A phylogeny of the species-rich clade of the Neotropical frog genus Leptodactylus sensu stricto is presented on the basis of a total evidence analysis of molecular (mitochondrial and nuclear markers) and non-molecular (adult and larval morphological and behavioral characters) sampled from > 80% of the 75 currently recognized species. Our results support the monophyly of Leptodactylus sensu stricto, with Hydrolaetare placed as its sister group. The reciprocal monophyly of Hydrolaetare and Leptodactylus sensu stricto does not require that we consider Hydrolaetare as either a subgenus or synonym of Leptodactylus sensu lato. We recognize Leptodactylus sensu stricto, Hydrolaetare, Adenomera, and Lithodytes …
The Effects Of Soil Ph On The Molting Success Of Blacklegged Ticks (Ixodes Scapularis): A Laboratory Experiment, Daniel Rice
The Effects Of Soil Ph On The Molting Success Of Blacklegged Ticks (Ixodes Scapularis): A Laboratory Experiment, Daniel Rice
Honors Theses
Ixodes scapularis, or the black-legged tick, is the major vector of Lyme disease in the U.S. I. scapularis has expanded its range in recent decades, making the study of factors affecting its distribution a high priority. Studying the effects of various conditions in the soil could help in predicting range expansions, because ticks spend the majority of their lives in contact with the soil. We investigated the effects of soil pH on the molting success of engorged I. scapularis nymphs collected from Eastern Chipmunks (Tamias striatus). The experiment was conducted in a laboratory to control for covariates such as temperature …

The Genus Palaeagapetus Ulmer (Trichoptera, Hydroptilidae, Ptilocolepinae) In North America, Tomiko Ito, Robert W. Wisseman, John C. Morse, Murray H. Colbo, John S. Weaver Iii
Publications
The genus Palaeagapetus Ulmer (Trichoptera, Hydroptilidae, Ptilocolepinae) is revised in North America. Descriptions of the western species, P. nearcticus Banks 1938, are provided with the first descriptions of the female, pupa, larva, egg and case and with notes on food, habitat and annual life cycle. The male and female of the eastern species, P. celsus Ross 1936, are described or redescribed with some ecological notes. Distributions of the two species are summarized.
