Oil spills and other contaminants can stress biologic life, sometimes affecting mutation rates and reproductive parameters that can affect fitness (ability to survive and reproduce). The sensitivity of red mangrove to historic stress events was determined by comparing the frequency of trees producing albino propagules in previously-contaminated and uncontaminated forests in Tampa Bay.

Contaminated sites demonstrated higher rates of mutations than uncontaminated sites. Collecting data on mutation rates for a number of mangrove forests within an estuary is important because it provides background data that can be used as a metric by which to gauge recovery from a pollution event or to assess future environmental change.

These data sets are in ArcGIS Shapefile format. To view these files, you must have ESRI ArcGIS Software or other GIS software. A freely available lightweight version of ESRI's software is ArcGIS Explorer.
