The influence of water motion on the distribution and transport of materials in a salt marsh estuary1

Autor: Evelyn B. Sherr, R. R. Christian, Richard G. Wiegert, D. E. Whitney, Lawrence R. Pomeroy, Jörg Imberger, T. Berman, W. J. Wiebe

Publikováno v: Limnology and Oceanography. 28:201-214

Abstruct A formal approach is presented of ordering the time scales of the dominant fluxes of material in an estuary and then accordingly choosing the spatial and temporal resolution of the sampling program. In this way bounds can be derived for the

Resistance of the Microbial Community within Salt Marsh Soils to Selected Perturbations

Autor: R. R. Christian, W. J. Wiebe, Keith Bancroft

Publikováno v: Ecology. 59:1200-1210

The response of the soil microbial community in a short Spartina alterniflora salt marsh to selected, long term perturbations was examined. Alternative hypotheses of linkage between macrophyte production and the microbial community biomass and activi

Frequency distribution of coliforms in water distribution systems

Autor: W O Pipes, R R Christian

Publikováno v: Applied and Environmental Microbiology. 45:603-609

Nine small water distribution systems were sampled intensively to determine the patterns of dispersion of coliforms. The frequency distributions of confirmed coliform counts were compatible with either the negative-binomial or the lognormal distribut

Comparison of methods for measurement of bacterial growth rates in mixed batch cultures

Autor: S Y Newell, R R Christian, R B Hanson

Publikováno v: Applied and Environmental Microbiology. 43:1160-1165

Eight methods of assessing growth rate constants of bacteria were compared in batch cultures of 3-micrometers-filtered estuarine water from the Skidaway River in Ga. Mixed assemblages of bacteria were grown under four nutrient regimes of added yeast

The effects of temperature upon the reproduction and respiration of a marine obligate psychrophile

Autor: R. R. Christian, W. J. Wiebe

Publikováno v: Canadian Journal of Microbiology. 20:1341-1345

The growth and respiration rates of a marine obligate psychrophile, Vibrio sp., were determined in a complex medium using optical density and viable counts and a polarized oxygen-electrode system. Growth rate was optimal at 7C and decreased at 10C, t
