H.Baumann was invited to be one of four panel speakers during a session called “Acidifying our Estuaries – Global Problems, local effects” chaired by Dr. Denise Breitburg (SERC) during the “7th National Summit on Coastal and Estuarine Restoration” in Washington D.C. (1-5 November 2014, Gaylord Hotel & Convention Center). The talk covered recent results from work on early larval silversides and bivalves, showing that the combined negative effects of acidification and hypoxia need to be better understood and can at times be greater than additive (i.e., synergistic).In biology, sometimes 1 + 1 is greater than 2.
