The Atlantic Forest in southern Bahia State, Brazil, has high levels of diversity and vascular plant endemism. There have been few floristic surveys of the mountain forests there, however, especially those focusing on herbs and canopy plants, with studies of Atlantic Forest epiphytes having been limited to the southern and southeastern region of that country. The present study therefore surveyed the epiphytic angiosperms in the Serra das Lontras National Park (SLNP), the distribution of their species among genera and families, and their biogeographical patterns. Fieldwork was performed between February 2011 and March 2012. Collections were made along roads and trails and phorophytes were occasionally climbed and fallen trees and branches examined in order...

Serra da Pedra Branca (SPB) is a mountain range located in the Southwestern portion of the state Minas Gerais, in the municipality of Caldas (21°58′-21°55′S, 46°24′-46°22′W). It is a striking feature in the landscape, between 1100 and 1780 m.s.m., in a region that is part of the Atlantic Forest Domain and is considered as a priority area for conservation of the flora in Minas Gerais state. The vegetation is composed by a mosaic of “campo de altitude” (which occupy the greatest extension in the area), Seasonal Semidecidual Montane Forest, Dense Ombrophilous High-Montane Forest and Mixed Ombrophilous Forest. The aims of this study was the elaboration of a floristic survey of SPB added to the specimens collected by Anders Fredrik Regnell in the nineteenth...

A região da Serra Negra constitui um importante remanescente de floresta atlântica situado no sul da Zona da Mata mineira, na Serra da Mantiqueira, composta por um mosaico de campos rupestres (nos afloramentos de quartzito) a arbustais nebulares, florestas estacionais semideciduifólias a perenifólias e florestas nebulares, de ambientes inferomontanos a superomontanos ripícolas a interfluviais. A área de estudo é um fragmento de floresta de grota (floresta perenifólia ripícola), de aproximadamente 0,9 ha, situada no Cânion do Ribeirão do Funil, na Vila do Funil, município de Rio Preto, localizada no sul da Serra Negra. O presente trabalho foi realizado entre os anos de 2004 e 2009 e teve como objetivos o conhecimento da flora vascular não-arbórea, a...

Neste estudo, foi realizado o levantamento das Orchidaceae das Serras Negra e do Funil (SN/SF), Zona da Mata de Minas Gerais, e uma análise da similaridade florística dessa família entre 29 áreas campestres e florestais do Brasil. Para tal análise, utilizou-se o algoritmo UPGMA, coeficiente de SØrensen, e 5.000 replicações de bootstrap. A análise de agrupamento revelou baixos índices de similaridade, exceto para os grupos Serra Negra + Parque Estadual do Ibitipoca e Parque Estadual da Ilha do Cardoso + Estação Ecológica Juréia-Itatins. Os resultados sugerem que a região das SN/SF represente um corredor florístico entre localidades na Serra da Mantiqueira (Parque Nacional do Itatiaia) e Serra do Mar (Reserva Biológica de Macaé de Cima). Foi observado o...

O Parque Estadual de Ibitipoca (PEIB) está situado no sudeste do estado de Minas Gerais, entre os municípios de Santa Rita de Ibitipoca e Lima Duarte, a 21º40'-21º44'S e 43º52'-43º55'W. Apresenta em sua área um mosaico de formações vegetais, das quais o campo rupestre ocupa a maior extensão, sendo também encontradas em seus domínios diversas formações florestais. O presente trabalho teve como objetivo o levantamento das espécies de Orchidaceae ocorrentes no PEIB. Foram registrados 118 táxons distribuídos em 47 gêneros. Os gêneros mais numerosos são Pleurothallis sensu lato (13 spp.), Oncidium (12 spp. e um possível híbrido), Epidendrum (10 spp.) e Maxillaria (9 spp.). O estudo da distribuição geográfica dos táxons revelou quatro novos registros para a...

ABSTRACT Palms are most diverse in warm and humid regions near the equator. Though palms remain relatively well conserved, they are under increasing pressure from deforestation. Here, we analyze patterns of palm species richness relative to latitudinal gradient, sampling effort, and deforestation in the Amazon, and compare patterns of richness and floristic similarity among Amazonian sub-regions. We built a database of 17,310 records for 177 species. The areas with the greatest richness were in the western, central and northeastern Amazon, principally at latitudes 0-5ºS. Species richness and the number of records were highly correlated (R2=0.76, P<0.005). The highest rates of deforestation (>2000 km2) were found in the southern and eastern Amazon of...

Abstract This study aimed to analyze patterns of richness and distribution of Cactaceae in the Serra da Mantiqueira (SM), a mountain range located in Southeast Brazil, and assess its conservation status. We compiled distribution data from the literature and 16 herbaria and plotted it on a map divided into grid squares of 0.5°. Richness, collection effort and similarity among grid squares were analyzed for the 33 taxa recorded in SM (five of which are endemic). Maciço do Itatiaia (in southern SM), Serra do Brigadeiro and Serra do Caparaó (in northern SM) are the richest areas. Collection effort and richness were correlated (R²=0.75). Similarity analysis revealed five clusters, one of which is composed of high elevation areas with a vegetation mosaic; the...

Abstract: This study was developed in Ibitipoca State Park (ISP), a mountainous massif that stands out in the Serra da Mantiqueira, in the Southeastern Region of Brazil. The vegetation is represented by a phytophysiognomic mosaic where areas of campos rupestres interspersed with cloud dwarf forests predominate, at altitudes of 1100 to 1700 m.s.m. The cloud dwarf forests exist in narrow altitude belts on the mountain peaks, immersed in a layer of clouds. They form a peculiar landscape high in the mountains by the short stature of the arboreal elements and richness of lichens and bryophytes, which develop under constant condensation of humidity, low temperatures, and frequent winds. The objective of the present work was to determine the floristic composition...

Pseudolaelia is a genus endemic to eastern Brazil. The species are often epiphytes on Velloziaceae or are saxicolous, predominantly on granitic and gneissic outcrops (inselbergs) in the Atlantic Forest and, less often, in the campos rupestres (dry, rocky grasslands) of the cerrado (savanna) and caatinga (shrublands). The genus is characterized by homoblastic pseudobulbs, long rhizomes, long and usually slender inflorescences, racemes or panicles, bearing pink, yellow or whitish flowers, labellum often 3-lobed, with simple, fimbriate or erose margin, semi-cylindrical or claviform column, cuniculus present. Twelve species are recognized; seven binomials are placed in synonymy. Of those seven, three are considered illegitimate because, contrary to the...

ABSTRACT Only a few studies regarding vascular epiphytes have been conducted in mixed ombrophilous forests (MOF) in Serra da Mantiqueira, a mountainous environment in the Brazilian Atlantic Forest, where the relationships of epiphytic flora with other physiognomies are unknown. This study aimed to survey the epiphytes of a MOF remnant located in Serra da Mantiqueira, and to analyze the floristic relationships with ombrophilous forests of the Southern and Southeastern regions of Brazil. The checklist was compared with 51 other areas composed of ombrophilous forests and/or ecotones with other physiognomies using UPGMA (with Sørensen index), and canonical correspondence analysis (CCA). We recorded 138 species, and Orchidaceae and Polypodiaceae were the...
