plinary research in these and other basic and novel areas of microbiology is foreseen. WHOI, Woods Hole, Mass. 02543, USA. (mjj) 84:6226 Kelly, D.P. and N.G. Carr (eds.), 1984. The microbe 1984. II. Prokaryotes and eukaryotes. Thirtysixth Symposium, Society for General Microbiology, Univ. of Warwick, April 1984. Syrup. Soc. gen. Microbiol., 36(1/2):ca. 340pp; 12 papers. A variety of topics are covered in this volume, including microbial behavior, metabolism, genetics (transposable elements, gene expression, genetic engineering), impacts on medicine and global processes, and their importance for the future of man. Other topics are 'microbes in the oceanic environment' and 'new microbes from old habitats.' (mjj) 84:6227 Kuczek, Thomas, 1984. Introductory review. Stochastic modelling for the bacterial life cycle. Mathl Biosci., 69(2): 159-169. Stochastic models for the bacterial cell cycle are reviewed as are 'their biological motivations.' A simplified description is provided for the division of a bacterium. The questions raised by some recent models are considered: e.g., the 'weak dependence of generation times in family trees,' and whether growth models (e.g. Zaritsky et al.) could predict observed cell size distributions.

The history of the study of microbes and their culture, metabolism, behavior a n d ecology is reviewed in order to elucidate the 'guiding principles and methods' inherited by microbiologists. Critical application of these principles is necessary in the study of microbial behavior. Fakultat fur Biol., Univ. Konstanz, D-7750 Konstanz, FRG. (mjj) 84:6229 Schlegel, H.G., 1984. Global impacts of prokaryotes and eukaryotes. Symp. Soc. gen. Microbiol., 36(1/2): 1-22. The hypothesis that life originated in the form of fermentative bacteria which relied on abiotically formed organic matter is summarized, followed by a discussion of the time scale and directions of polyphyletic evolution of metabolic types. Effects of

Microbial productivity and community growth rate estimates in the tropical North Pacific Ocean. Biol. Oceanogr., 3(2): 123-146. Total microbial production equivalent to 400 mg C m 2day-~ and a growth rate of 0.4 to 0.5 doublings/day were estimated from rates of nucleic acid synthesis in 0-150 m depths. Total microbial production in 150-900 m depths was 790 mg C m 2day 1; growth rates were 1.1-2.4 doublings/day. ATP measurements indicated that 10-30% of the POC in the photic zone is composed of living carbon, living biomass is in approximate steady-state, and there are no diurnal biomass fluctuations. Systematic fluctuations in ATP concentrations do occur during in-situ incubations. Dept. of Oceanogr., Univ. of Hawaii, Honolulu, Hawaii, USA.

Optic glass fibers were used to illuminate different parts of branches of Stylophora pistillata colonies; illumination enhanced the incorporation of ~4Clabelled products in tissue, organic matrix and skeletal carbonate compartments. No evidence was found for 'upward translocation' of photosynthate from branch bases to tips. Possible mechanisms of dark CO 2 fixation are discussed. Mar. Biol. Res.
