Abstract


PROTISTAN AND BACTERIAL PLANKTON COMMUNITIES IN COASTAL WATERS OF QATAR (ARABIAN GULF)

The coastal waters of Qatar belong to the least studied and exploited marine environments worldwide, when it comes to microbial diversity. This is unsatisfying not only because coastal habitats are economically and ecologically extremely important (ecosystem services) but also because Qatari waters may hold as yet unknown and valuable microbial resources. Therefore, we set out for the first time in the Gulf a microbial eukaryote and prokaryote plankton diversity survey at 14 different sampling sites subjected to diverse human activities. One pristine sampling site was included as a benchmark and reference site, as well as a hypersaline sampling site from an inland sea (Khor Al-Odaid) to exploit the full spectrum of protistan and bacterial plankton diversity. From high-throughput sequencing (Illumina), we obtained and analyzed 6,725,058 amplicons of the hypervariable V4 region and 3,796,316 amplicons of the hypervariable V3/V4 region of the small subunit ribosomal RNA gene (18S/16S rRNA) and from all 14 sampling sites. The lowest eukaryotic diversity was found at the inland sea site, where salinity was twice as high as in other Arabian Gulf areas. This confirms salt as a strong environmental selection factor for plankton communities.
