Trophic plasticity of Antarctic echinoids under contrasted environmental conditions

Echinoids are common members of Antarctic zoobenthos, and different groups can show important trophic diversity. As part of the ANT-XXIX/3 cruise of RV Polarstern, trophic plasticity of sea urchins was studied in three neighbouring regions (Drake …

Sediment carbon sink in low-density temperate eelgrass meadows (Baltic Sea)

Seagrass meadows are highly productive habitats that can act as “blue carbon sinks” in coastal ecosystems by facilitating sedimentation and trapping particles. However, the magnitude and occurrence of these effects may be species and density …

Passive acoustic recording of *Ophidion rochei* calling activity in Calvi Bay (France)

Passive acoustic recording (PAR) systems are non-invasive and allow researchers to collect data on large spatial and temporal scales. Since fish sounds are species-specific and repetitive, PAR can provide a large amount of data about spatio-temporal …

AxIOM: Amphipod crustaceans from insular *Posidonia oceanica* seagrass meadows

Background: The Neptune grass, *Posidonia oceanica* (L.) Delile, 1813, is the most widespread seagrass of the Mediterranean Sea. This foundation species forms large meadows that, through habitat and trophic services, act as biodiversity hotspots. In …

Epiphytic bryozoans on Neptune grass – a sample-based data set

Background: The seagrass *Posidonia oceanica* L. Delile, commonly known as Neptune grass, is an endemic species of the Mediterranean Sea. It hosts a distinctive and diverse epiphytic community, dominated by various macroalgal and animal organisms. …

Trophic interactions between two neustonic organisms: insights from Bayesian stable isotope data analysis tools

The by-the-wind sailor *Velella velella* (Linnaeus, 1758) and its predator, the violet snail *Janthina globosa* (Swainson, 1822) are both floating neustonic organisms. Despite their global oceanic distribution and widespread blooms of *V. velella* in …

Trophic ecology of the seagrass-inhabiting footballer demoiselle *Chrysiptera annulata* (Peters, 1855); comparison with three other reef-associated damselfishes

Many damselfishes (Pomacentridae) are herbivorous or omnivorous with an important contribution from different kinds of algae in their diet. they display different levels of territoriality and farming behavior, from almost non territorial to …
