1. Comparative wood anatomy of species of Psychotria L. (Rubiaceae) in Atlantic Rainforest remnants of Rio de Janeiro State, Brazil
ABSTRACTPsychotria is the largest Rubiaceae genus and one of the most abundant in the Atlantic Rainforest of Rio de Janeiro State. The present work aims to characterize and compare the wood of nine of these species. ThePsychotria wood were characterized by: slightly distinct growth rings; diffuse porosity; solitary vessels or on radial multiples of 2-6 or cl

2. Bioindicadores de qualidade de solo em diferentes ecossistemas
Changes due to soil management and cultivated plant species may influence carbon, nitrogen and phosphorus cycling. Cycling depends on the integration of physical, chemical and mainly microbiological processes. This work assessed some microbial activity and processes related to carbon, nitrogen and phosphorus cycles in soil from six ecosystems in Guarapuava,

4. Structure and Composition of vascular epiphytes in a two vegetation formations in Ilha da Marambaia Mangaratiba, RJ / Estrutura e Composição de epífitas vasculares em duas formações vegetais na Ilha da Marambaia Mangaratiba, RJ
The vascular epiphytes belong to a guild that occupies other plants (usually arboreous species) as support for fixing without parasiting them. This way of life have some disadvantages for the nutrients and water acquisition and therefore showed itself excessively sensitive to environmental variations in the forest. Having in view this aspect among others, th

5. Estrutura e restauração de cerradão em Palmas - TO e germinação de sementes de Buchenavia tomentosa Eichler, Hymenaea stigonocarpa Mart. ex Hayne, Guazuma ulmifolia Lam. e Enterolobium gummiferum (Mart.) J.F. Macbr / Structure and restoration of ceradões in Palmas-TO and germination of seeds of Buchenavia tomentosa Eichler, Hymenaea stigonocarpa Mart. ex Hayne, Guazuma ulmifolia Lam. and Enterolobium gummiferum (Mart.) J.F. Macbr
The fast growth of Brazil in the last decades, broadly divulged by the media wordwide is threateming severely the great diversity of the ecosystems found in the Country. In the State of Tocantins, Brazil, with the broadening of the agricultural and livestock frontier, of the real estate espansion and of the mining activities, great strips of the remaining ve

7. Variabilidade de cinco espécies arbóreas da região de cerrado do Brasil Central para medidas de germinação e emergência / Variability of five arboreous species of the Central Brazil cerrado region for germination and emergency measurements
Basic studies of seed germination and seedling emergence assume an important role within scientific researches due to the devastation and fragmentation of the native vegetation of the Cerrado. Thus, in the present study the processes of seed germination and seedling emergency were evaluated using the linear correlations among the measurements calculated for

12. Estrutura e dinâmica de uma população de Caesalpinia echinata Lam. (pau-brasil) no litoral norte da Paraíba : uma perspectiva para conservação da espécie
The Pau-Brasil (Caesalpinia echinata Lam.) is a native species of Mata Atlântica, explored extensively since the discovery of Brazil. Nowadays almost disappeared, as a result of the coast forest devastation, being part of the official list of brazilian flora species threatened with extinction. This work had the objective of studying the dynamic and the stru
