Spatio-temporal microbial community dynamics within soil aggregates

Size fractionation and microbial community structure of soil aggregates

The microbial community structure in various microaggregates in a loamy sand soil was investigated. The microaggregates were separated into outer and inner aggregates using a series of soil washes. Further physical fractionation of inner aggregates was achieved by separation into coarse and fine sand as macroaggregate fractions, coarse and fine silt as microaggregate fractions, and clay. Resear...

Dynamics of a Soil Microbial Community under Spring Wheat

Bossio et al., 1999). Microorganisms are intimately associated with their physical and chemical environment, In arable systems, seasonal fluctuations of microbiological properand it is therefore conceivable that the temporal dynamties can be significant. We hypothesized that adaptation to soil environmental conditions may contribute to the variation observed, and ics observed will partly reflec...

Long-term tillage effects on the distribution patterns of microbial biomass and activities within soil aggregates

Microbial interactions within a cheese microbial community.

The interactions that occur during the ripening of smear cheeses are not well understood. Yeast-yeast interactions and yeast-bacterium interactions were investigated within a microbial community composed of three yeasts and six bacteria found in cheese. The growth dynamics of this community was precisely described during the ripening of a model cheese, and the Lotka-Volterra model was used to e...

Spatio - Temporal Scene Gist Dynamics

Viewers can rapidly extract a holistic semantic representation of a real-world scene within a single eye fixation, an ability called recognizing the gist of a scene, and operationally defined here as recognizing an image’s basic-level scene category. However, it is unknown how scene gist recognition unfolds over both time and space — within a fixation and across the visual field. Thus, in three...
