Young rats fed on a diet which contains Crotalaria spectabilis seeds or the pyrrolizidine alkaloid monocrotaline die from congestive heart failure within 36 to 60 days. At necropsy they are found to have ascites, pleural effusions, and cardiac enlargement due to right ventricular hypertrophy (Turner and Lalich, 1965; Kay and Heath, 1966). Microscopic examination reveals an increase in the media...

Daytime xylem sap flow was measured by the compensation heat pulse velocity technique in dipterocarp forest trees growing on sandy loam (haplic acrisol) and in heath forest trees growing on bleached sand (albic arenosol) in Brunei during wet and dry periods. In dipterocarp forest trees, daily sap flow was stable during the dry period but declined on rainy days presumably as a result of reduced ...

The Stanford Linear Accelerator Center (SLAC) and Deutsches Elektro-nen Synchrotron (DESY) libraries have been comprehensively cataloguing the High Energy Particle Physics (HEP) literature online since 1974. The core database, SPIRES-HEP, now indexes over 400,000 research articles, with almost 50% linked to fulltext electronic versions (this site now has over 15 000 hits per day). This database...

Changes in temperature and moisture resulting from climate change are likely to strongly modify the ecosystem carbon sequestration capacity in high-latitude areas, both through vegetation shifts and via direct warming effects on photosynthesis and decomposition. This paper offers a synthesis of research addressing the potential impacts of climate warming on soil processes and carbon fluxes at t...
