    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three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data.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: verificar a prática do uso de chupetas e sua relação com o desmame precoce em crianças nascidas em um Hospital Amigo da Criança. Método: estudo de coorte, longitudinal, envolvendo 250 bebês sadios nascidos no Hospital de Clínicas de Porto Alegre, com peso de nascimento >2.500 g, não gemelares, com o aleitamento materno iniciado, de famílias residentes em Porto Alegre. Os dados foram obtidos mediante entrevista com as mães na maternidade e nas suas casas, no final do primeiro e do sexto mês do bebê e, por telefone, no segundo e quarto mês. Foram construídas curvas de sobrevida para comparar as prevalências de aleitamento materno e aleitamento materno exclusivo nos primeiros seis meses, entre as crianças usuárias e não usuárias de chupetas. Resultados: das 237 crianças localizadas no final do primeiro mês de vida, 61,6% usavam chupeta, a maioria desde a primeira semana de vida. O uso de chupeta foi mais freqüente entre as crianças do sexo masculino e entre as com mães com baixa escolaridade; entre as crianças amamentadas com um mês, o uso de chupeta foi observado com mais freqüência naquelas não amamentadas exclusivamente. A incidência de desmame, entre o primeiro e sexto mês, nas crianças ainda amamentadas no final do primeiro mês, foi de 22,4% para as crianças não usuárias de chupeta, e de 50,8% para as usuárias (p<0,001). Quase 2/3 das usuárias de chupeta deixaram de ser amamentadas exclusivamente até o final do segundo mês; entre as não usuárias, o índice foi de 45% (p<0,001). Conclusão: a prática do uso de chupeta é muito arraigada na nossa cultura, mesmo em população orientada para evitá-la. A associação entre uso de chupeta e menor duração do aleitamento materno e aleitamento materno exclusivo foi confirmada nesta população.Objective: to assess the use of pacifiers and its relationship with early weaning among children born at a Child-Friendly Hospital. Method: a cohort study was carried out with 250 healthy singleton babies, with birthweight > 2,500 g, and with ongoing breastfeeding, born at Hospital de Clínicas de Porto Alegre. All mothers lived in Porto Alegre. Data were collected through interviews with the mothers, both at the maternity ward and at their homes, at the end of the first and sixth month of life; and over the phone, in the second and fourth months. Survival curves were built to compare the prevalence of breastfeeding and exclusive breastfeeding during the first six months of life among pacifier and non-pacifier users. Results: among the 237 newborns contacted in the first month of life, 61.6% had been using pacifiers, most of them since the first week of life. The use of pacifiers was more frequent among male newborns and among those with poorly educated mothers; among babies who were being breastfed, the use of pacifiers was more commonly observed among non-exclusively breastfed ones. Considering the babies who were still being breastfed by the end of the first month of life, the incidence of weaning between months 1 and 6 was 22.4% for non-pacifier users and 50.8% for pacifier users (p<0.001). Almost 2/3 of pacifier users stopped being exclusively breastfed before the end of the second month; among non-pacifier users, this rate was 45% (p<0.001). Conclusion: the use of pacifiers is deeply rooted in our culture, even in a population oriented towards avoiding it. The association between pacifier use and shorter duration of breastfeeding and exclusive breastfeeding was confirmed in this population
