1. Morphoagronomic characterization of a germplasm collection of Furcraea spp. and Agave spp.
ABSTRACT This work was carried out in Antioquia, Colombia, in a collection of the Furcraea and Agave genera, important in the country for manufacturing strings, sacks, geotextiles, and handicrafts Currently, to enhance its use, applications have been developed in textiles, biodegradable materials and thermo-acoustic insulation, among others. The aim of this

2. Performance of cover crops under two irrigation regimes in the Coastal Tablelands region of Brazil
ABSTRACT There is currently a lack of information regarding the performance of cover crops grown in the Coastal Tablelands region in the North of the Brazilian state of Espírito Santo, where zero tillage is increasingly being adopted. The objective of this study was to evaluate the agronomic performance of six cover crops (ruzi grass, jack bean, and the mil

3. Reproductive phenology of aquatic macrophytes in the Cerrado-Pantanal ecotone
ABSTRACT Studies of plant phenology have been performed predominantly with terrestrial species and rarely so with aquatic communities. Such plants are fundamental for the aquatic ecosystems, representing a valuable source of resources when they are scarce in terrestrial environments for the fauna. Studies of phenology help to understand the reproduction rhyt

4. Advances in the knowledge of the natural history of aquatic plants in the Neotropics
ABSTRACT Until the mid-XX century, little awareness on the ecological services or socio-environmental problems and benefits related to aquatic plants culminated in bottlenecks on their natural history, especially for the Neotropics. In this context, Acta Botanica Brasilica (ABB) organized this special issue to promote the advancement of knowledge on this eco

5. FLORISTIC COMPOSITION AND DIVERSITY IN TERRA FIRME FOREST UNDER WATER STRESS IN THE AMAZON
ABSTRACT The studies on floristic composition are an aid in the understanding of the structure and dynamics of the plant communities, fundamental parameters for its management and conservation. Thus, the objective of this work was to evaluate the floristic composition, species richness, Shannon’s diversity and models of species abundance over a 10-year per

7. Conservation of species-rich subtropical grasslands: traditional management vs. legal conservation requirements in primary and secondary grasslands
ABSTRACT Land-use change is the main cause of biodiversity losses, and for grasslands includes changes in management. The last 10 years has seen afforestation of traditionally grazed grasslands increase considerably in the understudied Serra do Sudeste region of the Brazilian Pampa, turning the region into a mosaic of tree plantations, natural ecosystems (pa

8. Rhizobium rhizogenes-mediated transformation of Rhodiola rosea leaf explants
ABSTRACT Rhodiola rosea L. is an endangered medicinal plant distributed in mountains and in high latitude regions. For its conservation, sustainable methods for the obtaining of its bioactive compounds must be developed. This work hypothesized that leaf, stem and rhizome explants of R. rosea from different geographical origins respond differently to inoculat

9. Taxonomic study of Marsypianthes Mart. ex Benth. (Hyptidinae, Lamiaceae) in Brazil
ABSTRACT Marsypianthes is a Neotropical plant genus distributed from southern Mexico to northeastern Argentina. It is composed of six species - M. arenosa, M. burchellii, M. chamaedrys, M. foliolosa, M. hassleri, M. montana - with all occurring in Brazil except for M. arenosa, which occurs in Mexico. Marsypianthes burchellii, M. foliolosa and M. montana are

10. Root parasitism by Scybalium fungiforme Schott & Endl. is not random among host species in seasonal tropical forest
ABSTRACT Though they comprise 1 % of plant species on the planet, plant parasites are poorly known. They have been considered a threat to cultivated plants and to the conservation of host species in natural areas. Due to the complex interactions they have with their hosts, understanding their biology is fundamental to the development of conservation strategi

11. 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
