1. Salinity regulation of copepod egg production in a large microtidal estuary
ABSTRACT Salinity is a key variable for ecological processes in estuaries. Acartia tonsa is a typical estuarine copepod whose responses to salinity have been thoroughly studied in the laboratory. However, results cannot be extrapolated to the field, and formal comparisons between lab and field responses to salinity were not attempted. Here we compare lab-bas

2. Monitoring simplification in plankton communities using different ecological approaches
Resumo Objetivo Este estudo pretende responder: (i) as comunidades de fitoplâncton podem ser utilizadas como substitutos de comunidades zooplanctônicas? (ii) podemos utilizar abordagens ecológicas como grupos funcionais (FG) ou classificação morfofuncional (MBFG) como substitutos para espécies de fitoplâncton?; (iii) podemos usar grupos substitutos (

3. First record of Oithona attenuata Farran, 1913 (Crustacea: Copepoda) from Brazil
Abstract Here, we report the first record of the marine copepod Oithona attenuata Farran, 1913, in Brazil, from a costal station near Cabo Frio Island, Arraial do Cabo Municipality, Rio de Janeiro State. Specimens were found during March and May 2011 in zooplankton samples obtained from horizontal hauls using a plankton-net with a 100μm mesh size, and mouth

4. First record of the genus Anuropodione Bourdon, 1967 (Crustacea: Isopoda: Bopyridae) from the South Atlantic
Abstract The family Bopyridae Rafinesque, 1815 is comprised of parasitic isopods with a life cycle involving an intermediate host (copepod) and a definitive host (decapod crustacean). The genus Anuropodione Bourdon, 1967 occurs in all oceans and encompasses five species that are only known as parasites of squat lobsters belonging to the genus Munida Leach, 1

6. Description of the postembryonic stages of Boeckella poopoensis (Crustacea, Copepoda, Centropagidae)
ABSTRACT Boeckella poopoensis Marsh, 1906 is one of the most common copepods in the saline lakes of South America, where generally is the species that greater contributes to the zooplankton community biomass. Despite of its wide geographic distribution and ecological importance, the characteristics of the postembryonic stages are unknown, which prevents a de

7. Vertical distribution and structure of copepod (Arthropoda: Copepoda) assemblages in two different seasons down to 1,200 m in the tropical Southwestern Atlantic
ABSTRACT The vertical distribution of copepod assemblages, ascertained from the surface down to 1,200 m, was investigated during two sampling periods (rainy and dry seasons), at four depths, in the oligotrophic waters of the southwestern Atlantic Ocean. Total density, diversity, and richness differed among sampling depths. Copepod density decreased with dept

8. Gill parasites of fish from two estuaries in northeastern Brazil: new hosts and geographical records
ABSTRACT Parasites are important components of communities and constitute great part of the biological diversity found in ecosystems, providing valuable information about their hosts and the environment in which they live. However, despite its importance, parasitic diversity is still not well known in some regions of Brazil, especially with respect to fish p

9. Ergasilus turkayi n. sp. (Copepoda, Cyclopoida, Ergasilidae): a gill parasite of Serrasalmus hollandi Jégu, 2003 (Characiformes, Serrasalmidae) from the Paragua River, Bolivia
Abstract A new parasitic copepod species, Ergasilus turkayi n. sp., found on the gills of the Holland’s piranha, Serrasalmus hollandi Jégu, 2003, in the Paragua River, Bolivia, is described based on 10 adult females. The new species presents a triangular-shaped cephalothorax, spinules on interpodal plates and aesthetascs on antennule - two aesthetascs on

10. First report of deep-sea copepod Megacalanus princeps Wolfenden, 1904 (Calanoidea: Megacalanidae) from southwestern Atlantic
Abstract The deep-sea copepod Megacalanus princeps Wolfenden, 1904 was previously recorded from the northern and southeastern Atlantic, Indian and Pacific oceans, but not previously observed from southwestern Atlantic. Here we report its first occurrence in Brazilian waters. The current record increases the knowledge on the species distribution and on the de

11. Biology of Boeckella poopoensis Marsh, 1906 (Copepoda, Calanoida) in natural conditions in temporary saline lakes of the central Argentina
Boeckella poopoensis Marsh, 1906 is the dominant copepod in saline lakes from northern Patagonia to southern Peru. It is a tolerant species, which has been registered at salinities between 20 and 90 g.L-1, and is important because it integrates the diet of flamingos and fishes of commercial and sport interest. The aims of this study were to analyze the chara

12. Use of the copepod Oithona hebes as a bioencapsulator of essential fatty acids
ResumoAs vantagens do uso dos copépodos em aquicultura incluem a superioridade nutricional, alta digestibilidade e um amplo espectro de tamanhos, com a possibilidade de bioencapsular nutrientes, probióticos e medicamentos. O objetivo deste estudo foi comparar o efeito da alimentação de copépodos com uma dieta de microalgas e duas dietas inertes comercia
