Ticks On Lizards: Parasite-Host Interactions Of The Southern Alligator Lizard (Elgaria Multicarinata) In Washington State, Emma Houghton
Ticks On Lizards: Parasite-Host Interactions Of The Southern Alligator Lizard (Elgaria Multicarinata) In Washington State, Emma Houghton
All Undergraduate Projects
I investigated interactions between ectoparasites (ticks) and their host, the southern alligator lizard (Elgaria multicarinata). Alligator lizards are capable of complement-mediated killing of the Lyme disease spirochete carried by ticks and may potentially reduce Lyme disease prevalence by cleansing pathogenic organisms from ticks. Despite this, little is known about host-parasite dynamics in alligator lizards. My goals were to 1) assess patterns of tick presence (i.e. parasite load) on alligator lizards and 2) investigate potential negative effects of ticks on alligator lizards. I sampled lizards during the summer of 2019 near Catherine Creek, along the Columbia River Gorge in southern Washington. …
Acoustic Analysis Of Nomascus Gibbon Songs As A Potential Measure Of Current Health Status, Caroline Rowley
Acoustic Analysis Of Nomascus Gibbon Songs As A Potential Measure Of Current Health Status, Caroline Rowley
All Master's Theses
Post-release monitoring is vital to the rehabilitation process. Gibbons offer a unique challenge, as they are notoriously difficult to follow through the forest, but their duets offer a non-invasive window into their lives. The aim of this project is to create a method that will evaluate the health of rehabilitated and released gibbons through acoustic analyses. Gibbon duets are in part genetically determined, but learning may play a role in song development. Additionally, songs may indicate resource holding potential, and are vital to acquiring mates and producing offspring. Captive-raised gibbons are often denied the experience of co-singing with their parents, …
Mommy Issues: Do Differential Rearing Histories Affect The Social Behavior Of Captive Chacma Baboons (Papio Ursinus), Madeleine Spencer
Mommy Issues: Do Differential Rearing Histories Affect The Social Behavior Of Captive Chacma Baboons (Papio Ursinus), Madeleine Spencer
All Master's Theses
I observed the behavior of 17 chacma baboons (Papio ursinus) in order to understand the relationship between rearing history, dominance hierarchy, and social behavior. The Centre for Animal Rehabilitation and Education (C.A.R.E.) has utilized hand-rearing in the past and is currently using a surrogate-rearing method. Hand-rearing involves one or more primary caregivers attending to an infant for 6 – 12 months. Surrogate-rearing involves one individual being the primary surrogate for the first 3 months of the infant’s life prior to bonding her or him to an adult female baboon before integrating both back into the surrogate’s troop. Mother-reared …
Early Life History And Stock Discrimination Of Kokanee Salmon (Oncorhynchus Nerka) In An Alpine Lake Environment, Alexandra Mccarrel
Early Life History And Stock Discrimination Of Kokanee Salmon (Oncorhynchus Nerka) In An Alpine Lake Environment, Alexandra Mccarrel
All Master's Theses
This study examines an ecologically and recreationally important population of kokanee salmon (Oncorhynchus nerka) residing in Keechelus Lake and its tributary Gold Creek in the central Cascades of Washington State. This population of kokanee salmon is a vital food base for a population of ESA-listed resident bull trout. However, little is known about the early life history of this population and how it interacts with unique features in its rearing environment. With my research I described the early life history of kokanee salmon that spawn in the lake’s main tributary, Gold Creek, and proposed a framework to determine …

Investigating The Avian Species Composition, Diversity, And Abundance Of Engelhorn Pond, Kiana Rose
Investigating The Avian Species Composition, Diversity, And Abundance Of Engelhorn Pond, Kiana Rose
Undergraduate Honors Theses
Central Washington University’s Engelhorn Pond contains important habitats for many organisms, particularly migratory birds, and is a valuable resource for students. However, little information is available about the wildlife inhabiting the pond. The pond’s discrete location means that many people are unaware of its existence. In addition, the pond is threatened by a number of anthropogenic sources, including chemical runoff, garbage, and feral cats. By using point counts, a common ornithological survey technique, I recorded the bird species present at the pond during all seasons of the year. I collected data using point counts during 13 visits from June of …
Sampling The Local Fare: Fishes At The Sam Israel House Pit (45gr76), Soap Lake, Washington, Adam Fruge
Sampling The Local Fare: Fishes At The Sam Israel House Pit (45gr76), Soap Lake, Washington, Adam Fruge
All Master's Theses
The Sam Israel site is a precontact archaeological complex with numerous fish bones at the north end of Soap Lake, Washington. Excavated in 1976, the fish remains recovered from there were never fully analyzed prior to this research. Since this inland Columbia Plateau site had thousands of fish bones, it contained untapped potential for our understanding of ancient local fish procurement. As such, I conducted a detailed analysis of 2,862 fish bone specimens from the Sam Israel House Pit locus to: study a larger sample of fish bones in greater detail than was done before; compare the distribution of fishes …
Group Differences In Mother-Infant Macaca Fascicularis Behavior, Parasite Load, And Body Condition Within An Anthropogenically Altered Forest, Elizabeth M.C. Coggeshall
Group Differences In Mother-Infant Macaca Fascicularis Behavior, Parasite Load, And Body Condition Within An Anthropogenically Altered Forest, Elizabeth M.C. Coggeshall
All Master's Theses
This study aimed to establish preliminary health and behavioral data, as well as understand group variation for a large population of Macaca fascicularis individuals within an anthropogenically altered monkey forest. A parasitic analysis of 40 mother and infant individuals showed that M. fascicularis carried 13 different parasitic taxa, and that there was parasitic variation between groups. Body condition scores were determined using a newly created and adapted body condition scale from 146 sampled mother macaques. Body condition scores were significantly different between groups, specifically the pond group when compared to the three other groups. Mother-infant behavioral differences were seen between …
