attribute NC_GLOBAL acquisition_description String Field experiment on artificial patch reefs to test for effects of\\u00a0\ninvasive red lionfish density on native coral-reef fishes. Four reefs were\nused as 0-lionfish control reefs and there was one reef per remaining lionfish\ntreatment (2, 4, 6, 8, 10, and 12 lionfish/m2). Using SCUBA and handnets, we\ncollected lionfish ranging in initial size from 40 to 71mm total length [TL]\nfrom nearby reefs.\\u00a0 Each lionfish was given a unique elastomer tag\n(Northwest Marine Technology Inc., Shaw Island, WA, USA) to differentiate\nbetween lionfish at the start of the experiment and any new immigrants over\nthe course of the study and to monitor demographic rates as part of another\nstudy (see related files and references). Treatments were started on all reefs\nwithin a 2-week period. To maintain treatments, we monitored lionfish density\nduring weekly visits and removed any new lionfish recruits (total of 15\nthroughout experiment) and immigrants (total of 5 throughout experiment). In\naddition, we removed resident native piscivores and standardized the number of\nNassau grouper (Epinephelus striatus) and territorial damselfishes (Stegastes\nspp.) weekly to mitigate any confounding effects of these strong interactors\non fish recruitment. Of the lionfish initially placed on the reefs, only 6 out\nof 40 disappeared. To account for the small changes in lionfish density\nthroughout the experiment, we averaged the weekly lionfish densities on each\nreef over the course of the experiment (1, 2, 4, 7, 10, and 12 lionfish/m^2).\n \nFollowing the establishment of lionfish density treatments, a pair of divers\nusing SCUBA censused the entire fish community on each reef weekly for 7\nweeks, recording the species, abundance, and body size (TL estimated to the\nnearest centimeter) of all fish present both on the reefs and within a 1-m\nradius around the reefs. Divers slowly approached the reefs and first counted\nall planktivorous and active species hovering above the reefs from a distance\nof approximately 3 m. From a distance of 1 m, the divers slowly circled the\nreefs and counted all other species, using dive lights to count cryptic\nspecies in holes.\n \nAll data were entered by one person, and then subsequently checked by another\nperson 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.\nThe 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?
