EXPRESSE-BIOCAM project

This internship looked at the biodiversity of temporary Mediterranean ponds using environmental DNA analyses, targeting bacteria and eukaryotes. The study revealed that factors such as salinity, temperature and human impact influence diversity at different spatial scales. However, no clear link was found between biodiversity and the decomposition of organic matter. Spatial analysis proved relevant, but remote sensing was unable to detect hydroperiods effectively. These results underline the importance of spatialised and integrative approaches to better understand these vulnerable ecosystems..

This course explores zoonotic risks in the Camargue by studying the diversity of pathogens, parasites and vectors (PPV) in different environments. The analysis highlights the influence of environmental factors (temperature, salinity, land use, human impact) on the distribution of PPVs. Some notable pathogens, such as Coxiella burnetii were detected. The results also highlight the importance of future monitoring of antimicrobial resistance. This research is helping us to better anticipate health risks in this area of high ecological and agricultural importance..

(Course from 06/01/2025 to 27/06/2025)

The aim of this course is to document ecological transitions in the Camargue. It is based mainly on two methodological approaches: a literature review and semi-structured interviews. It began with an in-depth review of the scientific and grey literature in order to update our knowledge of the dynamics of ecological transitions. This phase also enabled us to identify the associated public policies and approaches. Interviews will then be conducted with local stakeholders to gather their views, motivations and experiences regarding the transitions underway. These interviews will be transcribed in full and analysed qualitatively. This work requires a reflective and interdisciplinary approach. This will contribute to a better understanding of territorial trajectories and the means of measuring them. This internship will also strengthen the project's capacity to structure a research base for long-term monitoring of transitions.
