Herbivorous copepods with emphasis on dynamic Paracalanus quasimodo in an upwelling region

Abstract: Coastal upwelling is known to transfer the nutrientrich water from the deep ocean to the surface, which benefits primary production and consequently increases local organic production. Cabo Frio is favored by the phenomenon and copepods are one of the groups most benefited. According to the results presented here, the higher abundances of Pacalanus quasimodo relative to other species are due to its rapid response to upwelling-dependent blooms. Therefore this study aims to assess the herbivory and dynamics of m… Show more

“…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.…”

“…The entire field and laboratory procedure was performed with the assistance of the Instituto de Estudos do Mar Almirante Moreira (IEAPM). More details of the copepod assemblage can be found in the work by Rosa et al (2016).…”

“…A low number of taxa was found during the study (Copepod, Pteropods [Order Thecosomata], Cirripedia larvae, Decapoda, and Polychaeta), when compared to past data from regions near the Araruama lagoon (Arraial do Cabo) (Rosa et al, 2016b). A previous study also found only three copepod genera (Coutinho et al, 1999).…”

“…These peaks may be related to peaks in phytoplankton abundance because, as mentioned by Souza et al (2003), phytoplankton density is highest in the Araruama lagoon when the salinity is at its lowest. Studies with zooplankton have shown that when phytoplankton peaks are accentuated, the greater food availability consequently leads to an increase in the density of zooplankton (Fernandes et al, 2012;Highfield and Eloire, 2010;Rosa et al, 2016b).…”
