The structure of microplankton communities of the South Texas Outer Continental Shelf
Microplankton from 12 stations in the waters overlying the south Texas outer continental shelf (STOCS) had previously teen collected in 3 liter Niskin bottles for approximately winter, spring, and summer seasons from ...
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 ...
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 ...
Ecology and distribution of microplankton of the south Texas outer continental shelf
A seasonal study of the ecology and distribution of microplankton was undertaken for the south Texas outer continental shelf. Twelve stations were occupied for winter, spring, and summer seasons during 1975 and 1976. A ...
Functional connections between motion detectors in the optic nerve and connective of the crayfish
Results are reported here from experiments in which single unit neural activity was recorded simultaneously from the optic nerve and connective of the crayfish Procombarus clarkli to study functional connections between ...
