Sponges from the Kara Sea (Arctic Russia) collected by the Dutch Polar Expedition 1882-83 are identified and discussed. The expedition experienced an unfortunate course of events, as the research vessel RV ’Varna’ was ice-bound and eventually got

Benthic surveys were conducted on submerged lava beds of varying age off the east coast of Reunion in 2011. Scuba-mediated collecting and photography was undertaken within depth zones at 10 sites on four pre-1977 lava beds and those formed in 1977, 2

A comparison is made of sponge diversity and abundance in nine cold-water coral reef locations situated in four regions of the north-east Atlantic, Rockall Bank (two reef locations, both deep, oceanic), Porcupine Bank (two locations, both deep, ocean

This study describes species of the genusHymedesmiafrom three areas of cold-water coral reef: Mingulay Reef Complex (Scotland, UK) and Rockall and Porcupine Banks (off UK and Irish coasts). Five new species are described:Hymedesmia (Hymedesmia) gibbo

Sponge communities found in Caribbean mangroves are typical to this habitat: partly endemic and very distinct from sponge communities on nearby reefs. A trade-off between resistance to competitors and predators appears to influence success of individ

In this study we assessed the sequence variation in the I3-M11 partition of the mtDNA cytochrome c oxidase subunit I gene (COI) in ten populations of the Atlanto-Mediterranean demosponge Phorbas fictitius (Porifera: Poecilosclerida) at two spatial sc

Carbon-supported catalysts containing Cu and Cr are active in oxidation and reduction reactions. In CO oxidation experiments, an activity hysteresis has been observed for the Cu/Cr-carbon catalyst during temperature cycling. From results of CO oxidat

Over the past several decades molecular tools have shown an enormous potential to aid in the clarification of species boundaries in the marine realm, particularly in morphologically simple groups. In this paper we report a case of cryptic speciation

Sponges are an integral part of marine benthic communities with a high-impact role in benthic–pelagic coupling processes, as an important source of food for demersal grazers and predators, as hosts of a highly diverse microbial biomass, and as bio-
