Quantitative Song Variety In Relation To Genotype In A Hybridizing Chickadee Population, Shelby Madison Palmer
Quantitative Song Variety In Relation To Genotype In A Hybridizing Chickadee Population, Shelby Madison Palmer
MSU Graduate Theses
The Black-capped chickadee (Poecile atricapillus) and Carolina chickadee (P. carolinensis) are North American songbird species that hybridize in a narrow contact zone stretching latitudinally from New Jersey to Kansas, USA. The association between genetic ancestry and song type in this hybrid zone has been studied independently several times and found to be minimal or absent, likely due to the influence of cultural transmission on learned song in the oscine passerine clade to which the chickadees belong. Despite this, the song of both species remains remarkably distinct in allopatry, suggesting a genetic constraint on certain qualities of …
Spatial Use By Mammals Within Two State Parks In The Ozarks National Scenic Riverways, Benjamin Aaron Smith
Spatial Use By Mammals Within Two State Parks In The Ozarks National Scenic Riverways, Benjamin Aaron Smith
MSU Graduate Theses
A mammalian species inventory with comparisons between sampled sites was conducted via multiple methodologies to document presence of mammals at two Missouri state parks within the Ozark National Scenic Riverways. Camera traps, small mammal traps, acoustic detectors, and mist nets were used to detect species at the parks, and species similarity indices and occupancy analyses were used to discern use of space. A mammalian inventory was compiled for each area of inquiry. Greater diversity was found at the park with more variable habitat types. Bat activity was more in the park with a known hibernaculum, though species specific activity differed …
Fish And Macroinvertebrate Response To Restoration And Conservation Efforts, Madison C. Cogar
Fish And Macroinvertebrate Response To Restoration And Conservation Efforts, Madison C. Cogar
MSU Graduate Theses
Fish and macroinvertebrate response to restoration and conservation efforts varies in regards to the size and structure of the system (e.g. headwater streams in WV versus large rivers such as the Mississippi River). This project reviews fish and macroinvertebrate rebound in treated acid mine drainage (AMD) streams in WV as well as macroinvertebrate drift patterns in the Mississippi and Missouri Rivers. AMD is a product of a chemical reaction resulting in an acidic water outflow from mining sites, which may harm aquatic life. As a response, passive AMD treatment systems have been installed. I tested the effectiveness of remediation by …
Population Surveys And Health Assessments Of Captive And Free-Ranging Alligator Snapping Turtles, Samantha Louise Hannabass
Population Surveys And Health Assessments Of Captive And Free-Ranging Alligator Snapping Turtles, Samantha Louise Hannabass
MSU Graduate Theses
Alligator Snapping Turtles (Macrochelys temminckii) have experienced range-wide declines primarily due to overharvest for the meat market and habitat degradation in the form of damming and channelization of rivers. Head-start programs and reintroduction efforts have been initiated to release individuals throughout their historic range. Before releasing Alligator Snapping Turtles, sites need to be assessed to determine the suitability of habitat, if there is a robust turtle community already present, and the causes of the original extirpation have been eliminated. I assessed the turtle communities and documented anthropogenic impacts (e.g. boat traffic) at nine possible reintroduction sites in southeastern …
Vertical Connectivity Influences Secondary Production, Community Diversity, And Resilience In An Ozark Stream, Nathan C. Dorff
Vertical Connectivity Influences Secondary Production, Community Diversity, And Resilience In An Ozark Stream, Nathan C. Dorff
MSU Graduate Theses
The hyporheic zone, a key component of stream vertical connectivity, supports stream function (e.g., nutrient regeneration) and provides habitat for aquatic biota. The Ozark Highlands ecoregion contains gravel-bed streams that have extensive hyporheic zones and that are subject to recurrent flash floods. I sampled Leuctra tenuis(Pictet) nymphs from the hyporheic habitat (30-45 cm below the streambed) in a gravel-bed reach and an intermittent tributary of an Ozark stream from early instar to adult emergence. Concurrently, I sampled benthic insects in two reaches of the same stream that differed primarily in amount of hyporheic habitat (bedrock vs. gravel) and monitored …
Stress And Body Composition Of Juvenile Alligator Snapping Turtles (Macrochelys Temminckii), Brandon Scott Tappmeyer
Stress And Body Composition Of Juvenile Alligator Snapping Turtles (Macrochelys Temminckii), Brandon Scott Tappmeyer
MSU Graduate Theses
The alligator snapping turtle (Macrochelys temminckii), is a species of conservation concern that is the subject of multiple head-start and reintroduction efforts across its range. In captive propagation programs, producing offspring that are in optimal physiological condition maximizes the likelihood of success after release. The purpose of my study was to compare stress and body composition between one free-ranging reintroduced population and two captive populations. The two captive populations were both housed in southern Oklahoma, but one group was reared indoors whereas the other inhabited outdoor ponds at a national fish hatchery. I used circulating glucocorticoid (corticosterone) concentrations as an …
Grapevine Vein Clearing Virus: Epidemiological Patterns And Construction Of A Clone, Cory Von Keith
Grapevine Vein Clearing Virus: Epidemiological Patterns And Construction Of A Clone, Cory Von Keith
MSU Graduate Theses
Grapevine vein clearing virus (GVCV) is a recently discovered virus belonging to the Badnavirus genus. Characteristic to its name, the virus is associated with a disease where symptoms manifest as pronounced vein-clearing, resulting in severe berry deformation and vine decline in susceptible grape varieties. Sustainable production of wine is dependent on healthy plants. The associated disease is mainly found in Midwest vineyards. Attempts were made in this thesis to provide evidence of causality of the virus to the associated disease and to infer the historical path and migration pattern of GVCV. Conclusions and discussions will provide grape producers with the …
Nesting Success Of The Barn Owl (Tyto Alba) Using Nest Boxes In Southwest Missouri, Robert Grant Dickerson
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
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 …
