Evaluating above- and belowground effects of native and non-native earthworms in grasslands
(2021-07)
Previous research has shown non-native earthworms can alter ecosystem function and structure by altering plant communities, soil dynamics, and soil microbial functional groups, including disruption of arbuscular mycorrhizal ...
Population genetic analysis of invasive Rattus: Implications for evolutionary biology, disease ecology and invasion biology
(2012-05)
Scope and Method of Study: I utilized population genetic analyses to examine the colonization history and contemporary dispersal patterns of invasive Rattus in the U.S., as well as identifying any evolutionary impacts of ...
Assessing the use of imagery from sentinel-2 and an unmanned aerial vehicle to monitor Nymphoides peltata in an Oklahoma reservoir
(2020-05)
Remote sensing of aquatic invasive plants has been relatively understudied for treatment monitoring applications. Invasive aquatic plants cause ecological distress as well as millions of dollars in damages and lost utility ...
Native Legumes Versus Lespedeza cuneata: Implications for Ecosystem Services
(2019-07)
Grasslands are the most threatened ecosystem worldwide due to habitat fragmentation and alteration, which have contributed to the spread of invasive plants. Fire is historically important in maintaining grasslands, and can ...
Implications of pyric-herbivory on central North American grassland ecology, management and production
(2014-07)
The interaction of fire and grazing is an ecological process regulating fire-dependent ecosystems. Prior to European settlement, grasslands were regulated by fires and focal grazing by herbivores (pyric-herbivory), a ...
Non-Native Black Bass: Potential Conflicts in Fisheries Management
(2019-05-01)
Black bass (Micropterus spp.) are among the most highly sought after recreational fishes around the world, which has resulted in widespread introductions outside of their indigenous ranges. Non-native black bass can, ...
Sericea lespedeza (Lespedeza cuneata) invasion: Implications for a small mammal community and the influence of local fire history
(2013-12)
Lespedeza cuneata [(Dumont) G. Don] is a perennial legume first introduced to North America from eastern Asia in 1896 and is now widespread and well established across much of the eastern and central United States. Possible ...
Identification of grain sorghum resistance to sugarcane aphid and field test response by Hymenoptera to honeydew
(2020-07)
Grain sorghum, Sorghum bicolor, is one of the most important crops worldwide as it can be used for human consumption, biofuel, and livestock feed. In 2013, the sugarcane aphid, Melanaphis sacchari (SCA), switched host ...
