Species of Tetillidae are distributed worldwide. However, some genera are unresolved and only a few genera and species of this family have been described from the Antarctic. The incorporation of 25 new COI and 18S sequences of Antarctic Tetillidae to those used recently for assessing the genera phylogeny, has allowed us to improve the resolution of some poorly resolved nodes and to confirm the monophyly of previously identified clades. Classical genera such as Craniella recovered their… Expand
Patterns of genetic and morphologic diversity in antarctic sponges
TLDR
The present thesis contributed to improve the systematic of an Antarctic sponge group and its phylogenetic relationships with other members of the family (Tetillidae) spread all over the world, and to assess the asexual reproduction rate of an Antarctica sponge species (Stylocordyla chupachups). Expand
Molecular phylogenies confirm the presence of two cryptic Hemimycale species in the Mediterranean and reveal the polyphyly of the genera Crella and Hemimycale (Demospongiae: Poecilosclerida)
TLDR
A phylogenetic study of Hemimycale columella across the Mediterranean suggested larger genetic differences than those expected between sponge populations, and confirmed that unidentified cryptic species may confound ecological studies. Expand
Unravelling the moons: review of the genera Paratetilla and Cinachyrella in the Indo-Pacific (Demospongiae, Tetractinellida, Tetillidae)
Abstract Paratetillabacca (Selenka, 1867) and Cinachyrellaaustraliensis (Carter, 1886) occur in a broad range of marine environments and are allegedly widely distributed species in the Indo-Pacific.Expand
Seven new deep-water Tetractinellida (Porifera: Demospongiae) from the Galápagos Islands – morphological descriptions and DNA barcodes
TLDR
Phylogenetic reconstructions combining independent markers (mtDNA and rDNA) support the generic affiliation of these new species and confirm the separation of Eastern Pacific species from Caribbean and Central to West Pacific species. Expand
Development of a multilocus-based approach for sponge (phylum Porifera) identification: refinement and limitations
For sponges (phylum Porifera), there is no reliable molecular protocol available for species identification. To address this gap, we developed a multilocus-based Sponge Identification Protocol (SIP)Expand
Divergence times in demosponges (Porifera): first insights from new mitogenomes and the inclusion of fossils in a birth-death clock model
TLDR
This study assembled mitochondrial genomes of six desma-bearing demosponges from size-selected reduced-representation genomic libraries and applied a fossilized birth-death model including 30 fossils and 33 complete demosponge mitochondrial genomes to infer a dated phylogeny of Demospongiae, which supports a Neoproterozoic origin. Expand
Divergence times in demosponges (Porifera): first insights from new mitogenomes and the inclusion of fossils in a birth-death clock model
TLDR
This study uses desma-bearing sponges, a diverse group of demosponges that form rigid skeletons and have a rich and continuous fossil record dating back to the Cambrian, to date the demosponge radiation and constrain the timing of key evolutionary events, like the transition from marine to freshwater habitats. Expand
Systematics of ‘lithistid’ tetractinellid demosponges from the Tropical Western Atlantic—implications for phylodiversity and bathymetric distribution
TLDR
This first integrative approach of TWA ‘lithistid’ demosponges contributes to a better understanding of their phylogenetic affinities, diversity and bathymetric distribution patterns within the TWA. Expand
First records of Geodia demosponges from the New England seamounts, an opportunity to test the use of DNA mini-barcodes on museum specimens
TLDR
Advances in mini-barcodes on formalin-fixed or old specimens with degraded DNA are advocated, by advocating the use of mini- barcodes in response to the growing need for accurate identification of deep-sea amphi-Atlantic sponge species. Expand
Evolution of group I introns in Porifera: new evidence for intron mobility and implications for DNA barcoding
TLDR
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

Phylogeny of Tetillidae (Porifera, Demospongiae, Spirophorida) based on three molecular markers.
TLDR
The phylogenetic analysis supports the monophyly of Tetilla, a genus lacking any known morphological synapomorphy, and the common view that assumes close relationships among sponges with porocalices (i.e., surface depressions) is refuted. Expand
Nuclear and mitochondrial phylogeny of Rossella (Hexactinellida: Lyssacinosida, Rossellidae): a species and a species flock in the Southern Ocean
TLDR
A molecular phylogenetic analysis of the genus Rossella, based on mitochondrial (16S rDNA and COI) and nuclear (28S r DNA) markers, corroborate the monophyly of RossellA and provide evidence supporting the existence of one species. 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
An unprecedented new genus and family of Tetractinellida (Porifera, Demospongiae) from New Zealand's Colville Ridge, with a new type of mitochondrial group I intron
TLDR
The phylogenetic affinity and taxonomic position of this unique sponge is explored in relation to a broad range of tetractinellid sponges using the Folmer’+ Erpenbeck fragment of the cytochrome c oxidase subunit I (COI) gene and a nearly complete sequence of the 18S rDNA gene. Expand
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. Expand
Tetillidae (Spirophorida, Porifera): a taxonomic reevaluation
TLDR
The study led to a reevaluation of genera in that family, as well as of characters used to distinguish species, and to examine additional biological and molecular biological properties of the sponges for possible application in taxonomy. Expand
Reconstructing ordinal relationships in the Demospongiae using mitochondrial genomic data.
TLDR
This work assembled a mitochondrial genomic dataset comprising all orders of demosponges that includes 17 new and five previously published complete demosponge mitochondrial genomes and assembled a modified method for the analysis of gene order data that works well when translocation of tRNA genes are more frequent than other rearrangements.

The phylogenetic relationships of nine species of freshwater sponges, representing the families Spongillidae, Lubomirskiidae, and Metaniidae, were inferred from analyses of 18S rDNA, cytochromeExpand
Molecular phylogeny of Demospongiae: implications for classification and scenarios of character evolution.
TLDR
The topology derived from molecular data provides a basis for proposing a new classification of Demospongiae s.s., and suggests a reverse polarity of some characters, with respect to traditional conceptions: viviparity, presence of monaxon spicules and of spongin appear to be ancestral, whereas ovip parity, and presence of tetraxon spicule appear as derived characters.

New genus and species of Polymastiidae (Demospongiae: Hadromerida) from the Antarctic deep sea
TLDR
Astrotylostyles of Astrotylus, cladotylostyles of Tylexocladus and grapnel-like exotyles of Proteleia may be the remnants of non-monaxonic ancestral spicule type in Polymastiidae that calls for reconsideration of the relations between hadromerid families. Expand
