Point-centered quarter and line-intercept methods of vegetation analysis
were used to compile species lists and determine species density, frequency,
mean basal area and dominance. A relation exists between the...

To obtain data on the decomposition of the forest floor, a battery operated electrolytic respirometer was developed making it possible to measure CO₂ evolution from field moist forest floor samples in situ independent of root respiration. Banks of four respirometers powered by two 12-volt batteries were installed in three old...
A quantal response model, more general than the usual logistic
model, is introduced. This model takes into account sources of
variability, or experimental error, other than that arising from variability
in response between individual organisms (or other objects on
test). It is assumed that this extra source of variation is...
