Ocurrence record of Pontella marplatensis copepod in Arraial do Cabo RJ – Brazil

Abstract

Registro de ocorrência do copépode Pontella marplatensis em Arraial do Cabo RJ-Brasil. Esta comunicação científica representa o registro de copépode Pontella marplatensis Ramirez 1966, na estação próxima à Ilha de Cabo Frio localizado entre as coordenadas 22°59'86"S 42°00'28"W Arraial do Cabo RJ-Brasil. Esta espécie de copépode marinho ocorreu na amostra de zooplâncton no dia 15 de Setembro de 2010, obtido através de arrasto horizontal com rede de 100µm e 40cm de diâmetro.

First record of Oithona attenuata Farran, 1913 (Crustacea: Copepoda) from Brazil

“…Oithona attenuata is recorded here for the first time off Brazil, even though several studies had previously been conducted in the same place (Valentin, 1984;Dias and Araujo, 2006;Dias et al, 2010;Rosa and Monteiro-Ribas, 2012;Rosa et al, 2016). Its absence in plankton samples over the last 30 years leads us to suggest that this species was brought to Brazilian waters as an exotic species.…”

“…Exotic copepods that have been successfully introduced off the Brazilian coast include: Temora turbinata (Dana, 1849), Pseudodiaptomus trihamatus Wright, 1937, Apocyclops borneoensis Lindberg, 1954, Paracyclopina longifurca (Sewell, 1924, Phyllopodopsyllus setouchiensis Kitazima, 1981. Furthermore, another exotic species, Pontella marplatensis Ramirez, 1966, was also recorded for the first time in the same region off Arraial do Cabo in September 2010 (Rosa and Monteiro-Ribas, 2012). It was described from the Argentine Sea (Mar del Plata) by Ramirez (1966) and had since also been found off Texas (Gulf of Mexico) (Waggett and Buskey, 2008).…”

Tracking of spatial changes in the structure of the zooplankton community according to multiple abiotic factors along a hypersaline lagoon

“…They live for a short period and only to reproduce (Suárez-Morales and Palomares-García, 1995). This is the first record of this order in the region of Cabo Frio (Valentin et al, 1987;Monteiro-Ribas and Mureb, 1991;Rosa et al, 2016b;Rosa and Monteiro-Ribas, 2012;Rosa et al, 2019).…”
