Nesta tese vou apresentar novos dados sobre padrões de ocupação dos Jê Meridionais e minhas interpretações sobre a história deste povo, com base em meu estudo de caso, do Alto Rio Canoas, região de Urubici, em Santa Catarina, Brasil. No planalto, os camposde altitude e a mata de araucária dominam a paisagem. Nas serrarias de Urubici, as nascentes de vários arroios e rios começam em zonas húmidas, com solos rasos e pedregosos, na área dos campos, a cerca de 1800m de altitude. Estas águas correm através de vales incisos florestados pela mata de araucária criando cachoeiras e corredeiras, que acabam por se transformar no meândrico Rio Canoas, que flui no meio de um vale largo e plano, em torno de 1000m acima do nível do mar. A montanhosa região de Urubici foi intensamente pesquisada na década de 60, mas depois disso, a pesquisa ficou estagnada. Os principais pontos deste projeto foram: Primeiro, foram revisadas e atualizadas as pesquisas anteriores, revisitando a maioria dos sítios arqueológicos mapeados na década de 60, atribuindo-lhes coordenadas geográficas, fotos e mapas, e descrições ambientais recentes. Segundo, além da visita aos sítios mapeados previamente, foi realizado um mapeamento oportunista de novos sítios, baseado em entrevistas com membros da comunidade local, o que gerou um novo mapa arqueológico da região. Terceiro, com base nessas informações e nas novas escavações em sítios específicos, iniciou-se a reflexão sobre as paisagens Jê do Sul, com o objetivo de compreender a história de longo prazo e o sistema de assentamento da tradição arqueológica Taquara-Itararé. Quarto, a partir das análises de grãos de amido de fitólitos, a partir de restos carbonizados de alimento aderidos a parede da cerâmica coletada na escavação do sítio Bonin, foram obtidos novos dados, importantíssimos para pensar novas formas de interpretação na arqueologia da tradição Taquara-Itararé. Tais análises trouxeram evidências de produção de alimentos como Zea mays, Cucurbitasp., Manihotsp., e o consumo alimentar de Phaseolussp. e Dioscoreasp. entre outros, o que, sem dúvida, é uma chave para pensar em outro tipo de organização social, mobilidade e economia para os povos proto-Jê Meridional. Em quinto lugar, no sentido de pensar uma \"estratigrafia paisagem do Jê Meridional\" um banco de dados SIG foi utilizado como uma ferramenta para criar modelos virtuais de, por exemplo, a análise visibilidade acumulada entre sítios e análise de rotas de menor custo. / In this thesis I will present new data on Southern Jêsettlement patterns, and my interpretations regarding the history of these people, based on my case study, from the Upper Canoas River, Urubici region, in Santa Catarina state, Brazil. On the highland plateau, the High Altitude Grasslands (or Campos) and the Paraná Pine Forest dominate the landscape. In the Urubici hills, various headwaters begin in wetland areas, with shallow and rocky soils, on Campos, around 1800m altitude. These waters flow through incised valleys forested by Paraná Pine and create waterfalls and rapids, which eventually turn into the meandering Canoas River that flows in the middle of a wide and flat valley, around 1000m above sea level. The mountainous Urubici region was intensively researched in the 60\'s, but after that, research wasstagnated. The main points of this project were: First, I reviewed and updated previous research, which involved relocating the sites mapped in the 60\'s, assigning them geographical coordinates, photos and maps, and improving environmental descriptions. Second, I carried out an inspection of previously recorded sites and carried out opportunistic survey, based on interviews with members of the local community, looking for new sites, and making a new archaeological map of the region. Third, based on this information and my new excavations at targeted sites, I aimed to think about the Southern Jê landscapes, with a view to understanding the long-term history and the settlement pattern of the Taquara-Itararé archaeological tradition. Fourth, starch grain and phytoliths analysis from charred food remains founded in pottery, collected at Bonin site excavation, achieved important new data for new interpretive ways on Taquara-Itararé archaeology, bringing to us food production evidences of Zea mays, Cucurbitasp., Manihotsp., and food consumption of Phaseolussp.,Dioscoreasp. and others, what is a key to think another kind of social organization, mobility and economy for southern proto-Jê people. Fifth, in a way to think the \"southern Jê landscape stratigraphy\" aGIS database were used like a tool to create virtual models of, for example, cumulative viewshed analysis and least coast pathway analysis.

The utility of dental calculus as a proxy for diet and mouth use is explored for the Middle Holocene Cis-Baikal region of Central Siberia based on two methods: a macroscopic analysis of severity and a microscopic analysis of particles within deposits. The study area was inhabited by two culturally and biologically distinct cultures, the Early Neolithic (EN) Kitoi culture (8,000 to 7,000/6,800 cal B.P.) and the Late Neolithic-Early Bronze Age (LN-EBA) Isakovo-Serovo-Glaskovo (ISG) cultural complex (6,000/5,800 to 4,000 cal B.P.), separated by a period of cultural transition marked by a cessation in formal cemetery use. Data were collected from four cemetery sites, two dating to the EN and two dating to the LN-EBA. Nonparametric testing of calculus severity revealed that, for adult males and juveniles, lakeshore populations displayed greater affinity to each other than to their contemporaneous cultural counterpart populations living along riverine systems in the Angara River Valley. Trends within the EN cemetery Shamanka II contrasted to the other cemetery populations, with noticeably larger deposits in anterior quadrants and significant sexual distinctions. The proportion of protein to carbohydrates consumed is known to influence calculus formation, but both cultural groups lived on a diet based predominately on meat sources so dietary ratios alone do not adequately explain the differences distinguished. A complex multifactorial model involving microregional differences in resources/environment, foraging patterns, individual variation, and dental wear patterns provides at least a partial explanation for the results observed. A wide range of particles were recovered during the microscopic analysis of calculus, albeit in low concentrations. The low starch grain counts were consistent with a diet based predominately on meats but still provide some of the first direct evidence for plant consumption in the Cis-Baikal, including possible plant processing by cooking or grinding based on damage evident on the grains. Other particles recovered may provide evidence of mouth use activities or palaeoenvironmental influences. Together, the two components of this analysis offer strong evidence that dental calculus is a useful tool for reconstructing hunter-gatherer lifeways but also highlight the limitations of conducting this type of research on previously excavated and potentially contaminated material.

Forest stands may act as important carbon storage places - sinks, due to carbon allocation into both the plant biomass in the process of photosynthesis and the soil. Enhancement of CO2 concentration affects a whole range of plant physiological processes and, thus, it is necessary to study its effect on photosynthetic apparatus - leaf anatomical structure and chloroplast ultrastructure. The first aim of the Thesis was to evaluate changes in chloroplast ultrastructure of common beech (Fagus sylvatica L.) under the effects of both elevated CO2 concentration and different irradiance. The second aim was to evaluate if the anatomical parameters obtained from the middle part of the leaf are representative for the whole leaf blade. The trees were grown in glass domes at the Bílý Kříž experimental site in the Beskids Mountains (Czech Republic), owned by the CzechGlobe Institute. Leaves were sampled in 2010 from juvenile trees, which were planted in 2005 being 5-year old and cultivated since then in ambient (AC; 390 micromol/mol) and elevated (EC; 700 micromol/mol) CO2 concentrations. The EC effect was recorded to be an increased proportion of starch grains in the chloroplast median section and decreased proportion of of intergranal thylakoids (IGT) while the ratio of granal to intergranal thylakoids...
