11	Population Status and Evaluation of Landscape Change for the Lower Keys Marsh Rabbit Schmidt, Jason Alan 2009 December 1900 (has links) Wildlife biologists and land managers tasked with the recovery of the endangered Lower Keys marsh rabbit (LKMR; Sylvilagus palustris hefneri) were in need of a current population estimate as well as a method to estimate the LKMR population annually. Habitat loss and fragmentation from population growth and development have threatened the existence of the LKMR. Establishing and understanding long-term habitat availability for the LKMR is important for determining causes of historical population declines as well as designing and implementing successful recovery plans. I conducted a range-wide pellet survey and a mark-recapture study to estimate the LKMR population. I evaluated the fit of 5 models and considered the variation in behavioral response model the best model. I correlated (r2 = 0.913) this model's rabbit abundance estimates to pellet density in 11 patches and generated a range-wide population estimate of 317, a western clade population of 257, an eastern clade population of 25, and translocated LKMR populations of 35 and 0 on Little Pine and Water keys, respectively. This prediction equation provides managers a quick, efficient, and non-invasive method to estimate LKMR abundance from pellet counts. To quantify the amount of habitat loss and fragmentation that occurred over the last 50 years, I systematically delineated and compared potential LKMR habitat using 1959 and 2006 aerial photographs. Additionally, I investigated if other factors could have reduced the amount of suitable habitat available for the LKMR with a comparison of habitat loss and fragmentation on a developed island and an undeveloped island. Range-wide, I found that number of habitat patches increased by 38, total class area decreased by 49.0%, and mean patch size decreased by 44.3%. Mean shape index increased by 4.2% and mean proximity index decreased by 13%. Both the 1959 and 2006 connectance indices were low while the 2006 set decreased 12.1%. I observed the same patterns of habitat loss and fragmentation on both the developed and undeveloped islands as I did in the range-wide landscape analysis. I found that LKMR habitat has declined in area and become more fragmented over the last 50 years. Habitat loss and fragmentation by development have directly endangered the LKMR; however, sea level rise and woody encroachment also could have historically caused habitat loss and fragmentation. Although development in LKMR habitat was halted, sea-level rise and woody encroachment could continue to alter LKMR habitat.

12	A demographic analysis of Late Bronze Age Canaan : ancient population estimates and insights through archaeology Kennedy, Titus Michael January 2013 (has links) This thesis is a demographic analysis of Late Bronze Age Canaan (ca. 1550/1500-1200/1150 BCE), undertaken through the use of archaeological and anthropological data. The purpose is to establish estimates for the settlement population, nomadic population, nuclear family size, house size, sex ratio, and life expectancy of the people of Canaan during the Late Bronze Age. Previous studies have not addressed these issues in detail, nor had data from the entire scope of Canaan been considered, nor had a precise methodology been developed or used for estimating specific settlement populations and nomadic populations for Canaan during the Late Bronze Age. Thus, additional aspects of the thesis include the development and use of a new methodology for estimating ancient populations and a database of all of the Late Bronze Age sites in Canaan—both archaeological and textual. To accomplish these goals, the thesis uses archaeological data from excavations and surveys, texts from the Late Bronze Age, human skeletal remains from Late Bronze Age burials, demographic and ethnographic studies of various types of nomads, and methods, techniques, and observations from previous relevant studies. The primary objectives are to 1) obtain individual settlement, nomadic, and total population estimates for Canaan in the Late Bronze Age that are as accurate as possible based on the currently available data, along with additional demographic estimates of life expectancy and sex ratio, 2) propose a new methodology for estimating settlement populations in the ancient world, 3) present a catalogue and map of all of the sites in Canaan that were inhabited during the Late Bronze Age, 4) illuminate demographic trends during the Late Bronze Age in Canaan. The implications of the results may lead to a modified demographic view of Canaan and its sub-regions during the Late Bronze Age. / Old Testament & Ancient Near Eastern Studies / D. Litt. et Phil.
