Project Description<\/h3>\n
\"Sharp\"
RWU’s Dr. Koty Sharp points out to 2018 SURF undergrad Leah Hintz how a local coral species ingests microplastics.<\/figcaption><\/figure>\n

The local temperate coral Astrangia poculata<\/em> is an emerging model organism used to understand the microbiology of coral bleaching, a phenomenon that is directly caused by warming sea surface temperatures. Recent analyses of A. poculata<\/em> in our lab suggest that its microbiome exhibits an unusual level of stability and can recover from environmental disturbances such as extreme temperature fluctuations. Identification of the drivers of seasonal microbiome shifts can help further understand the significance of microbiomes to health and resilience to climate change in local organisms. More broadly, the succession patterns in A. poculata<\/em> microbiome recovery may translate to a deeper understanding of the role of microbes in resilience to climate change, and tropical coral disease and bleaching.<\/p>\n

In our lab, we use A. poculata<\/em> to test hypotheses about the fate and transport of plastics-associated microbes in Narragansett Bay benthic organisms, with a specific focus on the ability for microplastics-associated microbes to impact the health of the benthic organisms that incidentally co-ingest them.<\/p>\n

Students will work on two specific, closely related projects: 1) molecular analysis of microbiomes in laboratory and field-disturbed Astrangia poculata colonies; and 2) laboratory-based assays monitoring and tracking microplastics ingestion in A. poculata<\/em> with a variety of microbes and plastics types. Student researchers will gain experience with molecular biology and microbiology benchwork, sequencing analysis and bioinformatics, coral husbandry, and field sample collection and processing.<\/p>\n
