We have developed extensions of traditional distance-dependent, spatial competition analyses that estimate the magnitude of the competitive effects of neighboring trees on target tree growth as a function of the species, size, and distance to neighboring trees. Our analyses also estimate interand intra-specific competition coefficients and explicitly(More)
We have developed models of sapling mortality for the eight dominant tree species of northwestern British Columbia in order to better understand forest community dynamics and succession in this important forest region. The species-specific models characterize an individual’s probability of mortality as a function of recent growth (a surrogate for(More)
The Acacia acuminata complex is a group of woody shrubs and small trees comprised of three formally described taxa (A. oldfieldii, A. acuminata ssp. acuminata and ssp. burkittii) and two informal taxa (‘small seed’ and ‘narrow phyllode’) with contrasting geographical distributions within the south-west of Western Australia. In addition, a series of variant(More)

A comparison of commercial sodium hypochlorite (NaOCl) and sodium dichloroisocyanurate (NaDCC) products was made. Solutions of NaOCl and NaDCC containing the same levels of available chlorine (av.Cl) exhibited very similar bactericidal activities, despite significant differences in pH. A level of 12.5 ppm av. Cl achieved a greater than 5 log 10 reduction of(More)
Microbiological tests were carried out to evaluate a new chlorine dioxide sterilant: Tristel OneShot. Preliminary in vitro suspension tests showed that solutions containing around 140 ppm chlorine dioxide achieved a reduction factor exceeding 10(6) of Staphylococcus aureus in 1min and of Bacillus subtilis spores in 2.5 min in the presence of 3g/L bovine(More)
A relatively new innovation in the South Af industry, this type of conveyor was first introdi Felixton mill (1984) where whole stick cane is from the spiller tables to the cane knives. A fur opment in"this field has taken place in the recent i of this type of conveyor at the new Komati mil difference is that the belts are flat, as opposed tl as installed at(More)
