ecosystem

An illustration of the (A) pre-whaling and (B) post-whaling interactions between whales, shrimp-like krill (pink), and photosynthesizing organisms known as phytoplankton (top left of each panel) in the Southern Ocean. The decimation of whales in this ecosystem and coincident drop in krill in some former whaling grounds implies a large shift in the amount of iron available due to the loss of whales and thus micronutrients in whale poop (lower left).

Researchers Courtney Duchardt, right, then a UW Ph.D. student, and David Augustine, of the U.S. Department of Agriculture, examine a mountain plover in the Thunder Basin National Grassland. Mountain plovers, a bird that thrives when vegetation is kept shorter by prairie dogs, almost disappeared from the study area when plague decimated prairie dog numbers in 2017.
