Cuantificación de la respiración y biomasa microbiana en Andisoles del sur de Colombia

Agro Sur, 2019
Soil respiration was evaluated by quantifying CO2 and carbon from microbial biomass (CBM) in a livestock production system that integrates different land uses, located south-east of the municipality of Pasto. The evaluated uses correspond to secondary forest, prairie and silvopastoral system (Ssp), at two depths (0-10 cm and 10-20 cm).

Deforestation-free land-use change and organic matter-centered management improve the C footprint of oil palm expansion. [PDF]

Glob Chang Biol, 2022
Alternative land‐use changes like degraded savannas conversion holds potential to replace tropical deforestation and its pernicious effect on ecosystem aspects. However, lack of empirical evidence hinders the understanding of the impacts of such alternative pathway for sustainable agricultural development on important ecosystem processes. Here, we show

AISLAMIENTO Y ANÁLISIS CUALITATIVO DE BIOMASA MICROBIANA FÚNGICA DEGRADADORA DE HIDROCARBUROS DE UN CENOTE DE QUINTANA ROO

Revista Internacional de Contaminación Ambiental, 2017
Se cultivo en biorreactores de puente aereo un consorcio microbiano para estudios ex situ. El consorcio fue obtenido de un cenote contaminado con fenantreno y naftaleno ubicado en la ciudad de Cancun, Quintana Roo, Mexico. En este trabajo se mostro que el consorcio microbiano esta tambien compuesto por hongos con al menos una especie de Cladosporium ...

Ectomycorrhizal fungi and the nitrogen economy of Nothofagus in southern Patagonia. [PDF]

Ecol Evol
Ectomycorrhizal fungi play essential roles in nitrogen cycling and plant nutrient uptake at high latitudes. However, they have disproportionately been studied in boreal forests dominated by evergreen conifers. We characterized ectomycorrhizal associations and the nitrogen economy of co‐occurring deciduous and evergreen angiosperms from the genus ...

Efectos de dosis de ceniza de cáscara de arroz sobre la biomasa microbiana y fauna edáfica en pastizal natural

Revista Mexicana de Ciencias Agrícolas
La cascarilla de arroz es el residuo del procesamiento de arroz en las industrias y generalmente se reutiliza en reactores termoeléctricos para la generación de energía gracias a su poder calorífico. Mediante este proceso se obtiene la ceniza de cascarilla de arroz (CCA), que puede ser aplicada sola o en combinación con otras materias primas en la ...

No home‐field advantage in litter decomposition from the desert to temperate forest

Functional Ecology, Volume 37, Issue 5, Page 1315-1327, May 2023., 2023
Read the free Plain Language Summary for this article on the Journal blog. Abstract Litter decomposition rates are determined by the interplay of climate, decomposer organisms and litter quality. It has been suggested that the decomposer community may be locally adapted to litter quality, providing a home‐field advantage (HFA) resulting in accelerated ...

A meta‐analysis of tropical land‐use change effects on the soil microbiome: Emerging patterns and knowledge gaps

Biotropica, Volume 53, Issue 3, Page 738-752, May 2021., 2021
We identified 83 published paired studies that reported data on microbial biomass, abundance, composition, and enzyme activity under representative land‐use changes in the tropics. We found that microbial biomass, abundance, and functions were affected by land‐use change.

Conversion of Andean montane forests into plantations: Effects on soil characteristics, microorganisms, and microarthropods

Biotropica, Volume 52, Issue 6, Page 1142-1154, November 2020., 2020
Abstract Tropical montane forests in the Andes are subjected to deforestation and subsequent transformation into pastures. Abandoned pastures are frequently reforested by planting monoculture timber plantations, resulting in reduced aboveground diversity and changes in soil characteristics compared to primary forests.

Almacenamiento de muestras de suelo: incidencia sobre la cuantificación de biomasa microbiana

AgriScientia, 2005
La forma en que se conserva la muestra influye sobre la determinación de biomasa microbiana. Se evaluó el efecto de distintas formas de almacenamiento sobre el C y N de la biomasa microbiana (C-BM, N-BM) y sobre el cociente metabólico (qCO₂). Los tratamientos fueron: refrigeración a 4 °C, congelamiento a -12 °C (con posterior preincubación y sin ésta ...
