Study identifies potentially invasive species for Florida
Study reveals next invasive species threat in FL
A Florida study revealed the next invasive species threats in the sunshine state.
TAMPA, Fla. – 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.”

Florida Aquarium offers free admission for military service members over holiday weekend
TAMPA, Fla. (WFLA) — Military service members can get free admission to The Florida Aquarium over Memorial Day weekend.
Active-duty military, veterans, retired military personnel, drilling reservists, National Guardsmen, and honorably or medically discharged service members will receive free general admission from Saturday, May 23, to Monday, May 25.
Military service members will need to show a valid U.S. Military ID or DD Form 214 to get a free ticket at the ticket window.
“In honor of the courage, commitment, and sacrifice of our nation’s military service members, The Florida Aquarium will once again offer complimentary general admission during Memorial Day weekend as a heartfelt thank-you to those who serve and have served our country,” the aquarium said.

Florida officials to pay $485,000 settlement to fired FWC biologist over Charlie Kirk post after his death
Florida officials will pay nearly half a million dollars to a biologist who was fired by a state agency for criticizing conservative activist Charlie Kirk on social media after his death.
The state’s Fish and Wildlife Conservation Commission fired biologist Brittney Brown in September after she reposted a meme on her personal Instagram account that claimed Kirk wouldn’t care about children being shot in their classrooms. She filed a lawsuit seeking reinstatement, saying she struggled to find other work because the state agency is the regulatory body for her research specialization in bird conservation.
Brown on Thursday signed a $485,000 settlement agreement with agency directors that covers back pay, damages and attorney costs. She agreed as part of the deal to not seek future employment at the agency.
Fish and Wildlife officials did not immediately respond to a request for comment.
Other workers also filed pending lawsuits over being fired over comments about Kirk’s assassination
Brown was among a wave of workers in both the public and private sector who lost their jobs over comments about Kirk’s assassination on a Utah university campus. Lawsuits are pending over many of those firings.
Before his death, Kirk and the organization he founded, Turning Point USA, galvanized the conservative youth vote to help President Donald Trump win a second term.
Kirk’s supporters combed social media after the Sept. 10 shooting for posts they viewed as celebrating his death. Influencers like Laura Loomer pledged to ruin the careers of people who made light of the killing, and the conservative social media account Libs of TikTok shared the identities and workplaces of many who posted with its audience of millions.
Libs of TikTok posted about Brown, and she was fired the next day, according to her lawsuit. Brown said someone then alerted Libs of TikTok about her termination only about 10 minutes after it happened and before it was made public.
In a rare instance in Tennessee, a retired police officer was jailed for 37 days over a Facebook post joking about Kirk’s assassination. Tennessee officials agreed Wednesday to pay $835,000 to settle a lawsuit filed by the man, Larry Bushart. While behind bars, Bushart lost his postretirement job and missed the birth of his granddaughter before authorities eventually dropped a felony charge against him, he said in the lawsuit.
Before her termination, Brown worked for Florida’s Fish and Wildlife Conservation Commission for about seven years and studied shorebirds and seabirds on the panhandle, according to court documents.
Carrie McNamara, an attorney with the ACLU of Florida, called Brown’s settlement deal “a hard-won vindication” that sends a message to Florida officials that they cannot punish speech they dislike.
“The First Amendment does not disappear when someone accepts a government job,” McNamara said.
Brown’s former supervisor at the agency, Habitat and Species Conservation Director Melissa Tucker, had claimed that Brown’s post generated hundreds of formal complaints and caused significant disruption. Discovery in the case later revealed that the agency only received about 50 complaints.
U.S. District Judge Mark Walker imposed sanctions against Tucker last week for exaggerating the amount and then not correcting the record.

Man who stabbed woman, her daughter to death in Coral Springs to be executed
A Florida man convicted of fatally stabbing of his cousin’s girlfriend and the couple’s 4-year-old daughter is set to be executed Thursday evening.
Richard Knight, 47, is scheduled to receive a three-drug injection starting at 6 p.m. at Florida State Prison near Starke. Knight was sentenced to death after being convicted of two counts of first-degree murder in 2006 for the deaths of Odessia Stephens and her four-year-old child, Hanessia Mullings.
This would be Florida’s seventh execution so far this year, following a record 19 executions in 2025. Republican Gov. Ron DeSantis oversaw more executions in a single year in 2025 than any other Florida governor since the death penalty was reinstated in 1976. The previous record was set in 2014 with eight executions.
According to court records, Knight had been living in Coral Springs, near Fort Lauderdale, with his cousin, his cousin’s girlfriend and their daughter in June 2000. Knight and Stephens frequently argued about Knight living there. One evening while Knight’s cousin was at work, Stephens told Knight that he would need to move out the next morning. Knight became angry and stabbed Stephens multiple times and then attacked the young girl, officials said.
While being held at the Broward County Jail following his arrest, Knight confessed the killings to another inmate, who testified against Knight during his trial.
The Florida Supreme Court denied Knight’s appeals last Friday. The court rejected his claim of newly discovered evidence, pointing out that an unidentified fingerprint found on a knife at the murder scene was known about and addressed during Knight’s original trial. The court also rejected claims based on Florida’s execution protocols and warrant process.
A final appeal was still pending before the U.S. Supreme Court.
A total of 47 people were executed in the U.S. in 2025. Florida led the way with a flurry of death warrants signed by DeSantis. Alabama, South Carolina and Texas tied for second with five executions each.
An execution was scheduled for Thursday in Tennessee. And another execution is planned in Florida on June 2. Andrew Richard Lukehart, 53, was convicted of fatally beating of his girlfriend’s infant daughter in 1996.
All Florida executions are carried out via lethal injection of a sedative, a paralytic and a drug that stops the heart, according to the Department of Corrections.
