We have compiled available records in the literature for medusozoan cnidarians and ctenophores of South America. New species are also included. Each entry (i.e., identified or still as yet not determined referred to "sp." literature) includes a synonymy list America, taxonomical remarks, notes on habit, information geographical occurrence. listed 800 unique species, 958 morphotype entries: 5 cubozoans, 905 hydrozoans, 25 scyphozoans, 3 staurozoans, 20 ctenophores. Concerning nomenclatural...
Early naturalists suggested that predation intensity increases toward the tropics, affecting fundamental ecological and evolutionary processes by latitude, but empirical support is still limited. Several studies have measured consumption rates across latitude at large scales, with variable results. Moreover, how affects prey community composition such geographic scales remains unknown. Using standardized experiments spanned 115° of 36 nearshore sites along both coasts Americas, we found...
The study of biological invasions can be roughly divided into three parts: detection, monitoring, mitigation. Here, our objectives were to describe the marine fauna area port São Sebastião (on northern coast state Paulo, in Channel, SSC) detect introduced species. Descriptions faunal community SSC with respect native and allochthonous (invasive or potentially so) diversity are lacking for all invertebrate groups. Sampling was carried out by specialists within each taxonomic group, December...
Stragulum bicolor n. gen. & sp. (Octocorallia: Clavulariidae) is described from Brazil. It was found in shallow waters of the States Ceará, Rio de Janeiro, São Paulo, Paraná and Santa Catarina, probably invasive. The genus forms encrusting sheets on solid objects, such as seaweed basal stems, barnacle shells artificial substrates. new taxon has spindles, crosses radiates outer layer coenenchyme, fused sclerites interior polyps are unarmed. compared with other taxa that have sclerites.
Different substrates of varying composition, color, texture and orientation may selectively influence recruitment sessile invertebrates thereby the resultant community. Thus act as a barrier to establishment non-indigenous species (NIS). In southern Brazil, granite is main rock forming natural rocky walls that are available for encrusting organisms. this study we tested whether influences impedes colonization by introduced cryptogenic already established on artificial within region. Plates...
The spatial and temporal variations of planktonic cnidarians were studied across the inner continental shelf (≤40 m) off State Paraná in southern Brazil. Monthly zooplankton samples taken between November 1997 March 1999 at five stations. holoplanktonic Liriope tetraphylla Muggiaea kochi dominated during entire period, comprising >80% specimens. coast–ocean gradient became evident due to a near-coastal (≤20 assemblage formed by L. tetraphylla, Solmaris corona meroplanktonic medusae,...
The scyphozoan Phyllorhiza punctata von Lendenfeld, 1884 (Mastigiidae), known only from Indo-Pacific waters prior to the 1950s, is today found far its original distribution, probably due human activities. First seen in 1955 Brazilian waters, medusae were southern and southeastern coasts, disappearing (at least as a medusa) early 1960's. Another population was late 1990's, state of Bahia, again 2001, many sightings reported along coasts Paraná Santa Catarina (25º20'S, 48º12'W 27º26'S,...
The diet of cubomedusae Tamoya haplonema Müller, 1859 (Carybdeidae) and Chiropsalmus quadrumanus (Müller, 1859) (Chirodropidae) was examined in specimens collected on the Southern Brazilian coast (25º20' - 25º55'S; 48º10' 48º35'W), between December 1998 2004. This is first study to analyze this biological aspect from South Atlantic. gastrovascular cavities most (55%; n = 29) T. were empty while remainder had teleosteans parts such as scales, vertebrae otoliths. In C. (n 726), important items...
The present paper reports on 22 species collected by the Brazilian Program of Living Resources in Exclusive Economic Zone (REVIZEE). A new genus and Cribrilinidae, Corbuliporina crepida n. gen. et sp., is described, along with seventeen other species: Chaperia brasiliensis Amastigia aviculifera Isosecuriflustra pinniformis Cellaria subtropicalis Melicerita Arachnopusia haywardi Smittina migottoi Hippomenella amaralae Rogicka joannae Malakosaria atlantica Turbicellepora winstonae Rhynchozoon...
Associations between jellyfish and other organisms are frequently reported. Neverhteless, few of those records include crabs inhabiting medusae. Lychnorhiza lucerna Haeckel, 1888 were sampled (n = 1988) on the coast State Paraná (25º20'-25º55'S, 48º10'-48º35'W), southern Brazil, from December 1997 to 2004. Eight percent (166 individuals) medusae had one spider crab Libinia ferreirae Brito Capello, 1871 living within its subgenital porticus or oral arms. Megalopal stages same also found three...
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 conducted seasonally with help fishing bottom trawl 30-minute sections (12 summer, 18 each remaining seasons) six stations, totaling 66 samples. Eight species were found: hydrozoans Aequorea sp., Olindias sambaquiensis Müller, 1861, Rhacostoma atlantica L. Agassiz, 1850; cubozoans Chiropsalmus quadrumanus...
This study is the first faunistic inventory of hydromedusae from inner continental shelf Paraná State. We describe composition species, collected with bottom-trawl and Hensen nets, in campaigns carried out 1997 to 2006. analyzed 17,797 specimens 578 samples, provide descriptions, photographs, information about biology 22 species found. All had previous records Brazilian coast; however, this record Bougainvillia frondosa, Ectopleura dumortieri, Cirrholovenia tetranema, Eucheilota maculata,...
Podocoryna loyola, a new hydractiniid species, has been found on artificial substrates in Baía de Paranaguá, southern coast of Brazil, since April 2007. Its main morphological characteristics are: (1) polymorphic colonies with reticular stolons or encrusting hydrorhiza not covered by periderm and smooth chitinous spines; (2) newly-released medusae eight tentacles small interradial gonads; (3) mature unbranched oral lips; gastric peduncle absent. Molecular data show that P. loyola is distinct...
Despite the great advances in research on taxonomy and ecology of hydroids Brazilian coast, those studies are concentrated Southeast South regions country, leaving a gap knowledge from North Northeast regions. Aiming to fill part this gap, we studied communities state Sergipe, Brazil, continental shelf three estuarine In shelf, samplings with fishing trawls took place during dry rainy seasons 1999-2003 (8 campaigns), 18 stations distributed at depths 10, 20, 30 m. estuaries rivers...
A fauna de hidroides bentônicos do infralitoral raso, seis locais município Bombinhas (Santa Catarina, Brasil), foi pesquisada e analisada com base na morfologia. O cnidoma examinado quando necessário para a identificação específica. Foram encontradas 25 espécies, das quais cinco (20%) são registradas pela primeira vez o estado Santa Catarina três (12%) região sul Brasil. Houve um acréscimo 12% 5,5% nos registros espécies litoral brasileiro, respectivamente.
Staurozoa is a class of Cnidaria comprising stalked, benthic jellyfishes (Marques & Collins 2004) that encompasses about 51 species (Mills 1999; Zagal et al. 2011). Stauromedusae are distributed worldwide, but more common in temperate and polar waters Hirano 2007). Taxonomic knowledge these cnidarians inadequate, as information on their biology ecology, probably because cryptic habit general inconspicuousness Consequently, scarcity material renders taxonomy even difficult, demanding...
Abstract A new hydromedusa species of the genus Bougainvillia (Anthoathecata; Bougainvillidae) is described. pagesi sp. nov. was collected in shallow coastal waters from southern Brazil (~25–26°S) and northern Argentina (~36–38°S). It differs other mainly by two characters: (i) relatively large size (up to ~20 mm wide high) (ii) voluminous folded hanging gonads at perradial walls manubrium extending proximal region radial canals. Its cnidoma similar genus, with desmonemes (undischarged...
Knowledge about the seasonal patterns of recruitment and growth a non-native species is precondition to forecast its effect on native community. The aim this study was analyse seasonality hydrozoan Podocoryna loyola, possible hydroid in southern Brazilian estuaries, sets polyethylene plates, submerged every three months over four years (April 2009 April 2013), Paranaguá Bay. species’ abundance measured as cover, area number colonies. These measures showed same pattern variation cycles, with...
