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three main sources provided by the authors: published sources (comprising peer‐reviewed articles, books, and theses), unpublished data, and herbarium data.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

The genus Crossodactylodes comprises three species of Atlantic Rainforest endemic frogs strictly dependent on bromeliads where they spend their entire life cycle. The current geographic distribution of the genus covers highland areas of Atlantic Rainforest in the States of Rio de Janeiro and Espírito Santo, Southeastern Brazil. We describe a new species of the genus from Parque Estadual do Pico do Itambé, at Santo Antônio do Itambé municipality, State of Minas Gerais, Southeastern Brazil. Crossodactylodes itambe sp. nov. is characterized by the following combination of traits: male SVL 16.2 ± 1.3 (14.0-17.6 mm, n = 10), female SVL 16.2 ± 1.0 (13.5-18.0 mm, n = 15); snout short, rounded in dorsal view, sloping in lateral view; absence of vocal sac and vocal slits in males; absence of vomerine teeth; males with upper arms and forearms hypertrophied; cloacal flap prominent, simple; dorsal skin coarsely granular. The new species inhabits rupicolous bromeliads in open areas of rocky fields, and is recorded in altitudes between 1836 and 2062 m above sea level. This record extends the genus distribution for about 325 km northwest from where it was known. Crossodactylodes sp. nov. is the only species of the genus that occurs in open field habitats (campos rupestres), in very high altitudes of a non-costal mountain range (the Espinhaço Range).
-(Diversity, vertical structure and floristic relationships of vascular epiphytes in an urban remnant of the Brazilian Atlantic Forest). This study was conducted in a fragment of montane seasonal semi-deciduous forest (Minas Gerais State) with a history of anthropogenic disturbance. Our goals were to characterise the composition, structure and floristic diversity of vascular epiphytes and to investigate the floristic similarities of the community with other areas of urban seasonal forests in Brazil. We sampled 61 phorophytes with 47 epiphytic species. The richest families were Bromeliaceae (seven) and Polypodiaceae (seven). The most common ecological category was accidental holoepiphytes with 21 speciesan unprecedented result for the Neotropical region. The Shannon index was 2.95 and the Pielou evenness index 0.77, showing a relatively high diversity with a few dominant species and numerous rare species. Similarity analyses showed a longitudinal gradient and strong influence of the distance from the ocean on floristic relationships as well as influence of dense ombrophilous forests on the composition of the vascular epiphytes of the surveyed area. Keywords: accidental holoepiphytes, biodiversity hotspot, multivariate analyses, taxonomic diversity, urban forest RESUMO -(Diversidade, estrutura vertical e relações florísticas de epífitas vasculares em um remanescente urbano da Floresta Atlântica brasileira). Este estudo foi realizado em um fragmento de floresta estacional semidecidual montana (Minas Gerais) com histórico de perturbação antrópica. Os objetivos foram caracterizar a composição, estrutura e diversidade florística das epífitas vasculares e investigar a similaridade florística da comunidade com outras áreas de florestas estacionais urbanas no Brasil. Foram amostrados 61 forófitos e registradas 47 espécies de epífitas. As famílias mais ricas foram Bromeliaceae (sete) e Polypodiaceae (sete). A categoria ecológica mais comum foi a de holoepífitas acidentais com 21 espécies -um resultado inédito na Região Neotropical. O índice de Shannon foi 2,95 e o índice de uniformidade de Pielou foi 0,77, mostrando diversidade relativamente alta com certa dominância de poucas espécies, enquanto as espécies raras foram numerosas. Análises de similaridade mostraram gradiente longitudinal e forte influência da distância do oceano sobre as relações florísticas, assim como influência das florestas ombrófilas densas sobre a composição das epífitas vasculares na área estudada. Palavras-chave: análises multivariadas, diversidade taxonômica, floresta urbana, holoepífitas acidentais, "hotspot" de biodiversidade
Data resulting from species inventories shed light on the richness and distribution of various groups. In Minas Gerais, work on inventory and distribution of the oligochaetes of lotic environments in preserved areas are non-existent. Therefore, this study aimed to inventory the limnic oligochaetes fauna of first-order streams located in four preserved areas, to expand knowledge of the ecology and distribution of this group. In total, 19 taxa were inventoried, belonging to the families Naididae and Enchytraeidae and the superorder Megadrili (earthworms), with the genus Pristina having the largest number of species. The number of species found in this investigation corresponds to 22% of oligochaetes species recorded in Brazilian aquatic environments. The results obtained add important knowledge of the distribution of some oligochaetes species in Brazil, represent the first records of species for the four preserved areas studied and confirm the first occurrence of various species in the state.

Inventário e distribuição de Oligochaeta (Annelida,Clitellata) em córregos de primeira ordem localizados em áreas preservadas do estado de Minas Gerais, Brasil. Biota Neotrop. 13(1): http://www.biotaneotropica.org.br/v13n1/pt/abstract?inventory+bn02313012013Resumo: Os dados resultantes de um levantamento fornecem informações sobre a riqueza e distribuição de diversos grupos. Em Minas Gerais, trabalhos sobre inventário e distribuição de oligoquetas de ambientes lóticos em áreas preservadas são inexistentes. Dessa forma, este estudo objetivou inventariar a fauna de oligoquetas límnicos de córregos de primeira ordem localizados em quatro áreas preservadas, visando ampliar as informações sobre ecologia e distribuição deste grupo. Foram inventariados 19 taxa pertencentes às famílias Naididae, Enchytraeidae e à superordem Megadrili, sendo o gênero Pristina o de maior número de espécies. O número de espécies encontradas neste trabalho corresponde a 22% das espécies de oligoquetas registrados em ambientes aquáticos brasileiros. Os resultados obtidos ampliam o conhecimento sobre a distribuição de algumas espécies de oligoquetas no Brasil, representam os primeiros registros de espécies para as quatro áreas preservadas estudadas e confirmam a primeira ocorrência de várias espécies no Estado. Palavras-chave : biodiversidade, Campos Rupestres, Mata Atlântica, Naididae, folhiço, oligoquetas, Enchytraeidae. Martins et al. ( , 2011 and Suriani-Affonso et al. (2011), the number in the state has increased to 23. The true number is probably even higher, because ecological studies often record new species not considered in official records. In this context, the present study aimed to inventory the limnic oligochaete fauna in first-order streams in preserved areas, to expand the information about the ecology and distribution of this group.
