Not a 1-way street: Evolution shapes environment of Connecticut lakes
Date:5/22/2012

different gill structure, which make it easier for them to feed upon small plankton common in lakes. These evolutionary changes in the alewife also caused evolution in Daphnia, which no longer need to reproduce quickly in massive numbers. As a result, these lakes are more cloudy because water fleas eat less algae.

Here, evolutionary interactions between a predator and prey determine the ecology of these lakes, note the researchers.

"Natural selection favored survival of fish with smaller mouths and gills with filters more closely spaced that helped them harvest the smaller plankton," said Matthew R. Walsh, professor of ecology and evolutionary biology and lead author of the paper. "This, in turn, drove genetic changes in the rates of population growth of Daphnia, and these two changes then determine amount of algae present in lakes."

Post estimates these evolutionary changes in alewife probably happened within 50 to 100 years of the damming of the Connecticut lakes.
