Made available in DSpace on 2015-03-13T17:08:17Z (GMT). No. of bitstreams: 1 EduardoVQ.pdf: 3502040 bytes, checksum: cedac0b69deb4f4ec6d96c08f23f3160 (MD5) Previous issue date: 2008-12-15 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior / The study carried out in the environment of Maracaja? reef an S?o Roque channel, had as main objective to analyze the characteristics of sediments active locally expressed in the grains, through collections of sediments in the field, technical processing and data analyzes of sediments. Data processing were made on three main aspects: biotic composition, concentration of calcium carbonate and particle size of the sediment. Differences between the sediments of the reefs and channel were observed. It was emphasized the contribution of algae limestone in the production of carbonate, with some influence of foraminifera near the coast. The particle size distribution presented significant results for the understanding of locally sedimentary deposits. The results showed an environment of carbonate, with predominance of algae limestone, associated to unconsolidated sediments with gross granularity, besides the presence of rhodoliths in all samples.The fragmentation of biotic components and the prevalence of elliptical rhodoliths with little or no branch, indicate an environment of high energy hydrodynamics. This work is a further contribution to the understanding of sedimentology active locally in reef environments, in particular the of Maracaja? reef, by virtue of their complex ecosystem composed of a diversity of wild fauna and flora that still little studied in Brazil comparing to accelerated growth of teeth extractions and usufructs of natural resources causing often irreversible impacts to the environment / O estudo realizado teve como principal objetivo analisar as caracter?sticas dos sedimentos superficiais de fundo, atuantes localmente, no complexo recifal de Maracaja? e no canal de S?o R?que, sob diferentes aspectos: composi??o biog?nica, concentra??o de carbonato de c?lcio e granulometria do sedimento. Os resultados apresentaram as varia??es no sedimento superf?cial do fundo marinho quanto ? Biof?cies, An?lise Granulom?trica, Classifica??o Faciol?gica e Classifica??o de Rod?litos. Observou-se claramente diferentes padr?es sedimentol?gicos existentes nos recifes e no canal localizado entre os recifes e a costa, refletido em todos os par?metros levantados, revelando um ambiente carbon?tico, com predom?nio de algas calc?rias, associadas a um substrato inconsolidado com granula??o grossa. Enfatiza-se a contribui??o das algas calc?rias na produ??o de sedimentos carbon?ticos, com alguma influ?ncia de foramin?feros pr?ximos ? costa. A distribui??o granulom?trica apresentou resultados importantes na classifica??o dos sedimentos. Os sedimentos de tamanho m?dio se restringiram no canal numa ?rea protegida pelos recifes, enquanto que o sedimento com granula??o grossa se distribuiu no restante da ?rea, cobrindo parte da crista e toda regi?o frontal do recife, al?m de uma regi?o mais ao sul do canal. Rod?litos el?pticos se distribuiram em quase toda ?rea, excluindo apenas uma regi?o ao sul do canal e protegido pelos recifes com predom?nio de rod?litos discoidais. O predom?nio de rod?litos el?pticos com pouca ou nenhuma ramifica??o permite inferir um ambiente de alta energia hidrodin?mica, e a presen?a de rod?litos discoidais exclusivamente nos pontos ao norte do canal de S?o Roque e protegidos pelos Recifes possivelmente delimita uma ?rea de menor hidrodin?mica. O presente trabalho constitui mais uma contribui??o para o entendimento das caracter?sticas sedimentol?gicas atuantes localmente nos ambientes recifais, em especial os Parrachos de Maracaja?, em virtude de seu complexo ecossistema composto por uma diversidade de fauna e flora, ainda pouco estudadas no Brasil, contrapondo ao crescimento acelerado de extra??es e usufrutos dos recursos naturais causando impactos muitas vezes irrevers?veis ao meio ambiente

A indústria lítica do sambaqui Mar Casado, litoral do estado de São Paulo / The lithic industry of the Mar Casado shell mound, costal of the São Paulo State

Daniela Maria Alves 14 February 2011 (has links)
A pesquisa aqui apresentada trata do estudo da cultura material lítica do sambaqui Mar Casado. Este sambaqui situava-se na cidade de Guarujá, estado de São Paulo. O sambaqui Mar Casado foi pesquisado entre os anos de 1961 e 1962 e juntamente com outros sítios litorâneos paulistas, pesquisados no mesmo período, faz parte da história da Arqueologia brasileira. Este trabalho desenvolveu-se de modo a melhor compreender as pesquisas empreendidas em um contexto arqueológico diferente do vivido atualmente, além de revalorizar antigos acervos conservados no museu. A cultura material lítica encontrada nos sambaquis brasileiros é bastante diversificada e apresenta suas especificidades. Os artefatos brutos e polidos, particularmente, receberam pouca atenção no decorrer da pesquisa arqueológica. Este estudo pretendeu analisar os artefatos líticos por meio da abordagem tecnológica, buscando observar as marcas de uso deixadas nos artefatos. A análise demonstrou que a população de Mar Casado encontrou um modo eficaz de administrar o uso de seus objetos líticos: usando várias superfícies do mesmo artefato para diversos fins. Isto significa dizer que esses artefatos tinham como característica a multifuncionalidade. Os sambaquieiros de Mar Casado provavelmente fizeram uso desses artefatos para processar vegetais, grãos, sementes e outros alimentos, além de usá-los para triturar pigmentos ou ainda como abrasivos em materiais como osso, madeira, concha. / The research presented here deals with the study of lithic material culture of the shell mound Mar Casado. This shell mound was located in the city of Guarujá, São Paulo. The shell mound was searched between the years 1961 to 1962 and along with other coastal sites in São Paulo surveyed in the same period, part of the history of Brazilian Archaeology. This work was developed in order to better understand the archaeological research undertaken in a context different from that experienced today, and upgrade old preserved in museum collections. The lithic material culture found in shell mounds in Brazil is very diverse and has its specificities. The rough and polished artifacts, particularly, have received little attention in the course of archaeological research. This study sought to examine the lithic artifacts through technological approach, seeking to observe the use-wear of artifacts. The analysis showed that the population of Mar Casado found an effective way to manage the use of their lithic objects, using various surfaces of the same artifact for various purposes. This means that these artifacts had the characteristic of multifunctionality. The population of Mar Casado probably did use these artifacts to process vegetables, grains, seeds and other foods, and use them for grinding pigments or abrasive materials such as bone, wood, shell.

Pottery Exchange and Interaction at the Crystal River Site (8CI1), Florida

Kemp, Kassie Christine 29 October 2015 (has links)
The Crystal River site (8CI1) is a Woodland-period mound (ca. 1000 BC to AD 1050) complex located on the west-central Gulf coast of Florida. Links to the Hopewell Interaction Sphere suggest that the people of Crystal River had connections with a broad range of communities, yet little is known concerning the role the site played in local, regional, or long-distance exchange networks. Pottery traditions vary amongst different communities of practice, therefore the level of interaction at Crystal River can be measured by looking at variation in the ceramic assemblage. I combine type/attribute, vessel form and function, gross paste, and chemical analyses to determine the amount of variability present in the pottery assemblage. These analyses show that Crystal River has a high level of ceramic variation with some spatial and temporal patterning. To determine Crystal River’s membership in and potential role within a sphere of interaction, I compare these patterns to three community types with diverse social interfaces. This research suggests that Crystal River may have started out as a homogenous, residential community but through time began to interact with a number of diverse, regionally associated communities drawn to the site for special occasions.

Lasting Legacies of Hurricane, Harvesting, and Salvage Logging Disturbance on Succession and Structural Development in an Old-Growth Tsuga canadensis-Pinus strobus Forest

Sass, Emma 01 January 2017 (has links)
Disturbance events affect forest composition and structure across a range of spatial and temporal scales, and forest development may differ after natural, anthropogenic, or compound disturbances. Following large, natural disturbances, salvage logging is a common yet controversial management practice around the globe. While the short-term impacts of salvage logging have been studied in many systems, the long-term effects remain unclear. Further, while natural disturbances create many persistent and unique microsite conditions, little is known about the long-term influence of microsites on forest development. We capitalized on over eighty years of data on stand development following the 1938 hurricane in New England to provide the longest known evaluation of salvage logging impacts, as well as to highlight developmental trajectories for eastern hemlock (Tsuga canadensis)-white pine (Pinus strobus) forests under a variety of disturbance histories. Eight decades following disturbance, there were no differences in current overstory composition between areas that were logged, hurricane disturbed, or hurricane disturbed and salvage logged, but white pine declined across most sites. In contrast, structural characteristics remain distinct between the three management histories. In the unsalvaged area, the diversity of microsites and the coverage of uprootings and pits influenced overstory tree composition, diversity, and structural characteristics. These findings underscore the long-term influence of salvage logging on forest development and the importance of natural disturbance-mediated microsite conditions on tree species growth and survival. Future salvage logging efforts should consider these impacts and provide a greater range of unsalvaged areas across the landscape to maintain these important structural legacies over the long term.

Optimizing Remote Sensing Methodology for Burial Mounds in the United States and United Kingdom

Corkum II, Alexander C. January 2019 (has links)
Within the archaeological record ‘mounds’ are often ubiquitous. They are common in many ancient cultures, and they vary in size, construction techniques and use. This research is focused upon optimizing the use of remote sensing for the non-invasive study of mounds both in the United States and the United Kingdom. This thesis presents three representative earthen mound sites and proposes a comprehensive and modular survey methodology to guide the planning and execution of a mound survey tailored to the unique requirements presented by the cultural resource at a particular location. In doing so, the research has provided optimized approaches to high resolution three-dimensional topographic models using a variety of digital methods. These models have been shown to accurately capture the variability of the modern ground surface, which is of vital importance to the management of the mounds. Furthermore, these models have proved vital for integrating geophysical methods into the holistic workspace, thereby providing a better archaeological understanding of the below ground remains. Every mound surveyed presented different challenges, and therefore had to be approached in a slightly different way. However, the general methodology was highly effective for both characterizing below-ground archaeological and natural anomalies, and for assessing the state of preservation of all mounds surveyed. As a result, a flowchart has been generated for non-invasive assessment of mounds in general. If followed, this will allow the production of a “snapshot” of the mound or mound group at a fixed point in time with the resolution necessary to produce useful and insightful interpretation. While this research focuses on the application of geophysical and topographic survey in the United Kingdom and United States to a mound or mound group, this methodology and the associated outcomes can be valuable more globally not only for archaeology, but also heritage management.

The Effects of Mechanical Site Preparation Treatment and Species Selection on Survival and Carbon Pools in 12-Year-Old American Sycamore (<i>Platanus occidentalis</i>) and Willow Oak (<i>Quercus phellos</i>) Riparian Plantations in the Southeastern U.S. Piedmont

Lynn, Drake Havelock 16 July 2024 (has links)
Riparian wetlands may provide numerous ecosystem services, including water quality protection, food and fiber supply, wildlife habitat, and carbon sequestration. In recent years, riparian forests have received increased attention and funding for riparian forest restoration projects. Unfortunately, failures of riparian restoration efforts are likely due to mortality of planted trees. Tree mortality is commonly attributable to several factors, including selection of species that are not well suited to the wetland sites, inadequate planting densities, soil compaction associated with former agricultural activities, lack of microtopographic relief that allow small seedling to survive on wet sites, competition by herbaceous plants, and browse. Selection of well-suited species, dense planting and use of mechanical soil site preparations are all potential remedies to partially address success of wetland restoration plantings. Riparian restoration projects have historically been undertaken with goals of improving water quality and/or wildlife habitat, but in recent years there has been increased valuation of carbon sequestration. Carbon valuation appears to be increasing, but more research is needed to determine rates and pools of carbon accumulation in riparian areas. Our research quantifies forest establishment effects on multiple carbon pools in a densely planted, 12-year-old old-field riparian restoration. Our research evaluated the effects of four soil mechanical site preparations (bed, disk, pit, and mound and rip) and species selection (American sycamore (Platanus occidentalis) and willow oak, (Quercus phellos) on forest establishment and carbon storage across multiple pools, namely in planted trees, herbaceous vegetation, fine roots, organic soil horizons, and the mineral soil. At 12 years, we found that species selection was more important to carbon storage than site preparation. American sycamore was well suited to the site and had better survival than willow oak (64% vs 42% survival). American sycamore also stored more carbon across all site preparations than willow oak. Measured carbon storage averaged 74.8 Mg ha-1 for American sycamore treatments and 63.1 Mg ha-1 for willow oak treatments. The plots were densely planted (1.2 m (4ft) by 1.8 m (6ft) spacing), and forests were established even in higher mortality willow oak plots. These results indicate that high planting density is potentially a viable practice for establishing riparian forest cover, especially if desired species are marginally site suited or other survival inhibiting factors exist. / Master of Science / Riparian forests located within the floodplain of streams are known to protect stream water quality, provide wildlife habitat, and store carbon. Due to these benefits, trees may be replanted on riparian areas that were formerly used for agriculture. Unfortunately, trees planted on these restoration sites have often died. The tree mortality may be due to planting incorrect tree species that may struggle on wet floodplains, soil compaction from agricultural practices, not enough trees being planted, and restored floodplains lacking small, elevated areas common across natural wetlands known to favor tree rooting and survival. Reasonably, selecting species that are well suited to a specific site, planting trees more densely, and using plowing methods designed to break up compaction and create some relief in elevation would amend these issues. Traditionally, floodplain restorations have focused on improving water quality and providing habitat for wildlife, but the benefits of storing carbon have become increasingly valuable in recent years. While we know that wetlands store carbon, research is needed to examine how quickly and where carbon is stored. Our research quantifies forest establishment and carbon storage of very densely planted, 12-year-old American sycamore (Platanus occidentalis) and willow oak (Quercus phellos) plantations. This research examines the effects four soil tillage methods and tree species selection had on tree survival and carbon storage. Carbon storage was measured in vegetation, soil, and small roots. Twelve years after planting, species selection had a greater impact on carbon storage than soil tillage methods. No tillage method altered survival or total carbon after 12 years, but American sycamore was found to have better survival and more carbon than willow oak in all soil tillage treatments. Both species were successful in establishing planted forests on the floodplain, but the success was aided by the very high initial numbers of planted trees that ensured enough trees would survive on the site even after trees were lost to mortality. Creation of willow oak forests benefitted more from dense planting, as it was less suited to the site and more planted willow oaks died. We recommend tillage for compacted soil, selecting the most suitable tree species, and planting adequate numbers of trees.
