New Lionfish Invasion Updates

A note from Dr. Mark Hixon (pasted below) updating his lab’s lionfish research. In addition to the papers he highlights, there are are also some interesting findings regarding lionfish parasite release in the invaded range and how lionfish may disrupt fish cleaning stations.

“Now that my lab’s lionfish research is winding-down, I’ve finally updated our lionfish invasion web page, which includes reprints of all our publications, a poster, videos, and more:

I hope you find this resource to be useful, and I encourage you to share it with others interested in this invasion.

Most of our studies focused on two questions:  (1) Do native species offer any biotic resistance to the invasion?  (short answer:  not much)  (2) What are the ecological effects of the invasion?  (short answer:  many, both direct and indirect)

From a management perspective, two of our papers are probably the most important.   Wilcox and Hixon (2105) show that there are likely false positives in ciguatera tests of lionfish, the easy solution being to test the flesh after cooking.  Benkwitt et al. (2017) provide evidence that the invasion is starting to wane in the Exumas, as well as hypotheses regarding why.”

Craig Layman
My lab’s interdisciplinary pursuits provide for a multi-faceted understanding of environmental change in the coastal realm. We are ecologists, asking questions that span population, community, ecosystem and evolutionary sub-disciplines. We often use a food web based perspective, exploring top-down (e.g., predation) and bottom-up (e.g., nutrient excretion) mechanisms by which animals affect ecosystem processes. All of our efforts are framed within a broader outreach framework, directly integrating science and education, using approaches such as this website.
