Foraging Ecology And Depredation Impact Of Scaup On Commercial Baitfish And Sportfish Farms In Eastern Arkansas, Stephen Clements
Foraging Ecology And Depredation Impact Of Scaup On Commercial Baitfish And Sportfish Farms In Eastern Arkansas, Stephen Clements
Theses and Dissertations
Scaup (Aythya spp.) are suspected of consuming substantial quantities of fish from Arkansas commercial baitfish and sportfish farms. We investigated the foraging ecology and depredation impact of scaup on farms by surveying ponds and collecting scaup during two autumn-winters (2016-2018) in Arkansas. Scaup abundance and fish they consumed were highly variable between winters. More scaup were present and they ate more fish during the second winter (2017-2018) than the previous winter. In the second year, there were an estimated 874,941 scaup use-days and 18% of Lesser Scaup diet was fish. We found that scaup use of ponds was more likely …
Environmental Negotiations Cherokee Power In The Arkansas Valley, 1812-1828, Cane West
Environmental Negotiations Cherokee Power In The Arkansas Valley, 1812-1828, Cane West
Theses and Dissertations
In the early 19th century, the Arkansas River Valley existed as a borderlands region of powerful Indian nations and immigrant Euro-American and Native American settlers. In the resulting contests over settlement, Cherokee chiefs recreated the Arkansas Cherokees' ecological identity from hunters to agrarians to differentiate themselves from their Osage and white rivals. During the 1820s, Cherokee chiefs expanded on their agrarian rhetoric by appropriating American scientific systems in order to stymie white settlement. By the end of the 1820s, Arkansas Cherokee chiefs had infused their arguments of preferred agricultural lands, appropriate survey methods, and accurate cartography into the debates over …
The Role Of Expectations On Waterfowl Hunter Satisfaction, Kevin D. Brunke
The Role Of Expectations On Waterfowl Hunter Satisfaction, Kevin D. Brunke
Theses and Dissertations
Hunter satisfaction has received extensive attention in the literature, but the role of expectations on satisfaction has been neglected. Consumer satisfaction researchers often use the expectancy disconfirmation paradigm (i.e., differences between expectations and reality) to address relationships between expectations and satisfaction. I used this paradigm to examine the relationship between expectations and satisfaction for waterfowl hunters in Arkansas and Mississippi. I found hunter satisfaction was a partial function of fulfilled expectations in both studies. Performance-only measures generally correlated more strongly with overall satisfaction than disconfirmations measured by a difference score. Conversely, disconfirmation of expectations for a season measured on a …
Ecological And Genetic Consequences Of Seasonal Drought On Stream Communities Inhabiting Pool Refugia, Joseph William Love
Ecological And Genetic Consequences Of Seasonal Drought On Stream Communities Inhabiting Pool Refugia, Joseph William Love
Theses and Dissertations
In intermittent streams, hydrological variation is probably the single-most important factor affecting fish assemblage structure. While the response of aquatic assemblages to seasonal or annual variation in hydrology is well-known, less attention has been devoted to how assemblages respond to natural, intraseasonal drought. To explore this question, I conducted summer surveys of fish and aquatic insect assemblages occupying pool refugia in first to third order, intermittent streams in the Saline river drainage in the Ouachita highlands (central Arkansas, U.S.A.)(2001?2003). The goals of this project were: 1) to relate assemblage variability of fishes and aquatic insects to environmental gradients during summer …
