Mary Beth Decker

Mary Beth Decker is a Biological Oceanographer and Ecologist specializing in the influence of ocean conditions on the distribution, abundance, and behavior of marine predators. Mary Beth works on plankton-consuming predators of the Bering Sea ecosystem, in particular jellyfish and forage fish. She is particularly interested in how climate variability influences jellyfish populations, and how jellyfish blooms in turn affect food webs via predation and competition. She teaches three courses at Yale: Biological Oceanography, Coastal Ecosystems in a Changing World, and Caribbean Coastal Development.
