A New Adaptive Landscape: Urbanization As A Strong Evolutionary Force, Lauren Christie Breza
A New Adaptive Landscape: Urbanization As A Strong Evolutionary Force, Lauren Christie Breza
Masters Theses
Urbanization is rapidly increasing as human population growth steadily grows, but there is little consensus of the ecological consequence of this population shift and almost no information of the evolutionary consequences for local biodiversity. Nearly two-thirds of the world’s population will live in city centers by 2050 with profound impacts on landscapes that can act as important agents of selection. This study aims to identify 1) the net effect of urbanization on species richness, 2) how phylogenetic diversity varies between urban and rural sites, and 3) the strength of urbanization as a selection pressure. First, a meta-analysis was conducted in …
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 …
A Systematic Review Of The Soricimorph Eulipotyphla (Soricidae: Mammalia) From The Gray Fossil Site (Hemphillian), Tennessee, Joshua Doby
Electronic Theses and Dissertations
Due in part to the incompleteness of the Cenozoic fossil record in the eastern U.S., the evolution and immigration of shrews (Soricidae) is not well understood. A rich soricid fauna from the Gray Fossil Site (GFS), Washington County, TN, has enabled many new inferences to be made. There are 7 new species in 6 genera: Paenelimnoecus, “Blarinella”, Petenyia, Tregosorex, Crusafontina, and Gen et sp. nov. GFS species of the genera Paenelimnoecus, “Blarinella”, and Petenyia are the first occurrence of each genus in the New World. Tregosorex, Crusafontina, and the N.A. taxon Limnoecus all have their latest documented occurrence at the …
