A sequence of fungal populations was observed to be associated with the progressive decomposition of red mangrove (Rhizophora mangle) leaves. A laboratory model was designed to study the role of fungi in the a c c o m p a n y i n g b i o c h e m i c a l changes--immobilization of nitrogen and decrease in organic carbon.

The bacterial community composition of an active oil field in the northweltern Gulf of Mexico. Mar. Pollut. Bull., 11(6): 153156. There were no major differences in taxonomic makeup of bacterial populations in the water column around two oil production platforms as compared to a control site,but bacterial numbers and biomass (determined by plate counts) were somewhat lower at the oil field stations. 'Oil degrading and sulphur oxidizing bacteria were more numerous within the oil field, and their numbers decreased with distance from the platforms. Crude oil did not adversely affectbacterial growth or attachment ability.' Marine Science Program, Department of Biology, University of Houston, Houston, Tex. 77(}04,U.S.A. (mjj) 80:6095 Kirk, P. W. Jr., 1979/80. The mycostatic effect of s e a w a t e r on spores of terrestrial and marine higher fungi. Botanica mar., 23(4): 233-238. Raw seawater inhibited spore germination in two out of five species of marine fungi to various degrees. Mycostasis was reduced or eliminated by treatments such as addition of glucose or ammonium phosphate, heating, evaporation and reconstitution, charcoal filtration, etc. The mycostatic principle apparently involves the combination of low endogenous and exogenous reserves and the presence of volatile inhibitors.

Mycoflora of turtlegraas (Thalassia testudinum Konig) as recorded after s e a w a t e r incubation. Botanica mar., 23(4): 265-275. Six hundred twenty-nine samples of turtlegrass from a variety of sites were incubated without added carbon sources to investigate changes in fungal community structure, biommm and organic matter as the leaves aged and decomposed. NowakowskieUa sp. (or Cladochytrium?), a polycentric rhizomycelial chytrid, was dominant on the submerged grass; and, while marine filamentous Oomycetes and aquatic Hyphomycetes were target groups, they were observed infrequently and are probably relatively unimportant agents of turtlegrass decomposition, except perhaps in the intertidal zone.
