Dataset Description: <p>This dataset contains results from a field experiment to test for the effect of lionfish and native fish presence on settlement of coral-reef fishes. Native and invasive predators were placed in cages next to small artificial reefs and new recruits settling to reefs were counted and removed daily. Treatments were also rotated daily.&nbsp; Two rounds of the experiment were run, bracketing the new moon (when settlement rates are highest) in July and August 2014.&nbsp;Sampling took place off the leeward coast of Bonaire, Dutch Caribbean (12°09'13.0"N 68°16'42.8"W) at a 5-meter depth.</p>
<p>These data were utilized in the following publication (Benkwitt 2017)<br /> Methods and Sampling: <p>Two manipulative field experiments were conducted July-August 2014, both using the same basic experimental design. Standardized reefs (80 × 60 × 15 cm) were constructed using dead coral rubble placed inside of stainless steel wire baskets. Predators were housed next to reefs in individual hardware-cloth cages (150 mm diameter × 300 mm length, 10 mm mesh) such that recruiting coral-reef fish were exposed to chemical and some visual cues from the predator, but the predator could not consume recruits. To measure settlement, a pair of divers counted and removed all fish from each reef every morning beginning within an hour of sunrise. In the first experiment, each reef within each of block was randomly assigned one of the following treatments: invasive piscivore (red lionfish), native piscivore (graysby grouper), native invertivore (French grunt), empty cage (no predator), and empty control (no cage and no predator). To determine whether the diet of native or invasive predators affects settlement, the experiment described above was repeated using different treatments. Each reef within each block was randomly assigned one of the following treatments: native piscivore (graysby grouper) fed bicolor damselfish recruits, native piscivore (graysby grouper) fed mahogany snapper recruits, invasive piscivore (red lionfish) fed bicolor damselfish recruits, invasive piscivore (red lionfish) fed mahogany snapper recruits, and empty cage control. Recruits of these two reef fishes were chosen as feed for the predators because they were the most abundant recruits to the reefs during the first experiment. For full methods, see Benkwitt (2017).&nbsp;</p>
<p>Reef configuration:<br />
The reefs referred to in this dataset are 80 × 60 × 15 cm patches of coral rubble inside of stainless steel baskets.&nbsp; These were arranged in groups/blocks (letter codes B-E) that were separated from the next block by~17 m.&nbsp; Each block contained five reefs (numbered 1-5), which were separated from each other by ~3 m.&nbsp; The latitude and longitude&nbsp;(12.15361,-68.27855)&nbsp;corresponds to the approximate the center of the array.&nbsp;</p>

Mechanisms and Consequences of Fish Biodiversity Loss on Atlantic Coral Reefs Caused by Invasive Pacific Lionfish

Mechanisms and Consequences of Fish Biodiversity Loss on Atlantic Coral Reefs Caused by Invasive Pacific Lionfish
<p>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.</p>
<p>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? </p>
