dc.description.abstract | Anthropogenic activities (e.g. homogenized habitats, trade) are the main factors to facilitate the increasing rates of invasive alien species. In this study, the invasion of the Asian long-horned beetle (Anoplophora glabripennis) was examined. Its native distribution is eastern Asia (China, Korean peninsula), but by extensive trade, this beetle was introduced via wood packing materials to North-America (1996) and Europe (2001). ALB attacks healthy broadleaved trees (e.g. Acer spp., Salix spp., Populus spp.), which can become lethal due to larval feeding. This study aims to detect genetic differences and kinship between the European infestation sites in Germany, Switzerland and Italy, from which the introduction and dispersal patterns can be deviated. Therefore, mitochondrial (mt) DNA-markers of the Cytochrome oxidase subunits I and II genes (COI and II) were used (ch. A and B, Sanger sequencing), as well as genome wide single nucleotide polymorphisms (SNPs), which were obtained by a Genotype-by-sequencing (GBS) approach (ch. C, Illumina sequencing). The results of this population genomic study of invasive European ALB populations showed very complex introduction patterns into Europe including multiple independent introductions characterized by the high population structure between the European infestation sites and some cases of human mediated secondary dispersal. | en |
dc.description.abstract | Anthropogene Aktivitäten (z.B. homogenisierte Habitate, Handel) sind die Hauptfaktoren, die ein erhöhtes Vorkommen invasiver Arten begünstigen. Diese Studie untersuchte die Invasion des Asiatischen Laubholzbockkäfers (Anoplophora glabripennis). Sein natürlicher Lebensraum liegt in China und der koreanischen Halbinsel und konnte durch intensiven Handel über Holzverpackungsmaterial nach Nordamerika (1996) und Europa (2001) eingeschleppt werden. ALB befällt gesunde Laubbäume (z.B. Acer spp., Salix spp., Populus spp.) was durch den Larvenfraß oft tödlich enden kann. Ziel dieser Arbeit war es, genetische Unterschiede von Befallsgebieten in Deutschland, der Schweiz und Italien zu finden, um Verwandtschaften und damit Einschleppungs- und Verbreitungswege abzuleiten. Dafür wurden mtDNA-Marker der Cytochromoxidase Untereinheiten I und II (Kap. A und B, Sanger Sequenzierung,) und durch Genotype-by-sequencing (GBS) gewonnene genomweite Einzelnukleotidpolymorphismen (SNPs) verwendet (Kap. C, Illumina Sequenzierung). Die Ergebnisse der populationsgenomischen Untersuchung invasiver ALB Populationen in Europa zeigen sehr komplexe Einschleppungswege, bestehend aus mehreren unabhängigen Einfuhren, die sich durch die starke Populationsstruktur zwischen den europäischen Befallsgebieten auszeichnen, sowie einzelnen Fällen von sekundärer Verbringung durch den Menschen. | de |
