Fish forced into the ‘foraging arena’ when lakes lose their trees

Adam Hinterthuer, writing for University of Wisconsin-Madison:

As water levels drop and submerged trees rise above the waterline, some fish are forced into the "foraging arena" to face predators

In attempts to predict what climate change will mean for life in lakes, scientists have mainly focused on two things: the temperature of the water and the amount of oxygen dissolved in it.

But a new study from University of Wisconsin-Madison researchers is speaking for the trees — specifically, the dead ones that have toppled into a lake’s near shore waters.

For fish in northern Wisconsin lakes, at least, these trees can be the difference between pastures of plenty and the Hunger Games.

Interesting study from the Center of Limnology.
