Última Relationships between sediments and tissue contamination and allozymic patterns in Hediste diversicolor (Polychaeta Nereididae) in the Pialassa lagoons (north Adriatic Sea) ArchiMer Virgilio, M; Baroncini, N; Trombini, C; Abbiati, M. An increasing number of investigations revealed that responses of populations to environmental stressors may be genetically dependent. Occurrence of genetic adaptation to high concentrations of heavy metals in Hediste diversicolor local ecotypes has also been hypothesised. Analyses of allozymic patterns are a promising tool for the genetic monitoring of environmental stressors. The aim of this study was to investigate whether the allozymic patterns of H. diversicolor could be affected by levels of contamination. Five sites were investigated: four in a polluted brackish habitat, the Pialassa lagoons, and a reference site in the Lamone estuary. Total mercury was used as a tracer of the overall level of contamination. Concentrations of mercury were quantified...

Enjeux pour la gestion durable des tortues vertes dans l’océan Indien occidental ArchiMer Bourjea, Jerome. This thesis is a comprehensive work aiming to improve scientific knowledge on the green turtle (Chelonia mydas) in order to provide key scientific evidences needed for the implementation of coherent and effective management measures to protect at the Western Indian Ocean scale this threatened species. In a first step, this work aimed to established baseline data on the abundance of green turtles nesting females and long term trends of some key nesting populations of the region by applying different modelling methods. In a second step, this work determined the regional genetic structure of this species and the relationships that exists between the different populations. Finally, the conservation of marine turtles being closely dependant to external...
