Importance of assessing population genetic structure before eradication of invasive species: examples form insular Norway rat populations
International audience Determining the inter-island migration abilities of pest species and delimiting eradication units enable more viable long-term eradication campaigns because recurrent colonization from neigbboring islands is avoided. We examined the genetic structure of the invasive Norway rat...
