    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three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data.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.

    OBJETIVO: Determinar a sensibilidade, a especificidade e o risco de eventos cardiovasculares em pacientes com Duke-escore (DE) baixo, intermediário e alto risco, em comparação com a presença (ou não) de defeitos de perfusão à cintilografia do miocárdio. MÉTODOS: Estudo prospectivo, consecutivo, com 173 pacientes com 2 ou mais fatores de risco para doença arterial coronariana (DAC), que foram submetidos à cintilografia de perfusão do miocárdio com tetrofosmin marcado com tecnécio-Tc 99m (CPM) e ao teste ergométrico (aplicando-se o DE), de um bairro de Curitiba, entre janeiro de 2003 a fevereiro de 2004. Os pacientes tiveram seguimento de 13±1 meses e 162 completaram o acompanhamento. Foi avaliada a presença de morte, angina, infarto agudo do miocárdio, angioplastia coronariana e revascularização do miocárdio. RESULTADOS: A média do DE dos pacientes que apresentaram eventos (18) foi de -0,27 (95% IC= -3,97 a +3,91) e daqueles livres de eventos (144) foi de +4,92 (95% IC= +4,03 a +5,81), com p<0,00069. A sensibilidade do DE foi de 72,22% e da CPM foi de 77,78%, sem diferença estatística, com p=0,21. A especificidade do DE foi de 54,17% e a da CPM foi de 88,19%, com p<0,0001. A curva de Kaplan-Meier demonstrou que 94% dos pacientes com DE baixo risco permaneceram livres de eventos em 01 ano. Em contraste, todos os de alto risco apresentaram eventos no mesmo período. Os que apresentaram DE de intermediário risco apresentaram 15% de eventos em 01 ano. CONCLUSÃO: O DE foi tão sensível quanto CPM em determinar o risco para DAC em um ano. Os pacientes com DE <-0,27 tiveram maior risco de eventos cardíacos.<br>OBJECTIVE: The purpose was to determine the sensitivity, the specificity and a year-long risk of subsequent cardiovascular events in patients with low, intermediate and high risk prognostic Duke treadmill score (DTS) in comparison with the presence (or not) of the myocardial perfusion defects on radionuclide images. METHODS: A prospective study, with 173 consecutive patients with 02 or more risk factors to coronary artery disease (CAD), who underwent to exercise single photon - emission computed tomographic myocardial perfusion images using technetium-99m tetrophosmin (SPECT) and treadmill test (with DTS), from one neighbourhood of Curitiba city, between January 2003 and February 2004, were followed up for cardiac-cause mortality and major cardiac events. Follow-up was performed in 13± 1 months and in 162 patients was complete. RESULTS: The DTS mean those patients with cardiac event (18) over a year was -0.27 (95% CI= -3.97 to +3.91) and those free cardiac event patients (144) was +4.92 (95% CI= +4.03 to +5.81), with p<0.00069. The DTS sensitivity was 72.22% and the SPECT sensitivity was 77.78%, with no significant difference p=0.21. The DTS specificity was 54.17% and the SPECT specificity was 88.19%, with p<0.0001. The cumulative proportion free-events (Kaplan-Meier) curves demonstrated that 94% those patients with low-risk DTS remained free-cardiac events. In contrast, all high-risk DTS had adverse cardiac events. Those patients with intermediate-risk DTS had 15% of cardiac event over a year. CONCLUSIONS: The DTS was as sensitivity as SPECT in determine a year risk for CAD. Those patients with DTS <-0.27 had high-risk cardiac event
