1. 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

2. Decomposition of Leaf Litter in Semideciduous Submontane Forest, in The Southern State of Espírito Santo
ABSTRACT The objective of this work was to understand the relationship between decomposition of leaf litter and climatic elements and determine the mineralization of nutrients in the decomposition process in a fragment of Semideciduous Submontane Forest, located in southern state of of Espírito Santo. Overall, 84 litterbags were deposited in 12 permanent pl

3. Saprobic conidial fungi associated with palm leaf litter in eastern Amazon, Brazil
Abstract: Fungi play an important role in litter decomposition in forest ecosystems and are considered an undersampled group in the Amazon biome. This study aims to describe the composition, richness and frequency of species of conidial fungi associated with palm trees in an area of the Amapá National Forest, State of Amapá, Brazil. Palm leaf litter was co

4. Post-fire consequences for leaf breakdown in a tropical stream
Resumo Objetivo Queimadas é um distúrbio natural nas paisagens do Bioma Savana. Este estudo avalia os efeitos do pós-fogo (antes e depois) na decomposição de serapilheira na comunidade de invertebrados e biomassa de fungos em diferentes detritos e malhas (fina e grossa) em riacho em curto prazo temporal.

5. Collection of Plants in situ and Conditioning of Butia lallemantii Seedlings
ABSTRACT The objective of this study is to evaluate the survival and development of Butia lallemantii seedlings collected in situ. Seedlings were collected in Alegrete/RS, classified into four stipe diameter classes (SDC) and transplanted into polyethylene bags (2 L) filled with soil-based substrate, animal waste and rice husks. Evaluations were performed a

6. Contribution of Litter and Leaf Decomposition of Byrsonima gardneriana
ABSTRACT The litter in tropical ecosystems is one of the compartments responsible for the transference of nutrients to the soil, having great importance for the conservation and maintenance of biodiversity. Thus, this study aimed to quantify the contribution and stock of litter and the leaf decomposition rate of Gardneriana byrsonima A. Juss (murici) in two

7. Nutrient cycling between soil and leaf litter in the Cerrado (Brazilian savanna) on eutrophic and dystrophic Neosols
ABSTRACT We evaluated nutrient cycling by measuring leaf litter production and decomposition in the Brazilian savanna (cerrado sensu stricto) on eutrophic (calcareous) and dystrophic (arenitic) Neosols over the same spatiotemporal scale. We installed three transects in the Cerrado with plots in each Neosol type. Areas along the transects were randomly chosen

8. Effect of Mineral Nitrogen on Transfer of 13C-Carbon from Eucalyptus Harvest Residue Components to Soil Organic Matter Fractions
ABSTRACT The amount of harvest residues retained in Eucalyptus plantations strongly influences soil organic matter (SOM), but the efficiency of conversion to SOM may vary according to the type of residue. This study evaluated the recovery of C from Eucalyptus residue components - leaves, bark, branches, roots, and a mix of all residues - in different SOM fra

9. Litter Decomposition of Two Pioneer Tree Species and Associated Soil Fauna in Areas Reclaimed after Surface Coal Mining in Southern Brazil
ABSTRACT Decomposition of leaf litter from pioneer tree species and development of associated soil meso- and macrofauna are fundamental for rehabilitation processes in reclaimed coal mining areas. The aim of our study was to evaluate decomposition of Schinus terebinthifolius and Senna multijuga to answer three basic questions: (i) What type of leaf litter de

10. Use of Organic Compost Containing Waste from Small Ruminants in Corn Production
ABSTRACT Composting is a useful way of transforming livestock waste into organic fertilizer, which is proven to increase soil nutrient levels, and thus crop yield. Remains from production and slaughter of small ruminants can become a source of important elements for plant growth, such as N, after microorganism-driven decomposition.The aim of this investigati

11. Effects of forest structure on litter production, soil chemical composition and litter-soil interactions
ABSTRACT Litter production in forest ecosystems is a major indicator of primary productivity because litter helps incorporate carbon and nutrients from plants into the soil and is directly involved in plant-soil interactions. To our knowledge, few studies have investigated the relationship between species diversity and ecosystem processes in subtropical fore

12. Clay content drives carbon stocks in soils under a plantation of Eucalyptus saligna Labill. in southern Brazil
Soil carbon accumulation is largely dependent on net primary productivity. To our knowledge, there have been no studies investigating the dynamics of carbon accumulation in weathered subtropical soils, especially in managed eucalyptus plantations. We quantified the seasonal input of leaf litter, the leaf decomposition rate and soil carbon stocks in an commer
