Offer Description

Coastal ecosystems are naturally exposed to spatial and temporal variations in salinity. They are also subject to secondary salinization linked to the consequences of anthropogenic activities, due to various processes such as sea-level rise, increased intensity and frequency of marine submersions, or changes in precipitation and temperature that will affect freshwater inputs and increase evaporation. All these processes and the associated increase in salinity can influence species distribution, community diversity and structure, and radically transform coastal ecosystems and their functionality. The aim of this post-doctoral contract is to understand how the salinization of coastal wetlands influences the ecology and physiology of vertebrate populations (amphibians) of major conservation interest. This work focuses on long-term monitoring of salinity (since 1996), coupled with long-term monitoring of amphibian populations (labelled SEE-Life by CNRS Ecologie et Environnement) in the Brouage marsh. It also benefits from similar monitoring on other coastal marshes (RNN de La Belle Henriette, RNN des Marais d'Yves), enabling these effects to be approached on a wider geographical scale and from a comparative point of view.
This post-doctoral contract will enable us to understand the combined effects of salinity and other environmental stressors, such as environmental contamination and temperature increase, in order to understand the consequences of ongoing environmental changes in coastal wetlands.

- Data collection in the field and under controlled laboratory conditions
- Data analysis and valorization
- Interaction with the managers of the National Nature Reserves involved

Already available datasets can be analyzed and published during the post-doctoral contract :
- assessment of demographic parameters (based on mark-recapture monitoring) of Pelobates cultripèdes populations along a spatial salinity gradient,
- study of the small-scale genetic structure (microsatellites) of the same populations of Pelobates cultripèdes,
- assessment of the temporal and spatial dynamics of soil salinity based on samples collected over the last two years.

Other research questions may be explored in the context of the effects of coastal salinization on amphibian ecology and physiology (ecophysiological responses, sensitivity to pathogens, multi-stress effects).

The CEBC is located in the southern Deux-Sèvres not far from Niort and La Rochelle. This laboratory (UMR 7372 CNRS and La Rochelle University) focuses on the mechanisms and processes that regulate biodiversity dynamics. The Ecophy team studies wildlife responses to environmental stressors, integrating the underlying ecological and physiological mechanisms. The post-doctorate will be supervised by François Brischoux (DR CNRS) as part of the interdisciplinary Observatoire des Marais de Brouage project.

Expertise in ecology and/or ecophysiology,
Expertise in sample and data collection on wildlife in the field and at the laboratory,
Expertise in data analyses and scientific writing,
Good interpersonal skills with academic and non-academic partners,
Dynamism, initiative, creativity.
