> Coral reefs in the central Red Sea are sparsely studied and in situ data
> on physico-chemical and key biotic variables that provide an important
> comparative baseline are missing. To address this gap, we simultaneously
> monitored three reefs along a cross-shelf gradient for an entire year over
> four seasons, collecting data on currents, temperature, salinity, dissolved
> oxygen (DO), chlorophyll-a, turbidity, inorganic nutrients, sedimentation,
> bacterial communities of reef water, and bacterial and algal composition of
> epilithic biofilms. Summer temperature (29-33C) and salinity (39 PSU)
> exceeded average global maxima for coral reefs, whereas DO concentration
> was low (2-4 mg L-1). While temperature and salinity differences were most
> pronounced between seasons, DO, chlorophyll-a, turbidity, and sedimentation
> varied most between reefs. Similarly, biotic communities were highly
> dynamic between reefs and seasons. Differences in bacterial biofilms were
> driven by four abundant families:
>  Rhodobacteraceae, Flavobacteriaceae, Flammeovirgaceae, and
> Pseudanabaenaceae. In algal biofilms, green crusts, brown crusts, and
> crustose coralline algae were most abundant and accounted for most of the
> variability of the communities. Higher bacterial diversity of biofilms
> coincided with increased algal cover during spring and summer. By employing
> multivariate matching, we identified temperature, salinity, DO, and
> chlorophyll-a as the main contributing physico-chemical drivers of biotic
> community structures. These parameters are forecast to change most with the
> progression of ocean warming and increased nutrient input, which suggests
> an effect on the recruitment of Red Sea benthic communities as a result of
> climate change and anthropogenic influence. In conclusion, our study
> provides insight into coral reef functioning in the Red Sea and a
> comparative baseline to support coral reef studies in the region.
