Effects of Landscape Disturbances on Autotrophic Processes Within Arkansas Ozark Streams
… abiotic and biotic processes within surrounding streams. For example, streams in agricultural and urban watersheds receive greater light and nutrient inputs that can promote increased algal growth and primary production. Natural gas (NG) infrastructure development, a recent land use change in …

A Method Comparison and Stressor-Response Experimental Study of Nitrogen and Phosphorus Impacts to Periphyton in Ozark Streams
… experiment were conducted in the southern Ozarks of Arkansas. The method comparison study was implemented using two common bioassessment procedures (whole-surface and delimiter-reduced periphyton removal) to assess the potential for combining datasets. During the manipulative experiment, …

Effect of Macrograzers (Campostoma spp. and Faxonius spp.) on Periphyton in Ozark Streams with Considerations Given to Macrograzer Biomass, Phosphorus, and Season: Mensurative and Manipulative Studies
… between nutrients and periphyton biomass in streams. I conducted a mensurative field study to determine if stoneroller and crayfish abundance related to algal biomass at varying nutrient concentrations and manipulated macrograzer presence with electrical exclosures in streams to examine …

Size-Selective Predation By Ringed Crayfish (Orconectes Neglectus) On Native And Invasive Snails
… field surveys of snails and crayfish in three Ozark streams, plus a series of four lab experiments to determine feeding rates and prey preference by O. neglectus on these three snail species. Elimia potosiensis was often observed living near crayfish, but was rarely consumed regardless of snail …

Effects of Trout Introduction on Community Assemblage and Behavior of Native Fish in the Missouri Ozarks
Salmonids have been introduced to Ozark streams since 1878 with few studies to date investigating the effects of trout introduction on native fish. Fish communities were sampled in the fall of 2013 to assess potential impacts of trout introduction on community assemblage and behavior of native …

A Comparison of Water Quality Analyses and the Index of Biotic Integrity in Bull Creek, Southwest Missouri
… suggest determining the ecological integrity of streams is best achieved by an integrative approach measuring both chemical and biological parameters. The data presented in this thesis also show that Ozark streams such as Bull Creek are losing their classifications as pristine streams. The Index …
