The impacts of the invasive lionfish on Caribbean food webs

A high-resolution model of a Greater Antilles coral reef food web, including micro- and macrobiota, suppliers and consumers, as well as invertebrates and vertebrates, was used to investigate P. volitans' community structural parameters, including food chain length, number of interactions, modularity, and trophic position. As the prey of the lionfish was found to be functionally indiscriminate relative to those of extirpated predators such as Sphyrna tiburo, Carcharhinus acronotus, and Galeocerdo cuvier, a tiburo is presumed to be functionally indiscriminate relative to those of extirpated predators such as Sphyrna ti In addition, food web findings show that lionfish change the overall reef community's trophic balance by increasing the total number of interactions and changing trophic level structure. Interestingly, the invasive lionfish can be recovering and augmenting some effects of predation that were otherwise unirpated, providing an alternative viewpoint on Caribbean marine ecosystems' resilience.
