It is well established that protistan predation can be a significant source of mortality for bacteria and phytoplankton. Grazing protists in turn are a significant food resource for metazooplankton, and through the excretion of nitrogen and phosphorus compounds, they play a significant role in the release of regenerated nutrients. Despite decades of studies on protistan grazing, knowledge gaps exist with respect to their abundance, distribution, seasonality, prey selectivity, and co-occurrence patterns. This project builds upon an ongoing time series (with hourly resolution since 2006) by the Staining IFCB at the Martha\u2019s Vineyard Coastal Observatory (MVCO) and will be the first to conduct long-term, high-resolution, automated measurements of grazer communities <em>in situ<\/em> to yield both morphologic and genetic information about the organisms present and their interactions with prey.<\/p>\n<h3>Funding Agencies<\/h3>\n<p>The National Science Foundation under grant number OCE-1434440 funded this research.<\/p>\n<p><a href=\"http:\/\/www.nsf.gov\"><img loading=\"lazy\" src=\"https:\/\/www2.whoi.edu\/templates\/wp-content\/uploads\/2016\/09\/nsf.png\" alt=\"nsf\" width=\"100\" height=\"100\" \/><\/a><\/p>\n<h3>Partners\/Collaborators<\/h3>\n<p>This is a collaborative project with Dr. Heidi Sosik and Dr. Robert Olson.\u00a0 Dr. Emily Brownlee (a MIT\/WHOI Joint Program Graduate student) conducted her thesis research as part of this grant.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Dynamics of Protistan Grazers Dynamics of protistan grazers: diversity, abundance and prey relations Protists are important as both primary producers and consumers in aquatic microbial ecosystems.
