Description of the thesis topic

PhD position « Crustaceans: a tool for describing prehistoric human behaviour and palaeoenvironments in a maritime context in Atlantic Europe »
The subject of the thesis is multidisciplinary. It will lead the candidate to work in biology and in archaeology. Methodological developments in archaeology have made visible elements that have long been ignored by archaeologists. Amongst these, for crustaceans, the tips of crab fingers are the most recurrent for decapod crustaceans. The candidate will work on this material. It size is most often on a sub-centimetre scale.
The thesis project is structured in three stages:
- The first stage consists of completing the CReAAH's collection of modern crabs. The chosen species are those available on the studied area.
- The second stage consists of studying archaeological remains of crabs. It is dependent on the quality of the excavations. It includes the sorting, quantification, identification and metrics of archaeocarcinological remains from northern Scandinavia to southern Portugal (Palaeolithic to Neolithic). The challenges of this second stage is the unprecedented description of crabs transported and exploited by prehistoric populations.
- The third stage of the doctoral project aims to compare archaeological data in diachronic terms from the Palaeolithic to the Neolithic and to modern data. The distribution of species, their proportions and the size of individuals will be studied.
The candidate will benefit from the support of the expertise in the analysis of marine invertebrates in archaeology of the CReAAH (Centre de Recherche en Archéologie, Archéosciences et Histoire). Several of the collections to be analysed are the result of research by the laboratory's archaeologists. The CReAAH has made the analysis of marine invertebrates a specificity that is internationally recognised. The candidate will also benefit from the support of LEMAR (Laboratoire des sciences de l'Environnement MARin). This laboratory is internationally known in the field of marine sciences. Among other things, it monitors the biodiversity of marine species, including invertebrates, along the Atlantic coastline in the face of global change.

Work Context

This project is supported by the Gdr Omer of the MITI (CNRS). It leads the candidate to work in biology and in archaeology. This double competence of the thesis project is supported by two laboratories: thesis director Catherine Dupont CReAAH / thesis co-director Jacques Grall LEMAR. The thesis is interdisciplinary. It will be based in Rennes at CReAAH. The candidate will benefit from all the facilities of the "Malacology and marine invertebrates" technical platform of the LAGO research platform (Laboratoire Archéosciences Grand Ouest). Travel will be required to the coast in order to complete the comparison collection and to the partner countries to sort crabs from archaeological sediments.
In addition to the projects already mentioned, this thesis forms part of the themes of the "Archaeology of coastal, maritime and fluvial spaces" team of the CReAAH, Rennes. The candidate will be integrated into this research team. He/she will be able to participate in the OSUR's "Natural Resources" research axis. Similarly, at the Brest level, it is in phase with the themes of the LEMAR, including "Marine ecology: diversity, structure and dynamics of populations and communities" and the IUEM, including "Marine ecosystems and biodiversity" and "The coastline, a complex and fragile interface".

Constraints and risks

Desired profile
The candidate must have a Masters degree or equivalent. The position requires excellent observation skills, a strong curiosity and an affinity with marine fauna and environments.

Additional Information

The doctorate requires an analytical mind and an ability to synthesise information, the ability to work autonomously while favouring fluid and efficient communication in order to promote the progress of the research project, a very good capacity to work in a team, a good command of English (written and oral in order to communicate with other young researchers, to write scientific papers and to participate in international conferences). The candidate will have to show a strong motivation to complete his/her PhD and a strong involvement in his/her thesis subject (training to acquire new skills, bibliographic watch...).

Applications must include:
- a detailed CV
- cover letter of one page
- grades for the Masters 1 or 2
