Marine zooplankton studies in Brazil: a brief evaluation and perspectives

“…up to 4 cruises in a 1-year interval (e.g., Lopes et al 1999). Studies on zooplankton temporal variation which included monthly or quarterly sampling schemes were done at fixed stations close to the shore, and dealt with restricted taxonomic groups (Milstein 1979, Pinese 1982, Moreira et al 1983). In addition, most of those studies did not analyze important environmental covariables, such as chlorophyll-a concentration.…”

Grazing by the Copepod Parvocalanus crassirostris on Picochlorum sp. at Harmful Bloom Densities and the Role of Particle Size

“…The grazer used in this study was P. crassirostris, which was the dominant herbivorous copepod in the region of the superbloom according to a 3-years record of mesozooplanktonic abundances (Sweat et al, unpublished data). It is a small (∼2 mm long), holoplanktonic, calanoid copepod that dwells in the upper 6-20 m of tropical and subtropical estuarine, coastal, and oceanic waters (Milstein, 1979;Turner and Dagg, 1983;Wong et al, 1993;Tang et al, 1994;Almeida et al, 2012;Sun et al, 2012;Liu et al, 2013). It is common for this species and other calanoid copepods to reside permanently in the mid-to upper water column (Ma and Johnson, 2017), where they feed on microalgae and nanoplankton.…”

“…It is common for this species and other calanoid copepods to reside permanently in the mid-to upper water column (Ma and Johnson, 2017), where they feed on microalgae and nanoplankton. These cosmopolitan copepods have been shown to tolerate a wide range of temperatures (15-31 • C), salinities (20-37), and eutrophic or turbid conditions (Milstein, 1979;Wong et al, 1993;Almeida et al, 2012). Paracalanus crassirostris mainly grazes on nanophytoplankton (Calbet et al, 2000) and is a globally important mesozooplanktonic grazer.…”

Variação temporal e crescimento do zooplâncton no litoral norte de São Paulo, com ênfase em estágios imaturos de copépodes

“…Flamengo sobre a estrutura e variação temporal da comunidade zooplanctônica, pois outros autores focaram seus estudos em uma única espécie (Milstein, 1979;Pinese, 1983 e 300 µm foi empregada por outros autores (Lopes, 1997;Crété, 2006e Rimoldi, 2008. A preferência por utilização de redes com aberturas de malha superiores a 100 µm gerou como consequência a lacuna de conhecimento sobre as menores classes de tamanho do zooplâncton para a região.…”
