Biometric and gas exchange techniques were used to measure soil respiration (soil surface CO₂ efflux) and NEP (Net Ecosystem Production) across three climatically-distinct forest chronosequences in Oregon. Results indicate significant forest type, age, and forest type x age interaction effects on annual soil respiration. A regional age class distribution skewed...
The paper reviews the management and bioeconomic modeling of the Southern Bluefin Tuna
stock. It describes two studies using simultaneous, non-cooperative, three player games to predict
revenue and stock outcomes generated by a deterministic, discrete, age-structured model of the
SBT population. Two versions of the model, corresponding to biological and...
The study was conducted in order to obtain some understanding of the hydrologic characteristics of streamflow under dry weather conditions, and from this knowledge develop some means for prediction of seasonal-low streamflow quantities.
It was considered desirable to prepare "drought frequency plots" for a number of watersheds of varying sizes...
The design of checking experiments for sequential machines
which do not initially have a distinguishing sequence is investigated.
Improvem,Jnts are suggested to an existing method for
augmenting the output logic so that the machine acquires homogeneous
distinguishing sequences. To indicate how the procedure
may be implemented on a computer, elements...
The methodology of structured programming has
enabled rapid progress in many areas of theoretical
computer science. Structured programs are generally
easier to debug, test, prove and analyse. The development
of these achievements into commercially viable applications
and products has been slower than expected.
The primary reason is that most of...
Procedures are developed for integrating short-term,
area-based plans with long-term, strata-based harvest
schedules. These procedures were tested on a 4000 hectare
tract of forest land in British Columbia. It is shown that
a combination of these two approaches to forest planning
provides a spatially feasible short-term solution that is
also...
