Study Of Morphological And Physiological Properties And Pollinators Of The Invasive Callery Pear, Prabina Sharma
Study Of Morphological And Physiological Properties And Pollinators Of The Invasive Callery Pear, Prabina Sharma
All Theses
Callery pear is an invasive tree in 15 states of United States and is currently present in 37 states. Its management has challenged landowners and land managers. Despite being listed as a noxious weed in four states, its study is limited. The accurate estimation of Callery pear biomass will give a clearer picture of the level of invasion and help land managers develop different strategies to control its population. Similarly, identifying possible pollinators of Callery pear is essential to have some insights on pollinators associated with this tree. Hence, the objectives of this study are 1) to calculate total above-ground …
Immediate Response Of Bats To Prescribed Fire And Impact Of Experiences On Women's Self-Image In Natural Resources Professions, Zebria Hicks
Immediate Response Of Bats To Prescribed Fire And Impact Of Experiences On Women's Self-Image In Natural Resources Professions, Zebria Hicks
All Theses
To inform use of prescribed fire management practice in the southeastern US, we studied its impact on bats, which are important and at-risk species. We evaluated if prescribed fire had a positive, neutral, or negative effect on bat activity in the two weeks following the burns. We recorded bat activity after prescribed burns in February and March 2022 in northwestern South Carolina in select hardwood and pine stands and control sites ≥ 500 m from burn boundaries. We measured insect abundance, canopy cover, basal area, and understory density at each site. We recorded 687 passes during our 45-day study period. …
Use Of Macroinvertebrates In Bioassessment Of Land Use And Water Quality In Northern Mongolia, Oyunchuluun Yadamsuren
Use Of Macroinvertebrates In Bioassessment Of Land Use And Water Quality In Northern Mongolia, Oyunchuluun Yadamsuren
All Dissertations
Land-use practices in Mongolia lead to habitat degradation and consequently affect the structure and function of biological communities. There is no accepted bioassessment technique for determining the ecological consequences of habitat degradation on biological communities and water quality in Mongolia, such that a monitoring and management program suitable for Mongolia is sorely needed. Both a trait-based approach and the North American Rapid Bioassessment Protocol (RBP) metrics were tested with macroinvertebrates to determine the performance and applicability of these approaches for predicting general ecological responses of freshwater and terrestrial communities to habitat variation due to overgrazing and mining in northern Mongolian …
Factors Influencing The Distribution And Structure Of Tropical Vascular Epiphyte Communities At Multiple Scales, Carrie Woods
Factors Influencing The Distribution And Structure Of Tropical Vascular Epiphyte Communities At Multiple Scales, Carrie Woods
All Dissertations
Understanding the factors that determine species distributions is a central question in ecology. Niche-based theories stress the importance of environmental heterogeneity in influencing species distributions while neutral-based theories emphasize the effects of dispersal limitation. The relative importance of these factors in influencing species distributions may depend on spatial scale - deterministic factors may be more important at small spatial scales where fine-scale habitat factors become more relevant and stochastic factors may be more important at larger spatial scales where dispersal limitation becomes more relevant. I examined the influence of deterministic and stochastic factors on the distribution and structure of vascular …
Species Diversity And Seasonal Abundance Of Scarabaeoidea At Four Locations In South Carolina, Kevin Hinson
Species Diversity And Seasonal Abundance Of Scarabaeoidea At Four Locations In South Carolina, Kevin Hinson
All Theses
ABSTRACT
Using light, flight-intercept, and pitfall traps, 74, 327 specimens of Scarabaeoidea were captured at four golf courses in South Carolina during 2009-2010. Aphodiinae were identified only to the subfamily level and totaled 57,502 specimens. 16,825 specimens in 47 genera and 104 species in the families Ceratocanthidae, Geotrupidae, Hybosoridae, Lucanidae, Passalidae, Scarabaeidae (excluding Aphodiinae), and Trogidae were identified based on morphological characteristics. Similar to other southeastern studies focusing on phytophagous scarabs, the most abundant species consisted of Dyscinetus morator (Fabricius), Euetheola humilis (Burmeister), Cyclocephala lurida Bland, and Hybosorus illigeri Reiche. The most speciose genus captured was Phyllophaga Harris, totaling 22 …
Responses Of Upland Herpetofauna To The Restoration Of Carolina Bays And Thinning Of Forested Bay Margins, Joseph Ledvina
Responses Of Upland Herpetofauna To The Restoration Of Carolina Bays And Thinning Of Forested Bay Margins, Joseph Ledvina
All Theses
Research on the effects of wetland restoration on reptiles and amphibians is becoming more common, but almost all of these studies have observed the colonization of recently disturbed habitats that were completely dry at the time of restoration. In a similar manner, investigations herpetofaunal responses to forest management have focused on clearcuts, and less intensive stand manipulations are not as well studied. To evaluate community and population responses of reptiles and amphibians to hydrology restoration and canopy removal in the interior of previously degraded Carolina bays, I monitored herpetofauna in the uplands adjacent to six historically degraded Carolina bays in …
