Proposal for a revised classification of the Demospongiae (Porifera)
TLDR
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.
Congruence between nuclear and mitochondrial genes in Demospongiae: a new hypothesis for relationships within the G4 clade (Porifera: Demospongiae).
TLDR
This is the largest and most comprehensive study of the Demospongiae G4 clade and confirms the polyphyly of Halichondrida, Hadromerida, Dictyonellidae, Axinellidae and Poecilosclerida and shows that several of the characters used in morphological classifications are homoplasious.
Revisions to the Classification, Nomenclature, and Diversity of Eukaryotes
TLDR
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.
Phylogeny and systematics of demospongiae in light of new small-subunit ribosomal DNA (18S) sequences.
TLDR
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.
Nearly complete 28S rRNA gene sequences confirm new hypotheses of sponge evolution.
TLDR
Analysis of over 300 nearly complete 28S ribosomal subunit gene sequences provide specific case studies that illustrate how the dataset confirms new hypotheses of sponge evolution, and provides further support for a revision of the traditional classification of sponges.
Molecular phylogenies support homoplasy of multiple morphological characters used in the taxonomy of Heteroscleromorpha (Porifera: Demospongiae).
TLDR
The results show that axially condensed skeletons, asters, acanthostyles, and sigmata are all homoplasious characters, which explains much of the incongruence between molecular-based and morphology-based phylogenies.
Genetic divergence and cryptic speciation in two morphs of the common subtidal nudibranch Doto coronata (Opisthobranchia: Dendronotacea: Dotoidae) from the northern Irish Sea
TLDR
Electrophoretic techniques were used to investigate genetic differentiation between 2 morphologically distinct samples of D. coronata found feeding on 2 different hydroid species off the south west of the Isle of Man (Irish Sea), and results showed extensive genetic differentiation and indicate that the 2 morphs are separate species.
Polymastiidae (Demospongiae: Hadromerida) with ornamented exotyles: a review of morphological affinities and description of a new genus and three new species
TLDR
The present study provides a background for future integrative phylogenetic analyses based on comprehensive molecular and morphological datasets which should reveal the natural relationships between the polymastiid taxa.
Redescription of the type species of the genus Polymastia Bowerbank, 1864 (Porifera, Demospongiae, Hadromerida)
TLDR
Cette Polymastia commune correspond aPolymastia (Spongia) penicillus (Montagu, 1818) d'apres le reexamen d'un specimen de Montagu (depose au BMNH 30.7.3.26 dans le Cabinet du Dr Grant).
