The Spatial Ecology And Microhabitat Selection Of The Pygmy Rattlesnake (Sistrurus Miliarius) In Southwestern Missouri, Dylan Wallace Maag Dec 2017

The Spatial Ecology And Microhabitat Selection Of The Pygmy Rattlesnake (Sistrurus Miliarius) In Southwestern Missouri, Dylan Wallace Maag

MSU Graduate Theses

Despite a wide distribution throughout the southeastern United States, pygmy rattlesnakes (Sistrurus miliarius) have received less research attention than many other rattlesnake species. I captured a total of 33 S. miliarius at the Drury-Mincy Conservation Area (DMCA) and retained 14 large individuals (mostly gravid females) for a radio telemetry study. Snakes were primarily captured during evening road driving surveys and were encountered rarely with any other sampling technique. Sistrurus miliarius are widespread at DMCA where they were encountered in forest, savanna, and glade habitats. Snakes selected microhabitats with more vegetative cover and tree canopy closure than random sites …


The Effect Of Weight Carried And Time Ridden On Back Pain In Horses Ridden During Horse Shows As Determined By Pressure Algometry, Meghan Louise Mothershead Dec 2017

The Effect Of Weight Carried And Time Ridden On Back Pain In Horses Ridden During Horse Shows As Determined By Pressure Algometry, Meghan Louise Mothershead

MSU Graduate Theses

The objective of this study was to determine the effects of weight carried (rider + tack) on back pain in horses used in riding classes and a series of intercollegiate horse shows. Sixteen school horses (431-649 kg) were ridden consistently over a semester. Cross sectional images were used to measure width and put in a mapping program to figure total area. Back pain scores were determined using a pressure algometer on predetermined points over the horses back. Pain scores were recorded over five periods, including 28 d into the semester (P1) and during the show period on three consecutive Fridays …


Nesting Success Of The Barn Owl (Tyto Alba) Using Nest Boxes In Southwest Missouri, Robert Grant Dickerson Aug 2017

Nesting Success Of The Barn Owl (Tyto Alba) Using Nest Boxes In Southwest Missouri, Robert Grant Dickerson

MSU Graduate Theses

The Barn Owl (Tyto alba) is a medium-sized owl belonging to the family Tytonidae. They raise young within natural cavities and on hard surfaces including nest boxes. The nesting success of Barn Owls, using wooden nest boxes, was studied in southwestern Missouri in 2016. Data were collected on clutch and brood sizes, the numbers of young fledged, and the species and amount of prey found in their regurgitated pellets. Interaction between Barn Owls and Great Horned Owls (Bubo virginianus) was also observed and documented. Nest box occupancy was 30% which is lower than in other studies, however this study included …


Habitat Associations With Small Mammal Communities At Wilson's Creek National Battlefield, Stephanie Anne Ellison Aug 2017

Habitat Associations With Small Mammal Communities At Wilson's Creek National Battlefield, Stephanie Anne Ellison

MSU Graduate Theses

The purpose of this study was to aid the National Park Service at Wilson’s Creek National Battlefield with the reported habitat monitoring and management goals through vegetation and wildlife surveys within the park. I provided a description of two major habitat types that are of ecological concern, which included non-native ruderal grasslands and upland deciduous woodlands and forests. I evaluated small mammal communities to determine factors that may affect the detection of individual species and examined habitat associations with occupancy, as small mammals are good indicators of habitat quality. My study highlights the need to manage invasive species such as …
