Impact of the Carpathians on the genetic structure of the spruce bark beetle Ips typographus

摘要: The Carpathians are a range of mountains forming an arc roughly 1,500 km long across Central and Eastern Europe. They important area for biodiversity belong to one the major refuges last ice ages many organisms. forests dominated by spruce, which have suffered continuous outbreaks eight spined spruce bark beetle, Ips typographus, in recent decades. phylogeography this pest is well documented, however, little known on small scale, i.e., Carpathians. Here we applied mitochondrial marker studied genetic variation structure Carpathian populations compared data with published from other European populations. Twelve haplotypes were characterized 42 % those not detected Despite slight structure, differences observed haplotype distribution diversity between Western/Southern reflecting at least two potential refugial areas I. typographus within mountain system. Further show that Beskidian Mountains could act as barrier several haplotypes. This small-scale analysis reveals been glacial post-glacial refuge typographus. information preventive reactive forest management.
