Researchers are exploring links between evolution and ecology in a number of different settings, documenting interconnections that extend down to genetic changes. One notable example focuses on how the alewife, a fish that lives in lakes in eastern North America, shapes and is shaped by its freshwater ecosystem. The researchers have shown how these so-called eco-evo effects can ripple across a food web in unexpected ways.
