Masters Theses
Chapter 1 is devoted to a molecular overview of the North American members of the springtail genus Orchesella using mitochondrial and nuclear DNA. Both genes strongly support the presence of four major clades within Orchesella. Chapter 2 is a morphological revision of the species near Orchesella celsa Christiansen & Bellinger. Five new species are described based largely on chaetotaxonomical differences in.
