Food webs

September 25, 2015 by Stacey Buckelew

Lower trophic level food web structure can be used as a metric of functional diversity and resiliency in an ecosystem. In AMBON, food web structure including phytoplankton, zooplankton, benthic invertebrates, and fishes is determined by using stable isotope analysis. We also aim to get a better understanding of the role of microbes within this food web. [AMBON scientists: Katrin Iken, Bodil Bluhm; research associate: Ann-Christine Zinkann]

AMBON Study Area

A team of multi-disciplinary scientists are monitoring marine biodiversity in the U.S Arctic waters of the  Chukchi Sea. The  study stations (red circles) are shown together with the main water mass flow (arrows).

Arctic Ecosystem

The Arctic ecosystem has 3 main ecosystem realms: the sea ice provides habitat for small organisms and supports larger megafauna; the pelagic system includes both important primary producers and grazers; and the well-developed benthic system helps drive a complex food web.
