The effects on onion thrips (Thrips tabaci) of controlled atmospheres (CAs) containing 15, 30, 45 and 60% carbon dioxide in air were determined by measuring the metabolic heat rates (MHRs) using microcalorimetry and compared with previous conventiona

An iron-rich deposit occurs on the bed of the Waiuku Stream and one of its tributaries, on Mt Ruapehu, New Zealand. The upper limit of the deposit is a spring which vents in the bed of the tributary. Isotope ratios, 18O/16O, D/H, and 13C/12C, indicat
