1. Litterfall decomposition of coffee shaded with Tectona grandis or in full sun
RESUMO A serapilheira é uma importante fonte de nutrientes para o solo e a sua decomposição pode ser influenciada pelos sistemas de uso do mesmo. Este estudo teve por objetivo avaliar a decomposição de serapilheira e seu estoque de macronutrientes em dois sistemas de cultivo do cafeeiro, sendo um sombreado (CS) e outro a pleno sol (CPS). O experimento f

2. Soil phosphorus fractions and their relation to leaf litterfall in a central Amazonian terra firme rainforest
RESUMO A ciclagem de fósforo (P), mesmo sendo pouco estudada, é importante para o equilíbrio de macronutrientes em ecossistemas de floresta tropical úmida. Como P no solo ocorre em diferentes formas orgânicas e inorgânicas (frações), com diferentes graus de labilidade, supomos que essas frações variam temporalmente entre os diferentes tipos de solo

3. Different Patterns Of Nutrient Cycling In Contiguous Phytophysiognomies Of Atlantic Forest, Brazil
ABSTRACT The present study aimed to evaluate fine aboveground litterfall, deposition of nitrogen and phosphorus from total litterfall and leaf litter decomposition in areas of tall forest (Mata Alta) and low forest on sandy soils (Mussununga) in southeastern Brazil. Fine litterfall was collected monthly for two years (from June/2007 to May/2009) in 10 conica

4. The Role of Environmental Heterogeneity in the Seed Rain Pattern
ABSTRACT We focus on understanding the influence of environmental variables on ecological processes, and such a focus promotes an integrated view of forest ecological patterns. The following questions were made: Do variations in temperature, precipitation, litterfall deposition and light intensity influence the density and composition of seed rain in a stret

5. Spatial-temporal variation in litterfall in seasonally dry tropical forests in Northeastern Brazil
Resumo A produção de serapilheira é essencial para a ciclagem de nutrientes em ecossistemas terrestres. De Novembro de 2009 a Outubro de 2011, foi analisada a produção de serapilheira em duas áreas de Caatinga, um tipo de Floresta Tropical sazonalmente Seca localizada no Cariri Paraibano, na região do semiárido da Paraíba, Nordeste do Brasil. Uma da

6. Impacto da remoção de serapilheira sobre a comunidade de artrópodes edáficos em plantios abandonados de Corymbia citriodora
Resumo Experimentos de manipulação podem contribuir para a compreensão do papel ecológico da serapilheira em ecossistemas florestais. No entanto, há poucos estudos desta natureza. Os efeitos da remoção da camada de serapilheira (RS) foram avaliados sobre a comunidade de artrópodes do solo em dois plantios abandonados de Corymbia citriodora, em difere

7. Litterfall and Litter Decomposition in Pinus and Native Forests
ABSTRACT Litter production and decomposition makes it possible to supply a good part of the nutrient demand of forest stands. Although several studies on this subject have been carried out in Pinus stands in different regions of Brazil, there are no records of studies carried out in the Northeast region, or in particular in the state of Bahia. Therefore, the

8. Litterfall Deposition and Decomposition in an Atlantic Forest in Southern Goiás
ABSTRACT Brazilian biomes have been severely threatened and their conservation depends on the knowledge of intrinsic ecological processes and correct phytophysiognomy identification of legal protection purposes. Litterfall deposition and decomposition patterns associated with taxonomic composition, climate, soil and relief can be considered important tools

9. Biomass Deposition and Chemical Composition of Litterfall in Clonal Eucalyptus Plantations
ABSTRACT Productivity in clonal eucalyptus plantations depends on the genetic material and on the demand and cycling of nutrients, making studies that evaluate these requirements necessary. The aim of this study was to evaluate the effect of management (with and without thinning) on the deposition, chemical composition and nutrient contribution in litter at

10. Litterfall: A Bio-indicator for Edge Effect in a Semi-deciduous Seasonal Forest
ABSTRACT This study aimed to evaluate the use of litterfall as an indicator of fragmentation in a Semi-deciduous Seasonal Forest in Além Paraíba, MG, Brazil. Litterfall was collected monthly for one year in conical collectors (0.25 m2 of surface), located at seven distances from the forest edge: 10, 30, 60, 100, 160, 250 and 350 m. The litterfall was drie

11. Effects of habitat heterogeneity on epiedaphic Collembola (Arthropoda: Hexapoda) in a semiarid ecosystem in Northeast Brazil
ABSTRACT The spatial distribution of abiotic resources and environmental conditions can vary at small scales within terrestrial ecosystems, influencing the composition of soil fauna. Epiedaphic springtails (Collembola) of a semiarid Caatinga ecosystem were studied to determine if factors related to vegetation structure, such as species richness, aerial bioma

12. Litter Dynamics in a Forest Dune at Restinga da Marambaia, RJ, Brazil
ABSTRACT Restingas are extremely degraded, tropical sandy ecosystems and are poorly studied in terms of nutrient cycling. The present study aimed to evaluate litter dynamics in a forest dune at Restinga da Marambaia, RJ. Litterfall was collected monthly using two parallel transects installed 200 m apart from each other with 15 litter traps (0.25 m2), over t
