Spatial Variation In The Genetics, Ecology And Life-History Of A Marine Species Interaction. The Case Of The Striped Seabream Lithognathus Mormyrus And The Parasitic Isopod Cerathotoa Italica
Biodiversity is described as the variety of all forms of life that can be identified at a genetic, ecological, and organismal level. Intra-species biodiversity encompasses variation at all these levels due to the intrinsic and the extrinsic characteristics of each organism. This project uses a multidisciplinary approach to unveil differentiation patterns of intra species diversity along a geographical range. I employed mitochondrial DNA markers to unravel historical differentiation, and nuclear markers (microsatellites), life history parameters, parasitic fauna, and host parasite interactions to depict the contemporary patterns of population differentiation in the warm-temperate coastal marine teleost Litognathus mormyrus.
