The elusive and nocturnal nature of the ocelot Leopardus pardalis poses difficulty in gaining basic information on demographic parameters needed to better inform conservation. My study used camera trapping data from long-term monitoring of ocelot populations on six different protected areas in Belize over a time span ranging from 1 to 12 years, with 1,700 ocelot detections in 65,157 total trap nights. I used classical and spatially explicit methods, including multi-session robust design, to estimate and compare ocelot density and survival across sites and time. Full likelihood single session models estimated densities ranging from 6.4 - 22.5 individuals/100km2 in the broadleaf forested sites. Robust design models estimated densities from 8.8 - 22.8 individuals/100 km2 and ocelots had high annual survival (71-79%) in 2 broadleaf sites. Contrary to predictions, robust design models had higher precision than full likelihood models less than half the time. Spatially explicit models estimated density ranging between 7.2 – 22.0 individuals/100 km2 in broadleaf sites, and much lower estimates at 0.9 individuals/100 km2 in the pine forest site. Accounting for sex in spatially explicit methods, which directly incorporate locations of captures into the model, increased precision in density estimates by reducing individual heterogeneity in capture probability. The spatial models also demonstrated that males moved larger distances than females and had slightly higher detection rates. Ocelot populations remained relatively stable over time at the long term sites. My study produced methodologically rigorous abundance/density estimates for ocelots in Belize and the first ever ocelot survival estimates. / Master of Science / The elusive and nocturnal nature of the ocelot <i>Leopardus pardalis</i> poses difficulty in gaining basic information on demographic parameters needed to better inform conservation.

The development of tourism and more importantly eco-tourism has emerged as a primary objective for the government of Belize, Central America. This study examines two villages Seine Bight and Placencia located on a peninsula occupied by separate ethnic groups (Garifuna and Creole) that is located on a peninsula in Southern Belize. Seine Bight and Placencia are undergoing a change in economic activity to tourism. The study attempts to understand the role of ethnicity, socio-economic status, amount of contact with tourists, and the environment in regard to attitudes towards tourism utilizing quantitative and qualitative methods. The study also attempts to understand the organization and disorganization of productive activity on the peninsula and ethnicity over space and time. The point of diffusion and contact of different groups is reflected archeologically and historically in the marine landscape. The peninsula served not only as a natural harbor for those sailing up and down the coastline over time but also served as a point of diffusion of different groups reflected in changing place names, such as Placentia, Point Patient, and Pasciencia.

As communities and managers become aware of the long-term impacts of mangrove loss, estimated at 1-2% per year, interest in sediment erosion and mangrove rehabilitation has increased substantially. In this thesis project I 1) examine erosion rates within coastal fringing Rhizophora mangle ecosystems following mangrove clearing and compare these rates to accretion rates in intact mangroves; and 2) investigate the abiotic factors influencing mangrove seedling survival and regeneration of naturally colonizing R. mangle, in historic mangrove habitat after anthropogenic clearing. Differences in erosion were compared between patches of open-coast intact and anthropogenically cleared R. mangle to quantify the sediment trapping function provided by mangroves and its loss following clearing over a 24 month period. Growth rates of mangrove seedlings in intact forest were compared to seedlings in cleared areas. Seedling growth indicators were measured on 100 seedlings at five sites (50 in the intact and 50 in the cleared areas). To examine the limiting factors on seedling growth rates, nutrient addition and wave protection treatments were applied to seedlings in three disturbed areas. Sites within intact mangroves had sediment accretion (M= +3.83 mm) while areas cleared of mangroves had sediment erosion (M= -7.30 mm). Seedling growth (height) over the 2 year study period significantly differed between intact mangrove (M = 15.6 cm) and cleared (M = 10.24 cm) areas. Seedling mortality from the cleared areas (31%) differed from the intact areas (13%). Average seedling growth (height) was: greater with both nutrient/wave (M = 18.4 cm) and nutrient (M = 17.65 cm) treatments compared to controls (M = 10.8 cm), which suggests that providing nutrients and/or wave protection result in growth outputs comparable to seedlings found in intact mangroves. This study may prove to be useful in identifying areas that are most vulnerable to erosion following mangrove removal and ideal location of restoration following mangrove removal. Areas cleared of mangroves can lead to intensified erosion in areas where fringing reefs are not continuous. When managers are determining areas to focus resources for restoration, focusing on areas with nutrient rich habitat may result in higher survival rates and growth outputs.

Analysis of lithics, particularly flake debitage, from a small Preclassic Maya community provides data bearing upon the manufacture and distribution of stone tools in the northern Belizean region during the Middle and Late Preclassic eras. These data suggest a complex relationship among contemporaneous communities with regard to raw material and tool acquisition and manufacture. There is no evidence of monopoly of raw material resources by any one group; rather, a mixed pattern is seen involving distribution both of partly processed raw material and of certain finished formal tool types. These formal types, as well as befaces in general, are seen to be increasingly important through time, possibly related to changing agricultural practices. While no conclusions can be drawn on the basis of presently available lithic data as to the nature of the Preclassic regional lithic distribution system, ethnographic and archaeological analogies are used to suggest some possible economic scenarios.

Traditionally, the analysis of ceramics has played a major role in archaeological research the world over, and this is particularly true in the Maya area where until recently ceramic studies have been used for the sole purpose of chronological ordering. This dissertation discusses the historic development of ceramic research in Maya archaeology, as well as documenting the present role of ceramic analyses, as preface to the analysis of the ceramics from Cuello, a small site in northern Belize. Excavations at the site indicate that the area under study, Platform 34, was occupied from the Early Formative at about 2,000 b.c. until the Late Formative at about a.d. 250, when Platform 34 was apparently largely abandoned, although other areas of the site continue to be occupied. The analysis of the ceramics from Cuello proceeds utilizing the traditional type: variety classification system to order the ceramics chronologically. The Cuello typology, in accordance with the major period of occupation of Platform 34, spans a period of time beginning in the Early Formative with the Swasey Complex, and ending in the Late Formative with the Cocos Complex. While some typological comparisons of ceramics among sites in the Maya Lowlands are made to place Cuello securely within a chronological framework, the main thrust of the analysis is to understand intra-site ceramic variability. Unlike earlier maya ceramic analyses, the present one continues with a vessel form classification, since forms are considered sensitive indicators of functional variability within the site. It is shown, through this analysis, that ceramic analyses are useful for more than chronological ordering,and when ceramic variability is examined within the archaeological contexts in which the ceramics are found, has the potential of informing on functional and social patterns on an intra-site level.

Research at the site of San Estevan, Belize begins with the premise that more serious attention must be paid to the significance of residential variability in archaeological modelings of the lowland Maya. A classification of structure groupings is used to track the distribution of San Estevan's diverse residential arrangements across the site. Norms of social structure and economic inequality prove inadequate frameworks to account for the spatial and temporal variation manifest by San Estevan's residential classes, nor do they help to explain the spatial regularities underlying the distributions of these classes. I suggest, instead, that the site's residential units best effect divergent organizational strategies adopted by San Estevan's prehispanic domestic groups. Whereas diffuse political authority, impoverished political economies, and kingroup self-sufficiency traditionally have been invoked to account for Maya residential patterns, domestic strategies at San Estevan gained their shape directly in relation to the functions housed in the community's precincts of monumental architecture. I conclude that prehispanic Maya residential distributions formed through stringent economic and political entailments of community life.
