Cameron Kmetzsch and Professor Russell B Rader, Integrative Biology Rock pools are one of the most unique and threatened aquatic habitats in the world. Changes in global climate could alter precipitation patterns and disrupt the annual cycle of filling and drying to which this community has evolved. Previous misconceptions assume that all rock pools are temporary habitats. […]

Determining and Sharing Knowledge about Phylogenetic Relationships of Collomia Species (Mountain-trumpet Flowers)
Lisa Busby and Dr. Leigh Johnson, Life Science The plant genus Collomia shows great morphological and genetic diversity, however, its current classification is based on a morphological study done in 1940. This year I was able to assemble a great deal of DNA sequence information and compare the variation in these sequences with previous classifications […]
THE EFFECTS OF JUNIPER LITTER DEPTH AND ALLELOPATHY ON TWO NATIVE SPECIES
Chad S. Horman and Dr. Val Jo Anderson, Botany and Range Science Juniper (Juniperus spp.) forests cover a large percentage of the West and are continuing to invade grass/shrub ecotypes. This eventually leads to a reduced understory and lower productivity for grazing animals. This reduction in understory biomass is due to the competitiveness of this […]
Isolation and characterization of a North American species of Phasmarhabditis sp.
Nate Keplinger and Dr. Byron Adams, Biology Abstract Slugs and snails are pests that destroy various food crops throughout the entire world. To control their outbreak, Europeans have utilized the nematode Phasmarhabditis hermaphrodita, a mollusc pathogen. This nematode has not been introduced into US agriculture because it has not been found in a mollusc pathogenic […]
A FINE STRUCTURE COMPARISON OF THREE SPECIES OF ARGULUS (CRUSTACEA: BRANCHIURA) ECTOPARASITES OF FARMED AND WILD FISH
Adam Bowen and Professor Richard A. Heckmann, Zoology Argulus, commonly called fish-lice, are crustacean ectoparasites of fish. This study compared three members of the genus Argulus: A. pugetensis from Nanaimo, British Columbia; A. coregoni from Curitiba, Brazil; and A. siamensis from Bangalore, India. It was hypothesized that argulids of different taxons must have morphological variations […]
A Study of Biological Photonic Crystals in the Effects of Beta Amyloid on Nicotinic Acetylcholine Receptors in Alzheimer’s: Internal Opal Scale Structures of Iridescent Beetle Species in the Cerambycidae Family
Andrew Romney and Dr. Sterling Sudweeks, Physiology & Developmental Biology For the past two years, I have worked in Dr. Sterling Sudweeks’ research lab experimenting with neurotransmitter receptors that are implicated in the development of Alzheimer’s Disease. When functioning normally, these receptors act as ion channels which open upon binding nicotine or acetylcholine and are […]
A Study of Biological Photonic Crystals in the Internal Opal Scale Structures of Iridescent Beetle Species in the Cerambycidae Family
Lauren Richey and Dr. John Gardner, College of Life Sciences Main Text A photonic crystal is a periodic structure that confines, manipulates, and guides photons. Such structures affect the propagation of electromagnetic waves by defining allowed and forbidden frequency bands known as photonic band gaps. Therefore, a photonic crystal can be thought of as the […]
“A Rose By Any Other Name…” A Study of Flowering Plant Classification and Species Recognition
Angela Jensen and Dr. Leigh Johnson, Department of Biology Speciation is a scientific “gray area.” Conservation biologists are familiar with the many different proposed definitions for a species, encased in the 10 or so existing species concepts. Individual organisms of the same species are inherently different, possessing a wide variety of characteristics and behaviors. When […]
Screening of Secondary Chemicals from Selected Species of North American Lichens Against Various Pathologenic Bacteria
Jocelyn Raphael and Dr. Larry St. Clair, Department of Biology Lichens consist of a fungus occurring symbiotically with a photosynthetic organism (such as an alga and/or cyanobacterium). Lichens are known to produce a high number of secondary metabolites. Studies have shown that these secondary compounds have various biological roles such as antibiotic, antiviral, anti-inflammatory, anti-proliferative, […]
Development of Real-Time Polymerase Chain Reaction (q-PCR) Assays for the Detection and Identification of Drug-resistance Genes in Carbapenem-resistant Enterobacteriaceae (CRE)
Richard A. Robison, Ph.D., Microbiology and Molecular Biology I. The Specific aims for the project were as follows: Develop q-PCR assays for the various carbapenem-resistance genes, such as KPC, IMP, VIM, and NDM-1, and then multiplex them into single assays that can be used to quickly characterize an isolate. II. Accomplishments to date related to […]
