ATLANTIC EPIPHYTES: a data set of vascular and non-vascular epiphyte plants and lichens from the Atlantic Forest
Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non-vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non-vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non-vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest.

Modernidade republicana e diocesanização do catolicismo no Brasil: as relações entre Estado e Igreja na Primeira República (1889-1930)
Asymptomatic infection in family contacts of patients with human visceral leishmaniasis in Três Lagoas, Mato Grosso do Sul State, Brazil Infecção assintomática em contactantes de pacientes com leishmaniose visceral humana em Três Lagoas, Mato Grosso do Sul, Brasil
The Brazilian city of Três Lagoas, Mato Grosso do Sul State, has experienced an urban outbreak of visceral leishmaniasis since 2000. In 2002, due to the increase in the number of cases, 46 families with cases of visceral leishmaniasis were studied to verify the prevalence of asymptomatic infection in household contacts. Indirect immunofluorescence and ELISA showed a 36.4% positive infection rate. There were no cases of symptomatic disease among these contacts. There was no statistically significant difference in gender or age. Median age was 21 years, and the 10-19-year age bracket was the most heavily affected (23%). As for family characteristics, no differences were observed in schooling or family income; most families (58.7%) owned their homes, which were built of masonry (97.8%) and had adequate infrastructure. All the families reported what were probably phlebotomine sand flies in the peridomicile. In conclusion, asymptomatic visceral leishmaniasis infection is frequent and occurs in both males and females, regardless of age.<br>O Município de Três Lagoas, Mato Grosso do Sul, Brasil, foi alvo de uma epidemia de leishmaniose visceral a partir de 2000. Em 2002, devido ao incremento de casos, estudou-se 46 famílias que apresentavam um caso de doença para verificar-se o percentual de positividade de infecção assintomática por leishmaniose visceral em contactantes. Encontrou-se 36,4% de positividade pelos testes sorológicos Reação de Imunofluorescência Indireta e/ou imunoenzimático ELISA, sem diferença estatisticamente significativa quanto ao sexo e faixa etária. A mediana de idade foi de 21 anos, sendo a faixa etária mais acometida de 10 a 19 anos (23%). Quanto às características familiares não observaram-se diferenças quanto ao nível de instrução e renda familiar; a moradia, em sua maioria, era própria (58,7%), em alvenaria (97,8%), com infra-estrutura adequada. Todas as famílias relataram a presença de provável flebotomíneo no peridomicílio. Conclui-se que a infecção assintomática por leishmaniose visceral é freqüente, ocorrendo em homens e mulheres, independente de faixa etária
Absorção de nutrientes e resposta à adubação em linhagens de tomateiro Nutrient uptake and response to fertilization of tomato inbred lines
Vinte e nove linhagens de tomateiro rasteiro foram avaliadas quanto à eficiência de absorção de nutrientes e resposta à adubação, em dois ensaios, no ano de 2006, na Embrapa Hortaliças. No primeiro ensaio aplicou-se 1/3 da dosagem de fertilizante utilizada no segundo. O delineamento experimental foi inteiramente casualizado, com três repetições. As linhagens foram classificadas quanto à eficiência na absorção de nutrientes e reposta à adubação baseando-se nos incrementos de índice DRIS e nos incrementos de produtividade. Os valores críticos para eficiência na absorção e resposta à adubação foram as médias de incremento de índice DRIS e produtividade, respectivamente. As linhagens diferenciaram-se quanto à eficiência na absorção dos nutrientes e quanto à resposta à adubação. Foram consideradas responsivas à adubação e eficientes na absorção de nutrientes as linhagens 03, 04, 05, 09 e 22, para o N; 03, 04, 09, 13, 15 e 29, para o P; 03, 05, 10, 21, 22, 25 e 27, para o K; 05, 10, 21, 22, 25, 27 e 29, para o Ca; 04, 13, 15, 27 e 29, para o S e B; e 03, 05, 09, 10 e 27, para o Cu. As linhagens com os melhores desempenhos foram a 27, na absorção dos nutrientes, e 03, 04, 05 e 29, na responsividade à adubação.<br>Twenty nine processing tomato inbred lines were evaluated for their efficiency in nutrient uptake and in their response to fertilization. Two field assays were carried out at Embrapa Hortaliças, Brazil, with distinct fertilization dosages in 2006. In the first assay 1/3 of the total fertilization was applied when compared with the second assay. The experiments were conducted using a completely randomized design with three replications. The criteria to rank the inbred lines in both assays were the DRIS (Diagnosis and Recommendation Integrated System) index value and fruit yield. The critical values in order to distinguish efficient versus non-efficient as well as responsive versus non-responsive inbred lines were the average increase in both DRIS index value and fruit yield. Differences were detected among inbred lines for the uptake efficiency for all nutrients and for response to fertilization. The inbred lines 03, 40, 09 and 22 were classified as responsive to fertilization and efficient in N uptake; the lines 03, 04, 09, 13, 15 and 29 were for P; 03, 05, 10, 21, 22, 25 and 27 for K, 05, 10, 21, 22, 25, 27 and 29 for Ca; 04, 13, 15, 27 and 29 for S and B; 03, 05, 09, 10 and 27 for Cu. The inbred lines with the best performance were 27 in relation to nutrient absorption, and the lines 03, 04, 05 and 29 in relation to fertilization response
