State’s tweaked vacation-rental plan advances
“I want my research to have an impact on people. Ctenophores are perfect for this because we can use these apparently ‘simple’ animals for insights into environmental challenges and into human health.”
At the heart of the legislative wrangling is over whether the state or local governments should regulate the rentals. DARA KAM NEWS SERVICE OF FLORIDA

A controversial proposal dealing with vacation rentals underwent a major overhaul on Thursday, March 11, after the bill sponsor stripped out a provision that would have blocked local governments’ ability to license and inspect the properties. The fight about oversight of short-term rentals has escalated in the Legislature as the popularity of vacation properties advertised on platforms such as Airbnb has mushroomed. At the heart of the legislative wrangling is an effort to “preempt” regulation of short-term rental properties to the state, a move that draws vehement opposition from city and county officials because it would take away local authority. Sen. Manny Diaz Jr., R-Hialeah, filed a proposal (SB 522) in January that included requiring online platforms to collect and remit taxes on vacation rental proper-

tenophores, or comb jellies, might not look like much. Picture a translucent gelatinous orb about the size of a golf ball, strung with a kaleidoscope of wriggling colors refracting light. Now imagine the comb jelly being cut in half and then having both halves grow back, good as new. This regenerative ability may sound like science fiction, and for you and me it is (at least for now). But to these “simple” animals, regeneration after an injury is part of everyday life.
You might mistake these creatures for jelly fish — you may have seen them floating in the Matanzas Inlet near the Palm Coast Marina. At least that’s where Dr. Allison Edgar goes to catch Mnemiopsis leidyi, aka the warty comb jelly or the sea walnut. Edgar is a post-doctoral scientist at the Whitney Laboratory for Marine Bioscience, a research institute of the University of Florida on the border of Flagler and St. Johns counties. She researches evolution by comparing the development and regeneration of Mnemiopsis and Beroe ovata, a member of the so-called cigar comb jellies. Her research is funded by the National Science Foundation. Edgar’s most recent project started when she noticed that some Mnemiopsis could spawn and produce offspring several months earlier in their life cycle than previously reported. This would be like discovering your dog could produce a litter of puppies just weeks after it was born. Intrigued, Edgar asked her lab mates to help her brainstorm possible variables that could explain her observation. Someone mentioned that the air conditioner had broken down, leaving the lab unusually warm. Knowing that temperature influences the reproduction of other sea creatures, Edgar designed experiments controlling for temperature extremes. While her results suggest that Mnemiopsis yield more offspring at higher temperatures, temperature alone SEE COMBING PAGE 4
