Poster session: “Ocean Acidification and Lower Trophic Levels: Identifying the Knowledge Gaps”, 2015 Aquatic Sciences Meeting, 22-27 February 2015, Granada, Spain

The abstract submission deadline is 23:59 U.S. Central Daylight Time on Friday, 10 October 2014.

Ocean acidification will have dramatic impacts on phytoplankton assemblages in coastal and oceanic environments, with potential winners and losers. However, the outcome remains uncertain because we have little understanding of the physiological and ecological drivers of this change. The direct effects on phytoplankton may include impacts on carbon and macronutrient acquisition, trace metal availability, or cytosolic and metabolomic modifications, all potentially leading to subtle-to-dramatic alterations of phytoplankton growth rates, physiological health, and nutritional quality. In addition, it is unclear to what extent trophic interactions such as top down processes (grazing or facultative mixotrophy), or bacteria- phytoplankton associations, modify or shape the phytoplankton community structure under the new more acidic regime. We propose a poster session that encourages individuals to identify and discuss knowledge gaps in the broad aspects of ocean acidification and lower trophic levels.
