Sponges as “living hotels” in Mediterranean marine caves

open access: yesScientia Marina, 2016
Although sponges constitute the dominant sessile organisms in marine caves, their functional role as ecosystem engineers has received little attention in this habitat type.

Early animal evolution: a morphologist's view [PDF]

open access: yesRoyal Society Open Science, 2019
Two hypotheses for the early radiation of the metazoans are vividly discussed in recent phylogenomic studies, the ‘Porifera-first’ hypothesis, which places the poriferans as the sister group of all other metazoans, and the ‘Ctenophora-first’ hypothesis ...

Hydrothermal waters enriched in silica promote the development of a sponge community in North Sulawesi (Indonesia)

open access: yesThe European Zoological Journal, 2017
Two shallow hydrothermal vents were investigated by SCUBA diving to evaluate their influence on the structure and diversity of a sponge community living close to the vent outflow, in the equatorial Pacific Ocean just off the coast of North Sulawesi ...

The mitochondrial genomes of sponges provide evidence for multiple invasions by Repetitive Hairpin-forming Elements (RHE) [PDF]

open access: yes, 2009
Background: The mitochondrial (mt) genomes of sponges possess a variety of features, which appear to be intermediate between those of Eumetazoa and non-metazoan opisthokonts.

On the Influence of Vulnerable Marine Ecosystem Habitats on Peracarid Crustacean Assemblages in the Northwest Atlantic Fisheries Organisation Regulatory Area

open access: yesFrontiers in Marine Science, 2019
Vulnerable marine ecosystems (VMEs) are considered hotspots of biodiversity and ecosystem functioning in the deep sea, but are also characterised by a high vulnerability to disturbance and a low recovery potential.

The role of cell replacement in benthic–pelagic coupling by suspension feeders [PDF]

open access: yesRoyal Society Open Science, 2016
Benthic–pelagic coupling through suspension feeders and their detrital pathways is integral to carbon transport in oceans. In food-poor ecosystems however, a novel mechanism of carbon recycling has been proposed that involves direct uptake of dissolved ...
