Abundance and distribution trends of the West Indian manatee in the coastal zone of Belize: implications for conservation.

Auil, Nicole Erica 30 September 2004 (has links)
The coastal zone of Belize is home to the largest recorded number of the threatened Antillean manatee (Trichechus manatus manatus) within the species' Caribbean range. The objectives of my study were: (1) to determine long-term trends in aerial survey counts and indices of the manatee population in the coastal zone of Belize; and (2) to examine the seasonal change in manatee distribution among habitats in the coastal zone. Standardized extended-area aerial surveys were conducted along the entire coastline of Belize in the dry and wet seasons of 1997, and 1999 - 2002. Manatees were counted in five habitat categories: cay, coast, estuary, lagoon, and river. Total sightings per survey ranged from 90 to 338; the greatest number was counted in the 2002 wet season. Calf percentage ranged from 5 to 13. A slight negative trend in total counts was significant for dry-season, not wet-season surveys, indicating an interactive effect of season and year. Based on analysis of variance, the Abundance Index (transformed manatee sightings per hour) did not differ significantly among years, although it varied significantly within year by season and habitat by season. In applying a spatial approach, the general survey route was buffered 1 km on both sides, and 1 km grids were overlaid and classified by habitat type. The presence or absence of each cell for each survey was used in likelihood ratio tests of the single and interactive effect of season and habitat. The Index for river habitat was higher in the dry season, while cay habitat was higher in the wet season. Overall, near-shore habitat (estuary, lagoon, and river) showed a higher Index than did the offshore habitat (cay and coast) although the total number of sightings was higher offshore. Considering the interactive effect of year, season, and habitat, long-term studies are needed, in both seasons, and among all habitats to account for variation. Continued broad-scale surveys, along with metapopulation analysis would fine-tune the understanding of specific sites, enhancing integrated coastal zone management for protected species and their habitat systems.

Preclassic Maya funerary patterns in northern Belize : an analysis of interment attributes from Colha, Cuello, and K'axob

Obledo, Micaela Nerio 26 January 2012 (has links)
This dissertation presents an analysis of Preclassic period (1000 B.C. – A.D. 250) funerary attributes of three Maya sites in northern Belize, Central America: Colha, Cuello, and K’axob. The dataset is comprised of 133 interments from Colha, 131 interments from Cuello, and 98 interments from K’axob for a total of 362 Preclassic interments. Analysis has been conducted on a suite of 12 variables representative of this dataset and their interrelatedness: age, sex, artifact material type, artifact material form, cranial orientation, burial position or posture, functional designation of architecture in which an interment is placed, presence or absence of indications of burning, presence or absence of red mineral pigmentation, functional designation of artifacts, presence or absence of a cross motif, and presence or absence of a head cover (vessel covering the cranium). This research project has four main objectives: 1) provide a structured presentation of Preclassic interment data for Colha, Cuello, and K’axob, 2) present a thorough and cogent analysis of the interrelatedness of the suite of variables abovementioned, 3) document any significant trends and anomalies that are evidenced within the funerary attributes of these sites, and finally 4) to offer an interpretation of those patterns and deviations seen within the analysis as they relate to intrasite and intersite social differentiation and dynamics through the Preclassic. The analysis within this volume demonstrates that the elaboration and variation of interment attributes increase over time in Preclassic at the three sites of study. This is paralleled by a development of ritual and ceremonial architecture for public activities. Differential access to materials and forms is indicated throughout the Middle, Late and Terminal Preclassic, with the level of disparity between the apparent elite and non-elite increasing over time. Adult males are generally accompanied by higher numbers and a greater variety of goods than are females and subadults. This indicates a power and/or status differential between the two sexes and age groups, with male adults being the most highly esteemed individuals within the social stratification system. This study demonstrates the dynamic and multifaceted material representations with which Preclassic Maya of Northern Belize expressed their identity in death. / text

Shifting Allegiances at La Milpa, Belize: A Typological, Chronological, and Formal Analysis of the Ceramics

Sagebiel, Kerry Lynn January 2005 (has links)
The primary goal of this dissertation is to present an outline of the culture history of the site of La Milpa and its immediate sustaining area through the elaboration and elucidation of a ceramic chronology and typology. However, an equally important aspect of this dissertation is a thorough critique of the type-variety/mode (T-V) system of classification upon which Maya ceramic analysis has been based over the last forty years. The analysis presented here was completed using a relational database (Microsoft Access). By using this database program, it became clear that it is necessary to rethink the basis and use of the type-variety system and how (or whether) it can be adapted as a tool for use in database driven analysis.

Teachers' classroom practice : emic interpretations of teaching English in Belize's secondary schools

McMillan, Deborah E. January 2003 (has links)
This study was designed to gather the meaning-perspectives and interpretations teachers gave to their language teaching practice using their voice and the voice of learners. The complex and paradoxical language situation in Creole-speaking communities like Belize has been well documented by researchers and linguists including Craig (1978), Roberts (1994), Robertson (1997), and Young (1995). There are a number of education reports on the English language teaching situation at the primary school level in Belize; however, very little attention has been given to English language teaching at the secondary level. In this study, the teachers' practice was examined using Clandinin's (1985), Elbaz's (1983), and Jarvis's (1999) definitions of teachers' knowledge. Nespor's (1987), Pajares' (1992) and Richards and Lockhart's (1996) articles and research on teachers' beliefs served as theoretical support on the role and importance of beliefs in teachers' practice. The language teaching strategies offered by Kumaravadivelu (1994), and those recommended for bidialectal communities by Corson (1997), Craig (1978), Robertson (1995), Rubinstein (1977), Sato (1989), and Young (1995) were used to compare the strategies found in the data.Two secondary school teachers and two students participated in the study. Data were gathered using short teacher questionnaires, teachers' lesson plans, pre-observation and follow-up interviews with teachers, audio-taped and video-taped class observations, stimulated recall sessions with teachers and students, and the researcher's field notes and reflective journal. The analysis of data produced four themes: (a) teachers' English language practice, (b) teachers' knowledge about their practice, (c) teachers' pedagogical beliefs, and (d) the learners' voice: the other perspective.The study's findings suggest that the teachers' personal, practical, and situated knowledge resides in their practice. A practice informed by their pedagogical beliefs, and reflected in the choice of English language teaching strategies developed from a complex fusion of pedagogical beliefs, learner needs, and the sociolinguistic context. The findings did not support the view that English language teachers are ill-prepared for the bidialectal situations in Creole communities, nor were the teachers poor models of English. This study will contribute to the understanding of English language teaching in Belize's secondary schools. / Department of Educational Studies

Good Men Grow Corn: Embodied Ecological Heritage and Health in a Belizean Mopan Community

Baines, Kristina Linda 01 January 2012 (has links)
Recent developments in land rights and land use in the Toledo district, Belize has generated anthropological and activist interest surrounding traditional ecological knowledge and practice, and the role of heritage in communities. This study explores the connection between ecological knowledge and practices, and the concurrent construction of heritage, and community health and wellness, broadly defined. Developing and using the concept of "embodied ecological heritage," this dissertation takes a phenomenological approach to understanding the convergence of ecological heritage and health in multiple realms of everyday life, arguing that lived experience of participating in "traditional" practices is fundamentally connected to wellness in the Mopan community of Santa Cruz. Using the results of ethnographic research using multiple methodologies across 76 households over a period of 11 months, this dissertation presents a detailed account of how Mopan Maya participants view ecological skill and knowledge as critical to being and living well, arguing that social factors, such as work and food choices, have an effect on wellness. The research contributes to a growing number of studies linking changes in the body and overall health status to everyday practices within communities. Outlining how certain knowledge and particular practices, such as exchanging labor and making baskets, become prioritized as heritage through both their conceptualization and deployment, the analysis centers on individual bodies as the foci of skill, sensory experience and change. The timely nature of making these connections explicit is discussed in light of ongoing "development" in Maya communities and beyond, with an illumination of how changing land use patterns have far-reaching effects on wellness from multiple perspectives; individual, social, ecological and political, and concluding that a consideration of wellness can benefit from looking at the processes involved in heritage construction as it relates to ecological practice.

A Paleoethnobotanical Perspective on Late Classic Maya Cave Ritual at the Site of Pacbitun, Belize

Parker, Megan 12 August 2014 (has links)
This thesis presents the results of paleoethnobotanical investigations conducted at nine karst sites associated with the Maya site of Pacbitun in western Belize. The archaeobotanical remains were deposited during the Late Classic period and the site was abandoned at some point during this same time (c. A.D. 900). Paleoenvironmental data from the Maya Lowlands indicates that human activity contributed to regional climate change during the Late/Terminal Classic period. However, site-specific research has demonstrated a variety of responses to these social and ecological changes. The archaeobotanical data from this study is used as a proxy for understanding how people at Pacbitun ritually responded to macro-regional environmental stress. Ritual plant use at the cave sites does not conform to behavioral ecology models that predict biological, cost-fitness related responses to resource scarcity. Instead, the data supports a model of behavior based on culturally motivated ritual practices.

Collectively coming to know: an ethnographic study of teacher learning in Toledo, Belize

Achtem, Janice 06 April 2010 (has links)
In this ethnographic case study I examine the meanings and manifestations of teacher knowledge by inquiring into the perceptions of learning for a group of primary school teachers in Toledo, Belize, Central America. As an outsider, I construct an insider’s view of teachers’ knowledge by representing what these teachers know about teaching and how they have come to know what they know. The lived experiences of the teachers are illuminated as I discuss opportunities and challenges for educators in this region of the world. The insider-outsider relationship is examined as I reflect on my role as a volunteer with a non-profit organization, as well as a researcher and a Canadian secondary school teacher. The following questions structure the study: (1) How does the development of teachers’ knowledge occur in rural communities of the majority world country of Belize? (2) What kind of impact has the Teachers for a Better Belize (TFABB) “Literacy Coaches Program” had on the development of teachers’ knowledge in Toledo, Belize? Results of the study are represented in three distinct ways. The creative ethnography highlights the lived reality of local teachers as I interpreted the typical journey they take in learning to teach. The realist tale, including several detailed participant quotes, illustrates a more explicit map of teacher learning as it connects with current research and literature. The confessional tale represents my highly personal reflections with regard to the research as well as my own learning. Toledo teachers identify many factors affecting their formal learning including economic constraints, geographic isolation and limited resources. Local teachers do, however, recognize and engage in the less formal learning opportunities available to them. They collaborate with peers, seek out mentors, engage in teacher workshops, and reflect on their own practice. An oppressive cloud, however, looms over the educational landscape in Toledo, as teachers describe tacit yet lingering effects of colonialism present in their educational culture. In this study I conclude that to realize improved opportunities for both teachers and students in Toledo, there must be genuine understanding and respect between all educational sectors. By raising the profile of the underrepresented primary teacher in Toledo, this study aims to promote meaningful dialogue between all those involved to nurture the professional knowledge development of teachers.

Diet of the Antillean Manatee (Trichechus manatus manatus) in Belize, Central America

Allen, Aarin Conrad 01 January 2014 (has links)
Belize has been identified as an important location for Antillean manatees (Trichechus manatus manatus), harboring the highest known population density of this subspecies. Information about their dietary habit is important in determining habitat requirements and aiding in conservation efforts. The main objective of this study was to identify the key plant species consumed by manatees in Belize and to establish differences in diet based on location, sex, size classification, and season. Samples were collected from two different locations within Belize where manatees are known to aggregate: Southern Lagoon and the Drowned Cayes off of Belize City. The contents of thirteen mouth, six digestive tract (stomach, duodenum and colon), and 124 fecal samples were analyzed. Five species of seagrasses (Halodule wrightii, Thalassia testudinum, Ruppia maritima, Syringodium filiforme, and Halophila sp.) made up the highest percentage of plants consumed; undigested rhizome was most prevalent. A vascular plant, the red mangrove (Rhizophora mangle), was identified as an important food item of manatees in Belize. Algae (Chara sp., Lyngbia sp., and Ulvasp.) and invertebrates (diatoms and sponges) were represented as well. These items are comparable to other reports of manatee diets in areas near Belize and areas with similar habitat. Variation in the percentage of seagrass, mangrove, and algae consumption was analyzed as a 4-factor factorial Analysis of Variance (ANOVA) with main effects and interactions for locality (Southern Lagoon and the Drowned Cayes), sex, size classification (>245 cm & ˂245 cm), and season (December – May and June – November). Sex and season did not influence diet composition; differences for locality and size classification were observed. Seagrass was more often consumed in Southern Lagoon (P = 0.03), whereas mangroves and algae were more prevalent in the Drowned Cayes (P = 0.03). No differences among size classifications in consumption of seagrasses or mangroves were observed. A significantly higher number of samples from adults (>245 cm) than juveniles (˂245 cm) contained algae (P = 0.04). This is most likely attributed to inexperience in foraging. Findings from these results suggest that diet composition analysis can be used to interpret Antillean manatee habitat and resource utilization and can aid in the conservation of this endangered species.
