Master's Theses
Leptodactylus validus exhibits an unusual distribution inhabiting Trinidad, Tobago, and the Lesser Antilles, but not the mainland of South America. This distribution is inconsistent with other distribution patterns observed for these islands. Although slight variation in adult morphology has been observed among the island populations, call data suggest the presence of a single species. Calls of Leptodactylus pallidirostris from Venezuela suggested that this taxon might be conspecific with L. validus. Herein sequence data from the 12S and 16S mt rRNA genes were collected and analyzed in order to address: 1.) whether more than one species is represented within L. validus, …

Honors Theses
Water and plasma are forced from the capillaries into the interstitial fluid. This fluid is useful l as it moves materials between cells. Most of this fluid is collected in the capillarie of a second circulatory system, the lymphatic system. The first function of such a system is returning the excess blood plasma, now o as lymph, that has accumulated in the tissue spaces. Lymph flows from small lymph capillaries into lymph vessels that are similar to veins in having valves that prevent back flow. Lymph vessels collect to lymph nodes, lymph organs, or to the cardiovascular system at the …
