Detecting the response of Douglas-fir to nitrogen fertilization by regression of periodic annual basal area increment against basal area

Canadian Journal of Forest Research, 1988
Douglas-fir (Pseudotsugamenziesii (Mirb.) Franco) basal area response to urea fertilization at 112 and 224 kg N/ha was studied on a medium site. Regression of tree periodic annual basal area increment against basal area was used to estimate within-plot growth rates. Higher growth rates were observed in the fertilized plots.

Catecholamine innervation of the basal forebrain. I. The septal area

Journal of Comparative Neurology, 1978
AbstractThe septal area of the rat is known to receive a rich innervation by axons of catecholamine (CA) neurons. In the present study this innervatic was studied using biochemical assay of CA content and fluorescence histochemical analysis of the distribution of CA‐producing axons to determine the nuclei origin of the septal CA innervation and the ...

Basal Cell Carcinoma of the Eye Area

2016
Although surgical procedures with margin control are preferred by most surgeons for the treatment of eyelid epithelial cancers, among dermatologists Mohs being the method of choice, cryosurgery remains a valid important option.

Selection of Basal Area Factor in Point Sampling

Journal of Forestry, 1980
Abstract The basal area factor is preferably chosen by dividing the estimated stand basal area by the desired average tree count per sampling point. Bias may be introduced, generally in the form of overestimates, if the factor is varied from point to point in order to keep the count constant.

Ponderosa Pine Basal Area and the Kaibab Squirrel

Journal of Forestry, 1975
Abstract Mark-recapture methods were used to determine an index to the minimum number of Kaibab squirrels for nine trapsites. Squirrel numbers were correlated with forest characteristics, including number, basal area, and volume per acre of five tree species, and numbers of squirrel nests per trapsite.
