Proposal for a revised classification of the Demospongiae (Porifera)
The deletion of polyphyletic taxa, the use of resurrected or new names for new clades and the proposal of new family groupings will improve the comparability of studies in a wide range of scientific fields using sponges as their object of study. Expand
Sponge systematics facing new challenges.
A review of the taxonomic changes since the publication of the Systema Porifera (2002) is presented, and problems a sponge taxonomist is still faced with nowadays are pointed to. Expand
Phylogeny and systematics of demospongiae in light of new small-subunit ribosomal DNA (18S) sequences.
This study targets representation of type species and genera that have never been sampled for any molecular data in an effort to accelerate progress in classifying this diverse lineage of Demospongiae. Expand
Revisions to the Classification, Nomenclature, and Diversity of Eukaryotes
It is confirmed that eukaryotes form at least two domains, the loss of monophyly in the Excavata, robust support for the Haptista and Cryptista, and suggested primer sets for DNA sequences from environmental samples that are effective for each clade are provided. Expand
Taxonomy, biogeography and DNA barcodes of Geodia species (Porifera, Demospongiae, Tetractinellida) in the Atlantic boreo-arctic region
Geodia species north of 60 degrees N in the Atlantic appeared in the literature for the first time when Bowerbank described Geodia barretti and G.macandrewii in 1858 from western Norway. Since thenExpand
No longer Demospongiae: Homoscleromorpha formal nomination as a fourth class of Porifera
Within the currently more widely accepted hypothesis of a monophyletic Porifera, it is formally proposed here to raise Homoscleromorpha to the class rank (the fourth one), following the PhyloCode. Expand
Molecular Phylogeny of the Astrophorida (Porifera, Demospongiae p) Reveals an Unexpected High Level of Spicule Homoplasy
The Astrophorida is a larger order than previously considered, comprising ca. Expand
Relationships between Host Phylogeny, Host Type and Bacterial Community Diversity in Cold-Water Coral Reef Sponges
The high diversity of sponge species in cold-water coral reefs, combined with the observed sponge-related variation in bacterial community structure, support the idea that sponges represent heterogeneous, yet structured microbial habitats that contribute significantly to enhancing bacterial diversity in deep-sea ecosystems.

Evolution of group I introns in Porifera: new evidence for intron mobility and implications for DNA barcoding
This study validates the subclass Spirophorina (Tetractinellida) as an intron hotspot in sponges and confirms that most sponge group I introns probably originated from fungi. Expand
Redescription and resurrection of Pachymatisma normani (Demospongiae: Geodiidae), with remarks on the genus Pachymatisma
Using a partial sequence of the cytochrome c oxidase subunit I (COI) and an ITS1-5.8-ITS2 nuclear fragment, it is shown that consistent genetic differences exist between the two species P. johnstonia from P. normani. Expand
