Weevils That Live Under Trees Thrown Out of the Sea: Phylogeny and Microbial Diversity of Sthereus Motschulsky, 1845 and Related Weevils (Curculionidae: Molytinae)

Creator:

Young, Natasha

Abstract:

Here the diversity and phylogeny of the genus, Sthereus Motschulsky, 1845, and its nearest associates in the large subfamily Molytinae are explored through molecular and morphological characters. Sanger sequencing of five genes determined that Sthereus is not monophyletic. Instead, the one species in the genus Gastrotaphrus Buchanan 1936, G. barberi...

Diversity and Evolution of Sexual Traits in Ground Beetles (Family Carabidae)

Creator:

Gomez, R. Antonio

Abstract:

Biologists have long been fascinated with reproductive traits, in part because they are frequently exaggerated or showy, and they commonly vary among closely related species. Exaggerated sexual traits, in particular, have been the focus of intense empirical and theoretical research, but most of this work has focused on traits involved...

Dissertation
Phylogenomics and Evolution of Ground Beetles, with an Emphasis on the Speciose Tribes Chlaeniini and Bembidiini (Coleoptera: Carabidae)

Creator:

Pflug, James M.

Abstract:

In this dissertation, I investigate the evolution and genomes of carabid beetles, a worldwide family of over 38,000 species. I focus on two species-rich groups, the tribes Chlaeniini and Bembidiini, both of which are primarily found on the shores of bodies of water. The former are distinctive for their defensive...

Delimiting Species in the Mountaintops : New Trails for Studying Genomic Architecture and Sequencing Historical Specimens Uncover Hidden Diversity within the breve Species Group of Bembidion (Coleoptera : Carabidae)

Creator:

Sproul, John S.

Abstract:

Species are one of the foundational units upon which entire fields of scientific inquiry are built. Discovering and documenting the planet’s biodiversity remains one of the grand challenges of science. A proper conceptualization of species provides a critical framework for diverse fields such as biophysics, biochemistry, agriculture and pharmacology, and...

Dissertation
Repetitive DNA profiles in Bembidion (Coleoptera : Carabidae) show variation in genomic architecture within and between closely related species

Creator:

Barton, Lindsey M.

Abstract:

The ribosomal cistron (rDNA cistron) is a tandemly repeated region in the genome that encodes for the necessary subunits to form ribosomes, complex molecules responsible for the assembly of amino acids into proteins. They are found within all cellular organisms, and evolve at relatively constant rates, making them ideal for...

Phylogenetic Studies in Tenebrionidae (Coleoptera) and Related Families

Creator:

Kanda, Kojun

Abstract:

In this dissertation, I present the results from three studies: (1) a phylogeny of Tenebrionoidea (Coleoptera) inferred from a seven-gene dataset derived from PCR and Sanger sequencing; (2) a phylogeny of Tenebrionidae, the largest family in Tenebrionoidea, inferred from a four-gene dataset also derived from PCR and Sanger sequencing; (3)...

Next-generation sequencing of Coleomyia (Diptera: Asilidae)

Creator:

Cohen, Chris M.

Abstract:

Coleomyia (Diptera: Asilidae) is a small genus of robber flies found in western North America, totaling eight described species. The goal of this project was to sequence the transcriptome and genome of Coleomyia. In the most recent phylogenetic analysis, it could not be placed in a recognized subfamily. Furthermore, there...

Vertebrates, arthropods, and invasive plants : an investigation of the top-down and bottom-up interactions of multiple herbivore guilds in a grassland system

Creator:

Farrell, Kelly Anne

Abstract:

Humans are increasing the scale and frequency of many natural disturbances, as well as adding novel disturbances to ecosystems. This thesis uses the arthropod community as a metric to examine the multi-trophic responses to disturbances in California grasslands. Chapter 2 explores how the long-term exclusion of native vertebrate herbivores has...
