Dinophysiales (Dinophyceae) no extremo Sul do Brasil (inverno de 2005, verão de 2007)

Abstract

Abstract:The dinoflagellates of the Dinophysiales order are a morphologically diverse and ecologically heterogeneous group that includes autotrophic, mixotrophic and heterotrophic species and others containing endosymbionts or phycotoxin producers. In this research Dinophysis, Ornithocercus, Histioneis and Amphisolenia species have been identified in both coastal and oceanic waters of the Southern region of Brazil next to Santa Marta Grande Cape, SC and Albardão-Chuí, RS. Vertical hauls were performed with plankton nets (20 µm) on board of the R. V. Atlântico Sul at 33 oceanographic stations sampled in August/September 2005 (Winter) and February 2007 (Summer). The plankton was fixed with formaldehyde (4%) and analyzed with the help of an inverted microscope. A total of 43 Dinophysiales species were identified, most of them widely distributed in the coastal, continental and oceanic areas such as

Dinoflagellates in tropical estuarine waters from the Maraú River, Camamu Bay, northeastern Brazil

“…However, the majority of these studies is concentrated in the southern and southeastern coastal regions (e.g. Rosa and Buselato 1981;Kremer and Rosa 1983;Schmitt and Proença 2000;Islabão 2008;Mello et al 2010;Tavares et al 2009;Alves et al 2010;Haraguchi and Odebrecht 2010;Haraguchi 2010;Pedroso 2010;Islabão and Odebrecht 2011;Mafra et al 2014Mafra et al , 2015. On the northeast Brazilian coast, most of the studies were made in the state of Pernambuco and focused on the ecology of the phytoplankton community (e.g.…”

The composition and new records of micro- and mesophytoplankton near the Vitória-Trindade Seamount Chain

“…Three slides were observed for each sample using transect methodology under 100x magnification. In sequence, these taxa were identified with the appropriate bibliography (Kofoid 1905, Cupp 1943, Wood 1954, Abé 1967a, b, Balech 1967, 1971, 1979, Hallegraeff 1987, Balech 1988, Hernández-Becerril 1991, Fernández & García 1998, Botes 2002, Polat & Koray 2002, Gómez 2005, Koening & Lira 2005, Tenenbaum et al 2006, Haraguchi & Odebrecht 2007, Islabão & Odebrecht 2011, Garcia & Odebrecht 2012, Okolodkov 2014.…”

“…Subsequently, the search focused on phytoplankton species already reported in marine waters of Brazil, with the aim of finding new records (Koening & Lira 2005, Procopiak et al 2006, Tenenbaum et al 2006, Haraguchi & Odebrecht, 2007, Sousa et al 2008, Villac et al 2008, Villac & Tenenbaum 2010, Islabão & Odebrecht 2011, Proença et al 2011, Tiburcio et al 2011, Garcia & Odebrecht 2012, Jardim & Cardoso 2013, Menezes et al 2015. All species synonyms were checked through AlgaeBase, in order to confirm the records in the publications consulted.…”

New distribution records of Dinophyta in Brazilian waters

“…Floristic studies of dinoflagellates in Brazil are relatively few, but among the several important contributions are those of Passavante (1979) for the state of Pernambuco; Passavante et al (1982) for Ceará, Kremer and Rosa (1983) for the region of Tramandaí-Imbé in Rio Grande do Sul, Cardoso (1995Cardoso ( , 1997Cardoso ( , 1998 for northern Santa Catarina Island and Arvoredo Island in Santa Catarina, Koening and Lira (2005) with species of the genus Neoceratium in Pernambuco, Haraguchi and Odebrecht (2010) and Islabão and Odebrecht (2011) for the area between Albardão-Chuí, Rio Grande do Sul, and the Cabo da Santa Marta in Santa Catarina. The small number of studies of Dinophyta in Brazilian waters increases the chances of finding new occurrences for both states and the country, especially because the world biodiversity is estimated at 1555 species (Gómez 2005) in the marine environment.…”
