attribute	NC_GLOBAL	acquisition_description	String	Field experiment on artificial patch reefs to test for presence of density dependence in invasive red lionfish recruitment, immigration, loss, and growth (in mass and length).\u00a0 Juvenile lionfish (40 - 71 mm total length [TL]) were collected from surrounding reefs by SCUBA divers using handnets and held in 190-l flow-through aquaria prior to release onto the experimental matrix. All lionfish were tagged subcutaneously using colored elastomer (Northwest Marine Technology Inc., Shaw Island, Washington, USA) on the caudal peduncle and/or slightly anterior to the caudal peduncle just under the dorsal fins.\u00a0 All fish were held for at least 12 hours after tagging to allow for recovery from any tagging effects and measured (TL to nearest 1 mm) and weighed (wet weight [WW] to nearest 1 mg) just before being released onto the experimental reefs.\u00a0 Lionfish were transplanted to 10 artificial patch reefs (each measuring 1 cubic meter) so that 4 reefs had 0 lionfish on them (controls) and 6 each had a unique density of lionfish (2, 4, 6, 8, 10, or 12 lionfish).\u00a0 To account for changes in lionfish density throughout the course of the experiment, we also calculated the weighted average weekly lionfish density for each reef (1, 2, 4, 7, 10, and 12 lionfish/m^2 rounded to the nearest fish). A pair of trained observers using SCUBA recorded the number and identity of tagged lionfish present on each reef weekly.\u00a0 If a lionfish was not seen on a reef, we searched the surrounding sand and seagrass for approximately 10 minutes. If the lionfish was still not found, it was marked as absent for that week. If never found again, it was marked as lost from the last day it was seen.\u00a0 We recorded the number of new lionfish recruits present on each reef weekly.\u00a0 Any new lionfish were immediately removed to preserve the treatment densities.\u00a0 Every two weeks, we recaptured all tagged lionfish on scuba using handnets, re-measured their TL in situ, and immediately released them back to their original locations on the reef. At the conclusion of the experiment (after 8-weeks), lionfish were re-captured and re-weighed. All data were entered by one person, and then subsequently checked by another person to ensure accuracy.\u00a0

attribute	NC_GLOBAL	projects_0_description	String	The Pacific red lionfish (Pterois volitans), a popular aquarium fish, was introduced to the Atlantic Ocean in the vicinity of Florida in the late 20th century. Voraciously consuming small native coral-reef fishes, including the juveniles of fisheries and ecologically important species, the invader has undergone a population explosion that now ranges from the U.S. southeastern seaboard to the Gulf of Mexico and across the greater Caribbean region. The PI's past research determined that invasive lionfish (1) have escaped their natural enemies in the Pacific (lionfish are much less abundant in their native range); (2) are not yet controlled by Atlantic predators, competitors, or parasites; (3) have strong negative effects on populations of native Atlantic fishes; and (4) locally reduce the diversity (number of species) of native fishes. The lionfish invasion has been recognized as one of the major conservation threats worldwide. The Bahamas support the highest abundances of invasive lionfish globally. This system thus provides an unprecedented opportunity to understand the direct and indirect effects of a major invader on a diverse community, as well as the underlying causative mechanisms. The PI will focus on five related questions: (1) How does long-term predation by lionfish alter the structure of native reef-fish communities? (2) How does lionfish predation destabilize native prey population dynamics, possibly causing local extinctions? (3) Is there a lionfish-herbivore-seaweed trophic cascade on invaded reefs? (4) How do lionfish modify cleaning mutualisms on invaded reefs? (5) Are lionfish reaching densities where natural population limits are evident?
