Dissolved organic matter fluxes and fatty acid composition from shallow-water and deep-water demo- and hexactinellid sponges from New Zealand

This study examines dissolved organic matter (DOM) fluxes and fatty acid composition in New Zealand sponges, finding that some species release TDN and alter FDOM fluorophores, suggesting bacterial involvement in DOM transformation.

Nutrient fluxes, oxygen consumption and fatty acid composition from deep-water demo- and hexactinellid sponges from New Zealand

This study examines nutrient fluxes, oxygen consumption, and fatty acid composition in deep-water sponges from New Zealand, identifying differences in nitrogen cycling and microbial communities among sponge clusters.

Role of Astrophorina sponges (Demospongiae) in food-web interactions at the Flemish Cap (NW Atlantic)

The paper assesses the ecological role of Astrophorina sponges in deep-sea food webs at the Flemish Cap by analyzing trophic and non-trophic interactions across four assemblages.

Deconvolving feeding niches and strategies of abyssal holothurians from their stable isotope, amino acid, and fatty acid composition

This study uses stable isotopes, amino acids, and fatty acids to determine the trophic niches and feeding strategies of abyssal holothurians in the Peru Basin.

Habitat types and megabenthos composition from three sponge-dominated high-Arctic seamounts

The paper assesses habitat types and megabenthos composition on three Arctic seamounts, finding demosponges dominate megabenthos across all sites.

Role of polymetallic-nodule dependent fauna on carbon cycling in the eastern Clarion-Clipperton Fracture Zone (Pacific)

This paper assesses the impact of removing nodule-dependent fauna on carbon cycling in the eastern CCZ using food web models, finding that nodule-dependent fauna contribute minimally to total carbon cycling but significantly affect the scavenger loop.

Polymetallic nodules are essential for food-web integrity of a prospective deep-seabed mining area in Pacific abyssal plains

This study assesses the impact of polymetallic nodule removal on food-web integrity in two abyssal seafloor regions using trophic and non-trophic interaction webs.
