Genetic and taxonomic assessment of the widespread Afrotropical ambrosia beetle Xyleborus principalis (Coleoptera, Scolytinae)
Jordal, Bjarte Henry; Tischer, Marta (Journal article; Peer reviewed, 2020)The taxonomy of the widespread Afrotropical ambrosia beetle Xyleborus principalis Eichhoff, 1878 is reviewed based on morphological and molecular data. The species is both morphologically and genetically variable but without ... -
Genomic mining of phylogenetically informative nuclear markers in bark and ambrosia beetles
Pistone, Dario; Mugu, Sigrid; Jordal, Bjarte Henry (Peer reviewed; Journal article, 2016-09-26)Deep level insect relationships are generally difficult to resolve, especially within taxa of the most diverse and species rich holometabolous orders. In beetles, the major diversity occurs in the Phytophaga, including ... -
Globally distributed Xyleborus species reveal recurrent intercontinental dispersal in a landscape of ancient worldwide distributions Phylogenetics and phylogeography
Gohli, Jostein; Selvarajah, Tina; Kirkendall, Lawrence R.; Jordal, Bjarte Henry (Peer reviewed; Journal article, 2016-02-15)Background: Invasive species can have devastating effects on native ecosystems and therefore impose a significant threat to human welfare. The introduction rate of invasive species has accelerated dramatically in recent ... -
