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)
Hydrogenotrophic methanogens typically require strictly anaerobic culturing conditions in glass tubes with overpressures of H2 and CO2 that are both time-consuming and costly. To increase the throughput for screening chemical compound libraries, 96-well microtiter plate methods for the growth of a marine (environmental) methanogen Methanococcus maripaludis(More)
Haptoglobin typing by vertical electrophoresis in a discontinuous polyacrylamide gel was conducted on 47 dog blood samples, of which 19 were from Doberman pinschers, 20 from German shepherds, and 8 from pit bullterriers. Two phenotypes were common in the three breeds and could not be used to differentiate between them. Canine haptoglobin phenotypes were,(More)
