In fact, the first component (explaining 49% of variation) related well with all soil properties of reference samples (absolute correlation values of 0.55 0.96).
In the laboratory, we used replicated measurements of soil chemical properties of reference samples similar to those in the study area.
Thus, a reference system for the site-specific diversity of soil organisms consists of: reference values: lists of species expected to occur at a certain site with its specific conditions (e.g. climate, soil factors, region); a quantification of deviations from these reference values that indicate impacted habitat function.
Soils treated with sewage sludge and compost showed bacterial PLFA concentrations similar to those of reference soils, but compost treatments presented fungal PLFA concentrations that were much higher.
Analyses of a wide range of soils and reference samples (cellulose, lignin, humic substances, lignite, charcoal, coal, etc).
In summary, we would argue that there is no greater challenge to exploring the ecology and evolution of viral communities in diverse ecosystems (e.g., oceans, soils, humans) than the lack of reference genomes that cause dominance by 'viral dark matter'.
The hybridization of different technological tools provides a strategy to effectively assess microbial activity in soils within a multi-scalar frame of reference.
and English oak; 3) an unmanaged portion of the mixed plantation; 4) a yearly tilled and manured cropland; 5) an adjacent forest growing on a natural soil, which served as a term of reference.
The specific goal was the identification of "reference" states for soil sustainability and ecosystem functioning in grazed vs. ungrazed sites.
Table 1 also lists the CEC value of a soil reference sample of 12.75 ± 1.01.
