Evidence to support this includes the significant differences between samples using PERMANOVA (p less then 0.001), the clear separation in ordination space of samples clustered by sampling method, the significantly higher richness in the surface samples (p less then 0.001), and the considerable variation in relative abundances of various taxa and taxonomic groups. Richness and evenness were higher among the surface-collected samples, possibly due to collector bias, weathering artifacts, or spatial and temporal variability. Pa
