Ecological and acoustic investigations of jellyfish (Scyphozoa and Hydrozoa)

The abundance of medusae in regions of the North Sea to climatic fluctuations, as quantified by the North Atlantic Oscillation Index, is linked and shown to be important indicators of regional ecosystem change.

Interactions of pelagic cnidarians and ctenophores with fish: a review

Medusae, siphonophores and ctenophores (here grouped as `pelagic coelenterates') interact with fish in several ways. Some interactions are detrimental to fish populations, such as predation by

An Overview of the Medusozoa from the Southwestern Atlantic

Medusozoans are critical components of coastal and marine ecosystems. They are ubiquitous, living from the surface to the bottom layers of the world’s oceans and tolerating a wide range of

Feeding and asexual reproduction of the jellyfish Sarsia gemmifera in response to resource enrichment

The food concentrations which S. gemmifera normally experiences in the field are much lower than the food levels at which this species had its maximum asexual reproductive output in the laboratory, so this species may potentially benefit from food web perturbations which increase crustacean zooplankton densities.

Jellyfish blooms: Crambionella orsini (Scyphozoa: Rhizostomeae) in the Gulf of Oman, Iran, 2002–2003

In 2002, a jellyfish bloom occurred throughout the Gulf of Oman and the Persian Gulf causing decreased catch in artisanal and industrial fisheries, damage to fishing gear, interrupted operation of

Diversity and occurrence of siphonophores in Irish coastal waters

Comparing siphonophores in Bantry Bay and the Western English Channel (Plymouth Marine Laboratory's L4 station) indicates both regions share a similar pattern of inter-annual occurrence and provides novel information on the seasonality and occurrence of siphons in Irish coastal waters.

Degradation of the Adriatic medusa Aurelia sp. by ambient bacteria

Despite divergence in the bacterial community responses to jellyfish homogenate, increased bacterial biomass and growth rates in both distinctive marine systems indicate potentially significant effects of decaying jellyfish blooms on microbial plankton.

Feeding Ecology and Metabolism of the Antarctic Cydippid Ctenophore Callianira Antarctica

Investigation of the chemical composition, metabolism, and feeding ecology of the cydippid ctenophore Callianira antarctica suggest that this species is an opportunistic predator that feeds both during the day and night, and appears to be well adapted to the prey patchiness found in Antarctic waters.

Feeding on survival-food: gelatinous plankton as a source of food for anchovies

The environmental and biological conditions that led a normally planktivorous filter feeder E. anchoita to prey on gelatinous plankton are described.

Increases in jellyfish biomass in the Bering Sea: implications for the ecosystem

The hypothesis that the presence of these large carnivores has affected fisheries resources, either through direct predation on larval stages, or through compe- tition for zooplankton prey is examined.

Selective predation and caloric consumption by the siphonophore Rosacea cymbiformis in nature

Individuals of the siphonophore Rosacea cymbiformis (Chiaje, 1822) were collected in surface waters of the Gulf of California during July/August 1978, off Southern California during May 1980, and in

Feeding ecology of Rhizophysa eysenhardti, a siphonophore predator of fish larvae1

The heavy predation on fish larvae by R. eysenhardti suggests that both fish mortality and siphonophore population growth may be strongly affected.

Dietary composition and diel feeding patterns of epipelagic siphonophores

For a given siphonophore species, the number of ingested prey was greatest at localities where prey organisms were most abundant in the surrounding seawater, and there was a tendency for more prey to be consumed at night.

THE FUNCTIONS OF NEMATOCYSTS IN PREY CAPTURE BY EPIPELAGIC SIPHONOPHORES (COELENTERATA, HYDROZOA)

Examination by SEM of captured, but uningested prey showed that the heavily-spined threads of these nematocysts adhered to the prey surface, and primarily entangled the prey.

QUANTITATIVE NATURAL HISTORY OF PLEUROBRACHIABACHEI IN LA JOLLA BIGHT

An assessment of the quantitative natural history of Pleurobrachia bachei was made by estimating growth rates, metabolic rates, distribution, abundance, occurrence of prey, predators and parasites, population parameters, and net production, which suggested the ecological significance and functional role of this animal in the plankton.

Effects of predation by the scyphomedusan Chrysaora quinquecirrha on zooplankton populations in Ches

The diet, digestion times, and d e n s ~ t ~ e s of Chrysaora quinquecirrha medusae, and densities of their prey were quantified in order to evaluate the importance of this conspicuous scyphomedusan

Mass occurrence of Periphylla periphylla (Scyphozoa, Coronatae) in a Norwegian fjord

High densities of this species have persisted for about 20 years and impeded fishing in Lure~orden, western Norway, and it is probably the major pelagic predator in the fjord.
