Molecular phylogeny and taxonomy of the Astrophorida (Porifera: Demospongiae).

Although the phylum Porifera (sponges) embodies an important step in metazoan evolution (the first), its phylogeny is poorly resolved. The order Astrophorida encompasses around 660 species worldwide, some of which are of importance for their pharmaceutical properties. To date, morphological data has not been able to reveal the inter and intra-family relationships of that order. My Ph.D proposes to resolve the relationships amongst the Astrophorida using independent data sets from molecular sequences. A reassessment of the North-East Atlantic Astrophorida is also one of my projects.
