The Dataset's Variables and Attributes

Row Type Variable Name Attribute Name Data Type Value
attribute NC_GLOBAL access_formats String .htmlTable,.csv,.json,.mat,.nc,.tsv
attribute NC_GLOBAL acquisition_description String To determine whether the preference of predators for basslets was driven by
basslet species (fairy and blackcap) or basslet size (small and large:
1.7\u20132.5 and 3.5\u20135.2 cm TL, respectively) we presented pairs of
basslets in cross-factored combinations of the 2 variables, resulting in the
following treatments: (1) small fairy and large fairy, (2) small blackcap and
large blackcap, (3) small fairy and small blackcap, (4) large fairy and large
blackcap, (5) small fairy and large blackcap, and (6) large fairy and small
blackcap. In addition to randomizing the order of basslet treatments presented
to each predator, we also randomized the corner of the tank basslets were
placed in every time a treatment was presented.

Once the predator and basslets were in their respective sides of the tank, we
allowed them to acclimate for 20 min, after which we removed the central
barrier and observed the predator\u2019s behavior for 10 min. Observations
were performed either in person (74 lionfish trials; 73 graysby trials) or
filmed with a digital video camera (16 lionfish trials; 17 graysby trials)
positioned outside of the tank. During each 10 min trial, we recorded (1)
which basslet the predator hunted first (initial hunting preference); (2) the
number of times the predator\u2019s mouth made physical contact with each
glass container (number of strikes); and (3) the amount of time the predator
hunted each basslet (hunting time). We defined the hunting behavior of
lionfish as occurring when an individual directly faced a basslet with flared
pectoral fins and/or blew pulsed jets of water towards a basslet (Cure et al.
2012). We characterized graysby hunting behavior as occurring when an
individual positioned itself near a basslet (<10 cm in this experiment) while
directly facing the basslet (Webster 2004).

At the conclusion of the 10 min trial, we separated the predator from the
basslets and placed the central barrier back in the tank. A new combination of
basslets were placed in the glass containers, and all fish were allowed to
acclimate for 20 min before removing the barrier and observing predator
response for another 10 min. This procedure was repeated until all 6 basslet
treatments 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.
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?
