Seasonal variation of large medusae abundance and biomass was studied in the North Bay, Santa Catarina, southern Brazil (27°30'S, 48° 32'W), from February to December 2005. Collecting was conducted seasonally with the help of fishing bottom trawl in 30-minute sections (12 in summer, 18 in each of the remaining seasons) in six stations, totaling 66 samples. Eight species were found: the hydrozoans Aequorea sp., Olindias sambaquiensis Müller, 1861, and Rhacostoma atlantica L. Agassiz, 1850; the cubozoans Chiropsalmus quadrumanus (Müller, 1859) and Tamoya haplonema Müller, 1859, and the scyphozoans Aurelia sp., Chrysaora lactea Eschscholtz, 1829 and Lychnorhiza lucerna Haeckel, 1880. Capture rates were low, up to 38 indiv. ha-1, and only ~47% of the samples were positive for jellyfish, comprising 206 individuals. Medusae abundance and species richness clearly changed from one season to another, but did not vary between the sites. Higher species richness (7 out of 8) and greater abundances were recorded during the fall (~60% and 72% of all medusae individuals and biomass respectively). Specific frequency of capture varied from 1.5 to 29% and C. lactea was the only species found in more than 25% of the samples. The three most common species dominated in different periods of the year: C. lactea during fall (78% of individuals and 60% of biomass), R. atlantica during winter (90% of individuals and 17% of biomass), and O. sambaquiensis in spring (78% of individuals and 40% of biomass). Only two individuals were caught during summer, one C. lactea and one R. atlantica. The results offer a general picture of the distribution of the macromedusae in the North Bay, but a continuous monitoring is desirable for a more detailed knowledge on the jellyfish dynamics in the Brazilian coastal waters

“…This commenced in the late 1940s (one new record each of Anthoathecata and Limnomedusae; 27 of Leptothecata); reached an apogee during the 1950s (17 new records of Anthoathecata; 15 of Leptothecata; eight of Narcomedusae; and six of Trachymedusae), declined again during the 1960s (seven new records of Anthoathecata; five of Leptothecata; and one of Trachymedusae). This burst of knowledge of hydrozoan systematics was due to the studies of Dr. Marta Vannucci (Vannucci Mendes, 1946, 1948Vannucci, 1949;1950, 1951a, 1951b1954;1956;1957a;1957b;1960;1963;Vannucci & Ribeiro, 1955;Vannucci & Rees, 1961;Vannucci & Moreira, 1966).

Synopsis of knowledge on Cnidaria Medusozoa from Brazil

Synopsis of knowledge on Cnidaria Medusozoa from Brazil A synopsis of knowledge concerning Medusozoa (Cnidaria) along the Brazilian coast is presented. We generated a data list with all records of medusozoans from Brazil, including information on the distribution of the species and the phase (polyp or medusa) recorded. Currently the number of species of Medusozoa recorded from Brazil is 377 (205 genera and 82 families), with 348 species of hydrozoans, 22 scyphozoans, 3 cubozoans and 1 staurozoan. Geographical and historical analyses were carried out based on the data list. The geographical analysis reveals that knowledge on biodiversity of the group is most inadequate for the North and part of the Northeastern coast. Although the Southeastern coast is the best known region in number of species and representative suprageneric taxa recorded, in general there is a lack of knowledge of the fauna in other than shallow waters, a pattern also observed for all other regions. Historically, the rapid increase of records on hydrozoans began in the 1940s and accelerated during the last decade. Investigations on coronates are all concentrated in the last decade but, in general, other groups show slow and gradual accumulation of species records. Guidelines and policies for the study of medusozoan biodiversity are suggested.

Este estudo é baseado em uma lista com todos os registros de Medusozoa para o Brasil, incluindo informações sobre a distribuição das espécies e suas fases (pólipo ou medusa). O número de espécies de Medusozoa registradas para o Brasil até o momento é 377 (205 gêneros e 82 famílias), com 348 espécies de hidrozoários, 22 de cifozoários, 3 de cubozoários e 1 de estaurozoário. Análises geográfica e histórica também foram conduzidas. A análise geográfica mostra claramente a ausência de conhecimento sobre a biodiversidade da costa norte bem como de parte da costa nordeste do país. Embora a costa sudeste seja a melhor conhecida em termos de números de espécies e representantes de táxons supragenéricos registrados, há em geral ausência de conhecimento sobre ambientes diferentes das águas rasas, um padrão também observado para as outras regiões. Historicamente, o crescimento dos registros de hidrozoários iniciou-se após a década de 1940, com um aumento na última década; os estudos com coronados estão todos concentrados na última década mas, em geral, outros grupos mostram um acúmulo lento e gradual nos registros de espécies. Linhas gerais e políticas para o estudo da biodiversidade dos Medusozoa são sugeridas. cifozoários, cubozoários, estaurozoários, Fauna, Atlântico Sul, Pólipo, Medusa, Brasil Biota Neotropica v3 (n2) -http://www.biotaneotropica.org.br/v3n2/pt/abstract?inventory+BN01203022003 Palavras-chave:hidrozoários,
