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three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data.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

Representaciones Sociales, Género & Salud en Brasil: una revisión bibliográfica.

O objetivo dessa revisão bibliográfica é fornecer um primeiro panorama das investigações realizadas em nosso país que procuraram, a partir da Teoria das Representações Sociais, considerar aspectos relativos às relações de gênero no campo da saúde. Foram agrupados, em 2009, todos os 259 itens disponíveis em três bibliotecas eletrônicas online (Pepsic, Scielo e Biblioteca Virtual de Saúde - BVS) a partir da consulta pelos termos “Representação Social” e “Representações Sociais”. Também foram consultados 716 trabalhos completos publicados nos Anais de três Conferências Brasileiras sobre Representações Sociais (Rio de Janeiro, 2003; João Pessoa, 2005; Brasília, 2007). Identificamos, nesse conjunto, 34 relatos de investigações realizadas no Brasil que procuraram contemplar a interface entre gênero e saúde, sob o enfoque da Teoria das Representações Sociais. Procuraremos aqui apresentar de maneira geral esse conjunto de trabalhos, considerando o número e as características das fontes de informação acessadas, os procedimentos de coleta de dados e os métodos de análise utilizados nas investigações. Também apresentaremos informações sobre as áreas dos periódicos nos quais foram publicados os artigos selecionados, bem como a área de origem dos autores de todos os 34 itens do corpus. Posteriormente, as características gerais apresentadas serão comparadas, em termos de proximidade ou de especificidade, com informações provenientes de levantamentos já realizados no país sobre a produção em Representações Sociais

Characterisation of microbial attack on archaeological bone

As part of an EU funded project to investigate the factors influencing bone preservation in the archaeological record, more than 250 bones from 41 archaeological sites in five countries spanning four climatic regions were studied for diagenetic alteration. Sites were selected to cover a range of environmental conditions and archaeological contexts. Microscopic and physical (mercury intrusion porosimetry) analyses of these bones revealed that the majority (68%) had suffered microbial attack. Furthermore, significant differences were found between animal and human bone in both the state of preservation and the type of microbial attack present. These differences in preservation might result from differences in early taphonomy of the bones. © 2003 Elsevier Science Ltd. All rights reserved
