The Impacts Of Prescribed Burning And Mechanical Thinning On Insect Communities In The Arkansas Ozarks, Aaron P. Tormanen
The Impacts Of Prescribed Burning And Mechanical Thinning On Insect Communities In The Arkansas Ozarks, Aaron P. Tormanen
Theses and Dissertations from 2020
Insects are important in woodland ecosystems due to their role as pollinators and as prey for bats. My research investigated the relationships between forest management, vegetation, and insects in the Ozark National Forest in Arkansas. I selected 30 stands burned at varying frequencies in the last 12 years. Twelve of these stands were burned and mechanically thinned, 12 were only burned, and 6 were untreated. I deployed blacklight traps and malaise traps in each stand monthly from mid-March to mid- November 2019. Over 42,391 insects were collected, and Lepidoptera was the most abundant order. Insects were dried, weighed, and identified …
Mesopredator Distribution, Abundance And Potential Competition With The American Burying Beetle (Nicrophorus Americanus) At Fort Chaffee Joint Maneuver Training Center, Karisa Fenton
Theses and Dissertations from 2019
The American burying beetle (Nicrophorus americanus, hereafter ABB) was listed as an endangered species in 1989 and many hypotheses have been developed to explain their rangewide decline. I investigated the carcass competition hypothesis that implicates increased competition between vertebrate scavengers and ABBs for appropriate-sized carcasses as a cause for ABB decline. Predators of medium size that occupy an intermediate trophic level (hereafter mesopredators) are potential competitors for carcasses. I used camera trapping to assess mesopredator abundances in nine different habitats at Fort Chaffee Joint Maneuver Training Center (FCJMTC) in western Arkansas because this area supports the largest known population of …
