The pinewood nematode Bursaphelenchus xylophilus is a severe pest of coniferous trees, and has been designated as a quarantine organism in the European Union. From the sequence of a satellite DNA family characterized in the genome of this nematode, we developed a PCR procedure that allowed the specific discrimination of this species from...

Population genetics have been greatly beneficial to improve knowledge about biological invasions. Model-based genetic inference methods, such as approximate Bayesian computation (ABC), have brought this improvement to a higher level and are now essential tools to decipher the invasion routes of any invasive species. In this paper, we performed...

Population genetics have been greatly beneficial to improve knowledge about biological invasions. Quantitative genetic methods, such as Approximate Bayesian Computation (ABC), have brought this improvement up a notch and are now essential tools to decipher the invasion routes of any invasive species. In this paper, we performed ABC analyses to...

Tandemly repeated sequences known as satellite DNA (satDNA) generally exhibit complex evolutionary patterns of concerted evolution in which mutations are homogenized and fixed in a stochastic process of molecular drive. Here, the nucleotidic variability of the Mspl satDNA family of the pinewood nematode Bursaphelenchus xylophilus is analyzed in...

The pinewood nematode, Bursaphelenchus xylophilus, native to North America, is the causative agent of pine wilt disease and among the most important invasive forest pests in the East-Asian countries, such as Japan and China. Since 1999, it has been found in Europe in the Iberian Peninsula, where it also causes significant damage. In a previous...

Identifying the invasion routes and determining the origin of new outbreaks of invasive species are of crucial importance if we are to understand the invasion process, improve or establish regulatory measures and, potentially, limit the damage. We focused here on the invasion of Europe by the pinewood nematode (PWN), Bursaphelenchus xylophilus...
