While bird diversity in the Atlantic Forest can be considered well-known, how the communities have been affected by deforestation and habitat fragmentation is not. We studied birds in 10 forest fragments of distinct sizes (all originally within the Atlantic Forest) in southern Bahia. In 5,391 bird encounters, we found 251 species, with 46 endemics and eight considered globally vulnerable or endangered. We also compiled a list of the 380 species that should comprise the expected regional assemblage, and found that only 66% of these species were present in all the fragments combined. Only 9% of all observed species were found in all fragments. The largest fragment (700 ha) had the greatest number of endemic species (40), and seven threatened species. All fragments had some conservation-important species (some were found in one or a few fragments), but no fragment included them all. Fragments shared 10% of endemic species, but overall, the contingent of endemics was unique in each fragment. Finally, most functional traits of bird assemblages decreased with increasing fragment size. Neither species richness nor similarity correlated with fragment size or distance between fragments, and unknown, non-random factors probably influence the likelihood of species survival in each fragment. Thus, to ensure the persistence of threatened species, as well as maintain the most common species, conservation management decisions should include all fragments together because no single fragment is most representative of the local community.

Orientador: Heleno Rodrigues Correa Filho Dissertação (mestrado) - Universidade Estadual de Campinas, Faculdade de Ciencias Medicas Resumo: O reconhecimento das condições de produção e dos ambientes e processos de trabalho, e suas repercussões sobre a saude e vida dos trabalhadores e populações potencialmente afetadas representa elemento fundamental para as politicas de saúde publica, meio ambiente e sustentabilidade. Estudos de coortes ocupacionais podem contribuir para tal objetivo. O presente estudo buscou reconhecer a logistica de estrategias, metodos, tecnicas e elementos significativos para a recuperacao de dados e informações necessarias a reconstrução de coortes ocupacionais no contexto brasileiro. Realizou-se uma revisao sistematica da literatura sobre reconstrução de coortes ocupacionais nacionais e estudo do caso Shell-Cyanamid-Basf, ocorrido em Paulinia/SP. Foram identificados e explorados desafios metodologicos, as principais variaveis, dados e informações relacionadas, os atores sociais e sua atuação, concluindo-se pela indicação de acoes sistematizadas e de estrategias combinadas de busca, e pelo reconhecimento da importancia do protagonismo dos trabalhadores nas varias etapas do processo de reconstrução das coortes ocupacionais como ações fundamentais e qualificadoras desses estudos e dos processos de atenção e vigilância a saude dos trabalhadores. Abstract: The establishment of Public Policies towards Public and Environmental Health and Sustainability depends fundamentally on the recognition of how the means of production and the work processes impact over life and health of workers and the general population. Studies of occupational cohorts may contribute to such objectives. The present study aimed at recognizing the logistics of strategies, methods, techniques and relevant elements to ensure data and information retrieval to rebuilding occupational cohorts in the Brazilian context. A systematic literature review was conducted about Brazilian national occupational cohorts with special focus on de Shell-Cyanamid-Basf environmental spill-over case in Paulinia/SP. This allowed for identifying and exploring methodological breakthroughs to collect main variables, data and information related with systematic research strategies. Organized workers were recognized as key proactive players that developed actions combining social strategies to find their old fellows and job companions to rebuild their occupational cohort. They helped to qualify public actions to implement health services assistance and epidemiological surveillance on workers's health. Mestrado Epidemiologia Mestre em Saúde Coletiva

Orientador: Heleno Rodrigues Correa Filho Tese (doutorado) - Universidade Estadual de Campinas, Faculdade de Ciencias Medicas Resumo: Contemporaneamente, o câncer vem sendo considerado um grave problema de saúde pública em todo o mundo, observando-se aumento na mortalidade e nas taxas de incidência. No Brasil, representa a segunda causa de mortalidade. A maioria dos estudos epidemiológicos sobre exposição ocupacional e câncer tem sido realizada nos países desenvolvidos, com características sócio-econômicas diversas daquelas observadas em países não desenvolvidos. Nos países industrializados estima-se que as exposições ocupacionais sejam responsáveis por cerca de 4% de todos os cânceres humanos. Este estudo avaliou possíveis associações entre cânceres hematológicos e exposição a cancerígenos ocupacionais em pacientes residentes na Região Sul de Minas Gerais, representada por 130 municípios e 2.167.585 habitantes. A abordagem metodológica foi a de um estudo epidemiológico observacional, do tipo caso - controle, na razão de 1:1, com base em registros públicos realizados para casos de câncer atendidos e tratados no Sistema Único de Saúde da região. Controles foram pacientes usuários dos serviços de saúde da região, não portadores de diagnósticos compatíveis com câncer. O estudo incluiu 139 casos e 160 controles não emparelhados. Coletaram-se informações sobre exposição ocupacional às substâncias químicas, com destaque, para os agrotóxicos e os solventes orgânicos. Associações positivas, com significância estatística, entre cânceres hematológicos e exposições ocupacionais foram observadas, tanto para agrotóxicos (OR=3,471; IC95%=2,009-5,998), como também, para o grupo de solventes orgânicos, lubrificantes, combustíveis e tintas (OR=2,730; IC95%=1,503-4,960). Regressão logística evidenciou associação mais forte para os agrotóxicos (OR=3,976; IC95%=2,266-6,976), diante dos solventes, combustíveis e lubrificantes (OR=2,539; IC95%=1,398-4,614) após o ajustamento para idade Abstract: Contemporarily, the Cancer has been considered a serious problem of public health in whole world. Its standard of world-wide distribution presents important geographic variations, being observed an increase in the mortality and in the rates of incidence. In Brazil, the neoplasms represent the second more common cause of mortality. Almost the totality of the epidemiological studies searching to relate occupational exposition and cancer has been carried through in the developed countries, with diverse social and economic characteristics of those observed in countries like Brazil. In the industrialized countries it is esteemed that the occupational expositions are responsible for about 4% of all the human cancers. This study has as objective to study possible associations between hematological cancers and exposition to occupational carcinogens in resident patients in the south region of Minas Gerais, region which is composed by 130 cities and 2.167.585 inhabitants. The methodological approach is an epidemiological study of case - control type, in the rate of 1:1, based on carried through public registration for cases of cancer that entered and were treated in the Unique System of Health - SUS of the region. The study included 139 cases and 160 controls. Information had been collected on occupational and ambient exposition to chemical substances, with prominence, for the pesticides and the organic solvent. Associations between hematological cancers and exposition to occupational and ambient risks factors had been investigated, including pesticides and organic solvent. After calculating the Odds Ratio - OR of hematological cancers, with the respective intervals (IC 95%), it was concluded that the pesticides and the organic solvent can contribute to the cause of the hematological cancers Doutorado Saúde Coletiva Doutor em Saúde Coletiva
