Trait-based vulnerability reveals hotspots of potential impact for a global marine invader.

Glob Chang Biol 2021 Jun 5. Epub 2021 Jun 5.

Biological Sciences, University of Alberta, Edmonton, Canada.

Predation from the invasive Indo-Pacific lionfish is likely to amplify declines in marine fishes observed in multiple ocean basins. As the invasion intensifies and expands, there is an urgent need to identify species that are most at risk for extirpation - and possible extinction - from this added threat. To address this gap and inform conservation plans, we develop and apply a quantitative framework for classifying the relative vulnerability of fishes based on morphological and behavioural traits known to influence susceptibility to lionfish predation (e.

Predator-Prey Interactions Examined Using Lionfish Spine Puncture Performance.

Integr Org Biol 2021 27;3(1):obaa049. Epub 2021 Jan 27.

Biological Sciences, Florida Atlantic University, 777 Glades Road, Boca Raton, FL 33431, USA.

Puncture mechanics can be studied in the context of predator-prey interactions and provide bioinspiration for puncture tools and puncture-resistant materials. Lionfish have a passive puncture system where venomous spines (dorsal, anal, and pelvic), the tool, may embed into a predator's skin, the target material, during an encounter. To examine predator-prey interactions, we quantified the puncture performance of red lionfish, , spines in buccal skin from two potential predators and porcine skin, a biological model for human skin.

Lionfish envenomation in Caribbean and Atlantic waters: Climate change and invasive species.

Int J Womens Dermatol 2021 Jan 4;7(1):120-123. Epub 2020 Jul 4.

The George Washington School of Medicine & Health Sciences, Washington, DC, United States.

The concept of emerging diseases is well understood; however, the concept of emerging injuries is not. We describe the introduction of two species of lionfish, native to the Indian and Pacific Oceans, into the warm shallow coastal waters of the Western Atlantic Ocean and the Caribbean Sea. Lionfish thrive in the same coastal waters that attract recreational swimmers, snorkelers, and divers. Read More

Early life ecology of the invasive lionfish (Pterois spp.) in the western Atlantic.

PLoS One 2020 10;15(12):e0243138. Epub 2020 Dec 10.

Southeast Fisheries Science Center, NOAA National Marine Fisheries Service, Miami, Florida, United States of America.

The invasion of the western Atlantic by the Indo-Pacific lionfish (Pterois volitans/miles) is a serious threat to the ecological stability of the region. The early life history of the lionfish remains poorly understood despite the important role that larval supply plays reef fish population dynamics. In this study, we characterized patterns in the horizontal and vertical distributions of larval lionfish collected in the western Caribbean, US Caribbean, and the Gulf of Mexico from 19 ichthyoplankton surveys conducted from 2009-2016.

Testing the efficacy of lionfish traps in the northern Gulf of Mexico.

PLoS One 2020 26;15(8):e0230985. Epub 2020 Aug 26.

Department of Fisheries and Aquatic Sciences, School of Forest Resources and Conservation, Institute of Food and Agriculture Sciences, University of Florida, Gainesville, Florida, United States of America.

Spearfishing is currently the primary approach for removing invasive lionfish (Pterois volitans/miles) to mitigate their impacts on western Atlantic marine ecosystems, but a substantial portion of lionfish spawning biomass is beyond the depth limits of SCUBA divers. Innovative technologies may offer a means to target deepwater populations and allow for the development of a lionfish trap fishery, but the removal efficiency and potential environmental impacts of lionfish traps have not been evaluated. We tested a collapsible, non-containment trap (the 'Gittings trap') near artificial reefs in the northern Gulf of Mexico. Read More

Dermal modifications of the red lionfish, Pterois volitans.

J Exp Zool A Ecol Integr Physiol 2020 11 29;333(9):637-643. Epub 2020 Jul 29.

Department of Biological Sciences, Florida Atlantic University, Boca Raton, Florida.

Vertebrates have evolved flexible and hard dermal armor, but there is often a tradeoff between mobility and protection. Skeletal modifications include fish scales, the shells of tortoises and turtles, and the cranial projections that are found in marine iguanas and lionfish. Sexual dimorphisms of cranial structures are prominent in fishes; we hypothesized that cranial projections of Pterois volitans will change over ontogeny and are sexually dimorphic. Read More

Lionfish (Pterois volitans) as biomonitoring species for oil pollution effects in coral reef ecosystems.

Mar Environ Res 2020 Apr 8;156:104915. Epub 2020 Feb 8.

NOAA, National Ocean Service, National Centers for Coastal Ocean Science, Charleston, SC, USA.

With oil spills, and other sources of aromatic hydrocarbons, being a continuous threat to coral reef systems, and most reef fish species being protected or difficult to collect, the use of the invasive lionfish (Pterois volitans) might be a good model species to monitor biomarkers in potentially exposed fish in the Caribbean and western Atlantic. The rapid expansion of lionfish in the Caribbean and western Atlantic, and the unregulated fishing for this species, would make the lionfish a suitable candidate as biomonitoring species for oil pollution effects. However, to date little has been published about the responses of lionfish to environmental pollutants. Read More

Differential Bioaccumulation of Trace Elements and Rare Earth Elements in the Muscle, Kidneys, and Liver of the Invasive Indo-Pacific Lionfish (Pterois spp.) from Cuba.

Biol Trace Elem Res 2020 Jul 18;196(1):262-271. Epub 2019 Nov 18.

Chemistry Department, Environmental Contaminants Laboratory, Istituto Zooprofilattico Sperimentale del Piemonte, Liguria e Valle d'Aosta, via Bologna 148, 10154, Turin, Italy.

The Indo-Pacific lionfish is a saltwater fish that inhabits the Red Sea waters and the Indian and Pacific oceans; it is an invasive species in the western Atlantic and was recently introduced into the local diet in the USA, Central and South America, and the Caribbean with the aim of controlling the invasion of this species. Due to its predatory nature, it tends to bioaccumulate metals and other contaminants via the marine food web and could thus constitute a suitable species for monitoring aquatic ecosystems. The presence and distribution of 23 trace elements and 16 rare earth elements (REEs) were investigated by inductively coupled plasma-mass spectrometry (ICP-MS) in the muscle, liver, and kidneys of lionfish from Cuba.

Genetic structure of Mexican lionfish populations in the southwest Gulf of Mexico and the Caribbean Sea.

PLoS One 2019 1;14(10):e0222997. Epub 2019 Oct 1.

Consejo Nacional de Ciencia y Tecnología / Universidad de Quintana Roo, Chetumal, Quintana Roo, Mexico.

The recent expansion of the invasive lionfish throughout the Western Hemisphere is one of the most extensively studied aquatic invasions. Molecular studies have improved our understanding of larval dispersal, connectivity, and biogeographical barriers among lionfish populations, but none have included Mexican localities, an important area for the larval dispersal of Pterois volitans through the Western Caribbean and the Gulf of Mexico. Here, we present a genetic analysis of lionfishes collected along Mexican coasts, examining their connectivity with other Caribbean localities (Belize, Cuba, Puerto Rico) and the role of ocean currents on population structure.

From individual movement behaviour to landscape-scale invasion dynamics and management: a case study of lionfish metapopulations.

Philos Trans R Soc Lond B Biol Sci 2019 09 29;374(1781):20180057. Epub 2019 Jul 29.

Department of Biological Sciences, Simon Fraser University, 8888 University Drive, Burnaby, British Columbia, Canada V5A 1S6.

Modelling the dynamics of small, interconnected populations, or metapopulations, can help pinpoint habitat patches that are critical for population persistence in patchy habitats. For conservation purposes, these patches are typically earmarked for protection, but for invasive species management, these patches could be targeted to hasten the populations' demise. Here, we show how metapopulation modelling, coupled with an understanding of size-dependent dispersal behaviour, can be used to help optimize the distribution of limited resources for culling specific populations of invasive Indo-Pacific lionfish (Pterois volitans) in the western Atlantic.
