Based on the distribution of major styles of projectile points, at least
two distinct periods of occupation are definable. The Early period is
tentatively dated between 1000 B.C. and...
Effects of temperature and growth stage on
vegetative bud development and stem hardiness of red-osier
dogwood during winter dormancy were investigated.
Results were related to a degree growth stage model and
were used to develop models to predict growth stages, to
quantify development, and to predict hardiness.
Maximum rest development...
