Affordable de novo generation of fish mitogenomes using amplification‐free enrichment of mitochondrial DNA and deep sequencing of long fragments

Molecular Ecology Resources, Volume 23, Issue 4, Page 818-832, May 2023., 2023
Abstract Biomonitoring surveys make use of metabarcoding tools to describe the community composition. These studies match their sequencing results against public genomic databases to identify the species. However, mitochondrial genomic reference data are yet incomplete, only a few genes may be available, or the suitability of existing sequence data is ...

Does the loss of diadromy imply the loss of salinity tolerance? A gene expression study with replicate nondiadromous populations of Galaxias maculatus

Molecular Ecology, Volume 32, Issue 9, Page 2219-2233, May 2023., 2023
Abstract The recurrent colonization of freshwater habitats and subsequent loss of diadromy is a major ecological transition that has been reported in many ancestrally diadromous fishes. Such residency is often accompanied by a loss of tolerance to seawater.

INVENTARIO DE LARVAS DE PECES REGISTRADAS PARA EL CARIBE COLOMBIANO

Bulletin of Marine and Coastal Research, 2016
A taxonomic checklist of larval stages of fish species recorded in the Colombian Caribbean is presented, as a product of an extensive literature review of studies on the topic. Eighty five family records included in 21 orders, with a total of 129 species were found. In terms of composition, the order Perciformes has shown the highest number of families

Admixture and Selection Driven by El Niño–Southern Oscillation Events Shape the Genetic Structure of Octopus mimus–O. hubbsorum Complex Across the Humboldt and South Equatorial Current Transition Zone

Ecology and Evolution, Volume 16, Issue 9, September 2026.
Whole‐genome sequencing of the Octopus mimus–O. hubbsorum complex in the eastern Pacific identified two main genetic clades—northern warm‐water and southern cold‐water lineages—with a broad admixture zone during ENSO years where admixed individuals reflect both their genomic makeup and local environments.
