Glutamine synthetase activity is present in both the cytosol and
bacteroid fractions of soybean root nodules. Total activity measurements
indicate that at least 90% of the activity in nodules is located
in the cytosol. Results reported by McParland, et al. (29), showed
that many properties of glutamine synthetase from nodule...
The use of heated seawater for enhancing the culture of Pacific salmon was investigated. Food consumption rate, gross food conversion efficiency, growth rate, and survival of chum (Oncorhynchus keta) and pink (O. gorbuscha} salmon fed to satiation were determined in relation to water temperature and body weight. Both species of...
The need for classifying vegetation in a more precise way is
evident. Also, there is a need to provide a hierarchical classification
scheme that will match changes in image characteristics as one
moves through the scales from space to conventional aerial photography.
Such refined classifications of vegetation are the first...
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,...
