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 …
Effects Of Management Efforts On Fledging Success Of Endangered Interior Least Terns (Sternula Antillarum Athalassos) On The Mcclellan-Kerr Arkansas River Navigation System In Arkansas, Trevor N. Jensen
Theses and Dissertations from 2020
The Interior Least Tern (Sternula antillarum athalassos) is an endangered shorebird that primarily nests in colonies on barren riverine sandbars on many major river systems throughout the central United States. Water resource development projects such as damming and channelization have altered the natural flow regimes of these systems leading to a decrease in sandbar quality and quantity, and as a result this species is dependent on management to ensure their recovery. Managers within Arkansas have been applying a variety of management approaches to improve sandbar nesting habitat and success of this population intermittently since 2002, with increased intensity since 2015. …
