摘要: Soil water repellency (SWR) can influence many hydrological soil properties, including infiltration, uneven moisture distribution or retention. In the current study we investigated how variable SWR persistence in field is related to microbial community under different plant species (P. halepensis, Q. rotundifolia, C. al- bidus and R. officinalis) a Mediterranean forest. The was determined through phospholip- id fatty acids (PLFA). relationships between microbiological structure properties pH, Glomalin Related Protein (GRSP) organic matter (SOM) content were also studied. Different statistical analyses used: Principal Component Analysis (PCA), ANOVA, Redundancy Pearson correlations. highest concentrations of PLFA found most repellent samples. PCA showed that microorganism composition more dependent severity than type species. Analysis, only significant factor (p<0.05) explain distributions. biomarkers directly re- lated associated with Actinobacteria (10Me16:0, 10Me17:0 10Me18:0). All results suggest strong dependence composition.
