Bdellovibrio bacteriovorus is a small parasitic bacterium present
in soil, mud, and aquatic habitats. Due to its lysis of Gramnegative
bacteria, an important role in soil ecology has been suggested
for this organism. A study of effects of herbicides upon
Bdellovibrio might consequently be of considerable value.
In this study...
This study investigated several physiological aspects of the
water economy of the Sage Sparrow, Amphispiza belli nevadensis,as
they relate to the ability of this species to inhabit xeric desert environments.
When maintained in captivity on a dry diet without
drinking water, Sage Sparrows gradually lost weight and died. During the...
Some effects of hormone treatment on feedlot heifers were
studied. The treatments were 15 mg diethylstilbestrol (DES) implant,
Synovex H implant, .25 mg oral melengestrol acetate (MGA)
per head per day, and .40 mg oral MGA per head per day. One
hundred heifers, 20 to each treatment, were used. All...
Acetaldehyde is known to be responsible for the green
or yogurt-like flavor defect of lactic cultures. This study was undertaken
to extend the knowledge of acetaldehyde production and utilization
by microorganisms normally found in mixed-strain butter cultures.
It is anticipated that the resulting information will contribute
to a more thorough...
This bibliography is a continuation of a series formerly prepared by Division 6, Glues and Gluing, of the Forest Products Research Society, and published in the Forest Products Journal. The last such list was published for the year 1963.
Cambial activity in white spruce stems in Alaska was observed
from April, 1964 to September, 1965 in over 300 samples taken from
50- to 60-year-old natural stands. Mitotic index was used as a measure
of the rate of periclinal division of fusiform cells in the cambial
zone. Anticlinal divisions are...
The study was conducted over approximately 191,000 acres in central Klamath County, Oregon. The research had three objectives: first, to describe and classify the seral and near-climax vegetation by using polyclimax principles; secondly, to determine the southern extension of five plant associations and one plant associes as previously described by...
