Contents Notes
The Environmental Requirements and Pollution Tolerance (ERAPT) system is a computerized retrieval and analysis system for environmental information on aquatic organisms. It can be used to predict organism assemblages based on environmental conditions, to describe environmental characteristics associated with plants and animals which inhabit specific sites, and to compare site characterizations with associated biological communities for inconsistencies resulting from organism misidentification or erroneous habitat information. It can also identify species which are particularly sensitive to specific sets of environmental conditions and can predict changes in species composition which are likely to result from environmental disturbance.
