attribute NC_GLOBAL acquisition_description String This was a manipulative field experiment conducted during June \\u2013 August\n2013 to determine whether lionfish affect native fishes in the areas\nsurrounding coral patch reefs.\\u00a0 Sixteen patch reefs were paired based on\nsimilarity in location, size, benthic composition, initial fish community, and\nsurrounding habitat, then one reef in each pair was randomly assigned to\neither low-lionfish or high-lionfish treatments.\\u00a0 A pair of divers\nremoved all lionfish from the eight low-lionfish reefs during weekly visits\n(resulting mean lionfish density on low-lionfish reefs was 0.01 to 0.03\nlionfish/square meter).\\u00a0 The eight remaining reefs were maintained as\nhigh-lionfish treatment reefs, with divers adding lionfish to the reefs to\nkeep densities within the naturally occurring range observed in Rock Sound\n(resulting mean lionfish density on high-lionfish reefs was 0.12 to 0.29\nlionfish/square meter. \\u00a0\n \nA pair of divers returned to each reef weekly for 7 weeks to census the native\nfish communities on the main reefs and in three different habitat types in the\nsurrounding areas.\\u00a0 During all surveys, divers counted all fish less than\n15 cm TL and all piscivores of any size.\\u00a0 Around each main reef, selected\nbetween one and four satellite coral heads were haphazardly selected to\nsurvey.\\u00a0 Satellite coral heads were small structures comprised of one to\nseveral coral colonies, ranging in size from 0.31 to 4.7 meters squared and\nlocated between 3.8 and 25.1 m from the main reefs.\\u00a0 In addition to being\nsmaller than the main reefs, satellite heads also supported neither resident\nlionfish nor native piscivores.\\u00a0 To document native fish communities in\nopen sand and seagrass areas without any coral heads or other hard structures,\ntwo 35 m transects were run outward from each main reef in randomly selected\ndirections.\\u00a0 Divers surveyed fish at 5-m intervals within 2 square meter\nplots around the transect tapes.\\u00a0 To obtain a standardized measure of\nfish communities at set distances from each reef that accounted for habitat\ntype, patch size, and initial fish community, I set-up small (0.5 meters\nsquared) identical standardized habitat units (SHUs) consisting of 9 empty\nqueen conch (Strombus gigas) shells with their apertures facing upward.\\u00a0\nAll reefs had one row of 4 SHUs located at 7-m intervals extending away from\nthe reef.\\u00a0 Half of the reefs (4 high-lionfish and 4 low-lionfish reefs)\nalso had a second row of 2 SHUs located at 15 m and 31 m from the reef and\nextending outward in the opposite direction from the first row.\\u00a0 During\nthe final week of the experiment, in addition to visually surveying the fish\ncommunities on the SHUs, a pair of divers placed all conch shells in dry bags\nand brought them up to a boat. Each shell was shaken in a bucket of seawater\nto remove and count any individuals hiding in the shells.\n \nNote that five of the 16 main coral patch reefs had high abundances of small,\njuvenile grunts (Haemulon spp.), which formed large schools of approximately\n100 - 300 individuals above the reefs.\\u00a0 Counts of these juvenile grunts\nare not considered to be precise or accurate. \\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?
