In this week’s Gulf Stories Moment, Dr. Alexis Janosik, assistant professor from the Department of Biology at the University of West Florida, discusses using environmental DNA to show evidence of lionfish in rivers and estuaries.
Lionfish have long been a prodigious threat to native species in the Gulf of Mexico, taking a big bite out of the region’s vital ecosystem as well as its economy.
However, the invasive species are not just doing harm in the warm waters of the Gulf. They have also moved into the mouths of local river systems, a researcher at the University of West Florida has discovered.
“Those are big nursery grounds for juvenile (native species of fish), a lot that are economically and ecologically important here,” said Amy Brower, a graduate student in the Department of Biology.
In this week’s Gulf Stories Moment, Dr. Alexis Janosik, assistant professor from the Department of Biology at the University of West Florida, discusses the population genetics of crabs and snapping shrimp from artificial reefs.
– A University of West Florida professor will travel with a team of international scientists to Antarctica to study how marine animals that live near the seafloor are being affected by climate change.
Dr. Alexis Janosik, an assistant professor in the Department of Biology, will leave Nov. 16 to sail with the British Antarctic Survey. She will spend almost a month on the research ship RRS James Clark Ross. Janosik will be the only researcher from the U.S. to take part in the research cruise.
