| We try to organize the recent literature about organic-rich near-shore environments, in which sediments, shallow waters and reparian vegetation inter-act. We review the publications dealing with the effect of estuaries, and mangroves in particular, upon halieutics in the adjacent waters. Several recurring themes emerge, which we shall list without priority as : importance of heterotrophy, at all organizational and spatial levels (the microbial loop being only one aspect), and reduced role of autotrophs in optically deep waters - importance of recycling processes - persuasive role of water body morphometry and bathymetry - importance of processes at the interfaces, together with the difficulty of spatially defining these very interfaces -blurring of... |

| Nonhost environmental reservoirs of pathogens play key roles in their evolutionary ecology and in particular in the evolution of pathogenicity. In light of recent reports of the plant pathogen Pseudomonas syringae in pristine waters outside agricultural regions and its dissemination via the water cycle, we have examined the genetic and phenotypic diversity, population structure, and biogeography of P. syringae from headwaters of rivers on three continents and their phylogenetic relationship to strains from crops. A collection of 236 strains from 11 sites in the United States, in France, and in New Zealand was characterized for genetic diversity based on housekeeping gene sequences and for phenotypic diversity based on measures of pathogenicity and ice... |
