  journal={Investigaciones Marinas},
The seasonal distribution and vertical migration of gelatinous zooplankton collected in Mejillones Bay was analyzed. The 39 species identified included 14 hydromedusae, 20 siphonophores, and 5 chaetognates. The dominant species were Obelia spp., Liriope tetraphylla, Solmundella bitentaculata, Rophalonema velatum, Muggiaea atlantica, Sphaeronectes gracilis, Sagitta enflata, and S. bierii. Their vertical distribution and nictimeral migration ranges were narrow due to the influence of the Oxygen… Expand

Seasonal and vertical distribution of medusae in Aysén region, southern Chile
Results from the area were compared with previous results, proving that most species identified are common in southern Chilean fjords and channels, thus proving that the jellyfish abundance was higher in spring than in winter. Expand
Seasonal and vertical distributional patterns of siphonophores and medusae in the Chiloé Interior Sea, Chile
Abstract The horizontal and vertical distribution of jellyfish was assessed in the Chiloe Inland sea, in the northern area of the Chilean Patagonia. A total of 41 species of cnidarians (8Expand
Biodiversity and spatial distribution of medusae in the Magellan Region (Southern Patagonian Zone)
Analysis ofipelagic medusae collected in the Magellan Region during spring 2009 confirmed the success of several species in the colonization of the inland waters of the Southern Patagonian Zone. Expand
Horizontal and vertical distributions of siphonophores in relation to oceanographic conditions in Chilean Patagonian fjords
Siphonophores collected in Chilean Patagonian fjords, between the Gulf of Penas and the Trinidad Channel in 2008 were analysed. A total of 12 species were recorded, of which Muggiaea bargmannae,Expand
The ecology and developmental changes of meristic characters of the medusa Malagazzia carolinae (Hydrozoa: Leptothecata) from subtropical Southwestern Atlantic estuaries
It is shown that the meristic marginal characters of the hydromedusa Malagazzia carolinae changes through its ontogeny, suggesting it is well adapted to thrive in estuarine subtropical and tropical systems. Expand

Reproductive patterns in demersal crustaceans from the upper boundary of the OMZ off north-central Chile
It is proposed that for OMZ resident species, brood carrying during warmer and more oxygenated conditions in the adult benthic environment, might favor embryonic development, so OMZ seasonal variability could be acting as a selective pressure to synchronize reproductive periods. Expand
Siphonophores from surface waters of the Colombian Pacific Ocean
Siphonophores abundance was positively related to the abundance of copepods and fish eggs, with the top 13 most abundant species all having positive correlations, suggesting siphonophore abundances are tightly controlled by their food. Expand

Distribution of Euphausia mucronata at the upwelling area of Peninsula Mejillones, northern Chile: The influence of the oxygen minimum layer
Analysis of zooplankton samples from 53 stations obtained around Peninsula Mejillones (Northern Chile), from two strata: 0-50 m and 150-200 m, during active upwelling in December 1996, allowed theExpand
Vertical distribution of epipelagic siphonophores at the confluence between Benguela waters and the Angola Current over 48 hours
The differences in the depth distributions of the various species were related to 3 distinct phenomena: the existence of 2 separate siphonophore populations associated with each of the 2 water masses; vertical migration by the most abundant species, which were able to cross the thermocline; and differences in patch size for the most epipelagic species.

Gelatinous zooplankton assemblages associated with water masses in the Humboldt Current System, and potential predatory impact by Bassia bassensis (Siphonophora: Calycophorae)
The results indicate that B. bassensis was the most important secondary predator in the top 50 m of the water column, and could have had a significant trophic impact on the population of small copepods off the Mejillones Peninsula during the sampling period, where smallCopepods constituted 80.6% of the total mesozooplankton community.

Distributional patterns of the ctenophores Pleurobrachia pileus and Beroe cucumis in the Bay of Fundy region, Canada
The distribution and relative abundance of Pleurobrachia pileus and Beroe cucumis within the Bay of Fundy and adjacent waters were examined over an 8-year period, and the larger numbers of smaller ctenophores within the upper bay and Grand Manan–Maine regions may reflect shrinkage of larger animals because of lack of food.
