The symposium will cover the description, understanding and prediction of the spatial distribution of genetic diversity within Orthopteran species.
This would include tracing back the demographic history of populations (population size changes, dating of divergence and mixing episodes, etc.) and analyzing the evolutionary processes driving spatial patterns, in a changing environment, considering pressures of biotic (host plant, parasitoid, microbial communities) and non-biotic selection (climate, land use, agricultural practices).
The scope of the symposium will be extended to the historic biogeography of supra-specific taxa but at a small evolutionary scale (i.e. within genus).
This symposium will also host studies based on new data obtained from sequencing technologies and high-throughput genotyping (e.g. RAD-Seq).
