The Effects Of Anthropogenic Noise On The Foraging Efficiency Of A Gleaning Bat And The Activity Levels Of A Natural Bat Assemblage, Jessie Patrice Bunkley
The Effects Of Anthropogenic Noise On The Foraging Efficiency Of A Gleaning Bat And The Activity Levels Of A Natural Bat Assemblage, Jessie Patrice Bunkley
Boise State University Theses and Dissertations
Anthropogenic noise is prevalent across many landscapes, posing a threat of disturbance to countless human and wildlife populations. Studies have revealed that a variety of organisms are negatively affected by an increasingly loud soundscape, including auditory predators such as bats. Bats that exhibit a gleaning hunting strategy passively listen for low frequency, prey-produced sounds. Anthropogenic noise often falls within the same spectral range as important prey cues, potentially masking these signals. I investigated the effects of two sources of anthropogenic noise, traffic and gas compressor station noise, on the foraging efficiency of the North American gleaning bat Antrozous pallidus in …
Distribution Of Chinook Salmon (Oncorhynchus Tshawytscha) In Upper-Columbia River Sub-Basins From Environmental Dna Analysis, Matthew Benjamin Laramie
Distribution Of Chinook Salmon (Oncorhynchus Tshawytscha) In Upper-Columbia River Sub-Basins From Environmental Dna Analysis, Matthew Benjamin Laramie
Boise State University Theses and Dissertations
Determining accurate species distribution is crucial to conservation and management strategies for imperiled species, but challenging for small populations that are approaching extinction or being reestablished. We evaluated the efficacy of environmental DNA (eDNA) analysis for improving detection and thus known distribution of Chinook salmon in the Methow and Okanogan Sub-basins of the Upper-Columbia River, Washington, USA. We developed an assay to target a 90 base pair sequence of Chinook DNA and used quantitative polymerase chain reaction (qPCR) to quantify the amount of Chinook eDNA in 1-L water samples collected at 48 sites in the sub-basins. We collected samples once …
Life History And Environmental Tolerance Of The Invasive Oriental Weatherfish (Misgurnus Anguillicaudatus) In Southwestern Idaho, Usa, Alexander N. Urquhart
Life History And Environmental Tolerance Of The Invasive Oriental Weatherfish (Misgurnus Anguillicaudatus) In Southwestern Idaho, Usa, Alexander N. Urquhart
Boise State University Theses and Dissertations
Invasive fish species have been identified as a major threat to aquatic biodiversity world-wide. The most successful of these invaders share several life history characteristics such as long lifespan, high fecundity, multiple reproductive events, generalized omnivorous diet, and tolerance for a wide range of environmental conditions. Although many studies have focused on well-known and economically costly invaders, there are many invasive fish about which very little is known. In this series of studies, I describe some life history characteristics of one such invasive fish, the oriental weatherfish (Misgurnus anguillicaudatus). I collected 586 specimens from water bodies connected with …
Warming Winters And Changing Habitats: Interactive Effects On Raptor Populations And Implications For Conservation, Neil A. Paprocki
Warming Winters And Changing Habitats: Interactive Effects On Raptor Populations And Implications For Conservation, Neil A. Paprocki
Boise State University Theses and Dissertations
Studies across multiple spatial and temporal scales will improve understanding of the drivers of global change including habitat degradation, invasive species, and climate change. How global drivers affect the ecology of wintering raptors in western North America and the Great Basin may have important implications for changes in distribution and abundance, and consequently population persistence. I examined the winter distributions of six western North America raptor species using Christmas Bird Count data from 1975-2011 to assess range shifts over time and in relation to temperature. Also, I considered whether population patterns within Bird Conservation Regions (BCR) were best explained by …
Genetic And Morphological Variation In Taeniatherum Caput-Medusae (Medusahead): Taxomonic Diversity, Geographic Origins, Multiple Introductions And Founder Effects, Morgan Lindsey Peters
Genetic And Morphological Variation In Taeniatherum Caput-Medusae (Medusahead): Taxomonic Diversity, Geographic Origins, Multiple Introductions And Founder Effects, Morgan Lindsey Peters
Boise State University Theses and Dissertations
Invasive species are novel to a region, thus their timely and accurate identification is a critical first step in recognizing and managing the threats that they may present in their new habitats. Accurate identification of an introduced species in its new range can prove difficult however for a species that displays taxonomic complexity in its native range, i.e. consists of multiple, morphologically similar subspecies.
Across its native range, Taeniatherum caput-medusae (medusahead) exhibits taxonomic complexity. Three subspecies have been recognized: T. caput-medusae ssp. caput-medusae, T. caput-medusae ssp.asperum, and T. caput-medusae ssp. crinitum. While subspecies …
A Multi-Gene Molecular Systematic Study Of The Kickxellomycotina, Including The Examination Of Two New Genes (Mcm7 And Tsr1) For Phylogenetic Inference, Eric Dennis Tretter
A Multi-Gene Molecular Systematic Study Of The Kickxellomycotina, Including The Examination Of Two New Genes (Mcm7 And Tsr1) For Phylogenetic Inference, Eric Dennis Tretter
Boise State University Theses and Dissertations
Kickxellomycotina is a recently described subphylum of Fungi defined by the presence of a unique disciform septal pore with a lenticular plug. The relationship between members of the group has proven difficult to resolve with traditional methods due to the degree of morphological and ecological variation among taxa within the clade. Furthermore, existing phylogenetic studies have lacked either the taxonomic coverage or had insufficient phylogenetic resolution to reveal the evolutionary history of the group.
In chapter one, I investigate the phylogenetic utility of two single-copy protein-coding genes, MCM7 and TSR1, to improve phylogenetic resolution within the clade. Suitable primers were …
