1. Establishment of Leguminous Trees in the Soil of a Shooting Range
ABSTRACT Shooting range activities risk contaminating the soil, posing potential risks to human health, the local biota, and water sources. Considering that soil organisms are the first to be affected by contamination, this study aimed to evaluate the initial growth of the leguminous tree Albizia polycephala and its association with microbes in soil taken fr

2. The relationship between plant density and survival to water stress in seedlings of a legume tree
ABSTRACT Competition for soil water is one of the major processes that drive the assembly of plant communities, particularly in regions subjected to long dry seasons. The relationship between plant density and soil water competition has strong, but poorly understood, practical implications for population dynamics, restoration and conservation. We planted see

3. Phenotypic, genetic and symbiotic characterization of Erythrina velutina rhizobia from Caatinga dry forest
Abstract Erythrina velutina ("mulungu") is a legume tree from Caatinga that associates with rhizobia but the diversity and symbiotic ability of "mulungu" rhizobia are poorly understood. The aim of this study was to characterize "mulungu" rhizobia from Caatinga. Bacteria were obteined from Serra Talhada and Caruaru in Caatinga under natural regeneration. The

4. Pollination biology of melittophilous legume tree species in the Atlantic Forest in Southeast Brazil
ABSTRACT This study describes the floral phenology and morphology, reproductive biology and pollinators for eight legume tree species, Schizolobium parahyba, Senna macranthera, and Senna multijuga (Caesalpinioideae), as well as Andira fraxinifolia, Lonchocarpus cultratus, Pterocarpus violaceus, Swartzia oblata, and S. simplex (Papilionoideae), in the Atlanti

5. Tree legumes: an underexploited resource in warm-climate silvopastures
ABSTRACT Tree legumes are an underexploited resource in warm-climate silvopastures. Perceived benefits of tree legumes include provisioning (browse/mast, timber, fuel, human food, natural medicines, and ornamentals), regulating (C sequestration, greenhouse gas mitigation, soil erosion control and riparian buffers, shade, windbreaks, and habitat for pollinato

6. Food quantity and quality of cassava affected by leguminous residues and inorganic nitrogen application in a soil of low natural fertility of the humid tropics
ABSTRACT The aim of this study was to test the hypothesis that the quality and quantity of biofortified cassava root in a humid tropical environment can be modified with the application of a combination of low- and high-quality residues of leguminous tree species. The experiment was designed as a 6 × 2 factorial (a combination of 4 legume species versus 2 l

7. Genetic diversity analysis among pigeonpea genotypes adapted to South American regions based on microsatellite markers
The pigeonpea [Cajanus cajan (L) Millspaugh] is one of the most important perennial legume crops utilized in the food, fodder, soil conservation, crop-livestock integrated systems, reclaiming of degraded pastures and symbiotic nitrogen fixation. Microsatellite markers were used to estimate the genetic diversity of 77 pigeonpea genotypes selected from the ger

8. Leguminosas arbóreas - influência na produção de fitomassa e nutrientes do capim Survenola.
O objetivo deste trabalho foi avaliar o efeito da copa de leguminosas na produção de matéria seca (MS) e acúmulo de nutrientes (N,P,K,Ca e Mg) no capim Survenola (híbrido interespecífico de Digitaria setivalva x D. valida). Para isso, foram feitas amostragens na parte aérea do capim em cinco áreas distanciadas do tronco da árvore de três leguminosa

9. Morfofisiologia e valor nutritivo do capim-braquiária sob sombreamento natural e a sol pleno
O objetivo deste trabalho foi avaliar características morfofisiológicas e o valor nutritivo da Brachiaria decumbens, nas épocas chuvosas de 2003 e 2004, em um sistema silvipastoril, com faixas de 30 m de largura com essa gramínea, alternadas com faixas de 10 m com árvores de Acacia mangium, A. angustissima, Mimosa artemisiana, Leucaena leucocephala x L.

10. Tropical terrestrial model ecosystems for evaluation of soil fauna and leaf litter quality effects on litter consumption, soil microbial biomass and plant growth.
Abstract ? The aim of this work was to evaluate whether terrestrial model ecosystems (TMEs) are a useful tool for the study of the effects of litter quality, soil invertebrates and mineral fertilizer on litter decomposition and plant growth under controlled conditions in the tropics. Forty-eight intact soil cores (17.5-cm diameter, 30-cm length) were taken o

11. Introdução e avaliação de leguminosas arbóreas em pastagens da baixada e região serrana do estado do Rio de Janeiro.
O objetivo do presente trabalho foi selecionar espécies de leguminosas arbóreas introduzidas em pastagens por meio de mudas pequenas (com 50 cm em média de altura), sem proteção e na presença de gado. Para isso, foram introduzidas mudas de 16 espécies (tratamentos) em pastagens de Brachiaria spp. e de Cynodon Tifton-85 em sete locais (blocos), sendo q

12. Influência de leguminosas arbóreas na mcrofauna do solo em pastagem.
Objetivou-se com o presente trabalho avaliar o efeito de quatro espécies de leguminosas arbóreas fixadoras de nitrogênio atmosférico em um pasto de capim Marandu (Brachiaria brizantha), na densidade, diversidade, eqüabilidade e riqueza da macrofauna de um Argissolo Vermelho Amarelo de baixa fertilidade natural. O grupo Oligochaeta se destacou nos consó
