Systematics and Glacial Population History of the Alternifolium Group of the Flowering Plant Genus Chrysosplenium (Saxifragaceae)
(University of Kansas, 2008-01-01)The flowering plant genus Chrysosplenium comprises approximately 57 species of herbaceous perennials. These species are mainly distributed in the Northern Hemisphere where they occur in moist habitats. Though the center ... -
Phylogeny, Taxonomy, Character Evolution, and Biogeography of Glassfrogs (Amphibia: Centrolenidae)
(University of Kansas, 2007-12-04)The present study provides a new hypothesis of the evolutionary relationships of Glassfrogs (Centrolenidae) inferred from mitochondrial and nuclear loci, and addresses questions on the evolution and speciation of the group. ... -
ECOLOGICAL NICHE MODELING AS A PREDICTIVE TOOL: ASIATIC FRESHWATER FISHES IN NORTH AMERICA
(University of Kansas, 2008-05-30)A major problem with invasive aquatic species is that they are almost impossible to eradicate once established. Hence, the best method to prevent establishment of such species is to assess their invasive potential proactively ... -
Arthropod and plant responses to resource availability and heterogeneity
(University of Kansas, 2008-03-26)Species diversity is one of the central topics of ecological research, and there is still uncertainty about what shapes diversity in communities. These studies explore the responses of plant and arthropod communities to ... -
PHYLOGENY AND CLASSIFICATION OF THE BEE TRIBE MEGACHILINI (HYMENOPTERA: APOIDEA, MEGACHILIDAE), WITH EMPHASIS ON THE GENUS MEGACHILE
(University of Kansas, 2008-08-15)Using a cladistic analysis of adult external morphological characters, I first explore the relationships of the tribes in the bee subfamily Megachilinae. Next, I examine the phylogeny of the subgenera of Megachile s. l., ... -
Morphology and phylogeny of the weevil subfamily Baridinae (Coleoptera: Curculionidae)
(University of Kansas, 2008-08-04)Even though the phylogenetic classification of Curculionoidea is still in its infant stages, knowledge of the morphology of the group also is relatively lacking. Significant morphological reviews have been done at the ... -
Population ecology and management of the invasive plant, Lespedeza cuneata
(University of Kansas, 2008-05-19)Lespedeza cuneata is one of the worst invasive plants across much of the North American Great Plains. In this dissertation, I describe the combination of field experimentation, statistical modeling and spatially explicit ... -
Landscape Impacts on Fish Community Structure and Food Chain Length in Prairie and Ozark Rivers
(University of Kansas, 2008-03-28)Rivers in the Ozark Highland ecoregion and Central Prairie ecoregion differ in land use and diversity, and these could impact food chain length. The primary factors controlling food chain length are not certain, but were ... -
Population genetic patterns in sister species pairs sharing a single speciation event: a study of two species pairs of freshwater fishes
(University of Kansas, 2007-10-08)This study asked whether population genetic structure of daughter species shows a pattern indicative of change caused by the speciation process. Fresh water fishes composing two geminate species pairs from a vicariant event ...
