Thesis subject:
Conservation of a very rare annual fugitive species: Lythrum thesioides.
Lythrum thesioides is a very rare annual species, which has been observed in only two wetlands in the world, both in the Gard Department in France. The most significant population was discovered in 2010, during the impact study for the high speed train line to be built between Nîmes and Montpellier. My research focuses on this specific population. My goal is to improve our knowledge of the species’ biology, and of this population in particular, so that we can define management practices that will ensure its conservation.
In particular my research focuses on:
- The germination ecology of thesioides and other annual Lythrum found in Mediterranean temporary ponds;
- A seed bank study;
- A study of the ecological niche of annual Lythrum that includes plant surveys and the experimental management of wetlands.
Expertise
- The ecology of temporary Mediterranean ponds
- Conservation of plant populations and species
