    Notes: Abstract The Western Australian termite,Drepanotermes tamminensis (Hill), harvests various plant materials according to biomass availability. The main litter components harvested by this termite in a woodland dominated byEucalyptus capillosa are bark and leaves of the major tree species, while in shrubland dominated byAllocasuarina campestris, shoots of this species are taken. Harvesting mainly occurs during the autumn (April–May) and spring (September–October) seasons. The commencement and duration of harvesting appears to depend partly on weather conditions, with harvesting taking place at temperatures between 15 and 25°C after periods of rain. This species of termite harvests approximately 15.6 g m−2 year−1 and 3.2 g m2 year−1 (dry weight of plant material) in the woodland and shrubland, respectively.

    Notes: Abstract A survey of the distribution and density of mounds of the harvester termite,Drepanotermes tamminensis (Hill), was carried out in the Durokoppin Nature Reserve, Western Australia in 1990. Vegetation and, to a lesser extent, soil type, appear to be important factors in determining density and distribution of termite mounds within the Reserve. A more detailed study of mounds in Wandoo (Eucalyptus capillosa) woodland and Casuarina (Allocasuarina campestris) shrubland indicated that the total number and size of mounds were significantly higher in the woodland than in the shrubland. The total wet weight biomass ofD. tamminensis was calculated as 3.74 gm−2 (37.4 kg ha−1) in the woodland and 1.69 gm−2 (16.9 kg ha−1) in the shrubland. Thus, of the two favored habitats, Wandoo woodland appears to be more optimal for this termite species than the Casuarina shrubland.

    Notes: Summary An NADH oxidase purified from the extreme thermophileThermus thermophilus HB8 is a monomeric flavoprotein with a 1 ∶ 1 ratio of flavin-adenine dinucleotide (FAD) to the polypeptide chain. It catalyzes in vitro the oxidation of reduced NADH or NADPH with the formation of H2O2. The gene encoding the NADH oxidase fromT. thermophilus HB8 was cloned, and its nucleotide sequence was determined. The molecular mass of 22,749 Da, as deduced from thenox gene, agrees with that of the purified NADH oxidase fromT. thermophilus HB8, as estimated by mass spectrometry. Thenox gene does not contain a GX4GK consensus sequence typical for nucleotide binding proteins. Thenox gene was overexpressed inEscherichia coli, and a protocol for the rapid purification of theE. coli-borneT. thermophilus NADH oxidase or its His6-tagged analogue was developed by using thermal denaturation step and affinity chromatography.

    Notes: Abstract A series of papers have been published which describe the influence of vegetation and soil type on the Western Australian wheatbelt termite,Drepanotermes tamminensis (Hill), and also on its litter harvesting levels and contribution to the soil nutrient budget. This paper integrates these findings by means of a computer simulation model. The model consists of three modules which respectively describe the dynamics of litter on the ground, the dynamics of litter within termite mounds and how these in turn influence nutrient loads within the habitat. The outputs of the model suggest that this litter harvesting termite plays an important role in the nutrient dynamics of the area and it provides an estimate of the unmeasured variable, litter consumed in mounds by termites, which is consistent with measurements for other termite species with similar feeding habits.

    Notes: Summary Decomposing debris of Chinese cabbage was found to be harmful to a following mungbean crop grown in the greenhouse. Aqueous or methanolic extracts of decomposing Chinese cabbage residues in soil inhibited the seed germination of mungbean, and the growth of mungbean seedlings. The same effect was observed when mungbean was grown in soil in which Chinese cabbage had previously been grown. No toxicity was found in aqueous extracts of fresh Chinese cabbage shoot or root tissues.
