Effects Of Food Plots On Selected Growth Parameters, Productivity, And Harvesting Of White-Tailed Deer In A National Forest., Kenneth Dale Dancak
Effects Of Food Plots On Selected Growth Parameters, Productivity, And Harvesting Of White-Tailed Deer In A National Forest., Kenneth Dale Dancak
LSU Historical Dissertations and Theses
A total of 8.1 ha of warm-season and 16.8 ha of cool-season food plots were installed on 2 of 4 study units at National Red Dirt Wildlife Management Preserve, Louisiana, an area managed by the USDA Forest Service for multiple resources. Mean ($\pm$ s.e.) study unit size was 2220 $\pm$ 246 ha. No food plots were installed on the remaining 2 study units (controls). Warm-season food plots were planted with American jointvetch (Aeschynomene americana); cool-season plots were planted with red clover (Trifolium pratense), subterranean clover (Trifolium subterraneum), winter wheat (Triticum aestivum) and white clover (Trifolium repens). All plots were maintained …
Habitat Use, Movements, And Behavior Of Shiny Cowbirds In Southwestern Puerto Rico., Paul Michael Mckenzie
Habitat Use, Movements, And Behavior Of Shiny Cowbirds In Southwestern Puerto Rico., Paul Michael Mckenzie
LSU Historical Dissertations and Theses
Shiny Cowbirds were primarily located in six major areas of concentration. Of these, all but one was in mesquite woodland. Overall, cowbirds used mesquite woodland almost 75% of the time but use of this habitat varied among weekly periods and was linked to rainfall received during weekly periods prior to the observation. Habitat use of cowbirds and the time they spent eating particular prey items were most correlated with total rainfall received 2-5 weeks prior to the observation (p =.0067 and p =.0149, respectively). Major food items taken by cowbirds following periods of sufficient rainfall were caterpillars, berries and grass …
Brugia Pahangi: Effects Of Maternal Filariasis On The Responses Of Their Progeny To Homologous Infection., Stephen Carl Bosshardt
Brugia Pahangi: Effects Of Maternal Filariasis On The Responses Of Their Progeny To Homologous Infection., Stephen Carl Bosshardt
LSU Historical Dissertations and Theses
The effects of in utero and neonatal exposure to maternal Brugia pahangi infections on the development of homologous infections, immune responses, and pathologic lesions was studied in age-matched progeny of infected and uninfected female jirds. High IgG antibody titers to B. pahangi antigens were present in the sera of progeny from infected mothers. These neonatal titers to homologous antigens were shown to be of maternal origin, and did not alter the cellular responses of uninfected progeny as measured by in vitro antigen-stimulated blastogenesis and in vivo pulmonary granulomatous inflammatory responses to antigen-coated beads. Studies were conducted to measure age-related differences …
Ecology Of Small Insectivorous Birds In A Bottomland Hardwood Forest., Wylie Clark Barrow Jr
Ecology Of Small Insectivorous Birds In A Bottomland Hardwood Forest., Wylie Clark Barrow Jr
LSU Historical Dissertations and Theses
Changes in species composition and abundance, habitat use patterns and foraging behavior of 19 bird species in a bottomland hardwood forest in Louisiana were studied during the 1984-1989 breeding seasons. Species that used only one macrohabitat included the Yellow-throated Warbler along oxbow lake margins and the American Redstart, Swainson's Warbler, and Hooded Warbler in non-flooded oak-gum-elm forest. The Northern Parula and Kentucky Warbler used 2 macrohabitats--non-flooded forest and oxbow lake margins. Thirteen species used 3 macrohabitats (non-flooded forest, seasonally flooded forest, and oxbow lake margins). I distinguished 6 groups of species that used similar microhabitat and foraging behavior. Ecological partitioning …
Effects Of Artificial Mineral Licks On White-Tailed Deer., Stephen Redmore Schultz
Effects Of Artificial Mineral Licks On White-Tailed Deer., Stephen Redmore Schultz
LSU Historical Dissertations and Theses
A commercial mineral mixture for deer was used to evaluate the effects of broad-spectrum dietary mineral supplementation on white-tailed deer (Odocoileus virginianus) growth, antler development, and tissue mineral content. Forty-two artificial mineral licks for deer were established on 3 study areas in East Feliciana Parish, Louisiana. All licks were monitored monthly, recharged to original level if used, and mineral consumption recorded from May 1988 through December 1989. Consumption data were converted to estimated average per deer values based on population estimates. Effects of artificial lick mineral consumption on free-ranging deer were examined by comparing deer harvested during the 1988-89 and …
