Recent Research Projects with Undergraduates

Summer / Fall 2008:

• A mark-recapture study of lsalamander density in the presence and absence of fish

• The nighttime feeding behavior of trout and larval salamanders

Spring 2008:

• The behavioral antipredator response of stream invertebrates to fish and salamanders

• Causes of changing Paroxetine concentrations in aquatic experiments in the laboratory

Earlier projects at King's College:
