History, Nesting Population, Migration, Home Range And Habitats Used By Louisiana Bald Eagles, Nickolas Ryan Smith
History, Nesting Population, Migration, Home Range And Habitats Used By Louisiana Bald Eagles, Nickolas Ryan Smith
LSU Master's Theses
The population of Bald Eagles (Haliaeetus leucocephalus) nesting in Louisiana reached precariously low numbers in the early 1970’s, and although the population has since increased markedly, resident eagles remain a species of conservation concern in Louisiana. Using statewide aerial nest survey data from 1975–2008, I documented the history and quantified the recovery of the nesting population in Louisiana. Known active nests increased exponentially from 7 to 387 during this period, exhibiting a mean annual rate of increase of 11.1 ± 0.3% per year with no indications of slowing. By 1990, the nesting population in Louisiana had exceeded all goals of …
Population Characteristics Of A White-Tailed Deer Herd In A Bottomland Hardwood Forest Of South-Central Louisiana, Justin W. Thayer
Population Characteristics Of A White-Tailed Deer Herd In A Bottomland Hardwood Forest Of South-Central Louisiana, Justin W. Thayer
LSU Master's Theses
White-tailed deer are an important economic and recreational resource in Louisiana. A basic understanding of population dynamics is essential to ensure sound management, but baseline information in Louisiana is lacking. Likewise, the notion of Quality Deer Management (QDM) continues to gain momentum in Louisiana. Our objectives were to evaluate space use, survival, and mortality for a deer herd managed under a QDM regime in south Louisiana. We captured 65 deer in West Baton Rouge and Iberville Parishes during 2007 and 2008, radio-marked 37 males and 11 females, and ear-marked an additional 10 males and 7 females. Home ranges (95%) for …
Seasonal Space Use, Habitat Preference And Survival Of Female Wild Turkeys In A Louisiana Bottomland Hardwood Forest, Walker Blake Wilson
Seasonal Space Use, Habitat Preference And Survival Of Female Wild Turkeys In A Louisiana Bottomland Hardwood Forest, Walker Blake Wilson
LSU Master's Theses
Female wild turkeys (Meleagris gallopavo) were captured and radio-marked in a bottomland hardwood forest in south-central Louisiana. Turkeys were monitored using radio telemetry from fixed points on Sherburne Wildlife Management Area, Atchafalaya National Wildlife Refuge, and Bayou des Ourses to observe seasonal patterns of space use, habitat preference and survival from 2002-04. The largest mean seasonal home range of 902.87 ha occurred during preincubation (15 Feb – 9 Apr; n = 24) when females typically search for suitable nest sites, and the smallest mean seasonal home range was 434.12 ha, during brood-rearing (1 Jun – 30 Sep; n = 32) …
