attribute NC_GLOBAL acquisition_description String During the summer of 2012, a field experiment was conducted on 14 isolated\npatch reefs near the Cape Eleuthera Institute, Eleuthera, Bahamas. Reefs were\npaired into blocks by location, size, depth, and vertical relief so that reefs\nin each block demonstrated similar environmental characteristics. Reefs were\nthen randomly assigned to one of two lionfish treatments:\\u00a0 low lionfish\nreefs (where divers regularly removed lionfish), and high lionfish reefs\\u00a0\n(where lionfish were added to maintain differential lionfish densities. At\neach reef, the investigator selected two isolated populations of fairy basslet\non small ledges sufficiently separated from each other and from other suitable\nbasslet habitat to inhibit emigration or immigration. Populations were then\nrandomly assigned to either receive artificially increased recruitment or\nremain unmanipulated. Following the establishment of treatments, the\ninvestigator returned to census each population after two days, four days and\nweekly thereafter, with a final census after four weeks. During each census,\nthe investigator recorded the size of each basslet (adult and juvenile), the\ntotal population size, any predators within 2-m of the target basslet ledge,\nand whether those predators where actively hunting among the experimental\nbasslet populations.

attribute NC_GLOBAL project String Lionfish Invasion
attribute NC_GLOBAL projects_0_acronym String Lionfish Invasion
attribute NC_GLOBAL projects_0_description String Invasive species are increasingly introduced by human activities to new regions of the world where those species have never existed previously. In the absence of natural enemies (predators, competitors, and diseases) from their homeland, invasives may have strong negative effects on invaded ecosystems, especially systems with fewer species (\"ecological release\"), and may even drive native species extinct. However, if native natural enemies can somehow control the invaders (\"ecological resistance\"), then ecological disruption can be prevented or at least moderated. Most of the many invasive species in the sea have been seaweeds and invertebrates, and the few documented invasive marine fishes have not caused major problems. However, this situation has recently changed in a stunning and ominous way. In the early 1990s, lionfish (Pterois volitans) from the Pacific Ocean were accidentally or intentionally released from aquaria to the ocean in the vicinity of Florida. Camouflaged by shape and color, protected by venomous spines, consuming native coral-reef fishes voraciously, and reproducing rapidly, lionfish have subsequently undergone a population explosion. They now range from the mid-Atlantic coast of the US to the Caribbean, including the Bahamas. Native Atlantic fishes have never before encountered this spiny, stealthy, efficient predator and seldom take evasive action. In fact, the investigator has documented that a single lionfish is capable of reducing the abundance of small fish on a small coral patch reef by nearly 80% in just 5 weeks. There is great concern that invasive lionfish may severely reduce the abundance of native coral-reef fishes important as food for humans (e.g., grouper and snapper in their juvenile stages) as well as species that normally maintain the integrity of coral reefs (e.g., grazing parrotfishes that can prevent seaweeds from smothering corals). There are far more species of coral-reef fish in the Pacific than the Atlantic, so this invasion may represent a case of extreme ecological release with minor ecological resistance. Dr. Hixon and colleagues will study the mechanisms of ecological release in lionfish, as well as examine potential sources of ecological resistance in the heavily invaded Bahamas. Because very little is known about the ecology and behavior of lionfish in their native Pacific range, he will also conduct comparative studies in both oceans, which may provide clues regarding the extreme success of this invasion. In the Bahamas, the investigator will document the direct and indirect effects on native species of the ecological release of lionfish, both as a predator and as a competitor. These studies will be conducted at various scales of time and space, from short-term experiments on small patch reefs, to long-term experiments and observations on large reefs. Whereas direct effects involve mostly changes in the abundance of native species, indirect effects can be highly variable. For example, lionfish may actually indirectly benefit some native species by either consuming or outcompeting the competitors of those natives. The project will explore possible ecological resistance to the invasion by determining whether any native Bahamian species are effective natural enemies of lionfish, including predators, parasites, and competitors of both juvenile and adult lionfish. Comparative studies of natural enemies, as well as lionfish ecology and behavior, in both the Atlantic and the Pacific may provide clues regarding the explosive spread of lionfish in the Atlantic.\nRegarding broader impacts, this basic research will provide information valuable to coral-reef and fisheries managers fighting the lionfish invasion in the US, the Bahamas, and the greater Caribbean, especially if sources of native ecological resistance are identified. The study will fund the PhD research of U.S. graduate students, as well as involve assistance and participation by a broad variety of undergraduates and reef/fisheries managers, including women, minorities, native Bahamians, and native Pacific islanders. Participation in this project will promote education in marine ecology and conservation biology directly via Dr. Hixon's and graduate students' teaching and outreach activities, and indirectly via the experiences of undergraduate field assistants and various associates.
