steindachneridion parahybae , una especie de teleósteo gonocorístico en peligro de extinción que habita la cuenca del río Paraíba do Sul y en éste trabajo se describe por primera vez la aparición de ...

Calcium Metabolism of Teleosts [PDF]

open access: yesAmerican Zoologist, 1967
The osseous tissues of modern bony fishes are usually classified as cellular or acellular bone. The latter lacks osteocytes; the former is restricted to individual families within the Clupeiformes and Scopeliformes. Many fishes can take up calcium actively from their environment and apparently can store considerable amounts of calcium in sites other ...

Peculiar Expression of CD3-Epsilon in Kidney of Ginbuna Crucian Carp

open access: yesFrontiers in Immunology, 2018
TCR/CD3 complex is composed of the disulfide-linked TCR-αβ heterodimer that recognizes the antigen as a peptide presented by the MHC, and non-covalently paired CD3γε- and δε-chains together with disulfide-linked ζ-chain homodimers.

A direct cerebello-telencephalic projection in an electrosensory mormyrid fish [PDF]

open access: yes, 1990
After injections of the posterior part of the lateral zone of the area dorsalis telencephali (Dlp) with either horseradish peroxidase or the newly available carbocyanine dye DiI, efferent cells were labeled in the valvula cerebelli of the mormyrid fish ...

Mitochondria in teleost spermatozoa

open access: yesMitochondrion, 2017
There is an extraordinary diversity of reproductive modes in teleost and this variability is related to the phylogenetic relationships and adaption to very different biotopes. As in all vertebrates, sperm is produced as the end product of the process of spermatogenesis, and regarding teleost the spermatozoa lack an acrosome in almost all species and ...
