This study examines how travelogues by the Russian author Anton Chekhov, an American, George Kennan and a British citizen, Harry de Windt, contributed towards establishing the image of Siberia towards the end of the 19th century, juxtaposing their individual views against the commonly perceived view of the region at the time. In examining the texts, a literary analysis is merged with elements of other approaches, through a strong thematic focus, centring on the cultural and ideological assumptions implied in the texts. The findings reveal that both native inhabitants and foreigners are capable of expressing a justifiable opinion on a locality, resulting in different versions of what is observed, from divergent points of view. Although the three writers in this study appear to support a negative view of Siberia, closer investigation show evidence of optimism about the eventual destiny of a region in a stage of transition. / Linguistics and Modern Languages / M.A. (Russian)

The evolution of metabolism regulation is an intertwined process, where different strategies are constantly being developed towards a cognitive ability to perceive and respond to an environment. Organisms depend on an orchestration of a complex set of chemical reactions: maintaining homeostasis with a changing environment, while simultaneously sending material and energetic resources to where they are needed. The success of an organism requires efficient metabolic regulation, highlighting the connection between evolution, population dynamics and the underlying biochemistry. In this work, I represent organisms as coupled information-processing networks, that is, gene-regulatory networks receiving signals from the environment and acting on chemical reactions, eventually affecting material flows. I discuss the mechanisms through which metabolism control is improved during evolution and how the nonlinearities of competition influence this solution-searching process. The propagation of the populations through the resulting landscapes generally point to the role of the rhythm of cell division as an essential phenotypic feature driving evolution. Subsequently, as it naturally follows, different representations of organisms as oscillators are constructed to indicate more precisely how the interplay between competition, maturation timing and cell-division synchronisation affects the expected evolutionary outcomes, not always leading to the \"survival of the fastest\".

Master of Landscape Architecture / Department of Landscape Architecture/Regional and Community Planning / Hyung Jin Kim / A significant decline of mental and physical health exists within college students today (ACHA, 2014; Gallagher, 2006). Recently, to promote mental health, restorative landscapes have emerged as a trend in healthcare environments by formalizing the healing properties of nature within a designed environment. Humans have been shown to undergo a measurable relief of stress, improved attention, and an improved overall sense of well-being when exposed to a restorative landscape setting. Opportunities exist for university campuses to more advantageously employ the mental health benefits of restorative landscapes. Furthermore, to address physical health, the university campus holds unique opportunities to increase students’ physical activity through promotion of active lifestyles using active modes of transportation. Campus streets, based on their lack of affordances to promote mental and physical health as well as their inherent connectivity to key campus buildings and spaces are investigated as a site for a designed solution. A recent trend of campus street conversions to pedestrian malls is identified and explored as a tool to facilitate creation of a restorative and active campus. The project, based in two fundamental research questions, investigates how campus street design can improve the collective mental health of college students, and how campus street design can promote physical health. Literature review analysis reveals theories and principles of restorative landscape and campus design. The project unites these findings with case study analysis to form a framework to facilitate the design of restorative environments within a university campus. Pragmatic evidence of built environment interventions has been synthesized from literature review and case study analysis into an additional framework to increase physical activity through active transportation. Kansas State University’s campus has been identified as a suitable case for a design proposal. Planning and design decisions at three nested scales are made to illustrate how the frameworks may be applied to reclaim a campus street as an active and restorative “garden street.” In the context of declining mental and physical health among college students, the synthesis of principles related to restorative landscape design and active transportation presents a valuable structure to mitigate declining mental and physical health of students.

The major goal is to reveal the need to understand the dynamics and impacts of landscape change from a current temporal perspective. This is performed here through the study of various settings in the landscape along Highways 180 and 64/180 in Arizona, being proposed for State Scenic Road designation. Selected landscape segments is the subject and the highways are a flexible platform from which to observe and assess these landscapes. Once sources, kinds of, and magnitude of possible or potential landscape changes and impacts are identified, this study proceeds to prescribe landscape planning strategies for their scenic and open space protection and enhancement. Potential landscape change and its impact should be predicted in order to plan and manage for the protection and enhancement of desired landscape values into the future. It can input people's perceptions to appreciate landscape values from varied perspectives such as: aesthetic, ecological, cultural, and socioeconomic.

Understanding the impacts of land-use change on biodiversity and the ecosystem services that it provides is of great importance given unprecedented growth of the human population. Past studies attempting to explore these impacts have described the overall structure of communities (i.e. species richness and trait diversity) across gradients of local scale degradation and fragmentation, and have sought to identify whether the loss of species following land-use change is non-random. Yet, despite a wealth of research we still lack a generalised understanding of how land-use change impacts on traits responsible for determining species sensitivity and their role within ecosystems, particularly for vertebrates. Moreover, despite the importance of niche-based processes in the assembly of communities, we have not yet elucidated whether these are important in mediating the collapse of communities in human-dominated landscapes. To fill these existing research gaps, I collated comprehensive avian species inventories from fragmented and degraded forests and compared their structure with communities existing in continuous forests. In Chapter 2, I tested whether sensitivity of species to forest fragmentation varies between the temperate zone and the tropics and whether there are key differences in the size of fragments required to maintain ecosystem processes in these regions. I found that sensitivity to fragmentation varies according to functional group and body mass, with the prevalence of insectivores and large frugivores declining in relation to fragment size, particularly in tropical fragments smaller than 100 ha. In Chapter 3, I tested whether functional diversity and the mean position of trait diversity of insectivores and frugivores, changed across a gradient of intensifying land-use change. I found a decline in the functional diversity of forest species and a shift in the mean community traits for both forest and non-forest species. In Chapter 4, I tested whether the structure of tropical bird communities are influenced by species interactions in a fragmented landscape. I found increasing over-dispersion in functional and phylogenetic trait relatedness among species with decreasing fragment size, suggesting that competitive interactions are important in the disassembly of avian communities. In Chapter 5, I modelled the impact of forest cover change on ecosystem function across the Brazilian Amazon, focusing on seed dispersal by birds. Furthermore, I tested whether ecosystem function declined linearly with decreased forest cover after accounting for differences in the underlying pools of species. I found the lowest levels of functional diversity along the southern arc of deforestation and that the dispersal of large seeds showed some resilience to declining forest cover. Taken together, my results suggest that the loss of species from communities in degraded and fragmented landscapes is strongly non-random. Insectivores and large frugivores are most sensitive to land-use change, with species located in the densest parts of trait space being most threatened by a decline in forest patch size, suggesting that species interactions regulate the collapse of avian diversity in human-modified forests. I conclude that land-use change has important implications for the provisioning of ecosystem services, including seed dispersal and the control of insect herbivores. The impact of future land-use change is likely to be mediated by the composition of the original pool of species and the amount of redundancy in the ecosystem services that they provide. I discuss the relevance of my findings to land-use management strategies and policy interventions, and in particular conclude that these should, where possible, maintain pristine forest patches above 1000 ha, improve connectivity among habitat patches, and ensure greater protection for logged and burnt forests. Future studies should focus on clarifying the link between shifts in vertebrate community structure and the functioning of forest ecosystems.

DTM Improvement in Sandstone Cliffs Relief using precise Co-registration of Airborne Laser Scanning Data Abstract The topic of this thesis is to design innovation of methodology improvement of digital terrain models from airborne laser scanning data in sandstone rocks rugged relief. Theoretical part of this thesis presents the Project GeNeSiS and New Elevation Model Project of the Czech Republic Territory, in which the test datasets were acquired. Simultaneously this section describes in detail methods of co-registrations datasets from strip adjustment to 3D least squares matching method, which have been published until now. In practical part of the work the Pravčická brána model region is introduced firstly. The focus of this section lays on description of new methodology for co-registration and classification of point clouds using spatial query. Co-registration of point clouds, respective detection transform parameters in this thesis is solved by introducing ground control areas. For each such region displacement and rotations in each axis are detected which subsequently determines the global transformation key. Innovation of the thesis lies in the fact that for DTM improvement there is sufficient only one point cloud. The second (and possibly others) point cloud is classified by presented algorithm...

In the territory of the Gwich’in First Nation, in Canada’s Northwest Territories, environmental, sociocultural, and economic changes are affecting relationships between communities and the land and water. In this thesis, I used two research projects to explore the impacts of social-ecological change in Gwich’in territory by examining cumulative impacts in the cultural landscape, and determinants of access to fish and well-being. In the first part of my MA, I used spatial overlay analysis to quantify and map: 1) cultural feature intensity, 2) cumulative environmental disturbance, and 3) overlap between disturbances and cultural features. I also interviewed four regional cultural heritage experts, who contributed critical insights into representing Gwich’in cultural features. The first two analyses indicated that overlay methods can facilitate understandings of land use and cumulative impacts, illustrating Gwich’in territory as a cultural landscape encompassing widespread, dense cultural features and diffuse, lower intensity cumulative environmental impacts. The third analysis showed that overlaying cultural feature and disturbance data is a novel, straightforward step to better incorporating cultural impacts in cumulative impact assessments. Many of the changes I mapped are affecting fishing practices central to Gwich’in livelihoods. To better understand these changes, in the second part of my MA I explored the relationship between drivers of access to fish and well-being amidst social-ecological change, by interviewing 29 Gwich’in individuals. My interviews showed that socioeconomic and environmental barriers have decreased access to fish. However, access to fish remains critical and related to well-being, driven by various socioeconomic factors. Many of these factors are reflected in sharing networks and adaptive practices that are encompassed in ecological monitoring and land-based education. These factors may strengthen Gwich’in fishing livelihoods, and highlight the importance of programs like the Rat River Char Monitoring program, and land-based education like the Ganahghootr’onatan – Teetł’it Land Based Learning Project. / Graduate

Fecal samples were obtained from guenons in Gombe National Park utilizing noninvasive, opportunistic sampling techniques. Samples were then examined for the presence of gastrointestinal parasites using chlorazol black stain, Lugol’s iodine staining, as well as concentration via fecal flotation with Sheather’s sugar solution. Results were analyzed using SPSS (IBM corp), and compared to other forested regions in Africa to determine whether hybridization influences parasite prevalence of these guenons living in Gombe; and if these guenons differ from similar guenons in other regions of Africa. The null hypothesis was unable to be rejected in all cases; hybridization could not be stated as a contributing factor for differences found in parasitic prevalence rates. Furthermore, no statistical difference was found between Gombe’s guenons, and those living in other regions of Africa in most cases. The author suspects that the abundance of parasitic generalists discovered, small sample size, and opportunistic sampling protocol contribute to these finding. / Includes bibliography. / Thesis (M.A.)--Florida Atlantic University, 2017. / FAU Electronic Theses and Dissertations Collection

Mesmo com o crescimento da dependência da vida humana em relação aos serviços ecossistêmicos, a taxa de perda de diversidade genética no planeta tem alcançado níveis semelhantes à de grandes eventos de extinção, evidenciando a necessidade de ações para a conservação dos recursos naturais. Em adição aos tradicionais instrumentos de comando e controle para a conservação, os instrumentos econômicos têm tido crescente atenção no mundo nos últimos anos, com especial destaque para os Pagamentos por Serviços Ambientais (PSA). A abordagem de pagamentos de incentivos tem crescido na última década e, apesar das potencialidades que o PSA apresenta, muitos programas falham em incorporar o conhecimento científico em sua execução, sendo esse um dos aspectos que podem acarretar baixo desempenho ambiental e econômico. Neste contexto, o presente projeto buscou avaliar a custo-eficácia do PSA em paisagens fragmentadas. A área de estudo é o estado de São Paulo, cuja fragmentação historicamente ocorre pela expansão agropecuária e pelos diversos impactos decorrentes do grande crescimento populacional em seu território. Foram distribuídos questionários para a obtenção das preferências dos proprietários rurais paulistas em relação aos programas de PSA para restauração de vegetação nativa. Os dados coletados foram relacionados a características socioeconômicas e ambientais e um modelo beta inflacionado de zero misto dentro da classe GAMLSS foi utilizado. Em seguida, o modelo foi utilizado para predizer os resultados para os proprietários não entrevistados e a curva de investimento para diferentes retornos para conservação foi construída. Os resultados apontaram que o PSA é uma alternativa muito custosa frente aos orçamentos ambientais paulistas e que traz poucos benefícios para a restauração no estado de São Paulo. A pesquisa possui uma vertente teórica, pois contribui para a compreensão da adequabilidade do PSA em paisagens fragmentadas, e uma vertente prática, pois explicita a quantidade de recursos necessária para a execução dos programas analisados. / Although the dependence of human activities on ecosystem services has risen in the past decades, the current rate of genetic diversity loss has substantially declined and reached alarming levels. In addition to the traditional command and control approach for the promotion of conservation, growing attention has been given to economic instruments, especially to Payments for Environmental Services (PES). Despite all potentialities of the PES instrument, many programs fail to introduce scientic knowledge in the execution. Such a lack of foundation may result in low environmental and economic performance. The present research aims at evaluating the cost-effectiveness of PES in fragmented landscapes. The study area is the state of São Paulo, which has been fragmented by the agricultural and pasture expansion, and the impacts linked to the large population growth. A survey with dierent PES programs was sent to rural landowners and responses were analyzed and linked to socioeconomic and environmental characteristics through a zero-inflated beta mixed model, within the GAMLSS framework. The model was used to predict enrollment of non-respondents in different PES programs. Finally, the relationship between total area for restoration and the amount of resources needed for each program was compared to the environmental budget of the state of São Paulo. Results show that PES is a very costly alternative that can provide only few results for restoration. The present work has a theoretical orientation, as it contributes to the comprehension of the feasibility of PES programs in fragmented landscapes, and a practical orientation, as it quantifies the amount of resources required by the programs analyzed.

Esta tese trata da pesquisa arqueológica realizada na Terra Indígena (T.I.) Koatinemo, junto ao povo Asurini do Xingu. A partir dessa experiência reflete-se sobre a temporalidade das paisagens e as histórias indígenas de longa duração da região do médio-baixo Xingu, combinando-se dois horizontes de reflexão: o primeiro, lida com paisagens persistentes entrelaçadas à experiência da vivência nos lugares, ao contato com as narrativas históricas e à tradição oral dos Asurini; e o segundo, interligado ao primeiro, lida com a paisagem artefatual, materialmente transformada ao longo do tempo, e constituída por marcas visíveis deixadas pelas diferentes atividades humanas do passado. Em termos metodológicos foram empregadas técnicas de survey arqueológico e análise de coleções cerâmicas provenientes dos lugares/sítios arqueológicos identificados na referida T.I. Ao final o texto apresenta uma contribuição para o conhecimento sobre a ancestralidade indígena da paisagem e o modo como esta se relaciona com a história dos Asurini e das populações de línguas Juruna e Karib no médio-baixo Xingu. / This thesis deals with the archaeological research carried out in the indigenous land Koatinemo, together with the Asurini do Xingu indigenous people. From this experience, a reflection on the temporality of the landscapes and on the long lasting indigenous stories of the mid-low Xingu region was performed. Two horizons of reflection were combined on the approach. The first one deals with persistent places interconnected with the experience of living in the places, the contact with the historical narratives and the Asurini\'s oral tradition. The second one concerns the artifactual landscape that has been materially transformed over the time and consists of visible marks left by different human activities throughout the time. In methodological terms, the study applies techniques of archaeological survey and analysis of ceramic collections from the identified archaeological sites in the referred indigenous land. At the end, the text presents a contribution on current knowledge about the indigenous ancestry of the landscape and the way it is related to the history of the Asurini and of the populations of Juruna and Karib languages from the mid-low Xingu.
