Developers could serve users better by agreei ng to make their software work together in an integrated fashion.

Don) clones were studied in a dry environment on the Canterbury plains of the South Island, New Zealand. Four pasture competition gradients were used: (1) total weeding, (2) 2m diameter spots, (3) 1m diameter spots, and (4) a

Don at stand and individual tree levels in Canterbury, New Zealand. Sixteen functional forms were evaluated for stands that varied considerably in stand age, site index, altitude and the number of trees sampled. The Petterson equation with exponent -5 and the two- parameter Richards' equation both gave the

Don] was investigated at a field trial in Canterbury, New Zealand. Corewood dynamic stiffness was determined on standing trees using the stress wave method over the lower stem (0.2–2.0m) of 182 trees, from an experiment which included three contrasting genetic populations (GF1,

This study investigates whether one general allometric equation can ...

This paper reviews relevant models and decision support systems for assisting in achieving these objectives. ...
