Abstract
One of the major goals of invasion biology is predicting the effects of invaders on native species which is often accomplished by linearly scalingup percapita effects with invader abundance However the relationship between invader density and their ecological impact is poorly understood and it is likely that the effects of invasive species scale nonlinearly with increasing invader density The Pacific red lionfish Pterois volitans is an invasive predator that has reached high abundances throughout the tropical and subtropical western Atlantic Caribbean and Gulf of Mexico A single lionfish can have extremely large effects on native reeffish communities yet the relationship between lionfish density and their ecological effects is not well known I manipulated juvenile lionfish densities on small patch reefs in the Bahamas and monitored the subsequent effects on native coralreef fish abundance biomass richness evenness composite diversity and community structure over 7 weeks Native fish abundance and biomass decreased nonlinearly with increasing lionfish density with the largest drops in abundance and biomass at low lionfish densities and their effects leveling off at high densities Lionfish density also significantly affected richness and community structure but these effects could not be clearly classified as either linear or nonlinear Evenness and composite diversity were not significantly affected by lionfish density Given that the effects of lionfish on native fish abundance and biomass leveloff at high lionfish densities it appears important to remove all lionfish from small patch reefs to have the biggest influence on conserving the native communityThis work was supported by National Science Foundation NSF Grants 0851162 and 1233027 to MA Hixon and an NSF Graduate Research Fellowship to CE Benkwitt This paper is a chapter of my doctoral dissertation Committee MA Hixon advisor SA Heppell SS Heppell L Madsen and BA Menge B Beechler E CernyChipman SL Close ACD Davis E Gorsich SJ Green KI Ingeman AC Iles TL Kindinger TJ Pusack and LJ Tuttle also provided constructive feedback on parts of this manuscript I also thank MA Albins for assistance with R code A Adler for verifying biomass conversions M Crell and S Vojnovich for data entry and ACD Davis TJ Pusack KI Ingeman TL Kindinger LJ Tuttle and the Perry Institute for Marine Science staff and interns for field assistance and support
