Book excerpt: Predatory lionfishes (Pterois volitans and P. miles) were introduced to Florida waters during the mid to late 1980s, and eventually established self-sustaining breeding populations in the tropical western Atlantic. These invasive species are now widespread along the southeastern seaboard of the United States, across the Caribbean Sea, and in the Gulf of Mexico. In these regions, lionfish reach larger maximum sizes and higher abundances than they do in their native Pacific, suggesting that they have undergone ecological release. Invaded marine communities have thus far provided little if any biotic resistance. Lionfish are generalist predators with high consumption rates, inhabit a broad range of habitats, are defended from predation by venomous spines, and are capable of long-range larval dispersal. It is possible that lionfish have direct effects on native communities, through consumption of native fishes and competition with native predators, as well as indirect effects, such as overconsumption of herbivorous fishes that prevent seaweeds from outcompeting reef-building corals. There is also serious concern that invasive lionfish could act additively, or even synergistically, with existing stressors of coral-reef systems, such as overfishing and ocean warming, resulting in substantial negative consequences for native ecosystems and economically valuable fisheries. The primary goal of this dissertation was to conduct a set of controlled, replicated field experiments to rigorously examine and measure the effects of lionfish on native reef-fish communities across a range of spatial and temporal scales. In the first experiment (Chapter 2), the net recruitment of native fishes to twenty small patch reefs was compared in the presence (n = 10) and absence (n = 10) of lionfish. This study demonstrated that lionfish reduced net recruitment, or change in abundance of small native fishes, by an average (± SEM) of 78.9 ± 32.2 % over 5 weeks, affecting 23 of 38 species recruiting to reefs in both treatments. In a second experiment (Chapter 4), I examined the effects of lionfish on patch-reef communities of small native fishes relative to, and in combination with, those of a similarly sized native predator, the coney grouper (Cephalopholis fulva). Four different predator treatments were established by transplanting predators (n = 5 reefs each). Treatments included a single small invasive lionfish, a single small native grouper, a grouper and a lionfish together, and predator-free controls. Compared to controls, invasive lionfish caused reductions (mean ± SEM) in abundance (93.7 ± 17.8 %) and species richness (4.6 ± 1.6 species) of small native fishes. The negative effect of lionfish on abundance was 2.6 ± 0.5 times stronger than that of the native grouper. The greatest negative effects on abundance, species richness, evenness, and diversity of native fishes occurred when both lionfish and native grouper were present. Additionally, lionfish grew more than six times faster in both length and mass than did native grouper. A third experiment (Chapter 6) assessed the effects of lionfish on native reef-fish communities at spatial and temporal scales directly relevant to management and conservation efforts. Subsequent to baseline surveys, high- and low-density lionfish treatments were established on 10 large (1400 to 4000 m2) isolated coral reefs. After initiation of treatments, quarterly surveys of the native reef-fish communities were conducted for approximately 14 months. Lionfish caused significant reductions (mean ± SEM) in density (up to 3.22 ± 0.95 fish m−2), biomass (3.26 ± 1.10 g m−2), and species richness (4.92 ± 2.09 species) of small (

Book excerpt: 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.

This book was released on 2016 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: What makes invasive species successful, and how do they affect native populations and communities? I addressed these key questions in the context of the invasion of Atlantic coral reefs by Pacific red lionfish (Pterois volitans). To assess the role of parasites in contributing to the success of this invasion, I compared infection rates of lionfish with syntopic carnivorous fishes at multiple locations in both the invasive and native ranges of lionfish. Invasive Atlantic lionfish had extremely few parasites when compared both to native Pacific lionfish and to ecologically similar native Atlantic reef fishes. Such “enemy release” may help to explain this successful invasion if lionfish consequently allocate more energy to growth and reproduction than to costly immune defenses. With few parasites limiting them, lionfish may consume ecologically important species, including Elacatinus spp. cleaning gobies: ubiquitous, conspicuous fishes that remove ectoparasites from other reef fishes. Although juvenile lionfish ate cleaner goby (E. genie) during laboratory experiments, they quickly learned to avoid them, likely due to a previously undescribed skin toxin in these gobies. Field experiments further revealed no change in the survival and growth rates of newly recruited cohorts of the cleaner goby in the presence vs. absence of lionfish. However, lionfish caused declines in the densities of the most abundant facultative cleaner, juvenile bluehead wrasse (Thalassoma bifasciatum), and of transient fishes that are often cleaned while visiting coral patch reefs. Therefore, lionfish do not have uniformly negative effects on native species; distasteful to potential predators, the cleaner goby is among the remarkably few small fish to escape predation by lionfish. The continued presence of Elacatinus spp. cleaning gobies, the predominant cleaners on invaded reefs, should limit cascading effects of lionfish on other Atlantic coral-reef inhabitants. Nonetheless, given their broad and voracious appetites, invasive lionfish will likely continue to affect native reef communities via predation on other cleaners and ecologically important fishes.

Available in PDF, EPUB and Kindle. Book excerpt: 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 defence 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.

Book excerpt: Invasive species cause significant ecological impacts, ranging from the homogenization and reduction of biodiversity to changes in ecosystem function. In marine systems, where predation is a key force shaping demographic processes, predatory invaders are predicted to have particularly severe effects. My thesis focuses on the patterns, processes and consequences of the recent invasion of Western Atlantic coral reef habitats by predatory Indo-Pacific lionfish (Pterois volitans and P. miles). I first investigate the rate and timing of predation by lionfish through in situ observations on invaded Bahamian coral reefs, and find that lionfish primarily consume prey during crepuscular periods and at higher rates than reported from their native range. Next, I examine trends in the biomass of 42 native fishes found in the stomach contents of lionfish on invaded reefs, and find declines of ~65% in just two years likely owing to lionfish predation. Through field observations of predation and stomach contents analyses, I identify morphological and behavioural drivers of prey selection by lionfish: small size, shallow body depth, demersal habit, and not cleaning all contribute vulnerability to predation. Using these insights, I model the effect of lionfish predation on the biomass of their fish prey, taken as the difference between rates of lionfish prey consumption and prey fish production on invaded reefs, the latter estimated from community size-spectra data using metabolic scaling relationships. My model accurately predicts the magnitude of prey depletion observed on Bahamian reefs, and reveals that lionfish are likely to continue depleting native fishes unless culled by 30-95%. Finally, I conduct a removal experiment on 24 natural patch reefs over 18 months to test the model's predictions, and find that the lionfish density reductions predicted by the model are sufficient arrest native fish biomass declines. My thesis reveals the important role that invasive lionfish now play in structuring Atlantic coral reef fish communities, and quantifies the threat of invasion for the persistence of fish diversity in the region. However, by demonstrating that lionfish removal can limit the severe ecological impacts of this invasive predator, my research offers strategic targets and much needed hope for local marine management action.

This book was released on 2016 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although only a minority of introduced species become established and have noticeable consequences in their new communities, some can displace native species, alter food webs, and cause local extinctions. Studying these invasive species can provide new insights into basic ecological questions as well as inform management strategies. Pacific lionfish (Pterois volitans/miles) are the first non-native marine fish to become established throughout the tropical and sub-tropical western Atlantic. Since the early 2000s, lionfish populations have spread rapidly and grown exponentially, reaching densities that are several orders of magnitude greater than those in their native range. Combined with these high population sizes, lionfish have strong negative effects on native coral-reef fish populations via direct predation. The main goals of this dissertation were to determine how the local density of lionfish influences their demographic rates and behavior, and in turn, how lionfish affect native fish populations at different lionfish densities, across multiple habitats, and via non-consumptive effects. In the first experiment, I manipulated densities of juvenile lionfish on ten small artificial patch reefs The Bahamas and for 8 weeks monitored their demographic rates (Chapter 2) and effects on native-fish communities (Chapter 4). Although there was no evidence for density-dependent per capita rates of loss (mortality and emigration) or gain (recruitment and immigration), individual growth rates decreased at higher densities. For each increase in lionfish density by 1 fish/m2, lionfish grew an estimated 0.02 mm/day slower. In addition, native fish abundance and biomass declined non-linearly with increasing lionfish density, such that lionfish had diminishing per-capita effects on native fishes at higher densities. Observations of lionfish conducted on sixteen coral patch reefs encompassing a natural range of lionfish densities revealed that lionfish foraging behavior and movements also vary with local lionfish density (Chapter 3). At higher densities, lionfish exhibited greater activity levels and increased time away from shelter, including more short-term foraging movements between coral patch reefs and surrounding seagrass habitats. Combined, these patterns suggest that invasive lionfish experience intraspecific competition for food. The foraging movements of lionfish may also have implications for which native species are susceptible to lionfish predation. By manipulating sixteen patch reefs in The Bahamas to have either high or low lionfish densities and comparing changes in native fish populations on and around the reefs for 7 weeks, I determined that lionfish first caused an approximately 60% reduction in the abundance of native fishes on the patch reefs and then caused similar declines on small structures in seagrass beds that surround these reefs (Chapter 5). Unlike the effects of native predators on prey fishes, the effects of lionfish did not diminish rapidly with increasing distance from coral patch reefs, likely because lionfish have few natural predators and thus may forage with impunity over extended distances. The negative effects of lionfish predation both on and around coral reefs are likely compounded by the fact that some prey fishes are naïve to the threat posed by lionfish. During a critical life-history transition from pelagic larvae to reef-associated juvenile (‘settlement’, measured as ‘recruitment’), some coral-reef fishes recognize cues from predators and consequently preferentially settle to reefs without predators. To test whether lionfish have similar non-consumptive effects on the recruitment of coral-reef fishes, I manipulated the presence, identity, and diet of prior resident fishes and measured daily recruitment to fifteen small standardized reefs in Bonaire (Chapter 6). Regardless of predator diet, one species of reef fish had 55-59% lower recruitment to reefs with a native predator compared to predator-free control reefs and reefs with lionfish, suggesting that they recognize and avoids cues from native predators but not invasive lionfish. Overall, this research clarifies the extent and mechanisms underlying the ecological effects of invasive lionfish. In terms of management, the lack of density- dependent gain and loss rates suggest that current efforts to reduce local densities via manual removal by divers are likely to remain the most effective management strategy for the foreseeable future. Due to the non-linear effects of lionfish on native fish populations on coral patch reefs and their effects in surrounding areas, management efforts that greatly reduce lionfish densities on coral patch reefs will have the greatest benefit for native fishes across multiple habitats. Finally, because at least one species of reef fish has lower recruitment to reefs with native predators compared to lionfish, monitoring strategies that simply compare the abundance of native fishes on reefs with lionfish to reefs with native predators will likely underestimate the consumptive effects of lionfish. This research also reveals that invasive lionfish are different than native coral-reef mesopredators in many ways: they do not experience density-dependent population gain and loss rates at current high densities, they forage over broad distances encompassing multiple habitats, and they are unrecognizable to at least some native prey fishes. In addition, typical anti-predator strategies of small native fishes, including inhabiting seagrass beds instead of coral patch reefs and avoiding reefs with predators at settlement, are ineffective against lionfish. These characteristics likely at least partially explain why lionfish have such strong negative effects on native coral-reef fishes, and some of these traits are likely shared by other successful invasive predators.

Available in PDF, EPUB and Kindle. Book excerpt: How does behaviour affect biological invasions? Can it explain why some animals are such successful invaders? With contributions from experts in the field, and covering a broad range of animals, this book examines the role of behaviour in biological invasions from the point of view of both invaders and native species. The chapters cover theoretical aspects, particularly relevant behaviours and well-documented case studies, showing that behaviour is critical to the success, and ecological and socio-economic impact, of invasive species. Its insights suggest methods to prevent and mitigate those impacts, and offer unique opportunities to understand the adaptive role of behaviour. Offering a comprehensive overview of current understanding on the subject, the book is intended for biological invasion researchers and behavioural ecologists, as well as ecologists and evolutionary biologists interested in how organisms deal with anthropogenic environmental changes such as climate change and habitat loss.

Book excerpt: 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.
