Experiments were conducted under field and greenhouse conditions
to investigate the effects of chlorpropham (isopropyl mchlorocarbanilate)
on vegetative and reproductive development in
Chewings fescue (Festuca rubra L. subsp. commutata Gaud.) and to
determine the time of induction and initiation under natural conditions.
Chewings fescue was found to be very susceptible...
The purpose of this study of the life and career of Dr. Carl
Leonard Anderson was to recount his professional contributions to
the field of health and relate these to public health and health education. The major emphasis of this study concerned Dr. Anderson's
professional life.
The accomplishment of the...
Pineal hydroxyindole-0-methyltransferase (HIOMT) activity
was monitored over a 24 h period under three different photoperiods,
16L:8D, 8L: 16D, and 12 L:12D. It was observed that in all three
groups of fish HIOMT activity was high' during the dark portion of the
photoperiod in comparison to activity during the light portion....
Two organophosphates (Ruelene and Tiguvon) and two carbamates
(Sevin and Baygon) were administered topically at various sublethal
concentrations to cricket eggs. All the pesticides caused an immediate
decrease in the acetylcholinesterase (AChE) activity level in the
embryo, but the level usually returned to normal within three days
after dosage. The...
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,...
Observations of wind, currents, sea level and hydrography
obtained during the 1972 Coastal Upwelling Experiment (CUE-I) are
described. Only phenomena with periods longer than a day are considered.
One section describes the changes observed during a period
of variable winds in early July 1972. Another describes a ribbon of
relatively...
An inexpensive method for calibrating an infrared analyzer to measure varying ranges of carbon dioxide partial pressures (Pco₂) is described. A discussion is made of the hydrographic (temperature, salinity, and sigma-t) and chemical (dissolved oxygen, AOU, Pco₂ pH, and nutrients) variables that were observed along the Newport hydrographic line in...
