Journal ArticleDOI
Is invasion success explained by the enemy release hypothesis
TL;DR: Given the complexity of processes that underlie biological invasions, it is argued against a simple relationship between enemy ‘release’ and the vigour, abundance or impact of NIS.
Journal ArticleDOI
Propagule pressure: a null model for biological invasions
TL;DR: It is concluded that propagule pressure should serve as the basis of a null model for studies of biological invasions when inferring process from patterns of invasion, and ‘propagule biases’ may confound current paradigms in invasion ecology.
Journal ArticleDOI
Dispersal and emerging ecological impacts of Ponto-Caspian species in the Laurentian Great Lakes.
Henry A. Vanderploeg,Thomas F. Nalepa,David J. Jude,Edward L. Mills,Kristen T. Holeck,James R. Liebig,Igor A. Grigorovich,Henn Ojaveer +7 more
TL;DR: Impacts of these benthic invaders vary with site: in some shallow areas, habitat changes and the Dreissena → round goby → piscivore food chain have improved conditions for certain native game fishes and waterfowl; in offshore waters, DreissENA is competing for settling algae with the native amphipod Diporeia spp.
Journal ArticleDOI
Ballast-mediated animal introductions in the Laurentian Great Lakes: retrospective and prospective analyses
Igor A. Grigorovich,Robert I. Colautti,Edward L. Mills,Kristen T. Holeck,Albert G. Ballert,Hugh J. MacIsaac +5 more
TL;DR: In this article, the authors integrated knowledge of species' invasion histories, shipping traffic patterns, and physicochemical factors that constrain species' survivorship during ballast-mediated transfer to assess the risk of future introductions to the Great Lakes.
Journal ArticleDOI
Invasion of Lake Ontario by the Ponto–Caspian predatory cladoceran Cercopagis pengoi
TL;DR: The rapid influx of Ponto-Caspian species into the Great Lakes warrants further study including identification of source populations, mechanisms of dispersal, impacts on recipient ecosystems, and efficacy of ballast water exchange programs.
