  • Effects of elevated atmospheric CO2 on soil microbial

    This study reports the effects of longterm elevated atmospheric CO2 on root production and microbial activity, biomass, and diversity in a chaparral ecosystem in southern California The free air CO2 enrichment (FACE) ring was located in a stand dominated by the woody shrub Adenostoma fasciculatum   The acclimation of a nitrifying biofilter is a crucial and timeconsuming task for setting up a recirculating aquaculture system (RAS) Gaining a better understanding of the dynamics of the microbial community during the acclimation period in the system could be useful for the development of mature nitrifying biofilters In this study, highthroughput DNA sequencing was applied to monitor the Dynamics of Microbial Community During Nitrification
