Distance-based redundancy analysis (RDA) plots between enzymatic activities and bacterial (A and B) and fungal community structures (C). Different colours indicate the split in off-trail and in-trail samples (between the ruts and inside the ruts samples); shapes refer to different degrees of soil compaction (off-trail, between the ruts and inside the ruts samples). Vectors indicate enzymatic activities significantly correlated with microbial community structures (ENVFIT analysis).

... redundancy analysis (db-RDA) coupled with multiple regression analysis was used to evaluate the relationship between both microbial community structure and soil enzyme activities. The first two axes together explained 36.07 % and 48.65 % of the variance in the bacterial communities, respectively at T1 and T2 (Fig. 6A-B). Concerning the fungal communities, the total variance explained was 30.28 % and 37.44 % at T1 and T2, respectively (Fig. 6C). Db-RDA plots showed the relationships among enzyme activities and the structure of both the microbial communities, and their activities growth trends along with the changes of soil microbial communities in ...

... T1, the enzyme activities associated with the bacterial structure were arylsulfatase, protease, and alkaline phosphatase activity (Fig. 6A, File S3). Consistently with enzyme activity results (Fig. 2), the regression analysis showed that the arylsulfatase activity was positively associated with changes in bacterial structure in the undisturbed soil (off-trail samples), while the protease and alkaline phosphatase activities progressively increased along with changes in ...

... (Fig. 2), the regression analysis showed that the arylsulfatase activity was positively associated with changes in bacterial structure in the undisturbed soil (off-trail samples), while the protease and alkaline phosphatase activities progressively increased along with changes in bacterial structure in medium compacted soil (between ruts samples) (Fig. 6A). Moreover, major increases in these enzymatic activities did not appear to be connected with the structure of the bacterial community in heavily compacted soil (inside ruts samples) (Fig. ...

... T2, the enzyme activities significantly associated to bacterial community structure changed compared to T1 as acid phosphomonoesterase and β-glucosidase emerged as newly related enzymes, while protease was no longer significant ( Fig. 6B; File S3). In particular, the increment of acid phosphatase activity was connected to changes in bacterial community composition of compacted soils (inside ruts samples), while other activities (β-glucosidase, alkaline phosphatase, and arylsulfatase activity) were more associated with undisturbed soils (offtrail samples) (Fig. 6B), although ...

Similarly to bacteria, the arylsulfatase activity increased along with changes in fungal community composition in undisturbed soils (off-trail samples), while the protease activity increased along with changes in fungal community composition in medium disturbed soils (between ruts samples) ( Fig. 6C; File S3). Also, the structure of the fungal community in compacted soils (inside ruts samples) was not associated with these two activities. At T2, no enzymatic activity was significantly related to changes in fungal community structure in both compacted and notcompacted soils (File ...
