Differential biodiversity responses between kingdoms (plants, fungi, bacteria and metazoa) along an Alpine succession gradient.

摘要: Biological diversities of multiple kingdoms potentially respond in similar ways to environmental changes. However, studies either compare details microbial diversity across general vegetation or land use classes relate plant community with the extent microbially governed soil processes, via physiological profiling. Here, we test hypothesis shared responses and rhizosphere bacterial, fungal metazoan biodiversities (especially across-habitat β-diversity patterns) along a disturbance gradient encompassing grazed abandoned Alpine pasture, on acid European Central Alps. Rhizosphere biological was inferred from eDNA fractions specific bacteria, fungi metazoans contrasting habitats indicative different levels. We found that patterns were weakly correlated measures similarly ordinated an evident edaphic (pH, C:N, assimilable P) but, contrary our hypothesis, did not demonstrate same patterns. While communities well separated gradient, correlating diversity, majority bacterial taxa between levels (75% bacteria ubiquitous, cf. 29% species). Metazoa exhibited intermediate response, at lowest partially overlapping. Thus, only loosely dependent exhibit strictly linked responses. This probably reflects spatial scales organisms (and their habitats) capacity invest resources persistent multicellular tissues, suggesting change are unreliable indicators below-ground biodiversity
