- Do bacterial and fungal communities in soils of the Bolivian Altiplano change under shorter fallow periods?Gomez-Montano, L.; Jumpponen, A.; Gonzales, Miguel Angel; Cusicanqui, Jorge; Valdivia, Corinne; Motavalli, Peter P.; Herman, M.; Garrett, Karen A. (2013)Leaving fields fallow can improve soil fertility, but there is limited information on the effect of fallowing on soil microbiology. This article presents a study of soil fungal and bacterial properties in fallowed land in the Umala and Ancoriames municipalities of the Bolivian altiplano. The study tested the influence of fallowing, and of the presence of the native plant Thola, on fungal and bacterial populations. In Ancroaimes, fungal diversity increased with fallowing, while in Umala fungal diversity decreased with fallowing. Conversely, bacterial diversity with fallowing decreased in Ancoraimes and increased in Umala. The presence of Thola did not alter the level of diversity, but did result in higher populations of certain genera. Although these results demonstrate a variety of responses to fallowing, they establish its significance on bacterial and fungal populations

R.; Worcester, E.; Yang, L.; Yeh, M.; Yokley, Z. W.; Yoo, J.; Yu, B.; Yu, J.; Zhang, C. (2015-04-01)The US neutrino community gathered at the Workshop on the Intermediate Neutrino Program (WINP) at Brookhaven National Laboratory February 4-6, 2015 to explore opportunities in neutrino physics over the next five to ten years. Scientists from particle, astroparticle and nuclear physics participated in the workshop. The workshop examined promising opportunities for neutrino physics in the intermediate term, including possible new small to mid-scale experiments, US contributions to large experiments, upgrades to existing experiments, R&D plans and theory. The workshop was organized into two sets of parallel working group sessions, divided by physics topics and technology. Physics working groups covered topics on Sterile Neutrinos, Neutrino Mixing, Neutrino Interactions, Neutrino Properties and Astrophysical Neutrinos. Technology sessions were organized into Theory, Short-Baseline Accelerator Neutrinos, Reactor Neutrinos, Detector R&D and Source, Cyclotron and Meson Decay at Rest sessions.This report summarizes discussion and conclusions from the workshop.
- Pyrosequencing to determine the influence of fallow period on soil microbial communities in the Bolivian HighlandsGomez, L.; Jumpponen, A.; Herman, M.; Garrett, Karen A. (2009)Using pyrosequencing methods, we are characterizing the responses of microbial communities in these systems to fallow period and the presence of Thola. In the first phase of the project, we have analyzed soil fungal diversity, as reported here. In the next phases of the project we will analyze both fungal and bacterial community composition in more detail in the Bolivian altiplano and in Zambian agricultural systems, synthesizing microbial community data with socioeconomic and soil physico-chemical data.
- Pyrosequencing to determine the influence of fallow period on soil microbial communities in the Bolivian HighlandsGomez, L.; Jumpponen, A.; Gonzales, Miguel Angel; Cusicanqui, Jorge; Valdivia, Corinne; Motavalli, Peter P.; Herman, M.; Garrett, Karen A. (2010)This poster addresses the shortened fallow periods in the Bolivian highlands, which result from the desire to increase short-term crop yields. Researchers conducted a study using 454-pyrosequencing techniques to characterize the response of the microbial community to the length of fallow period and the presence of plants, and the effect this response has on soil quality. The results of this study imply that the increase in fallow years was related to an increase in dominance in both fungal and bacterial communities.
- Soil Metagenomics to identify indicators of soil degradation in the Bolivian HighlandsGomez, L.; Jumpponen, A.; Herman, M.; Garrett, Karen A. (2008)The Bolivian Highlands (approximately 4000 masl) are experiencing changes in agricultural practices due in part to climate change and economic pressures. Traditional fallow periods are being shortened in an effort to increase yield, but this may be at the expense of soil quality. We will study soil microbial metagenomics using pyrosequencing methods, which allow us to place hundreds of thousands of individual microbes in taxonomic categories. Our goal is to identify microbes that may serve as indicators for the process of soil degradation and to understand the response of soil microbial communities to changing land management practices.
