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 ...
Edaphic and pyric influences on two contiguous savannas of East Texas
Vegetation, soil, history (land use and tree age), site favorability (tree growth rates), and flammability were examined in four contiguous East Texas communities, two of which are savannas. The data suggest that woody ...
Effect of Haploid Syndrome abnormalities on germ cell number in Rana Pipiens
This investigation attempts to ascertain whether or not abnormal morphology in embryos of Rana pipiens, such as that seen in haploid animals, has an effect on the number of germ cells present on the gonadal ridge. The ...
Germ plasm and germ cell migration in embryos developed from aged eggs of Rana Pipiens
A substantial amount of research supports the purported role of germ plasm as a cytdsplasmic determinant for germ cells, but the precise function of germ plasm is still unknown. In order to gain further information on the ...
Effects of age on toxicity to freshwater algae of water soluble extracts of No. 2 fuel oil
The effects of fresh-prepared, 4-day-aged and 8-dayaged Ho. 2 fuel oil water soluble fractions on the growth of Selenastrum capricornutum were investigated. The freshprepared water soluble fraction inhibits both the growth ...
