Effects of Genetic and Environmental Variation in Solidago Altissima on Associated Arthropod Communities 2012 1570 A common garden approach was used to assess the potential for genetic and environmental variation in a Solidago altissima population to structure an associated insect community and influence the colonization of a dominant herbivore species. Distinct...
Effects of Prior Herbivory on Aphid Colonization of Solidago Altissima Clones 2012 2274 To determine the effects of genetic variation and initial herbivore damage on Solidago altissima and subsequent aphid colonization, I conducted a common garden experiment with greenhouse-grown clones induced by Trirhabda virgata. Seventy-five days af...
Spatial Analysis of Terpenes and Aphid Abundance in Solidago Altissima 2015 1218 This study explores the connection between plant chemistry, plant herbivores, and the environment in which plants are grown. Understanding interspecific, community-level interactions is an essential part of understanding ecosystems as a whole. As nat...
Insect Community Responses To Simultaneous CO2, Temperature, And Water Manipulation Within An Old-Field Ecosystem 2007 183 Climate change researchers have recently recognized a need to shift toward experiments that examine community-level responses to simultaneous exposure of multiple climate change factors (e.g. [C02], temperature, and/or water). Previousstudies have sh...
Solidago Altissima And Terpenes: Relationship With Insect Pollinators And Preferences 2022 253 The interaction between plants and insect pollinators plays an important role contributing to the biodiversity of terrestrial ecosystems. Flowers produce chemicals resulting in olfactory and gustation ques that largely contribute to these interaction...
The Effects Of Genotype And Spatial Scale On The Associated Pollinator Community Of Solidago Altissima 2016 743 Plant-pollinator interactions are among the most important mutualisms, as pollination is a necessary ecological service that contributes to the maintenance of biodiversity and ecosystem functioning. The plant Solidago altissima has been used to obser...
Vegetation Structure And Interspecific Interactions Predict Distribution And Abundance Of Solidago Specialist Aphids 2017 965 Volatile compounds such as terpenes are often used by plants as insect herbivory deterrents, though terpenes broadly act as semiochemicals, both priming nearby plants and providing host recognition for insects. I focused on the interactions of tall ...
The Effect Of Solidago Altissima Cytotypes And Soil Nutrients On Terpene Production, Leaf Nutrients And Uroleucon Nigrotuberculatum Abundance 2020 308 The specific factors that drive plant genotype choice by insects remain uncertain. I investigated the connection between tall goldenrod, Solidago altissima, cytotypes {diploid and hexaploid), phytochemistry (C, CN and terpenes) and soil nutrient leve...
Ground Beetles (Coleoptera: Carabidae) As Indicators Of Environmental Change In An Eastern U.S. Temperate Forest Subjected To Long-Term Precipitation Alterations 2007 212 To address how human-induced climate change could affect terrestrial ecosystem processes, I conducted an experiment at the Throughfall Displacement Experiment (TDE), Oak Ridge National Laboratory, TN, to examine how long-term precipitation alteration...
Aspects Of The Reproductive And Movement Ecology Of The Timber Rattlesnake (Crotalus Horridus) In The Upper Piedmont Of North Carolina: Conservation Management Recommendations With An Examination Of The Potential Vulnerabilities To Populations Threatened By New Roads 2006 203 Understanding the dynamics of movement in animals threatened by habitat alterations requires that structures such as roads be considered. I conducted a two-part study to better understand the impact of roads on populations and the conservation manage...
Pre- And Post-Fire Microarthropod Assemblages On Ridge, Cliff Face And Cliff Base Habitats Within The Linville Gorge Wilderness Area, North Carolina 2003 177 This study represents the first quantitative approach investigating microarthropod communities on vertical cliff faces. The study site was located on the Gold Coast Wall in the Linville Gorge Wilderness Area, Burke County, North Carolina. Comparisons...
