New user-friendly identification keys for 117 species of Pectinariidae, Ampharetidae, and Terebellidae from the eastern Atlantic and the North Polar Basin are presented. A new species Auchenoplax worsfoldi sp.n. is described. Three names Amphitrite affinis, Pista malmgreni, and Terebellides irinae are proposed as junior synonyms to other species.

“…The nitrogen to carbon ratio is an index of the nutritional value of the organic matter: food with high carbon and little nitrogen content (e.g., cellulose) is poorly nutritious compared with food that is proportionally richer in nitrogen (e.g., proteins). Inside caves, the ratio can get lower than 6%, a threshold value for animal consumption [89,90].…”

Distribution and Ecology of Decapod Crustaceans in Mediterranean Marine Caves: A Review

et al. 2022

Decapod crustaceans are important components of the fauna of marine caves worldwide, yet information on their ecology is still scarce. Mediterranean marine caves are perhaps the best known of the world and may offer paradigms to the students of marine cave decapods from other geographic regions. This review summarizes and updates the existing knowledge about the decapod fauna of Mediterranean marine caves on the basis of a dataset of 76 species from 133 caves in 13 Mediterranean countries. Most species were found occasionally, while 15 species were comparatively frequent (found in at least seven caves). They comprise cryptobiotic and bathyphilic species that only secondarily colonize caves (secondary stygobiosis). Little is known about the population biology of cave decapods, and quantitative data are virtually lacking. The knowledge on Mediterranean marine cave decapods is far from being complete. Future research should focus on filling regional gaps and on the decapod ecological role: getting out at night to feed and resting in caves during daytime, decapods may import organic matter to the cave ecosystem. Some decapod species occurring in caves are protected by law. Ecological interest and the need for conservation initiatives combine to claim for intensifying research on the decapod fauna of the Mediterranean Sea caves.

“…The composition of sublittoral benthic macrofauna depends on interaction between biotic (food availability, colonizer larvae, predation and competition) and abiotic factors, such as salinity, temperature, depth, oxygen concentration, current speed, stochastic events or sediment grain size (Sanders, 1968; Cocito et al , 1990). Another important factor is the marine bottom relief, which affects deposition and suspension of particles, which in turn affect the trophic structure of the communities (Pearson, 2001).…”

Trophic structure of soft-bottom macrobenthos in an inlet in north-western Spain

2009

View full text Add to dashboard Cite

The trophic composition of macrobenthic communities in intertidal and subtidal soft-bottoms of the Ensenada de San Simón (north-western Spain) was found to be related to a number of environmental variables. Distribution and abundance of trophic groups have been studied, to provide essential baseline information for monitoring the area, after its designation as a Natura 2000 Special Conservation Zone. Analyses of trophic data showed a numerical predominance of the herbivores in the inner part of the inlet, while sites at the oceanic-influenced area were numerically dominated by surface-deposit feeders. These dominances were mainly due to Hydrobia ulvae in the intertidal area and to polychaetes at the subtidal one. Both univariate and multivariate statistical analyses showed that the sediment composition (organic matter and silt–clay contents) and temperature of the bottom water influenced the benthic macrofauna and were correlated with their trophic composition, abundance and distribution.
