Lineage sorting has been suggested as a major force in generating incongruent phylogenetic signal when multiple gene partitions are examined. The degree of lineage sorting can be estimated using the coalescent process and simulation studies have also pointed to a major role for incomplete lineage sorting as a factor in phylogenetic inference. Some recent(More)
Whole genome resequencing of 51 Populus nigra (L.) individuals from across Western Europe was performed using Illumina platforms. A total number of 1 878 727 SNPs distributed along the P. nigra reference sequence were identified. The SNP calling accuracy was validated with Sanger sequencing. SNPs were selected within 14 previously identified QTL regions,(More)
The phylogeny of the paper wasp genus Polistes is investigated using morphological and behavioural characters, as well as molecular data from six genes (COI, 12S, 16S, 28S, H3, and EF1-a). The results are used to investigate the following evolutionary hypotheses about the genus: (i) that Polistes first evolved in Southeast Asia, (ii) that dispersal to the(More)
For many organisms, choosing an appropriate nest site is a critical component of reproductive fitness. Here we examine nest site selection in the solitary, resource defense polygynous bee, Anthidium manicatum. Using a wood-framed screen enclosure outfitted with food sources, nesting materials, and bamboo trap nests, we show that female bees prefer to(More)
