Synoptic determination of living/dead and active/dormant bacterial fractions in marine sediments.

abstract：:Turf, consisting of closely spaced grasses and the subtending soil, is a unique ecosystem subject to intense management. Yet soil organic matter accumulates quickly and reaches equilibrium after 20 to 50 years. Resource availability is an important driver of species richness and theoretically their relationship is exp...
