Cartographic Representation of Averaged Pairwise Information (CRAPI): a new exploratory tool to investigate spatial structures illustrated with genetic data from the Watermelon mosaic virus. [O.15] [PDF]
Dedicated analyses in landscape genetics require a priori knowledge on species dispersal abilities. When little is known about the species under study these methods are difficult to apply and, therefore, we rely on exploratory approaches allowing to ...
