AUTHORS: Kensey Thurner*, Purdue University

ABSTRACT: Accidental and intentional movement of species around the world by humans has created unprecedented colonization opportunities for non-native, aquatic species. At the same time, it is often not economically or physically possible to prevent introductions or remove established aquatic invaders. These introductions have, however, sometimes led to severe impacts on receiving ecosystems, including extirpations of native species, alterations of habitat and loss of economic value. While much focus has been paid to invasive vertebrates and commercially valuable species, the impacts from aquatic invasive pathogens (AIP) can be equally significant. I conducted this review of aquatic invasive pathogens in North America to aid resource managers who must prioritize highly impactful invasive species when allocating limited resources for monitoring and control efforts. A review of the literature and invasive species databases revealed inconsistencies in the up-to-dateness of these databases and a paucity of information on invasive pathogens in aquatic environments. AIP were rarely included in databases or were not updated despite their potential for substantial impacts. Furthermore, data relating to invasive species in Mexico was scarce in comparison to the USA and Canada, leading to the appearance of far fewer invasive species in Mexico. Additionally, AIP in the literature showed a strong bias toward agriculturally important and charismatic species. Meanwhile, advances in next-generation sequencing and eDNA-related technologies provide opportunities to better characterize these understudied and potentially harmful group of invaders.
