Última Structure des peuplements bactériens : approche méthodologique et premiers résultats en milieux lagunaires 5 Troussellier, M; Baleux, B.. After the enumeration of hétérotrophie bacteria from mediterranean and atlantic lagoons water and sediment by means of cultural methods, the qualitative study of each bacteria is carried on with the help of the API 20 B standardized microbiological method. The distinctive characteristics of bacteria of each communities are coded so that to build matrix of binary data. The grouping of bacteria is realized by means of both linnean systematic and numerical taxonomy. The communities structure they constitute found expres­sion in a systematic dominance index (D2), a Shannon taxonomic regularity index (J) and a "functionnal" regularity index (E). To have a better description and interpretation of the main ecological features of bacterial communities, it seems...

Using water samples from several observation levels of a brackish lagoon, statistical solutions are offered for the sampling optimisation of bacteria viable counts. The variability between plate count is studied by the mean of the Taylor's power law. The sampling strategy optimisation, including several sources of variability, is realized by hierarchical analysis of variance and the estimation of the sampling cost of each source. This optimisation procedure results in a great increase of the relative efficiency of the sampling design and allow to obtain significant differences between the bacterial concentrations. The effect of the reduction of the total sampling effort on the precision of these average concentrations pointed out the scientific and...
