1. Predicting the potential distribution of aquatic herbaceous plants in oligotrophic Central Amazonian wetland ecosystems
ABSTRACT Aquatic herbaceous plants are especially suitable for mapping environmental variability in wetlands, as they respond quickly to environmental gradients and are good indicators of habitat preference. We describe the composition of herbaceous species in two oligotrophic wetland ecosystems, floodplains along black-water rivers (igapó) and wetlands upo

2. PLANT RICHNESS AND LIFE FORM DIVERSITY ALONG VEGETATION AND FOREST USE GRADIENTS IN NORTHWESTERN PATAGONIA OF ARGENTINA
ABSTRACT The imbalace between the increase in the demand and the decrease in the supply of products from natural forests, partly explains the on-going development of exotic tree plantations. In northwestern Patagonia of Argentina, Pinus ponderosa (Pinaceae) afforestation plays a key role in ameliorate degraded soils, but may also reduce biodiversity. The eco

3. Trepadeiras de um remanescente de floresta estacional semidecidual no sudeste do Brasil
Resumo Plantas trepadeiras têm papel ativo na dinâmica das comunidades florestais e são importantes como fonte de alimento à fauna. Neste estudo caracterizamos esta sinúsia em um remanescente de Floresta Estacional Semidecidual (FES) e produzimos uma chave de identificação e pranchas fotográficas para auxiliar na identificação destas plantas. Adici

4. Influence of volume container in the production of rhizomes in Seemannia (Gesneriaceae)
Resumo Seemannia Regel pertence à família Gesnereacieae. É uma planta perene herbácea com flores coloridas e brilhantes que produz rizomas escamosas carnudas com gemas dormentes axilares. O objetivo deste estudo foi avaliar o efeito do volume do recipiente na produção e na qualidade dos rizomas. Foram utilizadas plantas de um híbrido selecionado de Se

5. Fitossociologia dos componentes lenhoso e herbáceo em uma área de caatinga no Cariri Paraibano, PB, Brasil
RESUMO Caatinga sensu stricto é a vegetação típica do semiárido brasileiro, adaptada à forte sazonalidade das chuvas e às altas temperaturas. Possui alta riqueza de espécies e alto nível de diversidade beta. O objetivo do estudo foi documentar a flora e fitossociologia das plantas lenhosas e herbáceas de uma área de caatinga. Para isso, amostramos

6. A leaf bud technique for rapid propagation of cassava (Manihot esculenta Crantz)
ABSTRACT The slow rate of multiplication is one of the main constraints on the production of cassava (Manihot esculenta Crantz). This work aimed to evaluate the use of leaf buds for rapid propagation of cassava varieties. Leaf buds were excised from three cassava varieties (BRS Kiriris, 98150-06 and 9624-09) for plantlet generation. The experiment was comple

8. Updates on extratropical region climbing plant flora: news regarding a still-neglected diversity
ABSTRACT Most studies concerning climbing plants have focused on lianas, forest ecosystems, and tropical regions. Thus, the majority of existing information is not relevant to all climbing plants (lianas and vines) or all ecoregions of the world (forested and non-forested). We provide an update on floristic and distributional data available for climbing plan

11. Plant species diversity in a Neotropical wetland: patterns of similarity, effects of distance, and altitude
ABSTRACT The Brazilian Pantanal is an extensive wetland with heterogeneous habitats, primarily due to the river-floodplain system and plants with differential adaptations and reproductive strategies. Factors such as altitude, distance among plant formations, and flood pulse must be considered to better understand its diversity. Aiming to assess the influence

12. Antileishmanial activity of the essential oil from Tetradenia riparia obtained in different seasons
The herbaceous shrub Tetradenia riparia has been traditionally used to treat inflammatory and infectious diseases. Recently, a study showed that T. riparia essential oil (TrEO) obtained in summer has antileishmanial effects, although these results could be influenced by seasonal variation. This study evaluated the activity of the TrEO obtained in different s
