It is important to study subglacial environments in northern Canada for many reasons, such as to develop a more comprehensive understanding of glacial landscape development and to aid in mineral exploration. The purpose of this research is improve understanding of the Quaternary Geology of north central Hall Peninsula, Baffin Island, the subglacial dynamics record in particular, in order to provide industry with new knowledge, maps and interpretations to aid in mineral exploration. The glacial history of north-central Hall Peninsula, Baffin Island is very complex. By studying the subglacial landscape using both remote- and field- based techniques it was possible to develop a subglacial landscape map and a flowset map which highlighted areas with different glacial histories and basal thermal regimes. The subglacial dynamics and how they changed spatially and temporally shaped the landscape to what it is today with a mixture of cold, intermediate, and warm-based ice. Through mapping using remote sensing and field methods, seven glacial landform and striation directions were found and grouped into four ice flow events. The identified ice flows include regional flows, northern and eastern fjord influenced areas, central deglacial flows, and modern icecap flows. Subglacial erosion was investigated using several proxies including streamlined hill elongation ratios, streamlined hill density, and bedrock controlled lake density studies. These proxies together with the subglacial landscape map were overlaid to select discrete zones, termed glacial terrain zones (GTZs), in an attempt to analyze the subglacial dynamics and how different basal thermal regimes interacted with the landscape. Five glacial terrain zones (GTZs) were identified, with different spatio-temporal basal ice regimes and landform assemblages. The first zone (GTZ 1) is characterized by an expansive flowset of parallel paleo-flow indicators trending northeast. This zone has the highest degree of areal scour with thin, discontinuous and relatively unweathered till. The second zone, GTZ 2, is an area where the broad northeast flowset is crosscut locally by ice flow indicators that converge into troughs that now form a series of north trending fjords in the north of the study area. This overprinted landscape is found to propagate inland forming a channelized system, leading way to linear erosion. The modern icecap resides in GTZ 3, which inherited the broad northeast flowset, but is overprinted in valleys by eastern flows funneling into the fjords to the east, as well as western flows flowing from the modern icecap. In the central area, there is a rolling terrain of thicker till (GTZ 4) that is distinguished by its lack of subglacial features. The final contrasting landscape (GTZ 5) is characterized by southeast trending bedrock features (most likely enhanced by southeast flowing ice) and associated perpendicular moraines. GTZ 5 is also characterized by highly weathered bedrock, and locally by landform assemblages recording late deglacial readvances of thin lobes including moraines and striated outcrops. Geochemical studies for each of these landscapes lead to additional insights, characterizing the five zones further. The geochemical studies took advantage of two till sample databases taken over the study area for exploration purposes by Peregrine Diamonds LTD. The chemical index of alteration (CIA) was applied to compare erosion in the different zones. High CIA values indicate high weathering, where low CIA values low weathering. GTZ 1 is characterized by low CIA values (low weathering footprint), and GTZ 5 is characterized by high CIA value (highly weathered). To study if the GTZs had a distinct geochemical signature, as well as a signature landscape, multivariate geochemical statistics (Principal Component Analysis and Linear Discriminant Analysis) were done over the study area. Interestingly, it was found that the GTZs have geochemical signatures, which reflect the role of underlying bedrock, weathering patterns, glacial dispersal, and the complex relationships between subglacial dynamics and landscape evolution. To determine if the GTZs could be predicted by the till geochemistry, linear discriminant analysis was subsequently applied. The results indicate that the till geochemical data has a predictive capacity with an accuracy of 83.78%, which brings insight into the relationship between glacial landscapes and till composition. With this multi-proxy approach and building from previous studies, a conceptual model was developed for the study area. During the Last Glacial Maximum (LGM), the study area was inundated by the Laurentide Ice Sheet (LIS), with the Hall Ice Divide parallel to the axis of the peninsula with ice flowing from the divide to the northeast and southwest. As ice thinned, GTZ 1, an area once inundated with warm-based ice, as shown by evidence of areal scour and low CIA values, switched to being cold-based ice preserving an older landscape. Though GTZ 1 was under cold-based ice, warm-based conditions still prevailed within the channelized flow zones, which characterize GTZ 2. Evidence of this is found in the striation record, as well as the low CIA value indicative of low weathering (or high erosion). This may reflect a transition from LGM (thick-based ice) to thinner, topographically controlled ice, with cold-based ice in interfluves and hilltops, during early deglaciation. The catchment zones of the channelized system locally extend near the central area (GTZ 4) which is reflected in dispersal patterns and the striation record. As the LIS retreated, it went through a series of southeastward readvances and surges (GTZ 5). Though the ice was warm-based near the moraines in GTZ 5, prevailing cold-based conditions prevailed during most of the last glacial cycle, and the late deglacial readvances had limited erosion capacity and did not overprint the cold-based landscape significantly. This is shown by the CIA values indicative of high weathering, and lack of subglacial landforms. Series of pro-glacial lakes also formed in front of the retreating lobe. Ice is needed over GTZ 1 to prevent these lakes from draining northward. This thin ice was most likely cold-based, preserving the older GTZ 1 landscape of areal scouring. The glacial landscape of Hall Peninsula appears to record a switch from uniform warm-based LGM ice, which was laterally extensive, to localized channel flows in the fjords during deglaciation and intervening cold-based ice. The change in the geometry and basal thermo-mechanical conditions may be the prologue to the separation of the modern day ice cap from the LIS.

Esse impacto diminui consideravelmente a qualidade ambiental das bacias hidrográficas, pois a conservação da vegetação para a preservação dos recursos naturais, principalmente da água, é de extrema importância para o amortecimento da pressão das atividades antrópicas. O presente estudo teve como objetivo realizar uma avaliação nos ambientes de proteção da bacia hidrográfica do rio Jundiaí-Mirim, situada entre os municípios de Jundiaí, Jarinu e Campo Limpo Paulista, utilizando a paisagem como fator determinante para sua análise, proporcionando um maior entendimento de seus ambientes de proteção, seu estado atual em função da vulnerabilidade ambiental e da ocupação e uso das terras, possibilitando mensurar quantitativamente e qualificativamente através de um índice de eficiência ambiental da paisagem e classes de tipificação territorial de acordo com o grau de vulnerabilidade ambiental, gerando subsídios consistentes para a elaboração de um plano de gestão ambiental para a área. O trabalho contemplou um plano de amostragem com 91 pontos de coleta de dados na bacia hidrográfica. A avaliação e análise dos dados resultou em um um índice de eficiência ambiental da paisagem médio de 38%, variando entre 23% e 68%. Em uma escala de complexidade frente aos impactos ambientais e considerando como ambientes de proteção os fragmentos florestais, foi possível tipificar a área da bacia hidrográfica em cinco classes de gestão; em que, a Classe E apresenta os níveis mais críticos de qualidade ambiental e de forma crescente, a Classe A os níveis menos críticos. Portanto os resultados mostraram que 11% da área pertence a Classe E, 31% pertence a Classe D, 29% pertence a Classe C, 23% pertence a Classe B e apenas 6% pertence a Classe A. A tipificação das áreas permitiu elaborar um plano de gestão ambiental, com programas e projetos de acordo com os níveis de perturbação e vulnerabilidade ambiental para cada uma das 5 classes em cada uma das 18 sub-bacias. / The occupation of natural areas is the product of economic growth of the cities and causes irreversible damage to the environment, reduces large areas of vegetation to small forest fragments. This impact significantly reduces the environmental quality of river basins, for the conservation of vegetation for the preservation of natural resources, especially water, it is extremely important for the damping pressure of human activities. The study aimed to carry out an assessment in protective environments watershed of Jundiaí-Mirim River, located between the cities of Jundiaí, Jarinu and Campo Limpo Paulista, using the landscape as a determining factor for analysis, providing a better understanding of their protection of environments, its current state as a function of environmental vulnerability and the occupation and use of land, making it possible to measure quantitatively and qualificativamente through an index of efficiency and territorial typing classes according to the degree of apparent environmental vulnerability, generating consistent subsidies the development of an environmental management plan for the area. The work comprises a sampling system with 91 data collection points in the watershed. The evaluation and analysis of the data resulted in an average rate of apparent efficiency of 38% landscape, ranging between 23% and 68%. On a scale of complexity compared to the environmental impacts and considering how the forest fragments protected environment, it was possible to typify the area of watershed management in five classes; in that, the Class E features the most critical levels of environmental quality and increasingly, the Class A the least critical levels. Therefore the results showed that 11% of the area belongs to Class E, 31% belongs to Class D, 29% belong to Class C, 23% belong to Class B and only 6% belong to Class A. The typification of areas allows prepare an environmental management plan, with programs and projects according to levels of nuisance and environmental vulnerability for each of the five classes in each of the 18 sub-basins.

From this perspective, traditional communities have been distinguished by their different forms of social organization and appropriation of natural resources. Despite many achievements in the legal framework, the realization of their rights is still hampered by many factors and opposing actors. The case of quilombo communities appears to be emblematic in this sense. Although the Federal Constitution recognizes quilombos property rights over their territories, there has been no guarantee of these communities permanence, due to their social, political and environmental vulnerability. This complex scenario, characteristic of so-called socio-environmental conflicts, refers to the theoreticalframework of the Political Ecology and the Environmental Justice movement. For empirical research, we selected two quilombo communities in the estate of Paraíba: Paratibe, located in the capital of the estate, and Senhor do Bonfim, located in the rural area of the municipality of Areia. The methodologychosen,called ethnography of socio-environmental conflicts (LITTLE, 2006),proves to be appropriate as we recognize that anthropology, in addition to maintaining a strong affinity with the quilombola theme, can contribute greatly to the collection and interpretation of data. While using landscape as prime unit of analysis, instead of concentrating research in a particular social group, the proposed methodology focuses on the socio-environmental conflict, beyond the local level, by listing the various actors involved, their interests, strategies, alliances and quotas of power, including considering the role of "natural agency". With this work, we intend to point out how the quilombola struggle falls in the current debate on development and sustainability that permeates all sectors of society. To do so,it is necessary not to restrain to technical and economic aspects, but also consider historical, social, cultural and political factors. It is important to understand that the adverse social and environmental impacts, even affecting people and groups unequally, affect the whole society. In this sense, from the quilombola example, we aim to point out that it is only through a review of concepts and an interdisciplinary approach to the contemporary problems that we may aspire to a more just, democratic and sustainable society, in all respects. / Num contexto de consenso crescente acerca da insustentabilidade do modelo de produção e consumo da sociedade contemporânea, têm se aberto espaços para discutir novos modelos de desenvolvimento, socialmente justos e ambientalmente sustentáveis, favorecendo um processo de identificação, visibilização e valorização de formas alternativas de relação homem-natureza. Sob essa perspectiva, as comunidades tradicionais têm se destacado por suas formas diferenciadas de organização social e apropriação dos recursos naturais. Apesar das muitas conquistas no marco legal, a efetivação de seus direitos ainda esbarra em diversos fatores e atores contrários. O caso das comunidades quilombolas revela-se emblemático nesse sentido. Embora a Constituição Federal de 1988 reconheça o direito à propriedade de seus territórios, isso não se traduziu em garantia da permanência dessas comunidades, em função de sua vulnerabilidade social, política e ambiental. Esse cenário complexo de disputa, característico dos chamados conflitos socioambientais, remete ao marco teórico da Ecologia Política e do movimento por Justiça Ambiental. Para a pesquisa empírica, selecionamos duas comunidades quilombolas da Paraíba: Paratibe, localizada na capital paraibana, e Senhor do Bonfim, situada na área rural do município de Areia, interior do estado. A escolha pela metodologia, denominada etnografia dos conflitos socioambientais (LITTLE, 2006), justifica-se por reconhecer que a Antropologia, além de manter grande afinidade com a temática quilombola, pode contribuir bastante para o levantamento e leitura dos dados. Ao lançar mão da paisagem como unidade de análise privilegiada, em vez de concentrar a pesquisa em um grupo social particular, a metodologia proposta tem como foco central o conflito socioambiental, extrapolando o âmbito local, ao inventariar os diversos atores envolvidos, seus respectivos interesses, estratégias, alianças e cotas de poder, inclusive considerando o papel da agência natural . Com o presente trabalho, pretendemos apontar de que forma a luta quilombola se insere no atual debate sobre desenvolvimento e sustentabilidade que permeia todos os setores da sociedade. É preciso, para tanto, não se restringir a aspectos técnicos e econômicos, mas considerar também fatores históricos, sociais, culturais e políticos. É importante compreender que os impactos sociais e ambientais nefastos, ainda que afetem pessoas e grupos de forma desigual, atingem o conjunto da sociedade. Nesse sentido, a partir do exemplo quilombola, visamos apontar que será somente por meio de uma revisão de conceitos e de um enfoque interdisciplinar dos problemas da contemporaneidade que poderemos almejar uma sociedade mais justa, democrática e sustentável, sob todos os aspectos.

De svenska torparna var en delmängd av det obesuttna folket, en samhällsklass som var särskilt utbredd under 1700 och 1800-talen. Torparna ägde ingen egen mark utan fick i stället bo i små och enkla torp på någon annans mark i utbyte mot betalning, antingen i pengar eller dagsverke. Torparna, särskilt de i Harbo, var oftast tvungna att ägna sig åt många olika sysslor för att få ekonomin att gå ihop. Det arkeologiska intresset för torp har traditionellt sett inte mötts med särskilt mycket entusiasm, till stor del på grund av de är relativt moderna och därför inte ansetts lämpliga att undersöka arkeologiskt. Över de senaste decennierna har denna uppfattning långsamt börjat skifta, med flera forskare som ägnar sig åt fälten historisk och samtidsarkeologi. Denna uppsats fokuserar på två torp i Harbo socknen och ämnar att belysa torparnas sociala position utifrån kyrkoböcker och historiska kartor. Utöver detta kommer torplämningarna att undersökas i person för att avgöra bevaringen av dessa, samt för att notera eventuella ytterligare fynd på platsen. Slutligen kommer jag diskutera resultaten av undersökningen såväl som värdet av att studera torp arkeologiskt. / The Swedish crofters were a subset of the unpropertied people, a social class especially prevalent during the 18th and 19th centuries. The crofters owned no ground of their own but were instead allowed to live in small and simple crofts on someone else’s land in exchange for payments, either in form of money or labour. The crofters, especially true for the ones in Harbo, usually had to delve into many different occupations to try to make ends meet. The archaeological interest for crofts has traditionally not been met with much enthusiasm, in large because of them being relatively modern and therefore not seen as fit for archaeological evaluations. Over the past decades this sentiment has slowly begun to change, with many scientists devoting themselves to the subfield of historical and present-day archaeology which places a particular focus on these remains. This essay focuses on two crofts in Harbo socknen and aims to shed light on the crofters’ social position and existence using written church records and historical maps. Moreover, the remains of the crofts will be examined in person as to study the preservation of these, as well as to note eventual additional findings. Finally, I will discuss the findings of my study as well as discuss the importance of the archaeological study of crofts.

I Jönköping finns idag tre synliga bronsåldersgravar fortfarande stående. I början av1900-talet var detta numret 10. Vissa fynd från bronsåldern i området som Sagaholmshögenhar fått mycket uppmärksamhet av forskare, men få landskapsanalyser har utförts över dettaområdet. På andra håll har landskapsanalyser av gravhögar ofta utförts över betydligt störreområden, och dessa har fått tolkningar som bland annat territoriemarkörer baserat påmonumentens visuella aspekt. Uppsatsen analyserar bronsålderslandskapet i Jönköping utifrånsiktlinjer med hjälp av GIS, och med syftet att undersöka relationen mellan de monumentalagravarna och andra synliga aspekter av landskapet för att försöka nå varför dessa uppfördesdär de står. Resultaten av analysen visar att synlighet troligen inte var en särskilt betydandefaktor för uppförandet av gravarna, men att ett samband i intervisibiliteten mellan dessa kananas, samt belyser uppsatsen några källkritiska problem med tillgängliga strandlinjemodelleroch digital fornminnesdata. / In Jönköping there exists today three visible and still standing barrows from the bronze age.In the beginning of the 20th century these numbered 10. Some findings från the bronze age inthis area like the Sagaholm-barrow have garnered a lot of attention by researchers, but fewlandscape analyses havebeen performed over the area. In other parts of the country landscapeanalyses have been performed across much larger areas, and these have gotten interpretationssuch as markers of territory based on the visual aspects of these monuments. This thesisanalyses the bronze age landscape in Jönköping based on sightlines with the aid of GIS, andwith the goal to explore the relationship between the monumental graves and other visibleaspects of the landscape in order to try and reach an understanding as to why these arestanding where they are. The results of the analysis show that visibility likely wasn’t anespecially important factor in raising the graves, but that a correlation regarding intervisibilitycan be suspected. Furthermore the thesis shines light on a few sources of critique with theavailible shoreline models, as well as the digital data on ancient remains.

No / Geophysical survey techniques are a highly visible part of the scientific toolkit that is now used by archaeologists. In this paper, the history of the use of geophysical techniques in archaeology will be discussed, as will significant research themes associated with the most widely used prospecting devices. It is apparent that while the use of geophysical techniques is at an all-time high, there are many key areas where prospecting is rapidly developing. Some of the advances relate to fundamental aspects of the techniques, while others dictate how we undertake survey in the future. There is a movement away from pre-gridded survey areas towards real-time GPS for navigation. This allows greater integration, or fusion, of disparate data sources using visualization techniques derived from associated disciplines. The analysis of landscapes has become a major component of the application of new technology and there are many challenges to be tackled, including how to analyse and interpret significant archaeology within large-scale, data-rich, multi-technique investigations. The reflective nature of the review acknowledges the important role of Archaeometry in the development of archaeological geophysics.

Wildlife management and natural resource policy decisions are increasingly being made at the landscape level. Understanding the relationship between modification and the pattern of land classes may minimize potential impacts and enhance the complement of wildlife species. Twenty-four expressions were selected for landscape analysis that describe the spatial heterogeneity, fragmentation, edge characteristics, and connectivity of pattern. Metric relationships were characterized across a variety of landscapes. Cluster analysis organized the metrics into classes quite different from the classification categories used in the literature. Cluster membership reflected the number of land classes, the amount and distribution of forest cover, number of forest patches, patch position, patch shape, patch radius, and edge length. Cartographic modeling was used to determine how modification influenced landscape pattern. The models depicted spatial relationships resulting from proposed landscape changes. Timber harvest schemes with a few large units and those in clustered arrangements led to less fragmentation than those schemes with several small units or those dispersed across the landscape. The placement of roads had either an invasive or partitioning effect on landscape pattern. Discriminant analysis rated the effectiveness of pattern expressions for environmental assessment. Metric effectiveness differed among the timber harvest, road expansion, and deforestation modification schemes. The utility and limitations of each expression was discussed. Sensitivity analyses examined the effects of changing spatial scale on pattern description. Scale influence was dependent upon landscape complexity, distribution of land classes, and the size and shape of those classes. The loss of ability to detect localized variability, to differentiate among spatial patterns, and to represent boundary detail accompanied the use of large pixels (420m²). There was evidence that spatial scale influences habitat evaluation. Semivariogram analysis assessed the constancy of expression behavior during changes in scale and presented the limits of tolerance for using large pixels in pattern analyses. The variability observed suggested that pattern misrepresentation occurred at coarse resolution levels. The successful application of landscape analysis depends on the ability to quantify pattern. By analyzing and understanding selected aspects of landscape pattern, I have examined how wildlife management can be enhanced through a knowledge of the landscape. / Ph. D.

Bayesian network (BN) structure learning from data has been an active research area in the machine learning field in recent decades. Much of the research has considered BN structure learning as an optimization problem. However, the finding of optimal BN from data is NP-hard. This fact has driven the use of heuristic algorithms for solving this kind of problem. Amajor recent focus in BN structure learning is on search and score algorithms. In these algorithms, a scoring function is introduced and a heuristic search algorithm is used to evaluate each network with respect to the training data. The optimal network is produced according to the best score evaluated. This thesis investigates a range of search and score algorithms to understand the relationship between technique performance and structure features of the problems. The main contributions of this thesis include (a) Two novel Ant Colony Optimization based search and score algorithms for BN structure learning; (b) Node juxtaposition distribution for studying the relationship between the best node ordering and the optimal BN structure; (c) Fitness landscape analysis for investigating the di erent performances of both chain score function and the CH score function; (d) A classifier method is constructed by utilizing receiver operating characteristic curve with the results on fitness landscape analysis; and finally (e) a selective o -line hyperheuristic algorithm is built for unseen BN structure learning with search and score algorithms. In this thesis, we also construct a new algorithm for producing BN benchmark structures and apply our novel approaches to a range of benchmark problems and real world problem.

As aves de rapina, assim como os outros grupos animais, não estão distribuídas de maneira uniforme nos diferentes hábitats que compõem a paisagem terrestre. Conhecer e entender os fatores (e as implicações) que levam as espécies a escolher um determinado hábitat é questão essencial nos estudos de ecologia. Esse tema ganha ainda mais importância não só pela escassez de informações sobre a ecologia e história natural das aves de rapina na região Neotropical, mas também, pelo atual cenário de alteração dos hábitats. Estes são modificados rapidamente sem que haja um conhecimento básico da relação espécie/hábitat e dos efeitos provocadas por tais alterações. Dessa maneira, a presente tese teve como objetivo principal verificar o uso e a seleção de hábitat por aves de rapina diurnas em uma paisagem heterogênea (151. 866 ha) na região central do Estado de São Paulo (22° 15′ S; 47° 49′ W), onde a Estação Ecológica de Itirapina (EEI) foi considerada como área núcleo. Ainda, foi também alvo desse estudo estimar a área de vida de três espécies de rapineiros (Falco femoralis, Rupornis magnirostris e Heterospizias meridionalis) por meio de rádio-telemetria; verificar a eficiência de captura das aves de rapina frente a dois tipos de armadilhas, bal-chatri e goshawk; e elaborar um mapa de uso/ocupação do solo da área em questão, bem como analisar a paisagem no entorno da EEI. Entre setembro de 2005 e fevereiro de 2007 foram registradas 19 espécies de Falconiformes (Pandionidae n =1, Falconidae n = 5, Accipitridae n = 13) em uma paisagem essencialmente ocupada por monoculturas (cana-de-açúcar 22 %, laranja 14 %, eucalipto 13 %) e pastagens (21%). A riqueza média dos Falconiformes em áreas de monoculturas foi de 4,6 espécies e nas áreas naturais 10,3. A composição de espécies da taxocenose se mostrou mais relacionada às outras de área abertas sob influência do Cerrado. Um total de 48 indivíduos, pertencentes a cinco espécies, foram capturados pelos dois tipos de armadilhas. O sucesso de captura geral foi de 15,3 % (n = 33) para a armadilha bal-chatri e de 1 captura a cada 11,8 dias (8,5 %) para goshawk trap (n = 15). Implicações e limitações referentes à captura das aves de rapinas em áreas abertas foram também discutidas. A média da área de vida pelo método Kernel adaptativo (KA) 95 % foi de 1.329 ± 780 ha para F. femoralis, 129 ± 140 ha para R. magnirostris e de 1.883 ha para o indivíduo de H. meridionalis. A média da área de vida de F. femoralis foi 2,8 maior em áreas alteradas quando comparada a áreas naturais. De maneira geral, a qualidade do hábitat parece ter influenciado nos diferentes valores de requerimento de área apresentado pelos indivíduos e, também, na seleção/rejeição dos diferentes hábitats. Na maioria dos casos, as monoculturas foram rejeitadas, enquanto as áreas naturais foram selecionadas pelas aves de rapina. Cana-de-açúcar foi rejeitada por todas as aves de rapina. O único ambiente alterado utilizado em maior proporção que o esperado foi pastagem, selecionada por quatro das 10 espécies analisadas. Em contrapartida, três espécies evitaram este hábitat. Este é o primeiro estudo a avaliar a seleção de hábitat por Falconiformes no Brasil e demonstra que o intensivo incremento de áreas para agricultura pode afetar negativamente até mesmo as espécies mais abundantes e generalistas, contrário a algumas generalizações da literatura. A interação entre estrutura do hábitat, disponibilidade de presas, morfologia e comportamento de caça parece explicar tanto o tamanho da área de vida requerida quanto a utilização diferenciada dos diferentes tipos de hábitats. / Raptors, similarly to other animal groups, are not randomly distributed in the different habitats in the terrestrial landscape. Knowing and understanding the factors (and implications) influencing these species to chose a certain habitat are essential in ecological studies. This subject has become even more important not only because of the lack of information on the ecology and natural history of raptors of the Neotropics, but also because of current scenario of habitat changes. Areas are being rapidly modified without a basic knowledge of the species/habitat relationship and the effects it may cause. Thus, the main goal of this thesis was to examine habitat use and selection by diurnal birds of prey in a heterogeneous landscape (151. 866 ha) in the central region of state of São Paulo (22° 15′ S; 47° 49′ W), where the Estação Ecológica de Itirapina (EEI) was considered the central area. Also, this study aimed at estimating the home range size of three raptor species (Falco femoralis, Rupornis magnirostris and Heterospizias meridionalis) through radio-telemetry; examining the efficiency of capture of birds of prey using two types of traps, bal-chatri and goshawk; and mapping land use/occupation of the study area and making the landscape analysis around the EEI. Between September 2005 and February 2007, 19 species of Falconiformes (Pandionidae n = 1, Falconidae n = 5, Accipitridae n = 13) were observed in a landscape basically occupied by monocultures (sugar cane 22 %, orange 14 %, eucalyptus 13 %) and pastures (2 1%). The average richness of Falconiformes in areas occupied by a monoculture was 4,6 species and 10,3 in natural areas. The species composition of the assemblage was more similar to those of other open areas influenced by Cerrado. Forty-eight individuals from five species were captured in the two types of traps. The general capture success was 15.3 % (n = 33) for the bal-chatri trap and 1 capture every 11,8 days (8,5 %) for the goshawk trap (n = 15). Implications and limitations of the capture of birds of preys in the areas were also discussed. The average home range obtained with the 95 % adaptive Kernel method (AK 95%) was 1.329 ± 780 ha for F. femoralis, 129 ± 140 ha for R. magnirostris and 1.883 ha for the individual of H. meridionalis. The average home range of F. femoralis was 2.8 higher in altered areas when compared to natural ones. In general, habitat quality seems to have influenced the different values of home range requirement of individuals, and also, in the selection/rejection of the different habitats. In most cases, monocultures were rejected, while natural areas were selected by raptors. Sugar cane plantations were rejected by all raptors. The only altered habitat used more than expected was pastures, selected by four of ten species analyzed. However, three species avoided this habitat. This is the first study to evaluate habitat selection by Falconiformes in Brazil and demonstrate that the increase of areas for agriculture may negatively affect even the most abundant and generalist species, contrary to some generalizations described in the literature. The interaction among the habitat structure, prey availability, morphology and hunting behavior seems to explain home range size requirements as well as the differential use of the various types of habitats.
