Over the last 30 years, urbanization has increased along the Indian River Lagoon, which stretches about 250 kilometers on Florida s east coast. As a result, water quality has deteriorated and there is widespread loss of seagrasses and persistent harmful algal blooms, which threaten ecological, human and marine animal health, such as manatees. In this valuable and vulnerable system, two types of toxic blooms raise significant concerns: Microcystis aeruginosa (blue-green algae known to produce microcystin toxin) and Pyrodinium bahamense, which produce a neurotoxin called saxitoxin. Saxitoxin causes paralytic shellfish poisoning, which has caused dozens of fatal and non-fatal poisonings worldwide. Specific health effects due to concentrations of toxins in surface water of the Indian River Lagoon are not fully understood. Researchers from Florida Atlantic University s Harbor Branch Oceanographic Institute in collaboration with the St. Johns River Water Management District coll ....
Hurricane season has now started and while communities in Florida prepare for the next devastating storm, there is also money being set aside to help them get ready for future impacts caused by sea level rise, intensified storms and flooding. Gov. Ron DeSantis signed Senate Bill 1954 (Statewide Flooding and Sea Level Rise Resilience) into law in May. The bill received unanimous approval in both the Florida House and Senate as both Republicans. ....
Conservationists patted each other on the back for the success. It was short-lived. Two years later, more than half the grass was gone. Much of Florida s seagrass would die post 2011. Extreme weather and storm runoff fed algae blooms that harmed seagrass beds along the Panhandle, Big Bend, southwest Florida, and along the east coast from Biscayne Bay to the northern Indian River Lagoon. Here on the Space Co, drought, then extreme cold, set the stage for severe algae blooms that killed off 60% of the lagoon s seagrass, a consortium of 26 scientists concluded in 2015. While runoff often delivers the nitrogen and phosphorus that trigger algae blooms, drought preceded the massive lagoon algae blooms that began in late 2010. ....
