The Norwegian-Swedish Crisis of 1905 is unique because the two
kingdoms, united in a dual monarchy, separated peacably. The thesis
raises three questions: why did Norway want independence at all, why
was the secession peacable, and can any of the factors which solved
the Crisis of 1905 be injected or...
This work combines both applied and basic research regarding previously undescribed relationships between two ecologically and economically important insect groups in coniferous forests, bark beetles (Coleoptera: Curculionidae, Scolytinae) and wild bee (Hymenoptera: Apiformes) communities in Western North America. Across the continent, native bark beetle outbreaks are key drivers of structural...
