Paramuricea clavata Risso, 1826 (Cnidaria: Octocorallia) is a characteristic species of Mediterranean benthic fauna. The natural diet and prey capture rate of the species were studied in the field at the Medes islands (NW Mediterranean Sea) using continuous flow incubation chambers. In situ grazing rates on DOC, detrital POC, and pico-, nano- and microplankton were examined over 1 annual cycle. P. clavata capture nanoeukaryotes, phytoplankton and ciliates as well as detrital POC. Colonies… 

Natural feeding of the temperate asymbiotic octocoral-gorgonian Leptogorgia sarmentosa (Cnidaria: Octocorallia)

TLDR
Natural feeding and respiration of the ubiquitous temperate species Leptogorgia sarmentosa in the NW Mediterranean suggests that there may be important seasonal variations in energy intake, which may affect the seasonal dynamics of temperate octocorals due to the marked seasonal variation in the availability of this particulate carbon source in temperate ecosystems like the Mediterranean.

Natural heterotrophic feeding by a temperate octocoral with symbiotic zooxanthellae: a contribution to understanding the mechanisms of die-off events

TLDR
Heterotrophic nutrition in the natural environment seems unable to meet basal metabolic requirements, especially in summer and fall, which indicates the occurrence of a resource acquisition limitation that may play a role in the repeated summer die-off events of E. singularis.

Diet and seasonal prey capture rates in the Mediterranean red coral (Corallium rubrum L.)

TLDR
A high variability in the annual cycle of prey capture rate, prey size and ingested biomass is found compared to other Mediterranean gorgonians, suggesting that unexploited red coral populations may have a high impact compared with other passive suspension feeders.

Temporal changes in the trophic ecology of the asymbiotic gorgonian Leptogorgia virgulata

TLDR
Results support a distinct temporal shift in the diet of L. virgulata, and suggest that this dominant species in the western Atlantic Ocean may be an opportunistic feeder, and seasonal shifts in food availability in the water column affect its diet.

Role of small-plankton communities in the diet of two Antarctic octocorals (Primnoisis antarctica and Primnoella sp.)

TLDR
Feeding experiments showed that components of the seston, including the finer fraction of suspended organic matter (ciliates, dinoflagellates and phytoplankton), are also an impor- tant part of the octocoral diet.

Temporal variability in zooplankton prey capture rate of the passive suspension feeder Leptogorgia sarmentosa (Cnidaria: Octocorallia), a case study

TLDR
The temporal variability in zooplankton prey capture of the ubiquitous Mediterranean gorgonian Leptogorgia sarmentosa indicates that predation by macroinvertebrates on seston should be considered in energy transfer processes in littoral areas, since even species with a low abundance may have a detectable impact.

Role of benthic cnidarians in energy transfer processes in the Southern Ocean marine ecosystem (Antarctica) = Rolle der bodenlebenden Nesseltiere im Stofffluß des marinen Ökosystems des Südpolarmeeres (Antarktis)

TLDR
Data related with low CIN ratio in the sediment and high NO2 concentrations in areas with dense communities of benthic suspension feeders, along with data on capture rates, lead it to hypothesize that these organisms play an important role in the recycling processes of organic matter in Antarctic benthics ecosystems.

Feeding ecology and trophic impact of the hydroid Obelia dichotoma in the Kongsfjorden (Spitsbergen, Arctic)

TLDR
To study qualitatively and quantitatively the diet of these organisms in an Arctic environment and to determine their trophic significance, the density of the hydroid population was documented, and simultaneously, zooplankton was sampled in two different years.

Diets and Seasonal Ingestion Rates of Aurelia coerulea (Cnidaria: Scyphozoa) Polyps by in situ Feeding Experiments in Jiaozhou Bay, China

The benthic scyphopolyp population is an important stage in the scyphozoan lifecycle. Nevertheless, few studies have detailed the natural feeding and quantified the energy flux of polyps based on

Trophic ecology of Caribbean octocorals: autotrophic and heterotrophic seasonal trends

TLDR
It is demonstrated that there are species-specific and seasonal differences in the contributions of these two nutrition modes, though there is no indication of shifts in the predominant mode during the year in either species.

Seasonal variation of in situ feeding rates by the temperate ascidian Halocynthia papillosa

TLDR
The natural diet and prey capture rate of the temperate ascidian Halocynthia papillosa were studied in the field in a Western Mediterranean population and suggest that factors other than food availability determine the seasonal dynamics of the species.

TLDR
It is conservatively estimated that through active suspension feeding, sponges are a sink for 1.97 g C d -1 m -2 , mostly from procaryotic cell types.

Flow-dependent herbivory and growth in zooxanthellae-free soft corals

TLDR
A carbon budget for Dendronephthya hemprichi is presented, synthesizing field data on somatic growth, food intake, and respiration, and the ability of octocorals to feed on phytoplankton is probably related to the narrowly spaced pinnules on their tentacles as well as morphological and behavioral adaptations to living in strong flow.

Heterotrophic feeding by gorgonian corals with symbiotic zooxanthella

TLDR
In this study, in situ rates of grazing on pico-, nano-, and microplankton, zooxanthellae release, and respiration for the ubiquitous symbiotic gorgonian coral Plexaura flexuosa were measured.

Feeding and prey capture cycles in the aposymbiontic gorgonian Paramuhcea clavata

TLDR
The prey capture rates recorded during a die1 cycle, when extrapolated to an annual cycle, suggest that gorgonians play an important role in littoral food webs and particularly in the flow of energy from the plankton to the benthos.

Ingestion Rates and Absorption Efficiencies ofAbra ovata(Mollusca: Bivalvia) Fed on Macrophytobenthic Detritus

TLDR
Anegative effect of both protein and phenolic contents on ingestion rates, and a negative effect of phenolic Contents on absorption efficiencies are shown, in good agreement with the existing literature.

Structure of cnidarian populations in mediterranean sublittoral benthic communities as a result of adaptation to different environmental con ditions

TLDR
It is suggested that the difference of water flow conditions in these three cornmunities leads to the development of different spatial pattems of individuals and colonies, and the most structured community had the largest organisms with the longest life spans.

Reproduction and cycle of gonadal development in the Mediterranean gorgonian Paramuricea clavata

TLDR
The reproductive biology of this species was studied from 1990 to 1992 off the Medes Islands and spawned eggs adhered, through the action of a mucous coating, to the outer surfaces of the female colonies.

Phytoplankton depletion in the benthic boundary layer caused by suspension-feeding Nereis diversicolor (Polychaeta): grazing impact and effect of temperature

TLDR
It was demonstrated that the ab~h ty of the worms to deplete the bottom water of phytoplankton was highly correlated with temperature dependent f~ltration and water pumplng capac~ty and algal depletion above dense populations of suspens~on-feeding N d~verslcolor may occur frequently.

TLDR
Reduction in phytoplankton concentrations in the near-bottom water layer, 5 to 10 cm in thickness on calm days, may play a significant role for the filter-feeding polychaete Nereis diversicolorin realizing its grazing capacity.
