Diversity of Porifera in the Mediterranean coralligenous accretions, with description of a new species

The obtained data increase to 273 the number of sponge species associated with the coralligenous concretions and confirm that this habitat is an extraordinary reservoir of biodiversity still largely unexplored, not only taxonomically, but also as to peculiar adaptations and life histories.

Phylogenetic Reassessment of Antarctic Tetillidae (Demospongiae, Tetractinellida) Reveals New Genera and Genetic Similarity among Morphologically Distinct Species

The incorporation of 25 new COI and 18S sequences of Antarctic Tetillidae to those used recently for assessing the genera phylogeny has allowed the resolution of some poorly resolved nodes and to confirm the monophyly of previously identified clades.

Asexual reproduction and heterozygote selection in an Antarctic demosponge (Stylocordyla chupachus, Suberitida)

To analyze the weight of clonal reproduction in the species, a genetic study was performed on three close populations using eight polymorphic microsatellite loci that were designed from massive sequencing, which suggests a positive selection mechanism for heterozygotes.

Correction: Phylogenetic Reassessment of Antarctic Tetillidae (Demospongiae, Tetractinellida) Reveals New Genera and Genetic Similarity among Morphologically Distinct Species

This research presents a novel probabilistic approach to estimating the response of the immune system to laser-spot assisted, 3D image analysis of central nervous system injury.

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).

Description of two new genera (Antarctotetilla, Levantiniella) and a new species of Tetillidae.

This study aims to re-describe in detail the species of Tetillidae that belong in the two above mentioned new genera, and to highlight that molecular phylogenies should be combined with morphological analyses to improve taxonomical decisions.
