Seven in vitro trials were conducted to compare the effects of
soaking annual ryegrass straw in solutions of sodium hydroxide (Na₄OH),
potassium hydroxide (KOH), ammonium hydroxide (NH₄OH), or sodium
formate (NaCHO₂) at varying levels. Dry matter digestibility (DDM)
was the criterion used to measure treatment response. A 3 x 3...

Adults of six previously described species common to the
United States have been studied in detail. The mandibles, stridulatory
peg, and male genitalia...
Two experiments were conducted using coturnix quail to determine
the effects of dieldrin and calcium on the reproductive performance
of this species. In both experiments quail were raised on a
soybean-meal glucose-monohydrate ration. At 25% egg production
the quail received diets containing 0, 10 or 25 ppm of dieldrin in...
The genus Lichnanthe Burmeister contains eight extant and one
fossil species which are strictly nearctic in distribution. The
subfamily Glaphyrinae, however, is distributed nearly world-wide.
Five species were previously described and three are described as
new herein. All eight extant species are described in detail herein,
synonomies are made current,...
Grazing on the mountainous forested ranges of the Camp Creek
Unit, Malhuer National Forest, was typified by irregular distribution
of free-ranging cattle. A combination of management and physical,
topographic constraints caused cattle to concentrate on the riparian
zone early in the grazing season in 1977 and 1978. A large percentage...
The primary purpose of this study was to determine the work values of the emotionally disturbed adolescents and to compare these values with those indicated by adolescents
