attribute NC_GLOBAL acquisition_description String We conducted all experimental trials in 50 gallon (ca. 190 l) acrylic aquarium\ntanks (91.5 \\u00d7 38 \\u00d7 51 cm) with continuous flow-through seawater\nsystems. Food was withheld from predators for 24 h prior to observation to\nensure predator response to the presence of prey. Tanks were divided in half\nwith a removable central barrier of solid aluminum (Fig. 1). We released a\nsingle predator into one side of the tank and placed 2 basslets in the other\nside. Basslets were held in identical small glass containers (~500 ml) with\nmesh covers (1 basslet per container) positioned in each corner of the tank.\nThese prey containers ensured that predators were able to receive both visual\nand chemical cues from basslets, but could neither make physical contact nor\nconsume any basslets.\n \nTo determine whether the preference of predators for basslets was driven by\nbasslet species (fairy and blackcap) or basslet size (small and large:\n1.7\\u20132.5 and 3.5\\u20135.2 cm TL, respectively) we presented pairs of\nbasslets in cross-factored combinations of the 2 variables, resulting in the\nfollowing treatments: (1) small fairy and large fairy, (2) small blackcap and\nlarge blackcap, (3) small fairy and small blackcap, (4) large fairy and large\nblackcap, (5) small fairy and large blackcap, and (6) large fairy and small\nblackcap. In addition to randomizing the order of basslet treatments presented\nto each predator, we also randomized the corner of the tank basslets were\nplaced in every time a treatment was presented.\n \nOnce the predator and basslets were in their respective sides of the tank, we\nallowed them to acclimate for 20 min, after which we removed the central\nbarrier and observed the predator\\u2019s behavior for 10 min. Observations\nwere performed either in person (74 lionfish trials; 73 graysby trials) or\nfilmed with a digital video camera (16 lionfish trials; 17 graysby trials)\npositioned outside of the tank. During each 10 min trial, we recorded (1)\nwhich basslet the predator hunted first (initial hunting preference); (2) the\nnumber of times the predator\\u2019s mouth made physical contact with each\nglass container (number of strikes); and (3) the amount of time the predator\nhunted each basslet (hunting time). We defined the hunting behavior of\nlionfish as occurring when an individual directly faced a basslet with flared\npectoral fins and/or blew pulsed jets of water towards a basslet (Cure et al.\n2012). We characterized graysby hunting behavior as occurring when an\nindividual positioned itself near a basslet (<10 cm in this experiment) while\ndirectly facing the basslet (Webster 2004).\n \nAt the conclusion of the 10 min trial, we separated the predator from the\nbasslets and placed the central barrier back in the tank. A new combination of\nbasslets were placed in the glass containers, and all fish were allowed to\nacclimate for 20 min before removing the barrier and observing predator\nresponse for another 10 min. This procedure was repeated until all 6 basslet\ntreatments had been presented to each predator in random order.

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?
