Figure 4-1. Graphs showing spikes in enzyme activities at the transitional sites. Mean
 enzyme activities have been normalized for visual comparison. Ec and En,
 normalized glucosidase and leucine aminopeptidase activities exhibited the
 largest spikes in the benthic layer while En and Ep phosphatasee)
 exhibited the largest in the soil layer. Bars represent standard errors.
