A generalist vector-transmitted parasite exhibits population genetic structure among host genera by Vincenzo A. Ellis, Mélanie Duc, Arif Ciloglu, Olof Hellgren, Staffan Bensch

“…We designed a sequence capture protocol to isolate 1.13 Mbp (ca. 5%) of the parasite genome and identified 1399 variable sites among the sequenced infections. In a principal components analysis, infections of Phylloscopus and Sylvia species mostly separated along the first 2 principal components. …”

Symptoms of dwarf elm (Ulmus pumila L.) health condition in the Left-bank Ukraine by Valentyna L. Meshkova, Olena A. Kuznetsova, Volodymyr P. Turenko

“…Among wetwood-infected trees, the bark beetle infestation significantly increased with an increase in HCI and defoliation and decreased as the diameter of the trunks decreased. Principal components analysis confirmed the highest association of bark beetle infestation with DED, epicormic shoots with wetwood disease, and dry branches with other symptomatic trees. …”
