Growth rate, tree form and bark texture of Quercus falcata Michx. and Q. falcata variety pagodaefolia E11. in four stands in Southern East Texas
Quercus falcata Michx. growth rate, importance (basal area), tree form, and bark texture were examined over a local gradient in soil moisture (as inferred from site vegetation, slope position and soil texture) . At drier ...
Lead in Texas wetlands and its relationship to waterfowl hunting
Lead shot deposited in wetland ponds by waterfowl hunters over a number of years may be a significant source of lead in localized areas in this environment. To determine whether such shot contributes to the overall lead ...
Amino acid transport in Trypanosome gambiense
Using C-labeled amino acids, absorption of L-lysine, L-arginine, L-glutamate, L-phenylalanine, L-methionine, L-threonine, L-alanine, and L-glycine were studied. All amino acids appeared to be absorbed by both simple diffusion ...
Ribonucleic acid and morphogenesis in the fungus, Mucor rouxii
The fungus, Mucor rouxii, can grow in two morphological states depending on culture conditions. The present work analyzed total RNA populations from aerobically grown filamentous cells and anaerobically grown (in an ...
