MCCLINTOCK, James B.; AMSLER, Charles D.; BAKER, Bill J.; VAN SOEST, Robert; Univ. of Alabama at Birmingham; Univ. of Alabama at Birmingham; Univ. of South Florida; University of the Netherlands: The Ecology of Antarctic Marine Sponges Sponges are dominant components of marine communities surrounding the continental shelf of Antarctica. High in terms of species diversity […]

JANUSSEN, Dorte; Forschungsinstitut und Naturmuseum Senckenberg: Sponges in deep water: A key to success Deep-sea research utilizing hyperbenthic sampling devices has revealed unexpected high densities and diversity of sponges, and many of the recently collected deep-sea sponges are new species. Selected case studies in the Antarctic, North Atlantic and Mediterranean Sea show that this is […]

REITNER, Joachim; Univ. of Goettingen, Geobiology: Sponges � A geobiological approach Sponges are ancestral metazoans with a great geobiological importance. They are divided in two clades, the silica forming sponges (Hexactinellida & Demospongiae), and the Mg-calcite forming Calcarea. The fossil record trace back 1.8 Mrd.y based on chemofossils. Intriguing is that all main taxa of […]

HOOPER, John N.A.; SOEST, Rob W.M. Van; Queensland Museum, Brisbane; Zoological Museum University of Amsterdam: Sponge biodiversity and biogeography Even if the scope of the phylum Porifera is now better resolved, many features of sponge biodiversity are still poorly understood, including: the magnitude of species diversity, their spatial distributions, mechanisms for recruitment, dispersal and connectivity, […]

PAWLIK, J. R.; Univ. of North Carolina at Wilmington: Is bad taste expensive? Resource allocation and chemical defenses of Caribbean sponges. Sponges are a major component of the benthic fauna of Caribbean reefs, and are consumed by a few species of predatory fishes (e.g., angelfishes). We previously discovered that Caribbean sponge species could be divided […]

NICHOLS, S. A.; University of California, Berkeley: Does the existing classification reflect the relationships within demosponges? A molecular phylogenetic approach. Demosponges are hypothesized to belong to the most basal metazoan clade. The majority of marine sponges and all freshwater sponges are included in the Demospongia. Despite their importance to our understanding of metazoan evolution and […]
