Assessing Landscape-Level Impacts Of Red Imported Fire Ants On Native Faunal Communities In Pine-Dominated Forests, Keri Elizabeth Landry
Assessing Landscape-Level Impacts Of Red Imported Fire Ants On Native Faunal Communities In Pine-Dominated Forests, Keri Elizabeth Landry
LSU Master's Theses
Since the accidental introduction of red imported fire ants (Solenopsis invicta Buren, RIFA) into Mobile, Alabama in the 1930’s, the invasion of this species into other areas across the southeast has increased drastically. RIFA have been implicated in the disruption of ecosystems and decreases in biodiversity. Most research on effects of RIFA on vertebrates and invertebrates have focused on small spatial scales and single species. I examined established populations of RIFA in relation to native ground-dwelling arthropods and small mammal communities in longleaf-pine and pine-hardwood forests. I evaluated the efficacy of using Amdro® to control RIFA and determined the effect …
Individual And Landscape-Level Effects Of Selective Herbicides, Mowing, And Prescribed Fire On Habitat Quality For Northern Bobwhite (Colinus Virginianus), Charles Lynn Kitts
Individual And Landscape-Level Effects Of Selective Herbicides, Mowing, And Prescribed Fire On Habitat Quality For Northern Bobwhite (Colinus Virginianus), Charles Lynn Kitts
LSU Master's Theses
Northern bobwhite (Colinus virginianus) populations have been declining throughout their range during the past 30 years primarily because of a result of loss of early successional habitat. Specifically, intensive silviculture practices and reduction in the use of prescribed fire has led to this loss. I studied effects of management practices (selective herbicides, mowing, and prescribed fire) on male and covey distribution, and brood-rearing habitats on Jackson-Bienville Wildlife Management Area (JBWMA). Specifically, I used calling surveys to assess landscape characteristics associated bobwhite distribution. I also measured vegetation and arthropod response, using imprinted bobwhite chicks, pitfalls, and sweep nets, to different habitat …
