Estimation Of Probability Of Habitat Use Of Roosevelt Elk On The Olympic Peninsula, Vincent Michael Gugliotti
Estimation Of Probability Of Habitat Use Of Roosevelt Elk On The Olympic Peninsula, Vincent Michael Gugliotti
Undergraduate Theses, Professional Papers, and Capstone Artifacts
Estimating the probability of habitat use for a particular species is crucial to the direct management and conservation of that species. Without knowledge of habitat preferences, managers cannot effectively focus efforts on vital resources or landscape types. However, modelling probability of habitat use can be done in several ways which leaves room for variation and uncertainty in the estimates produced by each method. This study is an examination of the variation between two estimates of probability of habitat use while focusing on a particular subspecies of elk that inhabits a unique ecosystem relative to other elk subspecies. I modeled elk …
Determining Species-Specific False-Positive Rates Using Visual And Auditory Cues: A Case Study With Sagebrush Steppe Songbirds, Amelia K. Evavold
Determining Species-Specific False-Positive Rates Using Visual And Auditory Cues: A Case Study With Sagebrush Steppe Songbirds, Amelia K. Evavold
Undergraduate Theses, Professional Papers, and Capstone Artifacts
Errors in wildlife field data threaten to bias resulting abundance and occupancy estimates if not properly accounted for or minimized. Methods to account for false-positive errors in wildlife data have not been as thoroughly developed as those for false-negative errors despite false-positives being present across diverse wildlife taxa and study systems. The calibration method to account for false-positives involves assessing the field detection method to determine how often false-positive errors occur in the field data. Rates can then be incorporated into estimations based on the field data to improve estimation accuracy. This study presents an application of the calibration approach …
Differential Diagnosis Of Abnormal Muscle Gross Anatomy Of A Male Cadaver, Audrey V. Broffman, Carley R. Carpenter
Differential Diagnosis Of Abnormal Muscle Gross Anatomy Of A Male Cadaver, Audrey V. Broffman, Carley R. Carpenter
Undergraduate Theses, Professional Papers, and Capstone Artifacts
The ability of healthcare providers to carefully consider all presentations of illness and injury, draw upon research and knowledge to develop a list of potential diagnoses, and further investigate systems expected to be impacted by these diagnoses, is crucial for accurate identification of a condition and subsequent treatment plans to improve the welfare of patients. In order to determine a possible cause for unusual anatomic changes in multiple regions of the male cadaver used in the University of Montana’s Anatomy and Physiology lab, we performed a differential diagnosis.This research is exempt from IRB approval because the individual is no longer …
Characterizing The Requirements For The Matricellular Protein, Dccn, In Nervous System Function, Elizabeth L. Catudio Garrett
Characterizing The Requirements For The Matricellular Protein, Dccn, In Nervous System Function, Elizabeth L. Catudio Garrett
Graduate Student Theses, Dissertations, & Professional Papers
The brain is organized as a complex network of specialized neurons that communicate via a combination of electrical and chemical signals. Our brains function to generate movement, control organ function, or direct complex behaviors; all of which requires the ability to regulate the flow of communication between circuits and networks. Work in this thesis addresses two areas of neuron communication: first, how does the release of more than one neurotransmitter from a single neuron impact behavior, and second, are matricellular proteins (MCPs) key contributors to synaptic transmission and neuron function? The conserved CCN family of MCPs have a …

Methods For Estimating Mountain Goat Occupancy And Abundance, Molly Mcdevitt
Graduate Student Theses, Dissertations, & Professional Papers
Abundance and occupancy are two parameters of central interest to the field of ecology. Furthermore, accurate (both precise and unbiased) estimates are key pieces to the puzzle of effective wildlife management decision-making. While there exist a variety of sampling techniques and statistical models for effectively estimating population parameters for frequently encountered and large mammals, methods for sampling unmarked and rare species are few and far between. The first step to acquiring usable parameter estimates is through the use of sampling theory and incorporation of probabilistic sampling designs to collect count-data and occurrence-data. Often, it is assumed that probabilistic sampling designs …
