Kelp forests are dynamic ecosystems that provide crucial habitat for a myriad of species across all trophic levels of coastal food webs, including gray whales on the Oregon coast. Gray whales forage heavily in kelp-dominated reefs where high abundances of their zooplankton prey are found. However, kelp forests have been declining along the US West Coast coincident with increases in purple sea urchin populations. Are these changes happening on the Oregon coast and are higher trophic levels, like gray whales, affected? Come hear about the research that a team of Oregon State University researchers to answer these questions.
