The article, is first-authored by Christiane Werner, Laura Meredith, and Nemiah Ladd, leaders of the Biosphere 2 Water, Atmosphere, and Life Dynamics Campaign (B2 WALD) and weaves together the overarching observations of the tropical forest response to drought, its recovery, and forest resilience. Entitled “Ecosystem fluxes during drought and recovery in an experimental forest”, it…
Laura Meredith recognized for her early career success with a National Science Foundation (NSF) CAREER Award from the Atmospheric Chemistry (AGS) and Ecosystem Science (BIO) Programs entitled Unearthing the Role of Belowground Biology in Biosphere-Atmosphere Volatile Organic Compound (VOC) Exchange #2045332.

With support from UA Research Innovation and Impact, the labs of Laura Meredith (School of Natural Resources and the Environment) and Marc Verhougstraete (School of Public Health) will investigate the risks and mitigation of pathogen invasion in soils in water-saving retention and reuse applications. Dr. Vanessa Buzzard, Senior Research Specialist in the Meredith Lab, will…

Our team received two user facility awards to support genomic and metabolomic analysis of soil and root responses to drought and rewet in the WALD Campaign. First, PI Malak Tfaily (UA) was awarded a Facilities Integrating Collaborations for User Science (FICUS) grant from the Environmental Molecular Sciences Laboratory (EMSL) and the DOE Joint Genome Institute (JGI) labs to…

In the winter of 2017, the Meredith Research Group had the pleasure of hosting Carol Sayuri-Nishisaka, a MS student with Dr. Acacio Aparecido Navarrete at the Federal University of São Carlos in Sorocaba, Brazil. Carol shared her expertise in quantitative PCR analysis of N2O cycling genes, which we used to study hotspot dynamics of N2O…
At the Landscape Evolution Observatory in Biosphere 2, weathering is the main process controlling soil CO2 fluxes, and in the net, drives CO2 into the soils. In most soils CO2 is emitted due to the overwhelming role of respiration by microbes, macrofauna, and roots on the soil flux of CO2. Alex surveyed the literature and…
