Omnivory by the Small Cosmopolitan Hydromedusa Aglaura Hemistoma [PDF]

open access: yes, 2005
We investigated the feeding of the small hydromedusa, Aglaura hemistoma (bell diameter \u3c 4 mm), to determine if it occupies a trophic position similar to that of large medusae.

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

open access: yesScientia 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.

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

open access: yesFrontiers 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.

Morphological diversity of medusan lineages constrained by animal–fluid interactions [PDF]

open access: yes, 2007
Cnidarian medusae, commonly known as jellyfish, represent the earliest known animal taxa to achieve locomotion using muscle power. Propulsion by medusae requires the force of bell contraction to generate forward thrust.

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

open access: yesScientia 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 ...

Population Structure Plays a Key Role in Community Stability. [PDF]

open access: yesEcol Lett
Population structure is a widespread yet underappreciated feature of ecological communities. Here, we develop a general theoretical framework integrating life‐stage structure into community matrix models and show that stage‐specific interactions—especially asymmetric predator‐prey dynamics—can fundamentally alter stability outcomes. Our findings reveal

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

open access: yesScientia 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 ...

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

open access: yes, 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(-

Cnidarian Parasites on Solmissus incisa, a Narcomedusa

open access: yesScientia 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.

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

open access: yes, 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).
