1. DIFFERENTIAL RESPONSE OF EPIPHYTIC LICHEN TAXA TO AGRICULTURAL LAND USE IN A FRAGMENTED FOREST IN CENTRAL ARGENTINA
ABSTRACT The seasonally dry subtropical forest, especially the Espinal forest in central Argentina (one of the most fragmented ecoregions), is affected by intensive agricultural activity. These activities are the main anthropogenic sources of atmospheric nitrogen compounds and their effects on lichens have been extensively studied, making them excellent ecol

2. Variation in root morphology of epiphytic orchids along small-scale and large-scale moisture gradients
ABSTRACT Root morphology is expected to respond to environmental conditions. Two earlier studies reported predictable changes in the structure of the velamen radicum (common in monocotyledons) along rainfall gradients, which was expected from its assumed role in plant-water-relations. The present study expanded on this idea by analysing nine root traits that

3. Environmental factors affect population structure of tree ferns in the Brazilian subtropical Atlantic Forest
ABSTRACT Tree ferns are important elements of tropical forests, mainly because they are common and provide microhabitats for epiphytic plants. Due to their ecological importance, the aim of this study was to evaluate population structure, distribution, and influence of environmental variables on tree ferns in the state of Santa Catarina, southern Brazil. All

4. Cultivable bacterial diversity associated with bromeliad roots from ironstone outcrops in central Brazil
Resumo Estudos sobre a diversidade bacteriana associada a plantas silvestres são raros, especialmente naqueles que crescem em associação com bromélias. No presente estudo, isolamos e identificamos bactérias epífitas e endofíticas das raízes das bromélias Dyckia excelsa, D. leptostachya e Deuterocohnia meziana ocorrentes nas “cangas” no Pantanal

5. Adaptive morphoanatomy and ecophysiology of Billbergia euphemiae, a hemiepiphyte Bromeliaceae
Resumo Habitats com pressões seletivas diferentes exercem pressões adaptativas que podem levar indivíduos de uma mesma espécie a apresentar diferentes estratégias de vida para sua sobrevivência. O objetivo desse estudo foi analisar características funcionais para identificação de estratégias ecológicas adaptativas relacionadas às fases de vida te

6. Diversity of Endophytic and Epiphytic Bacteria From Sugarcane in Khuzestan, Iran
Abstract Diverse microorganisms are living as endophytes in plant tissues and as epiphytes on plant surfaces in nature. Commercial formulations of bacteria antagonist to plant pathogenic microbes and ice nucleation active bacteria have been utilized as an environmentally safe method to manage plant disease and to prevent frost damage respectively. Bacteria w

10. What are the species of phorophytes of Vanilla palmarum (Orchidaceae) in Brazil? An assessment of emblematic specificity with palm tree species
Resumo Vanilla palmarum (Orchidaceae) é uma holoepífita obrigatória, amplamente distribuída na América do Sul, e apresenta uma emblemática especificidade com palmeiras. A interação epífita-forófitos foi examinada através da análise de espécimes disponíveis na base de dados do Centro de Referência em Informação Ambiental e em herbários brasi

11. Epiphyte-phorophyte relationships: assessing the differences between Seasonal Semideciduous and Swamp Forests in Southeastern Brazil1
RESUMO As epífitas vasculares são responsáveis por uma parcela considerável da biodiversidade tropical; no entanto, suas relações com os forófitos entre diferentes tipos de vegetação em que ocorrem ainda são pouco compreendidas. Neste trabalho, objetivamos avaliar a presença, a abundância, a distribuição vertical e a categoria ecológica (holoe

12. Association of Fusarium and Phomopsis with Peroba Rosa Seeds
ABSTRACT Peroba rosa (Aspidosperma polyneuron) is a native forest species endangered due to intense predatory exploitation. The objective of this study was to evaluate the association and fungi transmission in peroba rosa seeds from four regions of Paraná. Germination and vigor were evaluated using the paper roll method. Sanitary analysis consisted of the d
