The manatee mortality database is now available on the web site of the Florida Fish & Wildlife Conservation Commission's Florida Marine Research Institute (FMRI). In addition to the monthly mortality tables already available on the web site, the new database enables the user to search for manatee mortality information by county, cause of death and date from 1974 through 2001. Two report formats are available: A 'summary' report which lists the search results in a numbers-only table, and an 'individual' report which provides more detailed information such as sex, size, region and cause of death. You can find the new manatee mortality search on the FMRI web site at http://www.floridamarine.org/manatees/. |
