Sponges are one of the major invertebrate groups inhabiting hard-bottom communities worldwide. In this study, we measured in situ rates of grazing on DOC (dissolved organic carbon), POC (particulate organic carbon), and pico-, nanoand microplankton for the common temperate sponge Dysidea avara throughout a yearly cycle. The natural diet of the species was h~ghly heterogeneous and included procaryotes (heterotrophc bacteria, Prochlorococcus sp., Synechococcus sp.) and eucaryotes (protozoa… Expand
Selective uptake of prokaryotic picoplankton by a marine sponge (Callyspongia sp.) within an oligotrophic coastal system
TLDR
These flux estimates quantify the role of a demosponge species in the ultimate fate of prokaryotic picoplankton within the nearshore food webs of southwestern Australia, and support the conclusion that sponges actively select food particles that optimise their nutritional intake. Expand
In situ feeding and metabolism of glass sponges (Hexactinellida, Porifera) studied in a deep temperate fjord with a remotely operated submersible
TLDR
Reported mean sponge abundances indicate that the sponge filtering activity may significantly affect the deep microbial community and benthic–pelagic mass exchange in some north– east Pacific fjords. Expand
Diet Composition of Two Temperate Calcareous Sponges: Leucosolenia echinata and Leucetta sp. from the Wellington South Coast, New Zealand
TLDR
This study is the first to investigate the natural diet of calcareous sponges in temperate rocky subtidal reefs using flow cytometry and it provides evidence for differences in the diets of calCareous spongees and demosponges. Expand
Heterotrophy in the Mediterranean symbiotic coral Cladocora caespitosa: comparison with two other scleractinian species
This experimental study assessed the grazing rates of the Mediterranean symbiotic coral Cladocora caespitosa on the 4 main food sources available in its natural environment: detrital partic- ulateExpand
Ability of mobile cells of the freshwater sponge Ephydatia fluviatilis (Porifera, Demospongiae) to digest diatoms
TLDR
Although sponges are known to host auto‐ and heterotrophic symbionts, this is the first report of their progressive digestion of endocellular diatoms up to the final fragmentation of their frustule. Expand
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. Expand
The natural diet of a hexactinellid sponge: Benthic–pelagic coupling in a deep-sea microbial food web
TLDR
The diet, rates of water processing, and abundance of the deep-sea hexactinellid sponge Sericolophus hawaiicus are quantified, and it is found that, like their demosponge relatives in shallow water, hexACTinellids are a significant sink for ultraplankton. Expand
The role of Mediterranean sponges in benthic–pelagic coupling processes: Aplysina aerophoba and Axinella polypoides case studies
TLDR
The present approach allowed a spatially explicit quantification of benthic–pelagic coupling processes produced by two of the most common sponges in a Mediterranean coastal area and mirrors similar approaches used in terrestrial forestry studies for C flux estimation. Expand
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. Expand
Size independent selective filtration of ultraplankton by hexactinellid glass sponges
TLDR
It is suggested that selective filtration involves individual processing, recognition, sorting, and transport of each particle through the sponges' syncytial tissue in order to shape microbial communities in the detrital food web of North-East Pacific fjords. Expand

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. Expand
Trophic effects of sponge feeding within Lake Baikal's littoral zone. 2. Sponge abundance, diet, feeding efficiency, and carbon flux
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. Expand
Partial Carbon and Energy Budgets of the Bacteriosponge Verohgia fistularis (Porifera: Demospongiae) in Barbados
TLDR
The nutrient resource spectrum of Verongia fistularis and other bacteriosponges appears to be overwhelmingly dominated by dissolved organic matter, and thus contrasts strikingly with the present knowledge of nutrition in the normal non-bacteriosponge sponges. Expand
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. Expand

TLDR
It is suggested that the cycles of toxin production in the encrusting sponge Crambe crambe are driven by internal, physiological factors, although they can be modulated to a considerable extent by local environmental pressures, such as competition with neighbours. Expand
