'Little janitor' merits attention in Florida springs' health debate, UF/IFAS research shows

Published July 28, 2014
Although the blame for algae-choked springs is often pinned on excess nitrate, the scientists say the absence of algae-eating native freshwater snails known as Elimia — which UF researcher Dina Liebowitz calls the “little janitor of the springs” — may be a key factor.

Among the study’s strongest findings, outlined in a paper posted online this month by the journal Freshwater Biology, was a strong negative correlation between snails and algae, Liebowitz said: Where they found more snails, in general, there was less algae.

Federal officials may take manatees down a notch on endangered species list

Posted 7/1/2014
Federal officials announced Tuesday that they have agreed to consider removing Florida manatees from their list of endangered species. Instead, they said, the iconic mammals — which have been on the list since it was created in 1967 — may belong in the less protective "threatened" category, even though the number of manatees killed last year set a new record.

Manatee mortality
Total manatee deaths in the past five years:
2009: 429
2010: 766
2011: 453
2012: 392
2013: 829
