To improve control strategies against pests and identify means of conserving threatened natural populations, it is vital to modify the constraints to which they are subject, and thus to analyse the constraints on each set of organisms, and how those organisms adapt to changes in the constraints.
The CBGP aims to understand the mechanisms that govern populations of organisms that are important to agriculture, the environment and human health. Its studies concern various types of organisms: rodents, toads, insects, mites, nematodes, pathogens of those invertebrates and complexes of organisms that are harmful to crops. It studies population structure within species, complexes of species and communities, whose interactions are governed by selection pressure and the environment. The information sought concerns the characterization of the genetic systems involved, the analysis of how they interact, and the determinism of their ability to adapt in a range of environmental situations.
