The Invasive Lionfish
Author: Harris A. SullivanPublisher: Nova Science Publishers
ISBN: 9781629481159
Category : Science
Languages : en
Pages : 161
Book Description
Venomous Indo-Pacific lionfish (Pterois miles and P. volitans) are now established along the Southeast U.S.A. and parts of the Caribbean and pose a serious threat to reef fish communities of these regions. Lionfish are likely to invade the Gulf of Mexico and potentially South America in the near future. Introductions of lionfish were noted since the 1980s along south Florida and by 2000 lionfish were established off the coast of North Carolina. Lionfish are now one of the more numerous predatory reef fishes at some locations off the Southeast U.S.A. and Caribbean. Lionfish are largely piscivores that feed occasionally on economically important reef fishes. The trophic impacts of lionfish could alter the structure of native reef fish communities and potentially hamper stock rebuilding efforts of the Snapper -Grouper Complex. Additional effects of the lionfish invasion are far-reaching and could increase coral reef ecosystem stress, threaten human health, and ultimately impact the marine aquarium industry. Control strategies for lionfish are needed to mitigate impacts, especially in protected areas. This book provides a general overview of the biology and ecology of lionfish including genetics, taxonomy, reproductive biology, early life history and dispersal, venom defense and predation, and feeding ecology. In addition, alternative management actions for mitigating the negative impacts of lionfish, approaches for reducing the risk of future invasions, and directions for future research are provided.

Mesophotic Coral Ecosystems
Author: Yossi LoyaPublisher: Springer
ISBN: 3319927353
Category : Science
Languages : en
Pages : 984
Book Description
This book summarizes what is known about mesophotic coral ecosystems (MCEs) geographically and by major taxa. MCEs are characterized by light-dependent corals and associated communities typically found at depths ranging from 30-40 m. and extending to over 150 m. in tropical and subtropical ecosystems. They are populated with organisms typically associated with shallow coral reefs, such as macroalgae, corals, sponges, and fishes, as well as specialist species unique to mesophotic depths. During the past decade, there has been an increasing scientific and management interest in MCEs expressed by the exponential increase in the number of publications studying this unique environment. Despite their close proximity to well-studied shallow reefs, and the growing evidence of their importance, our scientific knowledge of MCEs is still in its early stages. The topics covered in the book include: regional variation in MCEs; similarities and differences between mesophotic and shallow reef taxa, biotic and abiotic conditions, biodiversity, ecology, geomorphology, and geology; potential connectivity between MCEs and shallow reefs; MCE disturbances, conservation, and management challenges; and new technologies, key research questions/knowledge gaps, priorities, and future directions in MCE research.

Invasive Pacific Lionfish Alters Native Community Interactions on Atlantic Coral Reefs

Book Description
Biological invasions have been identified as one of the prominent drivers of global environmental change. In particular, invasive predators typically have substantial negative effects on populations of native prey, even driving species to extinction in extreme cases. However, beyond direct predatory effects, little is understood regarding the specific mechanisms by which invasive predators influence native communities and ecosystems. Therefore, the objective of this dissertation was to investigate whether and how an invasive predator, the Pacific red lionfish (Pterois volitans), alters native community interactions on Atlantic coral reefs. The lionfish invasion is unprecedented for a marine fish in the extent of rapid geographical spread, successful establishment across numerous habitats, and strong predatory effects on native species. By conducting behavioral observations and manipulative experiments in both the laboratory and field settings, I tested for a variety of direct and indirect mechanisms by which invasive lionfish potentially influence native fish communities and coral-reef ecosystems. I first conducted a model-bottle experiment in The Bahamas and Cayman Islands (Chapter 2) to test for aggression of a native territorial damselfish, Stegastes planifrons, toward invasive lionfish. Such territoriality could provide a possible source of biotic resistance that may provide behavioral refugia for native coral-reef fish recruits from lionfish predation. However, the behavior of this damselfish in response to invasive lionfish in a clear plastic bottle did not differ from the minimal response exhibited toward the empty bottle control. Therefore, the territories of this damselfish are unlikely to provide such biotic resistance to the invasion. To investigate whether invasive lionfish alter competition between native prey fishes, I then performed a manipulative field experiment in The Bahamas whereby I simultaneously tested for the effects of both competition and lionfish predation on two congeneric coral-reef fishes, the fairy and blackcap basslets (Gramma loreto and G. melacara, respectively). In the absence of invasive lionfish, competition within local populations of basslets under reef ledges had symmetrical effects on the juveniles of both species (Chapter 3). Interference between species drove juvenile basslets further back under ledges where feeding and growth rates of individuals were reduced. Within reefs with the invasive predator present (Chapter 4), lionfish reduced the density of juvenile fairy basslet, thereby reducing the effects of competition on juvenile blackcap basslet, and tipping the balance of competition between juveniles of these species from symmetrical to asymmetrical effects. Differential predation of invasive lionfish may be explained by a preference for fairy basslet, as demonstrated by a laboratory experiment (Chapter 5). Lastly, I examined possible mechanisms underlying a potential invasive lionfish-herbivorous fishes-macroalgae trophic cascade on large reefs in The Bahamas (Chapter 6). During a two-year field experiment, lionfish caused a decline in the density of small herbivorous fishes on reefs, and behavioral observations revealed that the presence of lionfish reduced grazing by both small and large fishes, which resulted in 66-80% less algae removed from reef substrata. Therefore, invasive lionfish have both consumptive and non-consumptive effects on the important ecosystem function of native herbivorous fishes: reducing the abundance of benthic algae that could otherwise displace corals. In sum, this dissertation indicates that throughout native coral reefs, invasive lionfish (1) are not attacked by native territorial damselfish that could otherwise provide local refugia for native recruit fishes; (2) alter the outcome of interspecific competition between native basslets via differential predation that tips the balance of competition from symmetrical to asymmetrical; and (3) have both consumptive and non-consumptive effects on native herbivorous fishes, which reduces grazing and indirectly benefits benthic macroalgae to the possible detriment of corals. This research broadens our mechanistic understanding of predation in the context of invasive species, which further informs predictions relevant for management and conservation initiatives.
