abstract = {Arbuscular mycorrhizal (AM) fungi provide a range of
functions in natural and managed ecosystems. However, the
trajectory of AM fungal diversity after land degradation is
poorly known. We studied the succession of AM fungi along an
agricultural recultivation chronosequence after open-cast
mining near Cologne, Germany. We used high-throughput
sequencing of the large-subunit ribosomal RNA genes to
characterize the soil AM fungal communities of 10
agricultural fields spanning 52 years of recultivation.
During three years, soils are recultivated with a legume,
and then converted to agriculture to be later returned to
local farmers implementing conventional agriculture. Our
data reveal a quick and strong recovery of AM fungal
richness after a few years of recultivation, but also a
rapid decline following years of conventional agriculture.
The community structure was strongly correlated to mineral
nitrogen and phosphorus, richness peaking at high N:P ratio.
This work represents the first molecular data documenting
temporal patterns of AM fungal communities in agriculture;
it shows the deleterious effect of conventional agricultural
practices on AM fungal communities developing over time.
Nonetheless, the highly dynamic nature of AM fungal
communities suggests strategies for site-level management
for which considering N:P stoichiometry is crucial.},
