High spatial heterogeneity of two planktonic cnidarian species related to the variability of a shelf-slope front at short time scales

Scientia Marina, 2016
We investigated the variability in the mesoscale distribution of the siphonophore Muggiaea atlantica and the hydromedusa Aglaura hemistoma in relation to the rapid spatial oscillations of the shelf-slope front off the Catalan coast (NW Mediterranean ...

Environmental patterns and biomass distribution of gelatinous macrozooplankton. Three study cases in the South-western Atlantic Ocean

Scientia Marina, 2000
Periodic swarms or blooms of gelatinous macrozooplankton have a negative effect on many human activities such as tourism, fisheries, and industry, but for several reasons (sampling procedures, underestimation of their real abundance, etc.), they have ...

Ocean Acidification Alters the Predator – Prey Relationship Between Hydrozoa and Fish Larvae

Frontiers in Marine Science, 2022
Anthropogenic CO2 emissions cause a drop in seawater pH and shift the inorganic carbon speciation. Collectively, the term ocean acidification (OA) summarizes these changes. Few studies have examined OA effects on predatory plankton, e.g.

The distribution of estuarine fish larvae: nutritional condition and co-occurrence with predators and prey [PDF]

, 2000
Fish larvae were collected monthly between March and September 1997 in the Mira and Guadiana estuaries (southern Portugal). Hydrological parameters were registered and zooplankton samples were obtained simultaneously. Densities of fish larvae (ind.100 m(-

Deep-water Hydromedusae from the Lacaze-Duthiers submarine canyon (Banyuls, northwestern Mediterranean) and description of two new genera, Guillea and Parateclaia

Scientia Marina, 2000
Several species of hydromedusae are reported from material collected by sediment traps placed in the Lacaze-Duthiers submarine canyon, off Banyuls (north-western Mediterranean). Two new taxa Guillea canyonincolae gen. nov. et sp. nov.

Medusae and ctenophores from the Bahia Blanca Estuary and neighboring inner shelf (Southwest Atlantic Ocean, Argentina) [PDF]

, 2017
An updated checklist of medusae and ctenophores is presented for the first time for the area comprised by the Bahía Blanca Estuary, the adjacent shelf El Rincón and Monte Hermoso beach, on the southwest coast of Buenos Aires province (Argentina).

Cnidarian Parasites on Solmissus incisa, a Narcomedusa

Scientia Marina, 2000
A narcomedusa, Solmissus incisa, was collected off central California in the Monterey Submarine Canyon at 230 m in October 1996. The medusa was viewed and collected from the RV Point Lobos using the remotely operated vehicle (ROV) Ventana.

The Hunger Games: Stable Isotopes Indicate Winter Inter-Guild Competition for Resources by Marine Meso-Predators in the Sub-Arctic North Pacific. [PDF]

Ecol Evol
There is high niche overlap and potential for competition between Pacific salmon and non‐salmonid meso‐predators in the open ocean during winter. Food web structure and the level of niche overlap varied spatially and depending on the species. The biomass of the competitor species may exceed that of Pacific salmon, with potential implications for ...

Medusan Morphospace: Phylogenetic Constraints, Biomechanical Solutions, and Ecological Consequences [PDF]

, 2008
Medusae were the earliest animals to evolve muscle-powered swimming in the seas. Although medusae have achieved diverse and prominent ecological roles throughout the world\u27s oceans, we argue that the primitive organization of cnidarian muscle tissue ...

Passive Energy Recapture in Jellyfish Contributes to Propulsive Advantage over other Metazoans [PDF]

, 2013
Gelatinous zooplankton populations are well known for their ability to take over perturbed ecosystems. The ability of these animals to outcompete and functionally replace fish that exhibit an effective visual predatory mode is counterintuitive because ...
