Context-dependent changes in the resistance and resilience of soil microbes to an experimental disturbance for three primary plant chronosequences

摘要: The extrinsic factors that regulate soil microbial stability (resistance and resilience) are little understood, even though microbes important drivers of ecosystem function their is likely to affect carbon storage plant nutrient availability. Soils were collected across three primary chronosequences (two in New Zealand one Hawaii) differed climate, parent material time spans test the following hypotheses: i) there a tradeoff between resistance resilience key response variables, ii) this related relationship resources, iii) resources change predictably during different chronosequences, iv) if first hypotheses hold consistent for all then should chronosequences. Results showed although was resilience, role determining unclear. Within each chronosequence, positively negatively vice versa, with our second hypothesis. However, direction strength correlations depended strongly on which variable measured, chronosequence it measured in. Total amounts often trends development but way resource quality changed varied At least partly because nature these relationships, trajectory considerably Thus, found within relationships considered.
