Threat analysis for the Crau Plain Grasshopper (Prionotropis rhodanica)
Although insects represent the most species-rich taxonomic group, providing valuable ecosystem functions and services, their consideration in nature conservation is scarce. One insect species that recently received more attention in conservation is the Crau Plain Grasshopper, Prionotropis rhodanica. This grasshopper is endemic to the Crau plain, a Mediterranean stone steppe in southern France. It strongly declined during the last decade and is therefore listed as Critically Endangered on the IUCN Red List of Threatened Species. In 2014, a conservation strategy for the species has been developed under the supervision of the Species Conservation Planning Sub-Committee (SCPSC) and the Invertebrate Conservation Sub-Committee (ICSC) of the International Union for Conservation of Nature (IUCN) involving the key stakeholders of the area. The strategic plan for the Crau Plain Grasshopper includes several research targets, which mainly form the subject of the PhD project. The PhD project focuses on population ecology (mark-recapture analyses, microhabitat analyses), population genetics (microsatellites, comparison of the present situation with genetic data from samples collected before the population declined) and threat analysis (experiments relating to the aspects predation risk and the effect of sheep medication).
