Fungal decomposition of needles in pine plantations PFB - Pesquisa Florestal Brasileira
Auer, Celso Garcia; Ghizelini, Angela Michelato; Pimentel, Ida Chapaval.
A literature review was performed to discuss the fungal decomposition of needle pines and impacts on commercial forest production and sustainability. Aspects as organic matter and litter degradation, associated micobiota, and factors that condition this process are discussed. Needles are principal components of residues in pine forests and their decomposition by fungi is important to nutrient turnover. Nutrients released for soil by decomposition increases forest productivity which promotes more biomass production and fixation of carbon in trees.

MODIS Time Series to Detect Anthropogenic Interventions and Degradation Processes in Tropical Pasture. Repositório Alice
AGUIAR, D. A.; MELLO, M. P.; NOGUEIRA, S. F.; GONÇALVES, F. G.; ADAMI, M.; RUDORFF, B. F. T..
The unavoidable diet change in emerging countries, projected for the coming years, will significantly increase the global consumption of animal protein. It is expected that Brazilian livestock production, responsible for close to 15% of global production, be prepared to answer to the increasing demand of beef. Consequently, the evaluation of pasture quality at regional scale is important to inform public policies towards a rational land use strategy directed to improve livestock productivity in the country. Our hypothesis is that MODIS images can be used to evaluate the processes of degradation, restoration and renovation of tropical pastures. To test this hypothesis, two field campaigns were performed covering a route of approximately 40,000 km through...

Tratamento biológico de efluentes de indústrias de papel após floculação e coagulação com sais de alumínio e polieletrólitos naturais BABT
Reis,Edson M. dos; Nozaki,Jorge.
The flocculation and sedimentation of recalcitrant organic compounds of high molecular weight using natural polyelectrolytes, extracted from the cactus Cereus peruvianus and Opuntia ficus indica, have been studied. Organic compounds of high molecular weight from effluents of paper and pulp industries are difficult for biological degradation. However, using a mixture of aluminum salts and natural polyelectrolytes, the aggregation and settling properties of recalcitrant organics were increased if compared with conventional methods of wastewater treatment using only aluminum or iron sulfate. After flocculation, sedimentation, and filtration, the effluent was submitted to biological degradation by activated sludge process. The main advantages of using a...
