Systematics And Population Structure Of Amblyomma Maculatum Group Ticks And Rickettsia Parkeri, An Emerging Human Pathogen In Southern Arizona, Usa, Michelle E.J. E Allerdice

Theses and Dissertations

The recent discovery of Amblyomma maculatum sensu lato (s. l.) ticks in southern Arizona has renewed discussions around species designations for members of the Amblyomma maculatum tick group. Amblyomma maculatum s. l. from Arizona appear to be morphologically intermediate between A. maculatum sensu stricto (s. s.) and A. triste s. s. At present there is no conclusive species designation for the ticks from Arizona. My research focused on analyzing the systematics of both A. maculatum s. l. and Rickettsia parkeri, a common bacterial pathogen transmitted by these ticks.

In the laboratory, A. maculatum s. l. from Arizona and A. maculatum …

The Darkling Beetles Of The Nevada Test Site (Coleoptera - Tenebrionidae), Willis A. Packham

Theses and Dissertations

In the desert areas of southwestern United States the Coleoptera, family Tenebrionidae, constitute a conspicuous part of the ground-dwelling insects. Most species are black or dull chestnut-brown. They are primarily nocturnal and during the day can be found under rocks, debris, loose bark, or in rodent burrows. On cloudy days they may be seen lumbering along the desert floor. Most tenebrionids feed on plant materials of various sorts. In August, 1959, Brigham Young University initiated an ecological study at the Nevada Test Site near Mercury in Nye County, Nevada. As part of that study, emphasis was given to the ground-dwelling …
