ATLANTIC-PRIMATES: a dataset of communities and occurrences of primates in the Atlantic Forests of South America

Primates play an important role in ecosystem functioning and offer critical insights into human evolution, biology, behavior, and emerging infectious diseases. There are 26 primate species in the Atlantic Forests of South America, 19 of them endemic. We compiled a dataset of 5,472 georeferenced locations of 26 native and 1 introduced primate species, as hybrids in the genera Callithrix and Alouatta. The dataset includes 700 primate communities, 8,121 single species occurrences and 714 estimates of primate population sizes, covering most natural forest types of the tropical and subtropical Atlantic Forest of Brazil, Paraguay and Argentina and some other biomes. On average, primate communities of the Atlantic Forest harbor 2 ± 1 species (range = 1–6). However, about 40% of primate communities contain only one species. Alouatta guariba (N = 2,188 records) and Sapajus nigritus (N = 1,127) were the species with the most records. Callicebus barbarabrownae (N = 35), Leontopithecus caissara (N = 38), and Sapajus libidinosus (N = 41) were the species with the least records. Recorded primate densities varied from 0.004 individuals/km 2 (Alouatta guariba at Fragmento do Bugre, Paraná, Brazil) to 400 individuals/km 2 (Alouatta caraya in Santiago, Rio Grande do Sul, Brazil). Our dataset reflects disparity between the numerous primate census conducted in the Atlantic Forest, in contrast to the scarcity of estimates of population sizes and densities. With these data, researchers can develop different macroecological and regional level studies, focusing on communities, populations, species co-occurrence and distribution patterns. Moreover, the data can also be used to assess the consequences of fragmentation, defaunation, and disease outbreaks on different ecological processes, such as trophic cascades, species invasion or extinction, and community dynamics.

We also request that researchers and teachers inform us of how they are using the data. © 2018 by the The Authors. Ecology © 2018 The Ecological Society of Americ

Co-pirólise de resíduos de polietileno com gasóleo pesado da Bacia de Campos Co-pirolysis of Polyethylene Waste with the Campos Bacia Heavy Oil

Neste estudo, quatro misturas de PEBD pós-consumo com gasóleo pesado da Bacia de Campos, em diferentes proporções, foram submetidas à pirólise em atmosfera inerte a 550 °C. Os líquidos pirolíticos foram caracterizados por cromatografia em fase gasosa acoplada à espectrometria de massas (CG/EM). A pirólise do gasóleo puro forneceu elevado teor de resíduo e apenas 4% hidrocarbonetos na faixa do óleo diesel. Por outro lado, a pirólise da mistura de gasóleo com PEBD (na proporção 1/0,5 em m/m) forneceu 20% de hidrocarbonetos leves com elevada produção de óleo pirolítico (96%). Desta forma, pode-se concluir que a pirólise de resíduos plásticos com gasóleo pesado pode ser uma tecnologia promissora não apenas para aumentar a formação de hidrocarbonetos leves derivados de gasóleo pesado como também para o reaproveitamento de resíduos plásticos.In this study, four mixtures of LDPE post consumer with heavy gas from the Campos Basin, in different proportions, were subjected to pyrolysis in an inert atmosphere at 550 °C. The pyrolytic liquids were characterized by gas chromatography coupled to mass spectrometry (GC/MS). Pyrolysis of pure diesel supplied large amounts of waste oil and only 4% in the range of diesel. On the other hand, the pyrolysis of LDPE mixture of diesel (at the ratio 1/0,5 m/m) provided 20% of light hydrocarbons with high production of pyrolytic oil (96%). The formation of high levels of paraffins and olefins in the range of diesel oil during the co-pyrolysis suggests a promising technology for recycling of plastic waste

Impact of chemical oxidation on Brazilian soils

In this work, the impacts on the mineralogical composition and on the physico-chemical properties of two representative categories of Brazilian soils - a vertisol (V) and a kandiudult (P) - after treatment with Fenton reagent were studied. The clay minerals presented in the V (rich in 2:1 expansive clay) have been degraded with this reagent application. In the other, P, rich in kaolinite, there was no significant change in its clay mineralogy after this treatment. Furthermore, the cation exchange capacity (CEC) of V was dramatically diminished and consequently can cause the soil infertility by the reduction of water and nutrients retention

Desenvolvimento sustentável e pensamento complexo: estudo de caso: o uso de argilas como catalisadores

Use of clays as catalyzers in heterogeneous processes has increased significantly given their low cost, safety and commercial availability. However, interconnected political, economic, social, environmental, geological, and chemical aspects should be considered for chemical processes to satisfy sustainable development concepts. This concept requires complex thinking involving different areas of knowledge in dialogue, contrasting with classical thought, which is linear and Cartesian. Thus, this paper discusses the principles of complex thought in the concept of sustainable development exemplified by use of clay as a clean technology in organic synthesis

A implementação do programa Bolsa Família: as experiências de São Francisco de Itabapoana e Duque de Caxias Implementation of Brazil's Family Allowance Program: experiences at São Francisco de Itabapoana and Duque de Caxias

O artigo discute os resultados da pesquisa "Implementação do Programa Bolsa Família no Estado do Rio de Janeiro: as experiências de São Francisco de Itabapoana e Duque de Caxias" realizada durante os anos de 2004 e 2005 com o apoio do CNPQ e que envolveu pesquisadores e alunos da ENSP/FIOCRUZ, UFF e UERJ. O objetivo do estudo foi analisar a implementação e a gestão local do programa Bolsa Família, identificando os principais contornos desta intervenção pública nos municípios selecionados. A aproximação com a dinâmica política e institucional local e com os mecanismos de responsabilização dos gestores, conformação de coordenações integradas e intersetoriais, oferta e acompanhamento das ações de saúde e educação e definição dos papéis dos diferentes entes federativos na operacionalização do programa contribuiu para identificar as principais tensões e os desafios ligados ao alcance de maior eqüidade e justiça social no campo das políticas de transferência condicionada de renda no país.<br>This paper discuss the findings of a study examining the Implementation of Brazil's Family Allowance Program in Rio de Janeiro at São Francisco de Itabapoana and Duque de Caxias, conducted in 2004 - 2005 with the support of the Brazilian Science and Technology Research and Development Council (CNPq) and collaboration among ENSP-FIOCRUZ, UFF and UERJ. Its purpose is to analyze this implementation process and local management practices, identifying the main contours of this program. An examination of its political and institutional dynamics, accountability mechanisms, intersectoral arenas, investments in healthcare and education, and intergovernmental arrangements helps outline some of the conflicts, tensions and challenges associated with conditional cash transfers as a core policy in the battle against poverty and social inequalities

Insuficiência renal aguda secundária a acidentes ofídicos botrópico e crotálico. Análise de 63 casos

Sessenta e três pacientes com insuficiência renal aguda secundária a acidente ofídico foram tratados no CTI do Hospital das Clínicas da UFMG. Em 32 pacientes (51%) o acidente foi produzido por serpentes do gênero Bothrops (grupo bio-trópico) e em 32 pacientes (49%) pela cascavel sul-americana (grupo crotálico). As principais complicações apresentadas pelos pacientes foram a uremia (100% dos casos), hiperpotassemia (89% dos casos), anemia (78% dos casos), infecção urinária (37% dos casos), hiper-hidratação (17% dos casos), parada cardíaca (14% dos casos) e edema agudo dos pulmões (11% dos casos). Cinco pacientes do grupo crotálico (16%) tiveram insuficiência respiratória aguda atribuída à ação neurotóxica do veneno, quatro dos quais se recuperaram completamente. Sete pacientes do grupo botrópico (22%) tiveram necrose cortical renal diagnosticada em cinco através da biópsia renal e em dois na necropsia. Quarenta e cinco pacientes (71%) foram tratados com diálise peritoneal e a hemodiálise foi necessária em dois pacientes, um dos quais havia sido submetido a diálise peritoneal. Em 17 pacientes (27%) o tratamento foi conservador. Cinqüenta e cinco pacientes receberam alta hospitalar, quatro dos quais com insuficiência renal crônica secundária a necrose cortical renal e oito (13%) faleceram. Os óbitos foram atribuídos a edema pulmonar agudo em quatro pacientes, a estado de choque em dois pacientes e a coma e infecção respiratória após parada cardíaca em dois pacientes
