A study was conducted to compare the competitive
ability with weeds of the short-strawed Gaines variety
wheat and taller growing varieties under different fertility
levels at three experimental locations. The
experiments were designed so that the effects of
variety, nitrogen fertilization, and weed competition
could be evaluated. The interactions between...
This field investigation was designed to further
the understanding of the significant influence which
parent population density, as well as dispersion, have
on the dynamics of enclosed populations of the montane
vole, Microtus montanus (Peale). The study was conducted
in Klamath County, Oregon from June, 1963 to February,

This study was conducted to determine the effects of insect
infestation on areas of heating in stored grain, and to demonstrate
the ability of four species of insects to initiate or promote the
spread of these heating areas. The four insects used were the
granary weevil Sitophilus granarius (L.), the...
