Tree Canopy Cover Influences Habitat Use Of Breeding Birds At Jack Mountain Wildlife Management Area, Kaleigh Thomas
Tree Canopy Cover Influences Habitat Use Of Breeding Birds At Jack Mountain Wildlife Management Area, Kaleigh Thomas
Honors Theses
Across the United States, bird populations have declined due to habitat loss. To better understand habitat use by birds, researchers observed populations at Jack Mountain Wildlife Management Area in southwest Arkansas. Students at Ouachita Baptist University surveyed 94 point count locations to estimate species diversity (total number of species observed) and species abundance (total number of individuals observed). At each point, students recorded the percentage of tree canopy cover, ground cover, midstory cover, and shrub cover. These variables were used as explanatory variables in multiple regression analyses to determine which variables were influential in explaining variation in species diversity and …
Bird Diversity And Abundance In Relation To Habitat Complexity At Jack Mountain Wildlife Management Area, Grace Tidwell
Bird Diversity And Abundance In Relation To Habitat Complexity At Jack Mountain Wildlife Management Area, Grace Tidwell
Honors Theses
Since 1973, North America has lost 2.9 billion birds due to habitat loss and fragmentation. To assess the effects of habitat complexity on bird diversity and abundance, 96 locations were surveyed at Jack Mountain Wildlife Management Area (WMA) using ten-minute point counts. All birds seen and heard at each point were documented, and habitat complexity was assessed by examining the percentage of ground coverage, shrub coverage, midstory tree layer, and canopy coverage at each point. A habitat complexity index was generated from these plant surveys. Previous research at Jack Mountain has shown that habitats dominated by pine trees had the …
Effects Of Prescribed Fire On Soil Respiration In A Longleaf Pine Forest., Caroline E. Paxton
Effects Of Prescribed Fire On Soil Respiration In A Longleaf Pine Forest., Caroline E. Paxton
Honors Theses
Prescribed fire is a common tool used to increase the herbaceous diversity in longleaf pine forest understories and to eliminate competition from undesirable mid-canopy species. Little is known about the effects of these fires on the soil respiration rates within these forests. A study of the effects of prescribed fire on soil respiration was conducted within a longleaf pine stand at the Lake Thoreau Environmental Center to examine soil respiration across seasons and before and after a prescribed fire. Soil CO2 efflux rates were measured using a LICOR LI-8100A gas flux system with long-term chambers from October 2020 to …
A Baseline Documentation Report For The Delta Wind Birds Sky Lake Nature Reserve, Preston T. Perkins, J Hays Dubberly, Michael J. Thomas
A Baseline Documentation Report For The Delta Wind Birds Sky Lake Nature Reserve, Preston T. Perkins, J Hays Dubberly, Michael J. Thomas
Honors Theses
The purpose of this baseline documentation is to conduct a report on our subject property and discuss the findings. A conservation easement is established by upholding a certain standard of a property’s current condition which makes a baseline documentation necessary for an easement to be enacted. Baseline documentation reports are used as a resource to monitor and enforce the legal agreements of the conservation easement. The subject property is currently owned by the Delta Wind Birds organization. In our scenario, this documentation report will serve to aid in the conversion of our subject property into a conservation easement in which …
Population Genetics Of A Recent Range Expansion By The Southern Pine Beetle, Dendroctonus Frontalis, Into The Northeastern United States, Megan Stubbs
Honors Theses
Population genetics as a field of study aims to determine the genetic variation among individuals in a population, and differences among populations. Certain population genetic analyses can provide such information and be used to better understand the biological aspects to a species’ expansion beyond its native range. The southern pine beetle (SPB), Dendroctonus frontalis, has become an invasive pest to pine forests in northeastern United States with its recent range expansion. Nine microsatellite loci were first developed and then used in analyses. To determine what the genetic variation is among individuals in SPB populations across its entire range, including …
Interactions Of Fire And Herbivory On The Management Of Ilex Glabra In Longleaf Pine Forests, Courtney R. Filliben
Interactions Of Fire And Herbivory On The Management Of Ilex Glabra In Longleaf Pine Forests, Courtney R. Filliben
Honors Theses
The longleaf pine forest is characterized by the high levels of biodiversity and species richness that give it both ecological and economical importance. Decades of clear-cutting, habitat fragmentation, and natural fire restriction have reduced this once great forest system to a mere fraction of its original range. One of the specific causes of the decline of the longleaf pine is understory domination by woody shrubs. These shrubs limit the growth of characteristic grasses and forbs that are responsible for the majority of the biodiversity. The overall purpose of this study was to identify a new longleaf pine reforestation technique that …
Family Ties: Mainstream Environmentalists' Understanding Of Radical Environmentalism In America, Zachary W. Ezor
Family Ties: Mainstream Environmentalists' Understanding Of Radical Environmentalism In America, Zachary W. Ezor
Honors Theses
Environmentalism in the United States manifests itself in numerous ways. While American environmentalists have been grouped into broad camps over the years, observers have struggled to accurately classify the different components of the movement. Lately, environmentalists have been characterized based on their chosen modus operandi. Environmentalists who employ typical interest group tactics of policy advocacy and accept the notion of political compromise can generally be called 'mainstream.' Alternatively, those environmentalists who employ non-conventional strategies like direct action and take a no-compromise stance on environmental issues are typically described as 'radical.' Despite these distinctions, both radical and mainstream environmentalists are parts …
The Effects Of Fire And Deer Herbivory On Oak Regeneration In An Eastern Deciduous Forest, Julie La Spina
The Effects Of Fire And Deer Herbivory On Oak Regeneration In An Eastern Deciduous Forest, Julie La Spina
Honors Theses
In the past, oak was one of the most dominant species groups in the deciduous forests of the northeastern United States. More recently, a variety of factors, including interspecific competition, fire suppression and deer herbivory, have led to the decline of oaks. We studied how oaks regenerate and grow following a major disturbance, and how their growth interacts with deer herbivory. We measured the growth of seedlings of three tree species following the 1,200 hectare Overlook Fire that occurred in Minnewaska State Park, NY in April 2008. At each of three sites, we measured the growth of twenty Quercus prinus, …
