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.
