An Ecological Comparison Between Resource Subsidies: Pacific Lamprey (Entosphenus Tridentatus) And Pacific Salmon (Oncorhynchus Spp.), Jocelyn Wensloff
An Ecological Comparison Between Resource Subsidies: Pacific Lamprey (Entosphenus Tridentatus) And Pacific Salmon (Oncorhynchus Spp.), Jocelyn Wensloff
All Master's Theses
Historically, oligotrophic Pacific Northwest (PNW) streams received annual returns of spawning anadromous fish that provided resource subsidies in the form of marine-derived nutrients (MDN), thus driving stream food web productivity. To date, many studies in the PNW have focused on Pacific salmon (Oncorhynchus spp.) as a resource subsidy, overlooking other anadromous fish species such as Pacific lamprey (Entosphenus tridentatus). Both Pacific salmon and Pacific lamprey are culturally important to PNW tribes for ceremonial, medicinal, and subsistence purposes, and have been since time immemorial. Unfortunately, both salmon and lamprey populations are in decline. Historically, lamprey have been disregarded …
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 …
Evaluation Of The Relationship Between Land Use And Water Quality In Kittitas County, Wa, Lindsay Schulz
Evaluation Of The Relationship Between Land Use And Water Quality In Kittitas County, Wa, Lindsay Schulz
All Master's Theses
Water in Kittitas County is extremely valuable since it supports farming, recreation, and cultural activities, as well as environmental processes and a diversity of biological life while providing many ecosystem services. However, land conversions required by agricultural and urban land uses can negatively impact water quality and the biological function of the stream. I studied how forested, agricultural, and urban land use affect six streams. Fourteen sites were sampled, once each in July, August, and September 2019. Land use was calculated as a percentage of forested, agricultural, and urban land use within a 100-m buffer of the stream, upstream of …
A Novel Snp Genotyping Technique To Determine Orangutan Relatedness And Genetic Diversity At Camp Leakey In Tanjung Puting, Central Kalimantan, Ruth Ella Linsky
A Novel Snp Genotyping Technique To Determine Orangutan Relatedness And Genetic Diversity At Camp Leakey In Tanjung Puting, Central Kalimantan, Ruth Ella Linsky
All Master's Theses
Genetic studies of dispersal patterns in wild populations of orangutans (Pongo spp.) have sought to confirm behavioral observations that female orangutans tend to stay near their natal range while males disperse. In order to genotype a previously unsampled wild population of endangered orangutans at Tanjung Puting National Park I developed novel application of a methyl based magnetic capture for enrichment of fecal DNA and commercial human targeted single nucleotide polymorphism (SNP) microarray technology. I confirmed results of this new genotyping technique through standard microsatellite short tandem repeat (STR) micro-capillary genotyping. I estimate genetic diversity and relatedness (r) …
Modeling Sex-Specific Seasonal Habitat Selection For Elk (Cervus Elaphus) In Central Washington, Lewis Meyers
Modeling Sex-Specific Seasonal Habitat Selection For Elk (Cervus Elaphus) In Central Washington, Lewis Meyers
All Master's Theses
Elk (Cervus elaphus) are generalist herbivores, exploiting a variety of environments. I studied habitat selection and sexual segregation of the Colockum elk herd in central Washington. I used a resource selection probability function (RSPF) to evaluate habitat use by males and females during summer and winter seasons. I assisted Washington State Department of Fish and Wildlife (WDFW) in capturing and placing GPS collars on males, and used an existing GPS dataset from females to investigate the extent to which sexual segregation was occurring in the Colockum herd. During summer, males selected steep slopes on north, west and south …
Resolving Gnetum Evolutionary History, Angela Mcfadden
Resolving Gnetum Evolutionary History, Angela Mcfadden
All Master's Theses
Gnetum are non-flowering seed plants of the tropics, indigenous to South America, Africa, and Asia. This group of about 40 species is fascinating to botanists because it shares distinctive morphological characteristics with flowering plants, such as broad leaves, woody stems, and flower-like strobili. There are still questions surrounding the relationships within the genus of Gnetum. With that in mind, I focused my work on generating phylogenetic hypotheses, using two molecular data sets: a concatenation of over 60 different chloroplast genes (66,815 base pairs), and the whole chloroplast genome (128,772 base pairs). This allowed me to compare the two phylogenies …
Provisioning And Its Effects On The Social Interactions Of Tibetan Macaques (Macaca Thibetana) At Mt. Huangshan, China, Brianna I. Schnepel
Provisioning And Its Effects On The Social Interactions Of Tibetan Macaques (Macaca Thibetana) At Mt. Huangshan, China, Brianna I. Schnepel
All Master's Theses
The dispersal patterns of food resources has a significant effect on the composition of primate groups and social interactions within those groups. Humans often alter the dispersal of food. Non-humans often use affiliative behaviors to elicit tolerance or support from other group members. I investigated whether provisioned food resources alter the social interactions and group dynamics of Macaca thibetana. All-occurrence sampling and scan sampling were used for data recorded by camera traps. Trail-cameras were placed at six locations that contain natural and human food resources and recorded 60-second videos. Social behavior and proximity of the monkeys were recorded. I …
Evaluating The Utility Of Beaver Reintroduction Programs For Enhancing Habitat For Rainbow Trout And Steelhead, Jonathan Rodger Hegna
Evaluating The Utility Of Beaver Reintroduction Programs For Enhancing Habitat For Rainbow Trout And Steelhead, Jonathan Rodger Hegna
All Master's Theses
Beaver reintroduction programs are increasingly being viewed as a way to enhance salmonid habitat and production. However, the actual effectiveness of using beavers as a habitat enhancement tool for ESA listed steelhead Oncorhynchus mykiss populations is unknown. We examined the type of habitat, at both the microhabitat and mesohabitat levels, preferred by steelhead in three small streams in the upper Yakima Basin, WA through standard snorkel surveys and habitat measurements. Our results suggest that steelhead in small streams strongly prefer (relative to availability) microhabitats that have deeper water(> 30 cm), slow stream velocities(< 0 .05 mis), and complex cover types. Habitat partitioning among the size-classes (small< 50 mm, medium 50-90 mm, large> 90 mm total length, TL) principally operated …
