Using ethnomethodology and influenced by ethnography, the purpose of this research has been to explore the meanings that elder residents in and around Hafford, SK and Val Marie, SK derive from their relationship with and confer upon their cultural landscapes. Hence, for a month and a half, I lived in Hafford and then Val Marie in order to speak with elder residents (age 60 or over) who have lived and worked in or around these areas for at least twenty years.<p>The meanings of elder residents hinge on their memories of growing up and making a living when younger. Their meanings also resonate with the ideas and perspectives that these individuals have formed regarding the changes in their cultural landscape. Changes include those to agriculture; service provision; and the formation of the Grasslands National Park for which Val Marie is the gateway community and Redberry Lake Biosphere Reserve in which Hafford is located. <p>The broad themes of connections, separation, and continuity that I distilled in the narratives of elder residents have guided the identification of the meanings. To this end, the cultural landscape concept has provided an ideal framework. Including the different and diverse meanings of elder residents is integral to our conception of the cultural landscape as a whole, a characteristic that assists in guiding change and development in these communities. <p>In particular, elder residents contribute to an ethical landscape infused with meanings engendered by sentiments of connections, separation, and continuity and ones that hearken to their ethics. Such meanings can have a substantive impact on the decisions influencing these areas. Furthermore, as part of intangible cultural heritage, elder residents offer the meanings they have forged as well as their ethics, the ongoing result of having lived and worked in their cultural landscape. <p>This research has helped to bring relief to the meanings of elder residents in Hafford and Val Marie. Such meanings are necessary in the overall identity of the cultural landscape. The meanings that elder residents derive from their cultural landscape are a valuable asset for communities seeking to maintain their social and economic viability and sustainability.

<p>Marine protected areas (MPAs) are an increasingly prevalent and popular conservation tool, yet there is still much debate over whether they should emphasize the role of expert knowledge or local participation. This debate occurs among an international network of scientists and conservation professionals as well as in relation to particular places and MPAs. This dissertation contributes to an understanding of MPAs by addressing three questions: (1) How do differently situated actors within the MPA social network define and mobilize ideas of knowledge and participation? (2) How are knowledge and participation enacted and perceived in particular MPAs? (3) How do perceptions of knowledge and participation relate to actors' views of the success of MPAs? In order to address these questions, this dissertation presents the results of two separate projects: (1) a survey of international experts at the First International Marine Protected Areas Congress; and (2) an ethnographic study of two marine protected areas and their associated communities and social networks in southern Belize. The results of the survey indicate that the international MPA community is divided in their opinions on what constitutes science and what role scientists should play in the MPA policy process. Scientists who had a positivist view of science were reluctant to engage in MPA policy making, whereas government representatives who held positivist beliefs were more likely to support scientists advocating for particular MPA policies. The results of the ethnographic study in Belize illustrate that multiple groups work to produce, interpret, and contest knowledge for MPA policy, while also engaging in scalar strategies to define what MPAs are, how they should function, and who should be involved in their management. MPA success in Belize is not dependent on either conclusive expert knowledge or positive perceptions of participation, but rather on the accommodation of multiple groups' agendas.</p> / Dissertation

<p>This dissertation consists of four chapters. The first three chapters examine protected areas (or parks) from multiple perspectives. Parks are the first, and often only, line of defense in efforts to conserve biodiversity. Understanding of their promise and problems is necessary to achieve conservation outcomes. Chapter One determines vegetation patterns in and around parks of differing management categories across the Amazon, Congo, South American Atlantic Coast, and West African forests. Within these forests, protected areas are the principle defense against forest loss and species extinctions. In the Amazon and Congo, parks are generally large and retain high levels of forest cover, as do their surroundings. In contrast, parks in the Atlantic Coast forest and West Africa show sharp boundaries in forest cover at their edges. This effective protection of forest cover is partially offset by their very small size: little area is deep inside park boundaries. Compared to West Africa, areas outside parks in the Atlantic Coast forest are unusually fragmented. </p><p>Chapter Two addresses a human dimension of protected areas. Given certain characteristics, parks areas may either attract or repel human settlement. Disproportionate increases in population growth near park boundaries may threaten their ability to conserve biodiversity. Using decadal population datasets, we analyze population growth across 45 countries and 304 parks. We find no evidence for population growth near parks to be greater than growth of rural areas in the same country. Furthermore, we argue that what growth does occur near parks likely results from a general expansion of nearby population centers. Parks may experience unusual population pressures near their edges; indeed, individual case studies provide examples. There is no evidence, however, of a general pattern of disproportionate population growth near their boundaries.</p><p>Chapter Three provides a review of common approaches to evaluating protection's impact on deforestation, identifies three hurdles to empirical evaluation, and notes that matching techniques from economic impact evaluation address those hurdles. The central hurdle derives from the fact that protected areas are distributed non-randomly across landscapes. Matching controls for landscape characteristics when inferring the impact of protection. Applications of matching have revealed considerably lower impact estimates of forest protection than produced by other methods. These results indicate the importance of variation across locations in how much impact protection could possibly have on rates of deforestation.</p><p>Chapter Four departs from the focus of protected areas and instead addresses a more theoretical aspect of community ecology. Ecological theories suggest that food webs might consist of groups of species forming blocks, compartments or guilds. Chapter Four considers ecological networks (subsets of complete food webs) involving species at adjacent trophic levels. Reciprocal specializations occur when (say) a pollinator (or group of pollinators) specializes on a particular flower species (or group of such species) and vice versa. We characterize the level of reciprocal specialization for various classes of networks. Our analyses include both antagonistic interactions (particularly parasitoids and their hosts), and mutualistic ones (such as insects and the flowers that they pollinate). We also examine whether trophic patterns might be palimpsests. That is, there might be reciprocal specialization within taxonomically related species within a network, but these might be obscured when these relationships are combined. Reciprocal specializations are rare in all these systems even when tested using the most conservative null model.</p> / Dissertation

With the rapid development of the coastal environment and advances in fishing technology, marine biodiversity and fishery resources are decreasing dramatically. Therefore, each state is now focusing on conserving the marine environment. Planning Marine Protected Areas is one of the simplest and most efficient ways to do this. In recent years, researches have been conducted on Marine Protected Areas around the world. The government and academic fields in Taiwan also has started to value its surrounding marine environment. However, literature on the Marine Protected Areas in Taiwan has focused on policy and management, not so much on planning and zoning strategies. Therefore, this study uses the Geographic Information System (GIS) to simulate the planning and zoning process. This research set principles and zoning framework for Marine Protected Areas in Taiwan based on case studies and spatial analysis techniques. This study uses Gueishan Island in Yilan County as case study since the unique geographical environment of Gueishan Island provides potentiality to set Marine Protected Areas. In this study, it is suggested that "hot spring resources", "cetacean resources", and "fisheries resources" are the main protected objectives. The zoning strategies, management guidelines and recommendations are provided in this study based on these three protected objectives. According to the GIS simulation process, using the spatial analysis techniques is one of the possible efficient methodologies to plan and zone the Marine Protected Areas. With supplementary data and information, the results can be discussed more specifically in the further study. In addition, techniques of visualization during the MPAs zoning process can be a easier way for various stakeholders to understand, and to strengthen mutual communication, thereby reducing disputes to create successful Marine Protected Areas.

The protection and biodiversity of marine ecosystem become major concerns in the world. Taiwan is also increasingly interested in the establishment of marine protected areas, but it still lack of the scheme on ¡§how to perceive the process for the protected areas¡¨. The establishment of a protected area is all by the top down without a full planning for a proper managed mechanism, evaluation and assessment to the site. The lack of the funds from the government often causes the failure of monitoring and restoration to the protected site. These problems have caused unprovent from imappropiate management to the established protected areas or have made the protected site as a paper park by the administration. This study searches the literatures with regards to the planning processes and the site selection process of marine protected areas in Canada and Australia. The objective of the present study is initiated to determine and survey the problems of marine protected area (MPA) planning in Taiwan. The select sites for the present studies are the proposed MPA site ¡§Four Southern Island¡¨ and other established MPA sites in Penhu. The approaches for assessing the sites include the geographic information system (GIS) spatial analysis method for the aquatic resources and their distributions. Data collections consist of the funding sources for managing the MPA sites and the proposed planning for the delimitation of MPA at the shore areas. The biological information around the sites was assessable for the evaluation process in addition to the management scheme in the future requirement at the Four Southern Islands site. The current expanses supported by the Penhu county government and the Executive Yuan Coast Guard was used for comparing with the proposed budgets needed for the MPA sites. The results showed that the Four Southern Islands has not met with the requirements and guidelines as a MPA due to the lack of scientific survey on the distributions of aquatic species within the proposed 3 nm delimitation. A long-term research and monitoring of the resources shall be performed to evaluate the sites prior to be announced as a designate MPA site. Although local residents agreed positively about the important of MPA site establishment through the questionnaire and interviews, there is still the need to improve management practices and more strict law enforcement capacity to ensure the protection of the marine environment for achieving a sustainable development. The survey results have been made to the process of site selection of marine protected areas according to Canada, suggesting that the current planning of the Four Southern Islands in Penghu does not match the site selection process. There need to be clarified with the details of the implementation process. In the end, above finding may impact the establishment of protected areas, including the relationship between public sector¡¦s responsibilities, and socio-economic conditions of the surrounding area development, marine environment and resources and fishing activities and other aspects of the integration considerations. These are expected to be the important conditions for the recommendations for the MPA site selection and to ensure the sustainable development of marine environment.

This dissertation uses ¡§marine good governance¡¨ as the core to discuss the establishment of marine protected areas institutions in Taiwan. As a marine nation, it is a fatal key whether Taiwan can properly manage marine resources or not. Appropriately dealing with marine-related affairs can bring success to overall national development. The marine environmental diversity makes its affairs much more complicated than the land area. The global cognition of marine management has greatly changed. ¡§The concept of public management¡¨ has shifted from ¡§government¡¨ to ¡§governance¡¨. Good governance is the aim of public management nowadays. A marine nation should aim to have good marine governance. Establishing integrated marine institutions would be the key point. Although the quantity of Taiwan¡¦s marine protected areas has greatly increased, the effectiveness of management on marine protected areas is still called into question. This dissertation recommends that Taiwan should focus on integrating the institutions on marine protected areas. The future Marine Affair Organization and the corresponding marine governance legal structure would result in a ¡§Good Governance of a Marine Nation¡¨.

Overfishing of stock and decreasing biodiversity are grave concerns for the U.S. and the rest of the world. Understanding and applying spatial and temporal information of marine species’ reproductive ecology and critical life habitat is vital to the development of effective strategies for marine resource management. In the Caribbean, one of the critical science gaps hindering effective management is the lack of information on how environmental factors may make fish spawning aggregation (FSA) sites optimal for spawning. Understanding the patterns of seafloor characteristics of spawning aggregation sites is of great interest to managers who need a means to efficiently design marine protected areas to help rebuild regional fish stocks. The specific goals of the study were: (1) to map the seafloor at historically known grouper and snapper spawning aggregation sites in three different countries, and (2) to characterize quantitatively the geomorphology of the sites including horizontal and vertical curvature profiles of the reefs, bottom depth at spawning sites, distance between spawning sites and shelf-edges/reef promontory tips, and the shortest distance between the spawning sites and 100 m water depth. These data were field-collected with a GPS and single-beam eco-sounder that provided latitude/longitude and depth. The point data were interpolated to surfaces in GIS to determine slope, aspect, curvature, and distance from spawning sites and three-dimensional reef structures. This study revealed that all 12 known Nassau grouper spawning aggregation sites in Belize and 5 known sites in the Cayman Islands were located at convex-shaped seaward extending reefs (reef promontories) jutting into deep water, within 1 km of reef promontory tips. However, spawning aggregations did not always occur at the tips of reef promontories, though all were found along the shelf edges within 1 km of promontory tips. Sixteen sites were multi-species spawning sites. These general characteristics were used to predict an undiscovered multi-species spawning aggregation in Belize. A successful prediction in Belize, together with the compiled data from multiple sites indicate: 1) reef promontories are vital locations for transient reef fish spawning aggregations, and 2) this study provides a potential tool for prediction of unknown spawning sites in the Caribbean.

It is an internationally acknowledged that marine protected area (MPA) is an important measure for maintaining biodiversity and rescuing endangered species. MPA can also effectively inhibit human interferences such as development and pollution discharge. The establishment of MPA is possible to fulfill the goal of sustainable management, which is to conserve marine habitat for an integrative ecosystem and a higher biodiversity. However, how to design an effective MPA remains an important research issue to be explored. In order to grasp the spatial distribution of the ecological data in the study area, the current research uses spatial interpolation tool, Kriging, provided by the Geographic information system (GIS) software. Then three spatial analytical models have been developed based on integer programming techniques. It is guarantee that all three models can find the global optimal solutions for the best protective area partitions. This quantitative approach is more efficient and effective compared to the qualitative methods in many aspects. The models are able to preserve the maximum ecological resources under the limited spatial area. Besides, the model formulation can be adjusted from different environmental impact factors to fulfill the requirements of users. The case study of the research is to design a MPA for Kaomei wetland. However the spatial analytical models developed in this research can also be applied to protected area design in land area.

The aim of the present study was to investigate, firstly, whether the substitution of dietary starch by rumen-protected fat results in visible changes in the protein metabolism by increasing the urea flux and decreasing of AA levels in blood plasma as indicators for a change of AA oxidation, secondly, whether the fat-fed cows use predominantly long chain FA in the processes of milk fat synthesis or as an energy source in oxidation processes, and thirdly, whether the ratio of glucogenic to lipogenic nutrients could affect the supply of glucose in the metabolism of dairy cows. Two experiments were conducted. In either experiments, about 1.8 kg of starch in the ration of the control group were substituted by about 0.7 kg fat as protected fat (Ca salts of palm, soybean and sunflower oils in addition to protected soybeans) in the ration of the fat group. The first experiment was carried out on 32 multiparous high yielding dairy cows (16 Holstein-Friesian cows in each group) during the first 100 d of lactation. The second experiment was carried out in four periods in a cross-over design. Two cows were used in each period during the 6th to the 10th lactation weeks. The cows were infused intravenously with D-[U-13C6]-Glucose. The substitution of starch by protected fat tended to increase the milk production and milk lactose output and to decrease the microbial protein synthesis in the rumen and plasma glucose level. Also, the levels of ß-HBA and NEFA in plasma, the milk urea content and the total urea-flux were increased (P<0.05). Milk protein content but not yield and plasma levels of insulin, Met, Ser and His decreased (P<0.05) but the branched chain amino acids in plasma increased (P<0.05). The oxidation rate of FA was lower in comparison to other sub`strates. In the second experiment, the enrichment of milk fat and blood CO2 by 13C decreased but the recovery of 13C in milk lactose increased (P<0.065) due to high fat intake. The results indicate that the substitution of starch by protected fat can save glucose in the intermediary metabolism for lactose synthesis in the mammary gland and the cows used fatty acids predominantly for milk fat synthesis and not for oxidation.
