N2 - Temperature can fluctuate widely between different seasons, and this
may greatly impact many biological processes. However, little is known
about its influence on the functioning of benthic microbial communities.
Here we investigated the nutrient accumulation capability of periphytic
biofilm under temperature fluctuations (17–35°C). Periphytic biofilm
maintained the same nutrient accumulation capacity after experiencing
the ‘warming-hot-cooling’ temperature fluctuation under both lab and
outdoor conditions as those without temperature disturbance. In response
to temperature increase, both community composition and species
richness changed greatly and the increase in biodiversity was identified
as being the underlying mechanism boosting the sustainable function in
nutrient accumulation, indicating zero net effects of community changes.
These findings provide insights into the underlying mechanisms of how
benthic microbial communities adapt to temperature fluctuations to
maintain nutrient accumulation capacity and elucidate that periphytic
biofilm plays important roles in influencing nutrient cycling in aquatic
ecosystems under temperature changes such as seasonal fluctuations.
