The aims
40 20 1
Phylogeny of Myriapora truncata Cryptic species? Phylogeography with sampling of the Eastern Mediterranean Sea
And check for possible morphologic differences between the haplotype groups and profiles.
H1 Analysis in process
- the size and the thickness of the operculum - the space between neighbouring zooids - the skeleton's structure
H3
Study of the connectivity Effects of ecologic parameters? 10 km
Material and Methods Sampling of about thirty fragments on each site at 28±1 m depth, distributed on two different profiles. Genetic analysis with the amplification of a mitochondrial marker (COI) and a nuclear marker (EPIC i21).
3 haplotype groups: cryptic species?

CIGESMED and the Coralligenous The Coralligenous habitat is a whole set of mediterranean ecosystems and habitats which are important in terms of complexity and biodiversity. It provides protection and feeding area to many species. In this context, the European program CIGESMED studies the Good Environmental Status of this habitat focusing on the ecology and the genetic of biobuilders species such as Lithophyllum spp. and Myriapora truncata.
