Post-doc position : ISIT_U : In search of isotopic uncertainties in ecology using food web dynamic modelling
The present project deals with the improvement of a widely used tool in ecology, i.e. stable isotope analysis (SIA), by a better understanding of the underlying mechanisms and by a greater account taken of its incorporation into trophic ecology. Living organisms interact by means of predator-prey relationships within food webs. These control most ecological processes directly or indirectly. Improving SIA methods at different biological organisational levels allows to better monitor how global change affects biodiversity and ecosystem functioning (climate regulation, food supply etc…) in a multifactorial way. Primary focus will be on marine species and marine ecosystems but could be extended to terrestrial species and ecosystems for comparison purposes. For example, a database on marine and freshwater fishes has been already completed. The project is fundamental, yet the impact on the scientific community will be direct thanks to the development of R packages that will be made freely available.
