Científicos de la Universidad de Sao Paulo, en Brasil, simularon en laboratorio ciertas condiciones extremas de temperatura y precipitaciones y analizaron sus efectos en muestras de suelo. Los resultados obtenidos señalan la posibilidad de que se produzca una modificación en el equilibrio de este gas de efecto invernadero que se genera debido a la descomposición microbiana de la materia orgánica.
Las condiciones extremas de temperatura y humedad (lluvias [...]

Climate change could significantly disrupt emissions and uptake of greenhouse gases in the Amazon rainforest, with wide-reaching global consequences. Rising temperatures and increased flooding are affecting microbial activity in floodplain and upland forest soils, leading to contrasting changes in methane dynamics, warns new research from the University of São Paulo.
The study, recently published in the journal Environmental Microbiome, points to an alarming shift in methane uptake [...]

Extreme temperatures and humidity levels (excessive rain or drought) projected for the Amazon in the context of climate change may increase the volume of methane-producing microorganisms in flooded areas and reduce potential uptake of this greenhouse gas in upland forests by 70%, with global impacts, according to a study conducted by researchers at the University of São Paulo (USP) in Brazil.
An article reporting their findings is published in the journal Environmental Microbiome . [...]

Researchers conducted an experiment to observe the effects on soil samples of extreme conditions in the laboratory. Their findings show that the balance of greenhouse gas emissions from microbial decomposition organic matter may change. Extreme temperatures and humidity levels (excessive rain or drought) projected for the Amazon in the context of climate change may increase the volume of methane-producing microorganisms in flooded areas and reduce potential uptake of this greenhouse gas in [...]

Condições extremas de temperatura e umidade (chuva excessiva ou seca) previstas para a região amazônica no contexto das mudanças climáticas podem aumentar o volume de microrganismos produtores de metano em áreas inundadas e diminuir em até 70% o potencial de consumo desse gás de efeito estufa em florestas de terra firme, causando impactos globais.
A conclusão é de um estudo realizado por pesquisadores da Universidade [...]
