Montserrat Aquatic Sciences Meeting, Aquatic Sciences: Global And Regional Perspectives - North Meets South, 22-27 February 2015, Granada, Spain We present a comprehensive study of the composition of the bacterial communities attached to particles and their temporal variations. We performed a 2-year study in a NW Mediterranean Sea coastal site (the Blanes Bay Microbial Observatory, BBMO). Monthly, 10 L of surface water were filtered sequentially through 6 size fractions: 0.2, 0.8, 3, 5, 10 and 20 µm. We 454-pyrosequenced the 16S rDNA and we processed the data with QIIME and Mothur. The results show an increase in the species richness when increasing the size fraction. More than 50% of the OTUs where specific of each fraction, suggesting that the six size fractions contain different types of particles that offer distinct microniches for the microorganisms and contribute highly in the differentiation of community composition between filters. Factors that cause important changes in bacterial community composition between size fractions and along time were episodic meteorological events, such as increases in continental runoff, and windstorms. Overall, our results indicate that a serial filtration through various filter sizes provides a more complete description of the bacterial communities attached to particles and their variability along time Peer Reviewed 2016-08-25T12:02:50Z 2016-08-25T12:02:50Z 2015-02-26 2016-08-25T12:02:50Z comunicación de congreso http://purl.org/coar/resource_type/c_5794 2015 Aquatic Sciences Meeting.
