It is particularly interesting that despite its introduction into the Atlantic basin over 45 yr ago (Moreira 1961, Graham et al 2003a) and the amount of ship traffic between the Caribbean and GOM, Phyllorhiza punctata has only recently emerged in the Mississippi Bight.…”

In the spring of 2000, millions of the non-endemic jellyfish Phyllorhiza punctata were found in coastal regions of the Mississippi Bight in the northern Gulf of Mexico. The aggregations were large enough to seriously impact local fisheries by clogging shrimp nets and damaging gear. More importantly perhaps, the impact on plankton biomass and hence on fishery resources were potentially large, since P. punctata is a voracious filter feeder. In this study, we examine a hypothesis for their sudden appearance which involves advection from the Caribbean in an intruding Loop Current and subsequent flux onto the Mississippi Shelf through eddy-shedding processes which interact with the continental shelf/slope. Surface current data were obtained from an archived finite difference model of the Gulf of Mexico which used altimeter data assimilation and real wind forcing covering the time of the invasion. Model and satellite data showed that an exchange event occurred in late April at a time appropriate for the invasion. The results from tracing transport pathways suggest that mass redistribution of Caribbean populations into the northern Gulf of Mexico can be accomplished via Loop Current intrusion and flux of deep basin water onto the shelf. As such, the occurrence of the invasive species P. punctata in the northern Gulf in 2000 can be explained by a natural, but not necessarily common, sequence of events. This hypothesis is discussed as a means of redistribution of a species by invasion as opposed to redistribution by diffusive spreading.

(2003a) provided the first published report of the invasion of Phyllorhiza punctata in the Mississippi Bight, there are a number of credible anecdotal reports that smaller aggregations of these medusae had been occurring for several years prior to 2000 along southern Louisiana west of the mouth of the Mississippi River, specifically in Terrebone Bay. While the potential for spreading from this source exists, we must still consider the possibility of periodic introductions of expatriate medusae from a Caribbean source with or without establishment of a population of scyphistomae in the northern GOM. The suddenness and magnitude of the 2000 event suggests that more than local spreading is involved. The purpose of this study was to investigate the possibility that the summer 2000 population of P. punctata medusae could have been transported from the Caribbean into the northern GOM over a relatively short period of time consistent with the biological constraints of these jellyfish (i.e. life-history and survival). This was accomplished by employing a re...

Most of the scyphozoans and cubozoans recorded for the Brazilian coast are presumed to be distributed over the entire coastline, but little information on precise records is available. This paper presents the first published records for the Ceará state (northeastern region) of the cubozoan Chiropsalmus quadrumanus, and the scyphozoans Chrysaora lactea, Linuche unguiculata (polyp), Lychnorhiza lucerna, Nausithoe sp. (polyp), Phyllorhiza punctata, and Stomolophus meleagris. The medusoid species have been known by local fishermen and non-specialists for a long time in the area. A maioria das cifomedusas e cubomedusas registradas para o litoral brasileiro é presumivelmente distribuída por toda a costa; porém poucos registros precisos estão disponíveis. Este estudo apresenta os primeiros registros publicados para o estado do Ceará (região Nordeste) da cubomedusa Chiropsalmus quadrumanus, e dos cifozoários: Chrysaora lactea, Linuche unguiculata (pólipo), Lychnorhiza lucerna, Nausithoe sp. (pólipo), Phyllorhiza punctata and Stomolophus meleagris. As espécies de medusas são conhecidas de longa data por pescadores locais e não-especialistas no grupo.

ABSTRACT.We report the association between the jellyfish Lychnorhiza lucerna and the crab Cyrtograpsus affinis. Numerous examples of associations between medusae and brachyurans have been observed in the field and noted in the literature. All of these cases involve medusae of the Class Scyphozoa and crabs belonging to the families Majidae and Portunidae. The presence of three individuals of C. affinis within the subgenital space of L. lucerna constitutes a striking finding since none species of this brachyuran family (Varunidae) has been previously reported associated to scyphomedusae. Keywords: symbiosis, jellyfish, brachyurans, Río de la Plata, southwestern Atlantic, Argentina.Primer registro de la asociación entre Lychnorhiza lucerna (Scyphozoa, Rhizostomeae) y Cyrtograpsus affinis (Decapoda, Varunidae) RESUMEN. Se reporta la asociación entre la medusa Lychnorhiza lucerna y el cangrejo Cyrtograpsus affinis. Existen numerosos ejemplos de asociaciones entre medusas y brachiuros mencionados en la literatura. Todos ellos involucran a las medusas de la Clase Scyphozoa y a cangrejos pertenecientes a las familias Majidae y Portunidae. La presencia de tres individuos de C. affinis dentro de la cavidad subgenital de L. lucerna es un hecho llamativo dado que, hasta el momento, no se había reportado a ninguna especie de esta familia de brachiuros (Varunidae) asociada con medusas de la Clase Scyphozoa.
