Plant Toxins Influence Diet Selection And Intestinal Parasites In A Specialist Herbivore, Marcella Rene Fremgen
Plant Toxins Influence Diet Selection And Intestinal Parasites In A Specialist Herbivore, Marcella Rene Fremgen
Boise State University Theses and Dissertations
Herbivores select plants and patches that generally maximize nutrient intake and minimize intake of plant secondary metabolites (PSMs). Protein is important for growth, reproduction and maintenance, but maximizing intake of protein is often limited by concentrations of PSMs that are potentially toxic to herbivores and energetically expensive to process. However, the consequences of ingesting PSM are often dose-dependent. At high doses, PSMs generally have negative physiological effects and are avoided, but some PSMs can be therapeutic against parasites at low doses and could therefore be selected. We used Greater Sage-grouse (Centrocercus urophasianus, hereafter, sage-grouse) to test how PSMs influence …

Speciation In Western North America: Lomatium As An Example Of Diversification And Convergent Evolution, Edgar M. Sosa, Lauren Polito, Mckayla Stevens, Donald H. Mansfield, James F. Smith (Mentor)
Idaho Conference on Undergraduate Research
Species delimitations and understanding the processes that drive speciation are essential to nearly all aspects of human endeavor. Determining species boundaries traditionally used morphology. Phylogenetic analyses based on DNA sequence data provide a means to resolve species boundaries, as well as test hypotheses regarding the evolutionary processes. Numerous species radiations have occurred in Western North America. Among these are several plant groups such as Astragalus, Artemisia, and Lomatium. Recent phylogenetic analyses of Lomatium and related genera have demonstrated that many of the morphological characters used to delimit taxa have arisen multiple times and that most taxa are para- …
Resolving Relationships At The Animal-Fungal Divergence: A Molecular Phylogenetic Approach For Understanding The Ecology And Evolution Of The Protist Trichomycetes, Nicole K. Reynolds
Resolving Relationships At The Animal-Fungal Divergence: A Molecular Phylogenetic Approach For Understanding The Ecology And Evolution Of The Protist Trichomycetes, Nicole K. Reynolds
Boise State University Theses and Dissertations
The Ichthyosporea (= Mesomycetozoea) is a relatively understudied class of unicellular symbionts that molecular phylogenies have placed at the divergence of animals and fungi. Subsumed in this class are the cosmopolitan families Eccrinidae and Amoebidiidae (referred to as “protist trichos” or “trichos” herein), which are considered obligate commensal endobionts of various arthropods, including marine, freshwater and terrestrial hosts. Once thought to be members of the fungal class Trichomycetes due to their hyphal-like growth form and ecological similarity, molecular evidence has necessitated reclassification. However, evolutionary relationships within and between them are still unclear as the number of taxa sampled and/or the …
