Trees of the same diameter at breast height and total height from heavily thinned stands had more cylindrical lower boles, more upper stem taper, longer crowns with more and larger branches, more total foliage, and hence more biomass than trees from unthinned or lightly thinned stands.
This has been attributed both to activation of the enzymes of the lower glycolytic pathway (Boles et al. 1996), and to improved co-factor regeneration (Pitkänen et al. 2003).
Those in the lower 10%% of the bole were weakly correlated.
As stand age increases, mature lodgepole pine cover types may experience relatively higher autotrophic respiration rates during the growing season, compared to younger age stands characterized by smaller bole diameters and lower metabolic baselines [50].

The difference in BASE model performance for the lower two thirds of the tree bole, between the split-validation and the independent-validation data sets, can also be seen in the sawtimber RMSEs and magnitude of change in these RMSEs when the M3_HABH taper model is used instead of the BASE model (Table 4).
Furthermore, job satisfaction was associated with higher scores of 'quality of leadership', 'sense of community'workplaceacommitmentent'role-clarityity'satisfactionion with life'meaninging of work', and lower scores of 'quantitative demands', 'cognitive stress symptoms', 'role conflict', 'demanding for hiding emotions' and older practice assistants.
The second year of the experiment had average rainfall (1210 mm), and lower rainfall decreased production in control plots by 46% (GPP), 52% (TBCA), and 40% (bole growth).
With few exceptions, fire severity measures (bole char height, scorch and torch height, scorch and torch percentage) and tree mortality were much lower in forest stands treated for fuels than in neighboring untreated stands.
Tree boles with a greater amount of stem wood above 10 cm in diameter will have a lower bark proportion.
