Methods - A summary
For a more detailed description of the methods, please look at the subpages.
Behavior
In two different setups the activity of the isopods was measured with and without cues from either damselfly larvae or perch.
Size
Groups of isopods were subjected to predation from perch or damselfly larvae in different substrate (see Fig 1). Each group consisted of only one ecotype. The mean size in each group was examined befor and after the predation trial.
