Bacterial Community Assembly in a Typical Estuarine Marsh with Multiple Environmental Gradients
Bacterial communities play essential roles in estuarine marsh ecosystems, but the interplay of ecological processes underlying their community assembly is poorly understood.

| description | Bacterial communities play essential roles in estuarine marsh ecosystems, but the interplay of ecological processes underlying their community assembly is poorly understood. Here, we studied the sediment bacterial communities along a linear gradient extending from the water-land junction toward a high marsh, using 16S rRNA gene amplicon sequencing. Bacterial community compositions differed significantly between sediment transects.

Salt marshes represent highly dynamic ecosystems where the atmosphere, continents, and the ocean interact. The bacterial distribution in this ecosystem is of great ecological concern, as it provides essential functions acting on ecosystem services. However, ecological processes mediating bacterial assembly are poorly understood for salt marshes, especially the ones located in estuaries. In this study, the distribution and assembly of bacterial communities in an estuarine marsh located in south Hangzhou Bay were investigated. The results revealed an intricate interplay between stochastic and deterministic processes mediating the assembly of bacterial communities in the studied gradient system. Collectively, our findings illustrate the main drivers of community assembly, taking into consideration changes in sediment abiotic variables and potential biotic interactions. Thus, we offer new insights into estuarine bacterial communities and illustrate the interplay of ecological processes shaping the assembly of bacterial communities in estuarine marsh ecosystems.</description><identifier>ISSN: 0099-2240</identifier><identifier>EISSN: 1098-5336</identifier><identifier>DOI: 10.1128/AEM.02602-18</identifier><identifier>PMID: 30635381</identifier><language>eng</language><publisher>United States: American Society for Microbiology</publisher><subject>Assembly ; Atmospheric models ; Bacteria ; Bacteria - classification ; Bacteria - genetics ; Bacteria - isolation & purification ; Bacteria - metabolism ; Communities ; Ecology ; Ecosystem ; Ecosystem services ; Environmental gradient ; Estuaries ; Estuarine environments ; Gene sequencing ; Geologic Sediments - microbiology ; Marine ecosystems ; Microbial Ecology ; Microbiota ; Nitrogen - metabolism ; Phosphorus ; Phosphorus - metabolism ; Phylogeny ; Physicochemical properties ; rRNA 16S ; Salt marshes ; Sediments ; Soil dynamics ; Soil erosion ; Topology ; Wetlands</subject><ispartof>Applied and environmental microbiology, 2019-03, Vol.85 (6)</ispartof><rights>Copyright © 2019 American Society for Microbiology.</rights><rights>Copyright American Society for Microbiology Mar 2019</rights><rights>Copyright © 2019 American Society for Microbiology. 2019 American Society for Microbiology</rights><lds50>peer_reviewed</lds50><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c455t-4376ffb628360b49bd1e06fcb9204e1cbc84874c3fa9298cc9665003a846cf383</citedby><cites>FETCH-LOGICAL-c455t-4376ffb628360b49bd1e06fcb9204e1cbc84874c3fa9298cc9665003a846cf383</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://www.ncbi.nlm.nih.gov/pmc/articles/PMC6414364/pdf/$$EPDF$$P50$$Gpubmedcentral$$H</linktopdf><linktohtml>$$Uhttps://www.ncbi.nlm.nih.gov/pmc/articles/PMC6414364/$$EHTML$$P50$$Gpubmedcentral$$H</linktohtml><link.rule.ids>230,314,723,776,780,881,3175,27901,27902,53766,53768</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/30635381$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Yao, Zhiyuan</creatorcontrib><creatorcontrib>Du, Shicong</creatorcontrib><creatorcontrib>Liang, Chunling</creatorcontrib><creatorcontrib>Zhao, Yueji</creatorcontrib><creatorcontrib>Dini-Andreote, Francisco</creatorcontrib><creatorcontrib>Wang, Kai</creatorcontrib><creatorcontrib>Zhang, Demin</creatorcontrib><title>Bacterial Community Assembly in a Typical Estuarine Marsh with Multiple Environmental Gradients</title><title>Applied and environmental microbiology</title><addtitle>Appl Environ Microbiol</addtitle><description>Bacterial communities play essential roles in estuarine marsh ecosystems, but the interplay of ecological processes underlying their community assembly is poorly understood.
