Sampling Terrestrial Arthropod Biodiversity: A Case Study In Arkansas, Michael Joseph Skvarla
Sampling Terrestrial Arthropod Biodiversity: A Case Study In Arkansas, Michael Joseph Skvarla
Graduate Theses and Dissertations
The Interior Highlands is a biodiversity hotspot, with at least 200 known endemic species, but is understudied compared to hotspots, such as the Southern Appalachians. In order to begin to rectify this issue, a nine month study was conducted from mid-March through early December at a 4 ha site at Steel Creek, Buffalo National River, in Newton County, Arkansas. Thirteen collecting methods were employed, including three colors of Lindgren funnel trap, five colors of pan trap, Malaise traps, canopy traps with upper and lower collectors, pitfall traps, and Berlese-Tullgren extraction of leaf litter, which resulted in the collection of 1311 …
Phylogenetic Analysis And Revision Of The Nearctic Androprosopa Mik (Diptera: Thaumaleidae) With An Emphasis On The Western Species, Robert John Pivar
Phylogenetic Analysis And Revision Of The Nearctic Androprosopa Mik (Diptera: Thaumaleidae) With An Emphasis On The Western Species, Robert John Pivar
Masters Theses
The family Thaumaleidae, also known as seepage midges, is an uncommonly encountered, understudied family of aquatic Diptera compared to its sister group, the Simuliidae. The goal of this project was to assess species diversity of the Nearctic Thaumaleidae and determine relationships among them. The western Nearctic fauna of Androprosopa Mik is revised to include twenty-eight species, six of which are described as new to science. Descriptions of the adult males of A. apache, A. arnaudi, A. magnipelvim, A. rainierensis, A. sierra and A. uvas are provided. Redescriptions of all remaining species are also provided, as well …
A Comprehensive Evaluation Of Benthic Invertebrate Communities In The Emory River, Watts Bar Reservoir, Tn, Suzanne Jane Young
A Comprehensive Evaluation Of Benthic Invertebrate Communities In The Emory River, Watts Bar Reservoir, Tn, Suzanne Jane Young
Masters Theses
The release of fly ash at the Tennessee Valley Authority (TVA) Kingston Fossil Plant (KIF) on 22 December 2008 discharged approximately 4.1 million cubic meters of coal ash into the adjacent aquatic and terrestrial systems. Previous benthic invertebrate investigations conducted by TVA and collaborative researchers concluded that benthic invertebrates in the Emory River were at moderate risk from ash-related constituents, primarily arsenic, in ash-contaminated sediment that remained in the Emory River following extensive dredging efforts. These conclusions were based on the observation of statistically significant reductions in growth and biomass in laboratory toxicity tests with Emory River sediment. Benthic invertebrate …
Flowers In Space Attacked By Aliens: Understanding The Spatial Ecology Behind The Devastating Damage By A Thistle Bud Weevil On Pitcher’S Thistle At Whitefish Dunes State Park, Wi, Zechariah D. Meunier
Flowers In Space Attacked By Aliens: Understanding The Spatial Ecology Behind The Devastating Damage By A Thistle Bud Weevil On Pitcher’S Thistle At Whitefish Dunes State Park, Wi, Zechariah D. Meunier
Lawrence University Honors Projects
One of the most threatened plants in the Great Lakes region is Pitcher’s thistle (Cirsium pitcheri), which inhabits sand dunes along the shorelines of Lakes Michigan, Huron, and Superior. In addition to risks from habitat loss and invasive species, C. pitcheri are imperiled by a thistle bud weevil (Larinus planus) that was originally distributed for biological control of nonnative thistles. During the summer of 2014, we empirically studied the devastating damage caused by L. planus on a population of C. pitcheri at Whitefish Dunes State Park, WI, to determine what factors influence the distribution and intensity …
The Relationship Between Manuscript Title Structure And Success: Editorial Decisions And Citation Performance For An Ecological Journal, Charles W. Fox, C. Sean Burns
The Relationship Between Manuscript Title Structure And Success: Editorial Decisions And Citation Performance For An Ecological Journal, Charles W. Fox, C. Sean Burns
Entomology Faculty Publications
A poorly chosen article title may make a paper difficult to discover or discourage readership when discovered, reducing an article's impact. Yet, it is unclear how the structure of a manuscript's title influences readership and impact. We used manuscript tracking data for all manuscripts submitted to the journal Functional Ecology from 2004 to 2013 and citation data for papers published in this journal from 1987 to 2011 to examine how title features changed and whether a manuscript's title structure was predictive of success during the manuscript review process and/or impact (citation) after publication. Titles of manuscripts submitted to Functional Ecology …
Short-Horned Grasshopper Subfamilies Feed At Different Rates On Big Bluestem And Switchgrass Cultivars, Muhammad Ullah, Fatima Mustafa, William W. Hoback, Mathew L. Brust, Kerri M. Farnsworth-Hoback, John E. Foster
Short-Horned Grasshopper Subfamilies Feed At Different Rates On Big Bluestem And Switchgrass Cultivars, Muhammad Ullah, Fatima Mustafa, William W. Hoback, Mathew L. Brust, Kerri M. Farnsworth-Hoback, John E. Foster
Department of Entomology: Faculty Publications
Grasshopper species belonging to subfamilies Melanoplinae, Gomphocerinae and Oedipodinae were tested for their feeding rate on three types of grass. All grasshopper species were offered Shawnee and Kanlow cultivars of switchgrass, Panicum virgatum L. and big bluestem, Andropogon gerardii Vitman. The grasshoppers, Melanoplus femurrubrum and Melanoplus differentialis were also tested for their feeding on turgid or wilted leaves of the Shawnee cultivar of switchgrass. We found that M. differentialis consumed more switchgrass compared to big bluestem while M. femurrubrum and Arphia xanthoptera consumed the most Shawnee switchgrass. The M. differentialis consumed more turgid grass compared to wilted switchgrass. The feeding …
Clues To Aquatic Beetle Research In Southeast Asia: A Multitude Of Ecological Niches, Microhabitats And Deduced Field Sampling Techniques, Hendrik Freitag
Clues To Aquatic Beetle Research In Southeast Asia: A Multitude Of Ecological Niches, Microhabitats And Deduced Field Sampling Techniques, Hendrik Freitag
Biology Faculty Publications
The basic ecological classification of Southeast Asian beetle families that are associated with aquatic habitats is reviewed. The microhabitat preferences of the taxa are examined on family level with generic examples. Suitable collection methods for quantitative and qualitative sampling are suggested which take into account the different ecological adaptation patterns and microhabitat preferences.
The Beetles Of The Lesser Antilles (Insecta, Coleoptera): Diversity And Distributions, Stewart B. Peck
The Beetles Of The Lesser Antilles (Insecta, Coleoptera): Diversity And Distributions, Stewart B. Peck
Insecta Mundi
The island arc of the Lesser Antilles lies at the eastern margin of the Caribbean Sea in the Western Hemisphere, and stretches from the eastern end of the islands of the Greater Antilles (at the Virgin Islands), south to a position near the continental islands of Trinidad and Tobago at the north eastern corner of South America. The islands are a part of the West Indian Islands biodiversity “hotspot” and have been available for terrestrial colonization for about the past 15 million years. This is a status report on present knowledge of the beetle faunas of these islands, which is …
