Patterns Of Genetic Structure In The American Kestrel (Falco Sparverius): Influence Of Distance And Migration And Implications For Monitoring And Management, Michaela Brinkmeyer
Patterns Of Genetic Structure In The American Kestrel (Falco Sparverius): Influence Of Distance And Migration And Implications For Monitoring And Management, Michaela Brinkmeyer
Boise State University Theses and Dissertations
Genetic structure is useful for inferring patterns of selection, gene flow and connectivity, and can define management units that aid in interpretation of spatially-specific trends and species management. American kestrels (Falco sparverius) are a widespread, generalist species with fully migratory, partial migrant, and resident populations. In many parts of their range, kestrels show evidence of declining population trends; however, it has been difficult to identify threats to kestrels because of differences in regional trends. We used a genome-wide sequencing approach to investigate the genetic structure of American kestrels, test hypotheses about the processes that influence genetic structuring of …
Mastering Mycological Mysteries With Explorations Of Harpellales Associated With Culicidae And Other Dipterans In Idaho, Michael Mccormick
Mastering Mycological Mysteries With Explorations Of Harpellales Associated With Culicidae And Other Dipterans In Idaho, Michael Mccormick
Boise State University Theses and Dissertations
Presented is the first field survey and laboratory-based study focused on Harpellales gut fungi found in Culicidae (mosquito) larvae collected from various parts of Idaho. Overall, 34 sites were sampled ranging from urban storm drains and irrigation puddles to pristine stream-side puddles. These sites yielded 17 different species of mosquitoes and three previously described species of gut fungi. Three species of mosquitoes were the first recorded observations as hosts of the following gut fungi: Culiseta alaskaensis was infested with Zancudomyces culisetae (from Renwyck Creek), Culex tarsalis with Smittium culicis (from Cottonwood Creek), and Ochleratus sp. with Smittium minutisporum (from Bear …
Quantifying Mammalian Interactions And Distributions To Inform Conservation Planning In Mozambique, Tara Easter
Quantifying Mammalian Interactions And Distributions To Inform Conservation Planning In Mozambique, Tara Easter
Boise State University Theses and Dissertations
Protected areas are a staple in conservation, but human activities outside of protected areas drive species interactions, compositions, and distributions. Research is especially needed in these multi-use landscapes to maintain habitat connectivity for entire wildlife communities between protected areas. Yet, such research is lacking in areas it is needed most, such as in sub-Saharan Africa, where human populations are expected to double by 2050. My objectives were to quantify mammal distributions, interactions, community compositions, and their relationships with human and natural factors within a sustainable-use forestry concession outside of Gorongosa National Park. I used recently developed multispecies occupancy models to …
A Human-Environment Systems Approach To Outdoor Recreation, Human Biological Stress, And Landscape Aesthetics, Ellie Dawn Opdahl
A Human-Environment Systems Approach To Outdoor Recreation, Human Biological Stress, And Landscape Aesthetics, Ellie Dawn Opdahl
Boise State University Theses and Dissertations
Outdoor recreation, as the intersection between physical exercise and nature, provides a multitude of psychological and physiological benefits to human well-being. Though many studies have reported qualitative stress reduction from outdoor recreation, few have focused on quantitative measurements of stress across recreational activity types, intrapersonal differences, and environmental variables. To determine whether outdoor recreation affects physiology, we collected 190 paired salivary cortisol and testosterone samples and 157 surveys from 88 hikers, 81 mountain bikers, and 44 off-highway vehicle (OHV) motorists. After recreation, cortisol concentrations were significantly reduced in hikers and OHV motorists, but cortisol and testosterone concentrations increased in mountain …
Building The Full Annual Cycle Picture For Long-Billed Curlews: Correlates Of Nest Success In The Breeding Grounds And Spatial Distribution And Site Fidelity In The Wintering Grounds, Stephanie E. Coates
Building The Full Annual Cycle Picture For Long-Billed Curlews: Correlates Of Nest Success In The Breeding Grounds And Spatial Distribution And Site Fidelity In The Wintering Grounds, Stephanie E. Coates
Boise State University Theses and Dissertations
Migratory birds face threats throughout the annual cycle, and cumulative effects from linkages between the breeding and non-breeding grounds may impact species at the population level. Long-billed Curlews (Numenius americanus) are a migratory shorebird of conservation concern associated with grasslands that show breeding population declines at some regional and local scales. Curlews exhibit high site fidelity to breeding territories, but also spend approximately 75% of the year on the wintering grounds. Therefore, localized population declines could indicate localized threats, in the breeding or wintering grounds. However, little information is available regarding the spatial distribution of curlews on the …
