First descriptions of copepodid stages, sexual dimorphism and intraspecific variability of Mesocletodes Sars, 1909 (Copepoda, Harpacticoida, Argestidae), including the description of a new species with broad abyssal distribution [PDF]

open access: yes, 2011
Mesocletodes Sars, 1909a encompasses 37 species to date. Initial evidence on intraspecific variability and sexual dimorphism has been verified for 77 specimens of Mesocletodes elmari sp. n. from various deep-sea regions, and ontogenetic development has

Phylogenomic analysis of Copepoda (Arthropoda, Crustacea) reveals unexpected similarities with earlier proposed morphological phylogenies

open access: yesBMC Evolutionary Biology, 2017
Copepods play a critical role in marine ecosystems but have been poorly investigated in phylogenetic studies. Morphological evidence supports the monophyly of copepods, whereas interordinal relationships continue to be debated.

Is it possible to simplify environmental monitoring? Approaches with zooplankton in a hydroelectric reservoir

open access: yesActa Limnologica Brasiliensia, 2017
Aim: In order to contribute to the knowledge about the simplification of biological surveys, this study evaluated the use of substitute groups, numeric and taxonomic resolution for the three main groups of zooplankton (cladocerans, copepods and rotifers)

Copepoda Parasitica [PDF]

open access: yesBijdragen tot de Dierkunde, 1927
Three females belonging to this species were obtained from the branchial cavity of Microcosmus exasperatus at Spanish Water, Curaçao, April 3, 1920. They were not fully grown but measured about 4.50 mm in length, and the large incubatory pouch was filled with minute eggs.

Ionotropic receptors signal host recognition in the salmon louse (Lepeophtheirus salmonis, Copepoda)

open access: yesPLoS ONE, 2017
A remarkable feature of many parasites is a high degree of host specificity but the mechanisms behind are poorly understood. A major challenge for parasites is to identify and infect a suitable host.

Concordance patterns in zooplankton assemblages in the UHE - Luís Eduardo Magalhães reservoir in the Mid-Tocantins river, Tocantins State, Brazil - doi: 10.4025/actascibiolsci.v33i2.7336

open access: yesActa Scientiarum: Biological Sciences, 2011
The goal of this study was to evaluate the concordance amongst three zooplankton groups (Rotifera, Cladocera, and Copepoda) and between the zooplankton groups and the environmental variables in the Luis Eduardo Magalhães reservoir, in the Mid-Tocantins ...
