abstract = {Opencast mining for lignite continuously creates areas of
land that require restoration. Here we applied a
chronosequence approach to investigate the development of
soil bacterial communities during 52 years as influenced by
the restoration process and subsequent changes in soil
physico-chemical conditions starting from the initial
reclamation of the sites. By comparison with the unaffected
soils near the mine, we were able to address the question if
soil bacterial communities have reached a steady state
within 52 years, which is comparable to the original soil.
Our study revealed three distinct phases of the restoration
process, each with a specific bacterial community
composition. The effect size of these changes was similar to
the one observed for seasonal dynamics at our sites. At the
beginning of the restoration process Flavobacteriaceae,
Cytophagaceae and Sphingobacteriaceae were found as typical
members of the bacterial community as well as Rhizobiales as
a result of the cultivation of alfalfa on the restored
plots. At later stage the families Peptostreptococcaceae,
Desulfurellaceae as well as Streptomycetaceae increased in
relative abundance and became dominant members of the
bacterial community. Even though overall bacterial abundance
and richness exhibited values comparable to the original
soil already 5 years after the start of the restoration
process, main responder analyses reveal differences in the
bacterial community structure even 52 years after the start
of the restoration process. Mostly Nitrospirae were reduced
in abundance in the soils restored for 52 years compared to
the original soils. To broaden the significance of our
study, we compared our data bioinformatically with published
results from other restored areas, which were previously
affected by opencast mining. Despite different durations of
the different restoration phase, we could observe a large
degree of conformity when bacterial patterns of succession
were compared indicating common modes of action of
ecological restoration tools for bacterial communities.},
