Colonization of New Substrates by Aquatic Insects and Snails
This experiment examines colonization of new substrates by aquatic insects and snails.
Oak Creek Snails
Trays filled with stream sediment will be placed in the channel for colonization by stream invertebrates. Snail densities in each tray will be manipulated to test the effect of snails on the abundance of other stream invertebrates. One half of the chann
