Study identifies potentially invasive species for Florida


University of Florida scientists led a study aimed at identifying potentially invasive species for the state.

The team of experts, which included researchers, agencies, and nonprofit organizations, studied 460 species. Creatures were given a score based on their likelihood of establishment and spread in the state. The experts also factored in the species’ potential to negatively affect the ecosystem and economy.

“If we could stop them before they got established, we could save a lot of money and protect the habitats,” lead scientist Dr. Deah Lieurance, who is now an assistant professor of invasive species, biology, and management at Penn State University, said. “We have pretty unique ecosystems in Florida we’d like to try to keep as pristine as possible.”

The following are species the study targeted as being potentially invasive in Florida:

ALEWIFE FISH 

According to the United States Geological Survey (USGS), the alewife is a small herring that can restructure a lake’s food web, leaving less food for native species.

“It can have some big-picture effects on the ecosystem,” Lieurance said.

ZEBRA MUSSELS

Zebra mussels are one of the most troublesome invasive species in North America, according to the Florida Fish and Wildlife Conservation (FWC); The agency describes them as “common hitchhikers on boats, fishing equipment and aquarium plants.”

In addition, zebra mussels can be found in moss balls, which are a rare form of algae that some people use to filter water in aquariums.

The FWC issued a warning about moss balls and their danger to the ecosystem in 2021. 

RED SWAMP CRAYFISH

According to USGS, “the red swamp crayfish is readily available through the biological supply trade and may be released following classroom or laboratory use.”

“We had quite a few crayfish that made the top 40 list,” Lieurance said.

CRAB-EATING MACAQUE MONKEYS

“This was my surprise species,” Lieurance said. “They do eat crabs, as their name implies, but they’re also a very close relative to the macaques that we already have here in Florida.”

It’s one reason why these monkeys got the highest possible ranking for the likelihood of invasion and threat to human health.

Crab-eating macaque monkeys are related to the rhesus macaque monkeys. Some rhesus macaque monkeys found in Silver Springs State Park in Marion County were found to carry the herpes virus.

“I think the biggest value in this study is to bring awareness to invasive species and the potential to have even more,” Lieurance said. 

She suggests conducting a study like this one every five years.

“Big picture globally, we’re losing about $419 billion per year to invasive species,” Lieurance, who is currently working on projects in Puerto Rico and the U.S. Virgin Islands, said. “Repeating this process on a regular basis can keep us ahead of the game when it comes to managing invasive species.”

Cocaine, guns reported found after gas station surveillance in Florida

Cocaine, guns reported found after gas station surveillance in Florida


A 37-year-old man was jailed June 29 after Port St. Lucie Police reported finding nearly 5 ounces of cocaine, other drugs and firearms at his home, according to an affidavit.

Wallick Cooper, of the 800 block of Southwest Monica Street in Port St. Lucie, was arrested on charges including a single count of cocaine trafficking; two counts of possession of controlled substance without prescription; and three counts possession of firearm or ammunition by a felon.

Police conducting surveillance June 25 at a gas station in the 300 block of Southwest Port St. Lucie Boulevard reported a Mercedes-Benz arrived and backed in. Detectives reported seeing a suspected drug transaction between the driver and a man who approached the driver’s window.

Investigators stopped the Mercedes after it left, alleging the window tint was illegal. Cooper, the only occupant, reportedly “immediately began lying about where he was coming from and where he was heading,” an affidavit states.

He let police search the vehicle. They found no drugs but turned up about $1,000 they suspected came from drug sales, though Cooper “smirked and denied accusations,” the affidavit states.

Cooper was released from the scene.

Police told his probation officer about the encounter, and the probation officer on June 29 reported finding suspected drugs in Cooper’s home.

Ultimately, police got a search warrant, and they reported finding about 4.92 ounces of cocaine; about 12.9 ounces of marijuana; three firearms; and a small amount of pills.

Cooper has a medical marijuana card, but hadn’t gotten pot since February, according to police. Police reported the recovered marijuana wasn’t packaged “consistent with legally possessed marijuana.”

Cooper was held July 1 in the St. Lucie County Jail on no bond, a jail official said.

Kids with autism are prone to drowning. Florida is trying to prevent that


Garland Jones, recreational therapist and senior program director of the YMCA of South Florida’s special needs program, teaches Mackenzie Wesley, 5, to breathe safely in water by using a ping pong ball as a visual aid.

WESTON, Fla. — Mackenzie Wesley sports a big grin and bright blue Lilo & Stitch swim gear as she runs into her weekly swim lessons. It’s fitting, because the 5-year-old has something in common with movie character Lilo: She adores water.

“Whether it’s the pool or beach, she enjoys it fully,” says her dad Steven Wesley.

Mackenzie isn’t alone: Many kids with autism share a natural love for water because it can be sensory bliss — the feeling on their skin, the pressure and the sparkle of the water can all be soothing. Lucky for her, Mackenzie lives here, less than an hour outside of Miami in a state that’s dotted with bodies of water.

But there’s a tragic reality tied to that fact, as Mackenzie’s mom, Brittany Bucknor, is all too aware. “In Florida, there’s water everywhere, and also with kids her age, and also just being on the spectrum, it’s a very — way higher — rate of having an incident of drowning.”

Kids with autism are 160 times more likely than other children to die from drowning, according to a seminal 2017 study from Columbia University. In fact, in Florida, most children drown in backyard pools. That’s largely because about half of autistic children have a tendency to wander from safe settings. That fact, combined with an attraction to water can make for a dangerous combination. Quality swim lessons can help.

That’s one of the reasons Mackenzie’s parents enrolled her in Swim Buddies, the YMCA of South Florida’s low-cost program aimed at children with disabilities. It’s also why the state of Florida, which has one of the highest childhood drowning rates in the nation, is expanding a voucher program on July 1 that will put children ages 1-7 who have autism at the front of the line for subsidized swim lessons. “We have tragic circumstances and stories across the state of Florida of young children with autism that are wandering away, they’re eloping from their homes, from their classrooms,” says Florida state Rep. Anna Eskamani, a Democrat, and one of the lawmakers who sponsored the bipartisan bill that changed the state’s swim vouchers.
