attribute | NC_GLOBAL | acquisition_description | String | Area of study and microhabitat assessment\n \nThis study was conducted during July-August 2011, observing the behavioral\nresponse of 40 three spot damselfish:\\u00a020 in the Bahamas and 20 in the\nCayman Islands. Damselfish in these two locations were chosen to be studied\nbecause of their difference in timing of the lionfish invasion: lionfish were\nfirst sighted in the Bahamas in 2004 and in the Cayman Islands in 2008\n(Schofield 2009). In the Bahamas, damselfish were studied at three sites in\nthe shallow waters (sites were <4 m deep) of the Great Bahama Bank in the\nvicinity of Lee Stocking Island, which is part of the Exuma Cays. Study sites\nconsisted of patch reefs composed of small coral heads and larger coral\nbommies surrounded by sand and seagrass beds. About 380 miles Southwest of Lee\nStocking Island, damselfish behavior was observed\\u00a0off of Little Cayman\nIsland at three deeper sites (6\\u201312 m deep) located along the northern\nside of the island, just inshore of the Bloody Bay Wall. This area is\ncharacterized by continuous stretches of reef that includes coral heads of\nvarious sizes and large coral formations.\n \nThe benthic territories maintained year-round by three spot damselfish are\nless than 1 m2 and are easily identified by the algal gardens covering reef\nsubstrata that the damselfish cultivate (Brawley and Adey 1977). The\nunderlying substrata of damselfish territories differed at sites both within\nand between the Bahamas and Cayman Islands. Since the type of habitat could\npotentially affect damselfish response by influencing an individual\\u2019s\nability to defend its territory,\\u00a0the microhabitat of each damselfish\nterritory was characterized by recording the following four habitat\ncategories: (1) low-relief dead coral rubble (mostly Acropora cervicornis),\n(2) low-relief continuous reef, (3) high-relief large coral\\u00a0bommies, and\n(4) high-relief continuous reef. Low-relief habitats lacked vertical\nstructure, whereas\\u00a0high-relief\\u00a0habitats consisted of vertical\nstructure over 1 m high, which could potentially interfere with the ability of\ndamselfish to detect intruders.\n \nExperimental treatments and fish capture\n \nEach three spot damselfish was exposed to a series of treatments consisting of\na single individual of (1) invasive lionfish, or the following native fishes,\nall of which are commonly found on reefs near three spot damselfish\nterritories and are chased at varying degrees by damselfish (Thresher 1976;\nRobertson 1984): (2) herbivorous ocean surgeonfish (Acanthurus bahianus), a\npotential food competitor; (3) white grunt (Haemulon plumierii), a potential\negg predator; and (4) coney grouper (Cephalopholis fulva), a mesopredator\necologically similar to lionfish and at larger sizes is a potential predator\nof three spot damselfish. At both study regions, 2-3 individuals were captured\nper fish species, which were rotated daily for experimental use based on each\nindividual\\u2019s appearance, apparent condition, and behavior. All fish were\ncaught underwater from non-study sites using hand nets and the fish anesthetic\nquinaldine when needed. Body size of individual fish, ranging from 10 to 18 cm\nTL, was restricted to allow for ease of movement in bottles during the\nexperiment. At these sizes, both lionfish and coney grouper were sufficiently\nlarge to pose a threat to small recruit fishes inhabiting damselfish\nterritories (Albins 2013). Fish were maintained in flow-through aquarium tanks\nboth prior to and between daily observational trials.\n \nModel-bottle experiment\n \nUsing a model-bottle study design (Myrberg and Thresher 1974), individual fish\nwere presented in weighted, clear-plastic gallon bottles to haphazardly\nlocated adult damselfish (7\\u201311 cm total length [TL]) in order to measure\nthe relative behavioral responses exhibited by each focal damselfish. Bottle\nlids were replaced with secured mesh screening to allow for flow of both water\nand any fish chemical cues. An empty bottle was used as a control treatment.\nEach treatment was introduced in random order to individual damselfish\nterritories. All fishes inside bottles were either resting or hovering upon\nintroduction.\n \nTo measure damselfish aggression per treatment, each bottle was sequentially\nplaced at 100, 50, and 0 cm away from the center of each territory. At each\nincrement, damselfish behavior was observed from a distance of 3 m for 2 min,\ncounting the number of times the focal damselfish made physical contact with\nthe bottle (attack rate) and tallying which aggressive behaviors each\ndamselfish displayed: (1) contact with the mouth while hovering in place\ndirectly next to the bottle (nip); (2) contact with the caudal fin while\nhovering in place directly next to the bottle (butt); (3) starting from a\ndistance, swimming with force directly towards the bottle, making contact with\nmouth, and then quickly swimming away from the bottle (charge); and, (4)\nrepeatedly charging the bottle multiple times (continuous attack). These\ncategories encompass three spot damselfish behavior known to effectively\nexclude intruders (Thresher 1976). Avoidance behavior by damselfish was also\nnoted, such as entering refuge sites within their territories (Helfman 1989).\n \nEach bottle was then placed at the closest distance to the territory at which\nthe damselfish had previously made no physical contact with the bottle, then\ngradually moved the bottle closer to the center of the territory until the\ndamselfish approached the bottle and made physical contact. If the damselfish\nhad previously attacked the bottle at 100 cm away from the territory, the\nbottle was placed at 150 cm where all damselfish ceased attacking the bottle,\nand gradually moved the bottle closer to the territory from there. This method\nprovided a measurement of the \\u201cmaximum distance of attack\\u201d (sensu\nMyrberg and Thresher 1974) per treatment. |

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? |
