ABSTRACT Brazil is home to many mountain ranges which harbor diverse avifauna. However, studies on the altitudinal distribution of Brazilian birds are still few and many have never been published, hampering both the dissemination of basic information and conservation actions. Here we present a critical review of ornithological studies undertaken in Brazilian mountain ranges, and propose a classification of geographic scope, altitudinal gradient, and methodology. Since 1922, 184 ornithological studies included altitude in some way in Brazil, encompassing a variety of research topics and species. About a quarter of these studies were never published in peer-reviewed journals, and 39% do not provide basic data on elevation nor link the bird species with sampling plots, thus limiting their applicability. The majority of studies are concentrated (83%) in southern and southeastern Brazil, especially in the Serra do Mar range, and so most data are associated with the Atlantic Forest. Gaps remain in other regions, such as Amazonia (Pantepui region). Most studies either did not sample the entire elevation gradient, were not standardized, lacked explicit hypothesis, or did not account for a seasonal sampling embracing the four seasons of the year, so interpretation of the observed patterns remains difficult. With this compilation, we organize the available information and point to future altitudinal research on birds, in addition to highlighting the importance of preserving habitats along altitudinal gradients in the mountainous regions in Brazil.

Abstract: En | Text: En | PDF: En

Abstract Oral candidiasis is a common fungal infection that affects the oral mucosa, and happens when Candida albicans interacts with bacteria in the oral microbiota, such as Streptococcus mutans, causing severe early childhood caries. C. albicans and S. mutans mixed biofilms are challenging to treat with conventional antimicrobial therapies, thus, new anti-infective drugs are required. Objective This study aimed to test a drug delivery system based on chitosan microparticles loaded with geranium and lemongrass essential oils to inhibit C. albicans and S. mutans mixed biofilms. Methodology Chitosan microparticles loaded with essential oils (CM-EOs) were obtained by spray-drying. Susceptibility of planktonic were performed according CLSI at 4 to 2,048 µg/mL. Mixed biofilms were incubated at 37ºC for 48 h and exposed to CM-EOs at 256 to 4,096 µg/mL. The antimicrobial effect was evaluated using the MTT assay, with biofilm architectural changes analyzed by scanning electron microscopy. RAW 264.7 cell was used to evaluate compound cytotoxicity. Results CM-EOs had better planktonic activity against C. albicans than S. mutans. All samples reduced the metabolic activity of mixed C. albicans and S. mutans biofilms, with encapsulated oils showing better activity than raw chitosan or oils. The microparticles reduced the biofilm on the slides. The essential oils showed cytotoxic effects against RAW 264.7 cells, but encapsulation into chitosan microparticles decreased their toxicity. Conclusion This study demonstrates that chitosan loaded with essential oils may provide an alternative method for treating diseases caused by C. albicans and S. mutans mixed biofilm, such as dental caries.

Abstract Background It is known that around 30% of patients have higher blood pressure (BP) values when examined at the office than at home. Worldwide, only 35% of patients with hypertension undergoing treatment have reached their BP targets. Objective To provide epidemiological data on BP control in the offices of a sample of Brazilian cardiologists, considering office and home BP measurement. Methods This is a cross-sectional analysis of patients with a hypertension diagnosis and undergoing antihypertensive treatment, with controlled BP or not. BP was assayed in the office by a medical professional and at home using home BP monitoring (HBPM). The association between categorical variables was verified using the chi-square test (p<0.05). Results The study included 2540 patients, with a mean age of 59.7 ± 15.2 years. Most patients were women (62%; n=1575). Prevalence rates of 15% (n=382) for uncontrolled white coat hypertension and 10% (n=253) for uncontrolled masked hypertension were observed. The rate of BP control in the office was 56.3% and at home, 61%. Meanwhile, 46.4% of the patients had controlled BP in and outside of the office. Greater control was observed in women and in the 49-61 years age group. Considering the new DBHA 2020 threshold for home BP control, the control rate was 42.4%. Conclusion BP control in the offices of a sample of Brazilian cardiologists was 56.3%; this rate was 61% when BP was measured at home and 46.4% when considering both the office and home.

Resumo Fundamento Sabe-se que em torno de 30% dos pacientes apresentam valores de pressão arterial (PA) mais elevados quando examinados no consultório do que em suas residências. No mundo, admite-se que apenas 35% dos hipertensos já tratados tenham alcançado meta pressórica. Objetivo Fornecer dados epidemiológicos sobre o controle da PA nos consultórios, em uma amostra de cardiologistas brasileiros, avaliado pela medida de consultório e monitorização residencial da pressão arterial (MRPA). Métodos Análise transversal. Observou-se pacientes com diagnóstico de hipertensão arterial, em tratamento anti-hipertensivo, podendo ou não estar com a PA controlada. A PA foi verificada no consultório por profissional médico, e no domicílio através da MRPA. A associação entre variáveis categóricas se deu por meio do teste do qui-quadrado (p < 0,05). Resultados Foram incluídos 2.540 pacientes, com idade média 59,7 ± 15,2 anos. A maioria dos pacientes eram mulheres (62%; n = 1.575). O estudo mostrou uma prevalência de 15% (n = 382) de hipertensão do avental branco não controlada, e 10% (n = 253) de hipertensão mascarada não controlada. A taxa de controle da PA no consultório foi 56,3%, e no domicílio, de 61%; 46,4% dos pacientes tiveram PA controlada no consultório e fora dele. Observou-se maior controle no sexo feminino e na faixa etária 49-61 anos. Observando o controle domiciliar com o novo ponto de corte das Diretrizes Brasileiras de Hipertensão Arterial de 2020, a taxa de controle foi de 42,4%. Conclusão O controle pressórico nos consultórios em uma amostra de cardiologistas brasileiros foi de 56,3%; 61% quando a PA foi obtida no domicílio, e 46,4% quando o controle foi observado tanto no consultório como no domicílio.

ABSTRACT Altitudinal migration in birds comprises seasonal movements between breeding and non-breeding areas in mountainous regions, attributed to biotic and abiotic factors. Different authors have suggested the existence of altitudinal migration between high and low areas of the mountains of the Atlantic Forest, with movement from high to low during the winter when birds would be fleeing the cold and in search of food, but there is no documented evidence. Through recaptures of understory birds, we investigated possible altitudinal migration in a region of the Atlantic Forest in Southeast Brazil. Twenty mist-nets were set at four locations between 15 and 729 m a.s.l. during 143 days of field work, distributed over 54 months and covering all seasons of the year. A total of 1946 birds (98 species) were captured/banded with 558 being recaptured (28.6%; 45 species). However, only 42 of the recaptures were at a different elevation. Most of the movements were of short distances and performed only once by birds, showing no seasonal pattern. These movements may be better interpreted as daily movements undertaken by birds of mixed-species flocks looking for food or moving around their respective home-ranges. Our results show that mist-nets may not be an effective tool in detecting altitudinal movements of birds and that other methods should be evaluated for this purpose.

Abstract: En | Text: En | PDF: En

Abstract Montane and submontane forest patches in the state of Bahia, Brazil, are among the few large and preserved Atlantic Forests remnants. They are strongholds of an almost complete elevational gradient, which harbor both lowland and highland bird taxa. Despite being considered a biodiversity hotspot, few ornithologists have surveyed these forests, especially along elevational gradients. Here we compile bird records acquired from systematic surveys and random observations carried out since the 1980s in a 7,500 ha private protected area: Serra Bonita private reserve. We recorded 368 species, of which 143 are Atlantic Forest endemic taxa. Some 16 and 13 species are threatened at the global and national levels, respectively. If one accounts for subspecies, the number of Brazilian threatened taxa raises to 21. Species composition differs between lower and higher elevations, in which case lowlands harbor Amazonia-related taxa, whereas highlands are the home of Atlantic Forest-related taxa.

Resumo Fundamentos: Com a criação do SUS, todos teriam acesso universal, integral e equânime à assistência de saúde de qualidade. Entretanto, existe grande lacuna de estudos escrutinizando o SUS no tocante à qualidade assistencial praticada. Esse fato é especialmente crítico para vítimas de infarto agudo do miocárdio com supradesnivelamento do segmento ST (IAMCSST), sendo a responsividade do sistema e o uso da reperfusão em tempo hábil fatores cardinais para obtenção de melhores resultados. Objetivo: Descrever a metodologia empregada no Registro VICTIM que tem como objetivo caracterizar e comparar o acesso e o uso de terapias efetivas e desfechos entre os pacientes com IAMCSST usuários do SUS e do sistema privado atendidos nos hospitais com capacidade de realizar angioplastia em Sergipe, tentanto identificar e mensurar eventuais disparidades na qualidade da assistência. Métodos e Resultados: O Registro VICTIM é um estudo observacional, iniciado em dezembro de 2014, e ainda em fase de coleta, com a intenção de investigar a epidemiologia do IAMCSST em Sergipe, os cursos temporal e geográfico dos pacientes até sua admissão em uma instituição com capacidade de realizar angioplastia, uso de terapias de reperfusão, qualidade assistencial recebida durante a linha de cuidado, bem como a mortalidade de 30 dias, comparando-se os resultados obtidos pela população usuária do SUS e do sistema privado. Conclusões: O registro VICTIM é um esforço interinstitucional para identificar oportunidades de melhoria na linha de cuidado para IAMCSST de usuários do SUS e do sistema privado. Com isso, espera-se municiar os gestores públicos de informações técnicas que embasem novas políticas de saúde mais eficientes e equânimes.

Abstract Background: The Brazilian Unified Health System (SUS) was created to ensure universal, integral and equitable access to quality healthcare to Brazilians. However, studies scrutinizing the quality of the healthcare provided by the SUS are scarce. This is especially critical for patients with ST-elevation myocardial infarction (STEMI), who depend on healthcare system responsiveness and timely reperfusion to achieve better outcomes. Objective: To describe the methodology of the VICTIM Registry aimed at characterizing and comparing the access to effective therapies and the outcomes of patients with STEMI, who use the SUS and the private healthcare system at hospitals capable of performing angioplasty in Sergipe. In addition, that registry aimed at identifying and measuring possible disparities in the quality of the care provided. Methods and Results: The VICTIM Registry is an observational study, launched in December 2014, being still in the data collection phase, to investigate: the epidemiology of STEMI in Sergipe, the temporal and geographic courses of the patients up to their admission to one of the hospitals capable of performing angioplasty, the reperfusion therapy rates, the quality of the healthcare provided during the event, and the 30-day mortality. It compares the results obtained in the SUS with those of the private healthcare system. Conclusions: The VICTIM Registry is an interinstitutional effort to identify opportunities for healthcare improvement for SUS and private healthcare system patients with STEMI. It is expected to provide healthcare managers with information to support new, more efficient and equitable healthcare policies.

ABSTRACT Stretching for more than 10,000 ha in the Metropolitan Area of São Paulo, southeastern Brazil, Serra da Cantareira comprises the largest native urban rainforest in the World, harboring a rich and diverse Atlantic Forest avifauna. Despite its closeness to major urban areas, few bird surveys have been conducted there. In this article we present an updated compilation of all bird species recorded for Serra da Cantareira, including personal records from the authors. A total of 326 species have been recorded for Serra da Cantareira since 1901; of these, nine have not been sighted there for the last two decades. The number of bird species endemic to the Atlantic Forest is high (80), and seven of its species are globally threatened. According to multivariate analyses the species diversity at Serra da Cantareira is similar to other regions of the Atlantic Forest, such as Carlos Botelho and Intervales state parks, where the vegetation is also ombrophilous dense forest. We discuss local changes in the avifaunal composition over the last decades and suggest the incorporation of large forest remnants to the Cantareira State Park to mitigate the impact of the northern section of Rodoanel Mário Covas, a highway (SP-21) that will soon be operational and will negatively impact the biodiversity of Serra da Cantareira.

Após a descrição no século XIX de duas espécies de beija-flores atualmente alocados no gênero Stephanoxis, ambos os táxons foram considerados subespécies por Peters (1945), sem que o autor fornecesse qualquer justificativa para tal decisão taxonômica. Com base em um expressivo número de exemplares nós reavaliamos a taxonomia e o limite de espécies dos representantes deste gênero, e demonstramos que ambos são mais bem tratados como espécies plenas sob os Conceitos Biológico e Filogenético de Espécie devido aos bem definidos padrões de plumagem e de distribuição geográfica, assim como pela distinta reciprocidade monofilética. Ambos os táxons são separados por cerca de 160 quilômetros entre a Serra do Mar, a leste, e a Serra de Paranapiacaba, a oeste, dentro do Estado de São Paulo. A distribuição das duas espécies de Stephanoxis é congruente com as de outras espécies de aves montanas, o que sugere eventos vicariantes compartilhados durante períodos interglaciais pretéritos.

After the description in the 19th century of two hummingbird species currently allocated to the genus Stephanoxis, Peters (1945) merged both taxa into a single species without providing any rationale. Here we re-evaluate the taxonomy and species limits of the representatives of this genus based on an extensive number of specimens. We demonstrate these taxa are better treated as full species under both the Biological and Phylogenetic Species Concepts due to their well-defined range and plumage patterns and reciprocally diagnosability. They have distinct, allopatric distributions segregated by a 160 km gap between the Serra do Mar, to the east, and Serra de Paranapiacaba, to the west, in the state of São Paulo. Stephanoxis species have ranges which are congruent with other montane bird species’ suggesting shared vicariance events during preterit interglacial periods.

A busca por substratos alternativos, que possam substituir produtos comerciais na produção de mudas de tomate, é de fundamental importância para a redução dos custos nessa fase inicial da cultura. Objetivou-se, com esta pesquisa, avaliar a qualidade de mudas de tomate industrial IPA 6, produzidas com substratos à base de esterco ovino. O experimento foi conduzido em viveiro da Universidade Federal Rural de Pernambuco, Unidade Acadêmica de Serra Talhada, de 16 de fevereiro a 30 de março de 2012. Utilizou-se o delineamento inteiramente casualizado, com quatro repetições. Os tratamentos avaliados foram: T1 - [substrato comercial]; T2 - [esterco ovino + areia (1:1)]; T3 - [esterco ovino + areia (2:1)]; T4 - [esterco ovino + areia (3:1)]; T5 - [esterco ovino + solo (1:1)]; T6 - [esterco ovino + solo (2:1)]; T7 - [esterco ovino + solo (3:1)]; T8 - [esterco ovino + areia + solo (1:1:1)];T9 - [esterco ovino + areia + solo (2:1:1)]; T10 - [esterco ovino + areia + solo (3:1:1)]. Os indicadores de emergência avaliados foram: percentagem, índice de velocidade e tempo médio de emergência. Analisaram-se as seguintes características de desenvolvimento: número de folhas, altura de plântula, diâmetro de caule, comprimento de raízes, massa da matéria seca da parte aérea e das raízes. O substrato comercial proporcionou melhor vigor de mudas de tomate IPA 6. Por outro lado, o uso do esterco ovino mais solo (2:1), para compor substratos alternativos constituiu-se opção viável para a produção de mudas desse cultivar.

The search for alternative substrat that can replace commercial products in the tomato seedlings production is very important to reduce costs at the first stage of such culture. The present study aimed to evaluate the quality of industrial tomato IPA 6 seedlings produced with alternative substrate of sheep manure. The experiment was carried ou at a plant nursery at the Universidade Federal Rural de Pernambuco, in Serra Talhada, Pernambuco State, Brazil, from February 16 to March 30, 2012. The experimental design was a completely randomized design with four replications. The treatments were: T1 - commercial substrate; T2 - sheep manure + sand (1:1); T3 - sheep manure + sand (2:1); T4 - sheep manure + sand (3:1); T5 - sheep manure + soil (1:1); T6 - sheep manure + soil (2:1); T7 - sheep manure + soil (3:1); T8 - sheep manure + sand + soil (1:1:1); T9 - sheep manure + sand + soil (2:1:1); T10 - sheep manure + sand + soil (3:1:1). The emergence indicators were: percentage, speed index and average time of emergence. Regarding the development characteristics of seedlings were analyzed: leaf number, stem diameter, seedling height, root length, shoot dry matter and root dry matter. The commercial substrate provided better vigor of tomato IPA 6 seedlings. Moreover, the use of soil and sheep manure (2:1) to compose alternative substrates consisted of a viable option for seedlings production of this cultivar.

INTRODUÇÃO: Insuficiência renal aguda (IRA) acontece com frequência em pacientes críticos, porém a significância clínica de sua ocorrência não tem sido determinada na insuficiência cardíaca descompensada (ICD). OBJETIVOS: Estudar a ocorrência e valor prognóstico da IRA em pacientes internados por ICD e avaliar comparativamente com aqueles sem a complicação o perfil clínico-laboratorial e a mortalidade intra-hospitalar. MÉTODOS: Estudo prospectivo em 85 pacientes internados em terapia intensiva (UTI) por ICD entre março de 2010 e fevereiro de 2011. Foi feito o diagnóstico de insuficiência cardíaca (IC) conforme critérios de Boston (escala > 8) e exames complementares, e o diagnóstico de IRA utilizando a classificação AKIN. Na análise estatística, utilizaram-se teste t de Student, qui-quadrado e modelo de regressão com múltiplas variáveis, considerando estatisticamente significativo p < 0,05. RESULTADOS: Predominaram homens (55%), valvopatia foi a principal etiologia da IC (42,4%), e má aderência/medicação inadequada foi a principal causa de descompensação (22,4%). IRA ocorreu em 76,5% dos indivíduos (4,7% estágio 1, 32,9% estágio 2 e 38,8% estágio 3 AKIN). Havia mais pacientes com anemia (p = 0,01) e acima de 60 anos (p = 0,02) no grupo com IRA quando comparado ao controle. Todos os pacientes com disfunção renal prévia desenvolveram IRA. Em média, permaneceram internados por 7,7 dias (grupo IRA 8,8 ± 6,6 dias; grupo não IRA 4 ± 1,4 dias; p < 0,01). A mortalidade foi maior no grupo com IRA (p = 0,04), principalmente no estágio 3 (p < 0,01). Identificou-se como preditor independente de IRA o número de dias em UTI (p = 0,02). IRA foi o único preditor independente de mortalidade no grupo (p = 0,05). CONCLUSÃO: IRA ocorre com frequência em ICD, principalmente em estágios AKIN mais avançados, na população renal crônica e idosa, e relaciona-se a maior tempo de internação e mortalidade.

INTRODUCTION: Acute kidney injury (AKI) occurs frequently in critical patients, but its clinical relevance has not been determined in decompensated heart failure (DHF). OBJECTIVES: To study the occurrence and prognostic value of AKI in patients with DHF and to compare the clinical and laboratory characteristics and in-hospital mortality with those without AKI. METHODS: Prospective study of 85 patients hospitalized in intensive care unit (ICU) with DHF from March 2010 to February 2011. Diagnosis of heart failure (HF) was established using the Boston criteria (scale > 8) and additional tests, and AKI was defined using the AKIN classification. Patients data with and without AKI were compared using Student's t-test, chi-squared statistic and multiple logistic regression, considering statistically significant p < 0.05. RESULTS: Most patients were male (55%), valvular disease was the main etiology of HF (42.4%), and inadequate medication was the main cause of decompensation (22.4%). AKI occurred in 76.5% of patients (4.7% stage 1, 32.9% stage 2 and 38.8% stage 3). Patients were more anemic (p = 0.01) and had over 60 years (p = 0.02) in the AKI-group when compared to control. All patients with chronic kidney failure developed AKI. The duration of ICU stay was longer for the AKI group (group AKI 8.8 ± 6.6 days; group non-AKI 4 ± 1.4 days, p < 0.01). In-hospital mortality rate was higher in patients with AKI (p = 0.04), especially in stage 3 (p < 0.01). The duration of ICU stay was an independent predictor of AKI (p = 0.02). Only AKI was considered as independent predictor of mortality in this group (p = 0,05). CONCLUSION: AKI is frequent in DHF, especially in advanced stages, in the elderly and patients with chronic kidney disease, and was associated with longer hospitalization and higher mortality rate.

OBJETIVOS: Verificar a influência da força muscular respiratória pré-operatória na incidência de complicações pulmonares no pós-operatório de cirurgia cardíaca em pacientes com insuficiência cardíaca. MÉTODOS: De março de 2009 a setembro de 2010, 40 pacientes internados no serviço de cardiologia da Fundação de Beneficência Hospital de Cirurgia foram distribuídos em dois grupos, de acordo com os valores da pressão inspiratória máxima avaliada por meio da manovacuometria: Grupo A (n=21), composto de pacientes que apresentaram força muscular respiratória normal; e grupo B (n=19), pacientes com redução da força. Após a avaliação pré operatória, todos foram submetidos ao procedimento cirúrgico e acompanhados até o momento da alta hospitalar pelo mesmo pesquisador, que anotava na ficha de coleta de dados sua evolução, especialmente quanto à presença de complicações pulmonares no pós-operatório, que foi dividida em geral e específica. RESULTADOS: Dezenove por cento dos pacientes do grupo A e 31,6% dos pacientes do grupo B apresentaram complicações pulmonares gerais, sendo esta diferença não significativa estatisticamente (P=0,29). Quanto à presença de complicações específicas, o grupo A teve 14,3% e o grupo B 10,5% (P= 0,55). Também não houve diferença quanto aos dias de internação em UTI e total (UTI + enfermaria) entre os grupos. CONCLUSÃO: Nesse trabalho, a disfunção muscular respiratória no pré-operatório de cirurgia cardíaca não foi considerada um fator de risco para desenvolvimento de complicações pulmonares no pós-operatório

OBJECTIVE: To investigate the influence of preoperative respiratory muscle strength in postoperative pulmonary complications in patients with heart failure undergoing cardiac surgery. METHODS: From March 2009 to September 2010, 40 patients admitted to the cardiology service of the Fundação de Beneficência Hospital de Cirurgia were divided into two groups according to the values of maximal inspiratory pressure measured by manometer: Group A (n = 21), composed of patients with normal respiratory muscle strength, and Group B (n = 19), patients with reduced strength. After pre-operative evaluation, all patients underwent the surgical procedure and followed until hospital discharge by the same researcher, who recorded on data collection especially its evolution for the presence of pulmonary complications after surgery, which was divided general and specific. RESULTS: 19% of patients in group A and 31.6% of patients in group B had pulmonary complications overall, this difference was not statistically significant (P = 0.29). Regarding the presence of specific complications, group A was 14.3% and 10.5% group B (P = 0.55). There was also no difference in the days of ICU stay and total (ICU + ward) between groups. CONCLUSION: In this study, preoperative respiratory muscle dysfunction does not seem to influence the evolution of heart failure patients for the presence of pulmonary complications after cardiac surgery

Abstract: Pt En | Text: Pt En | PDF: Pt | PDF: En

Inventários e estudos faunísticos detalhados sobre vertebrados são uma das fontes mais relevantes de dados para interpretações de padrões detalhados de diversidade biológica. Dados básicos e de boa qualidade sobre faunística são ainda mais urgentes em regiões pouco estudadas e sob intensa ameaça antrópica, tais como a região do Cerrado, um dos 34 hotspots globais para a conservação da biodiversidade. Apresentamos aqui uma síntese dos resultados dos inventários de vertebrados na Estação Ecológica Serra Geral do Tocantins (~716.000 ha), a segunda maior unidade de conservação em todo o Cerrado. Foram registradas 450 espécies de vertebrados na EESGT e entorno imediato, incluindo 17 espécies ameaçadas, 50 espécies endêmicas do Cerrado e 11 espécies com distribuição potencialmente restrita. Do total de espécies amostradas, 180 são novos registros para a região do Jalapão. Ao menos 12 espécies amostradas foram consideradas potenciais espécies novas, das quais quatro foram descritas recentemente, a partir do material obtido no inventário. Os resultados evidenciam que a EESGT é uma das mais importantes áreas protegidas no Brasil central, contribuindo para a persistência de espécies ameaçadas, dependentes dos últimos grandes blocos contínuos de vegetação nativa de Cerrado. Nossos resultados indicam ainda que a conservação da EESGT e suas principais subunidades é crucial para a representatividade do sistema de áreas protegidas do Cerrado, protegendo potenciais endemismos restritos que aliam alta vulnerabilidade intrínseca e valor como indicadores de padrões e processos biogeográficos formadores da rica e cada vez mais ameaçada fauna Neotropical.

Basic taxonomic and distributional data on vertebrates are one of the most useful and reliable sources of information for conservation planning. Biological data are even more relevant in rich and highly threatened regions such as the Brazilian Cerrado, one of the least studied global biodiversity hotspots. Herein we provide a summary of the results of a vertebrate survey at Estação Ecológica Serra Geral do Tocantins (~716.000 ha), the second largest protected area in the Cerrado region. We recorded 450 species in EESGT and surroundings, including 17 threatened species, 50 Cerrado endemics and 11 potential restricted-range species. Our results also added 180 new vertebrate records for the Jalapão region. At least 12 species were considered potential undescribed taxa; four of these were recently described based on specimens obtained in the present study. Our results indicate that EESGT is among the most biologically relevant protected areas in the Cerrado. Proper management will favor the persistence of threatened vertebrates dependent on the last remaining large blocks of pristine Cerrado savannas. Moreover, EESGT and its major biological subunits contribute decisively to the representativeness of the reserve system in the Cerrado, conserving presumed narrow endemics with high intrinsic vulnerability and high potential value as indicators of biogeographic processes of diversification in rich and complex Neotropical biotas.

A Estação Ecológica Serra Geral do Tocantins (EESGT) é uma das maiores Unidades de Conservação dentro do Bioma Cerrado. A avifauna desta UC foi inventariada entre os dias 25 de janeiro e 15 de fevereiro de 2008. Durante esse trabalho buscou-se amostrar os diferentes hábitats encontrados na EESGT, bem como algumas localidades no entorno. Além de registros auditivos e visuais foram utilizadas redes-de-neblina e armas de fogo para coletas de material testemunho, que se encontra depositado na coleção ornitológica do Museu de Zoologia da Universidade de São Paulo (MZUSP). Os resultados obtidos foram comparados com os dados disponíveis para outras unidades de conservação presentes na região. Foram registradas 254 espécies de aves, incluindo 11 endêmicas do Cerrado e outras três ameaçadas de extinção (Taoniscus nanus, Anodorhynchus hyacinthinus e Procnias averano). Três indivíduos pertencentes ao gênero Picumnus foram coletados; estes apresentam um distinto padrão de plumagem e de vocalização, podendo representar um táxon ainda não descrito.

The Estação Ecológica Serra Geral do Tocantins is one of the largest conservation units in Cerrado Biome. The avifauna of this locality was studied from January 25 to 15 February, 2008. We attempted to sample the different habitats found both within the EESGT as in its surroundings. In addition to audio and visual records, mist nets and shotguns were used to collect testimony material, which was deposited in the ornithological collection of the Museu de Zoologia da Universidade de São Paulo (MZUSP). The results were compared with data available from other conservation units nearby the EESGT. We recorded 254 bird species; among these 11 were considered endemic to the Cerrado region and other three considered threatened (Taoniscus nanus, Anodorhynchus hyacinthinus and Procnias averano). Three individuals belonging to the Picumnus genus also were collected; they presented unusual plumage and vocalization patterns, which suggests an undescribed taxon.
