One unexpected player in Florida’s ecosystem is the Peter’s rock agama, a nonnative lizard introduced to South Florida in 1976. It hails from East Africa and arrived partly due to the pet trade, as some were either released or escaped from homes. While these lizards thrive in the southern part of the state, they’re starting to show up in northern regions too.
Recent research from the University of Florida has raised some eyebrows. Scientists are exploring whether these agama lizards are linked to an increase in mosquito-borne illnesses among humans. Nathan Burkett-Cadena, an associate professor at the UF/IFAS Florida Medical Entomology Laboratory, has some intriguing insights.
Burkett-Cadena explains that when mosquitoes bite lizards like the agama, they miss opportunities to bite birds or humans. Birds are known hosts for several harmful viruses, so the presence of agama lizards could theoretically reduce the spread of certain diseases.
However, there’s a twist. The agama lizards might also lower the population of the brown anole, another lizard in Florida. This might leave more mosquitoes available to bite humans and other animals, like birds, which could then carry viruses.
Overall, while agamas may not drastically impact Florida’s environment, their presence complicates the public health picture. It’s a reminder of how interconnected our ecosystems are and how introducing one species can ripple through many others. Experts emphasize that as we continue to study these lizards, monitoring their effects on both local wildlife and human health remains essential.
This insight comes at a relevant time. Data from the Florida Department of Health indicates a slight uptick in reported mosquito-borne illnesses. Staying informed about these changes can help us understand the role of species like the Peter’s rock agama in our health landscape.
