Habitat Associations And Fine-Scale Movements Of The Red-Spotted Toad (Anaxyrus Punctatus) In Kansas And The Efficacy Of Remote Telemetry For Monitoring Small-Scale Movements, Elisabeth Russell
Master's Theses
As climate change progresses, arid-adapted anurans might be particularly susceptible to population declines because of their reliance on ephemeral pools for successful reproduction. Because arid-adapted anurans are difficult to study due to short active seasons and cryptic lifestyles, little is known about their habitat preferences. One such arid-adapted species is the Red-Spotted Toad (Anaxyrus punctatus; RST), a Kansas Species in Need of Conservation. Since this designation in 1987, little research has been conducted to understand their conservation needs. During the summers of 2021 and 2022, RST surveys were conducted both near areas where the species has historically been …
Efficacy Of Non-Lethal Molecular Methods In Elucidating Distribution Of Gray Treefrog Complex (Hyla Chrysoscelis/Versicolor) In Kansas, Nora K. Lazerus
Efficacy Of Non-Lethal Molecular Methods In Elucidating Distribution Of Gray Treefrog Complex (Hyla Chrysoscelis/Versicolor) In Kansas, Nora K. Lazerus
Master's Theses
Globally, amphibians are the most imperiled vertebrate taxa in part because they rely on both aquatic and terrestrial ecosystems. Specifically, their permeable skin makes them uniquely susceptible to habitat degradation and alteration. Cope’s Gray Treefrog (Hyla chrysoscelis) and the Gray Treefrog (Hyla versicolor) are a diploid-tetraploid, morphologically indistinguishable sister pair of cryptic anurans native to Kansas. Since 1987, the distribution of gray treefrogs in Kanas has extended west but the status of each species in the complex in Kansas is not known beyond its documented combined western expansion. Currently, species identification cannot be determined by nonlethal …
Evaluation Of Methods For The Restoration Of Native Grasslands On Abandoned Center Pivots In The Sandsage Prairies Of Southwestern Kansas, Alonso Barragan-Martinez
Evaluation Of Methods For The Restoration Of Native Grasslands On Abandoned Center Pivots In The Sandsage Prairies Of Southwestern Kansas, Alonso Barragan-Martinez
Master's Theses
Throughout southwestern Kansas thousands of acres of native grassland have been converted to cropland for agricultural use, reducing native prairie by over 60% in the sandsage prairie. Due to low precipitation and arid conditions, much of these croplands are irrigated by center pivot irrigation systems fed by the Ogallala Aquifer. These fields are abandoned when the aquifers dry up, resulting in erosion of the unused farmland. Conservation programs such as the Conservation Reserve Enhancement Program (CREP) were established to address this problem but have been unsuccessful in restoring native grasslands in abandoned croplands in southwestern Kansas. We hypothesized that insect …
The Effect Of Vegetative Structure On Nest-Burrow Selection By The Western Burrowing Owl: Comparing Traditional Methods To Photogrammetry With An Unmanned Aerial System, Dylan J. Steffen
Master's Theses
The shortgrass prairie ecoregion in the United States has been reduced to 52% of its historical extent, contributing to reduced habitat for native species. One such species is the Burrowing Owl (Athene cunicularia). The Western Burrowing Owl subspecies (A. c. hypugaea) is listed as a Species of Special Concern in nearly every western and midwestern state, including Kansas where it is designated as a Tier II Species of Greatest Conservation Need. Habitat destruction due to conversion to cropland, increasing use of pesticides, and reduction in burrowing mammal abundance are the primary threats that have led to …
Incorporating Multi-Spectral Imaging Into Long-Term Upland Breeding Bird Monitoring, Kyle William Schumacher
Incorporating Multi-Spectral Imaging Into Long-Term Upland Breeding Bird Monitoring, Kyle William Schumacher
Master's Theses
Quivira National Wildlife Refuge in Kansas, United States partnered with Fort Hays State University Hays, KS in 2014 to begin a collaborative research project that aimed to develop a long-term monitoring protocol guided by the Comprehensive Conservation Plan for the refuge published in 2013. This plan identified specific wildlife taxa underrepresented in management impact assessments throughout the property. As a result of this plan, surveys were established to monitor interactions between upland breeding birds and the vegetation community. I conducted point count surveys in 2016, 2017, and 2018 for 122 observation points across four transects. I measured seventeen vegetation variables …
