DNA barcoding of North American freshwater copepods (Diaptomidae and Cyclopoida): an overview after 20 years with emphasis in the Mexican fauna, the transition between the Nearctic and Neotropics [PDF]

PeerJ
Background In 2003, Paul Hebert proposed DNA barcoding, based on the first half of a standardized gene, the Cytochrome c Oxidase subunit I (COI), to identify animals.

Uncovering Hidden Diversity: Three New Species of the Keratella Genus (Rotifera, Monogononta, Brachionidae) of High Altitude Water Systems from Central Mexico

Diversity, 2021
The correct identification of species is an essential step before any study on biodiversity, ecology or genetics. Keratella is a genus with a predominantly temperate distribution and with several species being endemics or restricted geographically.

Ocean Sciences Perspectives on Integrated, Coordinated, Open, Networked (ICON) Science

Earth and Space Science, Volume 9, Issue 9, September 2022., 2022
Abstract This article is composed of three independent commentaries of how “Integrated, Coordinated, Open, and Networked” (ICON), as well as “Findable, Accessible, Interoperable, and Reusable” (FAIR; under the umbrella of “Open” from ICON), principles are currently embedded in ocean sciences, and what are the opportunities and challenges by adopting ...

Shifts in the seasonal trophic ecology of larvae and juveniles of European hake (Merluccius merluccius): From the Galician upwelling system (NW Spain)

Fisheries Oceanography, Volume 31, Issue 5, Page 539-553, September 2022., 2022
Abstract The trophic ecology of European hake (Merluccius merluccius) larvae and early‐juveniles from the Iberian shelf off Galicia (NW Spain) are assessed by means of stable isotopes (SIA) and nutritional condition in conjunction with hydrobiological variations observed during the winter and summer season of 2012.

Reverse diel vertical movements of oceanic manta rays off the northern coast of Peru and implications for conservation

Ecological Solutions and Evidence, Volume 2, Issue 1, January–March 2021., 2021
Manta photo supplied by Stephanie Venables Recovered satellite tags revealed fine‐scale reverse diel vertical movements of oceanic manta rays in the coastal and highly stratified waters of northern Peru. Movements appeared to be driven by a strategy of foraging and thermal recovery.

Habitat light sets the boundaries for the rapid evolution of cichlid fish vision, while sexual selection can tune it within those limits

Molecular Ecology, Volume 29, Issue 8, Page 1476-1493, April 2020., 2020
Abstract Cichlid fishes' famous diversity in body coloration is accompanied by a highly diverse and complex visual system. Although cichlids possess an unusually high number of seven cone opsin genes, they express only a subset of these during their ontogeny, accounting for their astonishing interspecific variation in visual sensitivities. Much of this

Planktonic rotifers of a saline-lowland river : The Salado River (Argentina) [PDF]

, 2002
Seasonal samples of zooplankton were taken during 1997-1999 at fifteen stations in the Salado River basin, and analysed in order to study the rotifer fauna. Spatio-temporal changes in the rotifer plankton composition were examined in the main channel and
