dc.description.abstract | Although microbial systems are well suited for studying concepts in
ecological theory, little is known about how microbial communities respond to longterm
periodic perturbations beyond diel oscillations. Taking advantage of an ongoing
microcosm experiment, we studied how methanotrophic microbial communities
adapted to disturbances in energy input over a 20-day cycle period. Sequencing of
bacterial 16S rRNA genes together with quantification of microbial abundance and
ecosystem function were used to explore the long-term dynamics (510 days) of
methanotrophic communities under continuous versus cyclic chemical energy supply.
We observed that microbial communities appeared inherently well adapted to
disturbances in energy input and that changes in community structure in both treatments
were more dependent on internal dynamics than on external forcing. The results
also showed that the rare biosphere was critical to seeding the internal community
dynamics, perhaps due to cross-feeding or other strategies. We conclude
that in our experimental system, internal feedbacks were more important than external
drivers in shaping the community dynamics over time, suggesting that ecosystems
can maintain their function despite inherently unstable community dynamics. | spa |
