We examine the evidence for the possibility that 21st-century climate change may cause a large-scale "dieback" or degradation of Amazonian rainforest. We employ a new framework for evaluating the rainfall regime of tropical forests and from this deduce precipitation-based boundaries for current forest viability. We then examine climate simulations by 19(More)
BACKGROUND Recent studies suggest that gastrointestinal (GI) microbes play a part in the pathogenesis of Crohn's disease (CD). METHODS Fecal samples were collected from 16 healthy individuals and 16 CD patients (age- and sex-matched). The DNA extracted from these samples were subjected to two different methods of microbiome analysis. Specific bacterial(More)
AIMS To gain new insights into the metabolic contribution of bacterial group in the rumen. METHODS AND RESULTS Both DNA- and RNA-derived bacterial 16S ribosomal materials from bovine rumen contents were used as the template for bacterial community and analyse microbiota by three methods namely custom phylogenetic microarray, quantitative real-time PCR and(More)
