Global Diversity of Sponges (Porifera)
With the completion of a single unified classification, the Systema Porifera (SP) and subsequent development of an online species database, the World Porifera Database (WPD), we are now equipped toExpand

Ecology of Antarctic Marine Sponges: An Overview1
Abstract Sponges are important components of marine benthic communities of Antarctica. Numbers of species are high, within the lower range for tropical latitudes, similar to those in the Arctic, andExpand

Molecular evidence of cryptic speciation in the "cosmopolitan" excavating sponge Cliona celata (Porifera, Clionaidae).
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. InExpand

Phylogenetic Relationships of the Marine Haplosclerida (Phylum Porifera) Employing Ribosomal (28S rRNA) and Mitochondrial (cox1, nad1) Gene Sequence Data
The systematics of the poriferan Order Haplosclerida (Class Demospongiae) has been under scrutiny for a number of years without resolution. Molecular data suggests that the order needs revision atExpand

Global Coordination and Standardisation in Marine Biodiversity through the World Register of Marine Species (WoRMS) and Related Databases
The World Register of Marine Species is an over 90% complete open-access inventory of all marine species names. Here we illustrate the scale of the problems with species names, synonyms, and theirExpand

From anti-fouling to biofilm inhibition: new cytotoxic secondary metabolites from two Indonesian Agelas sponges.
Chemical investigation of Indonesian marine sponges Agelas linnaei and A. nakamurai afforded 24 alkaloid derivatives representing either bromopyrrole or diterpene alkaloids. A. linnaei yielded 16Expand

Isolation of azaspiracid-2 from a marine sponge Echinoclathria sp. as a potent cytotoxin.
Azaspiracid-2 was isolated from a marine sponge Echinoclathria sp. collected off Amami-Oshima as the predominant cytotoxic constituent. A combination of HPLC using ODS, GS320, and PhenylhexylExpand

Speculation with spiculation?--Three independent gene fragments and biochemical characters versus morphology in demosponge higher classification.
Demosponge higher-level systematics is currently a subject of major changes due to the simplicity and paucity of complex morphological characters. Still, sponge classification is primarily based onExpand

Novel polycyclic guanidine alkaloids from two marine sponges of the genus Monanchora.
Two marine sponges of the genus Monanchora (Poecilosclerida, Crambeidae) have been found to contain new polycyclic guanidine alkaloids bearing the (5,6,8b)-triazaperhydroacenaphthylene skeleton.Expand

Horny sponges and their affairs: on the phylogenetic relationships of keratose sponges.
The demosponge orders Dictyoceratida and Dendroceratida are historically assigned to the keratose (or "horny") sponges, which are mostly devoid of primary skeletal elements, but possess an elaborateExpand
