Última Diversité et différentiation génétiques des populations de tortues vertes (Chelonia mydas) dans les sites de ponte et d'alimentation du sud-ouest de l'océan Indien : application aux stratégies de conservation de l'espèce ArchiMer Taquet, Coralie. The green turtle (Chelonia mydas) is an emblematic species of marine life. However, nowadays it is subject to many threats (poaching, by-catch). Even if there is deep growing measures for its protection, the green turtle still is an endangered species and it is listed in Appendix I of Washington Convention (CITES). In order to elaborate efficient conservation and management plans, perfect knowledge of green turtle biology, but also of its population structure and their characteristics, are needed. In this thesis, we have assessed genetic structure of green turtle populations in the South-Western Indian Ocean by using genetic tools. In all, 1551 tissue samples have been collected from our study zone and from our control site French Polynesia (37 samples)....

Ano: 2007 URL: http://archimer.ifremer.fr/doc/2007/these-3532.pdf Large spatial scale variation of demersal fish assemblage structure on the continental shelf of the NW Mediterranean Sea ArchiMer Gaertner, J; Bertrand, Jacques; De Sola, L; Durbec, J; Ferrandis, E; Souplet, Arnauld. The spatial structure of demersal fish assemblages on the continental shelf of the NW Mediterranean Sea was examined on a large scale between the Straits of Gibraltar and the Gulf of Lions. In contrast to its predominant role in the spatial distribution of species composition, described worldwide, it seems depth has only a limited effect on the distribution patterns of the total abundance and diversity of demersal fishes. In addition, evidence is provided for the division of the whole study area into 3 geographical fish assemblages. The influence of Atlantic inputs and the semi-permanent Almena-Oran hydrographic front play a key role in defining the Alboran Sea as a specific fish fauna area. Moreover, the clear differentiation between 2 distinct... Tipo: Text Palavras-chave: Mediterranean Sea; Management units; Species diversity; Assemblage structure; Demersal fishes. Ano: 2005 URL: http://archimer.ifremer.fr/doc/2005/publication-3623.pdf Structure et connectivité de la mégafaune marine à l’échelle d’une région océanique. 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...
