The Global Invasion of the Suckermouth Armored Catfish Genus Pterygoplichthys (Siluriformes: Loricariidae): Annotated List of Species, Distributional Summary, and Assessment of Impacts.

ABSTRACT: Alexander Benjamin Orfinger and Daniel Douglas Goodding (2018) The suckermouth armored catfish genus Pterygoplichthys (Siluriformes: Loricariidae) includes popular aquarium fishes and constitutes one of the most successful freshwater invasive taxa, having achieved global distribution. To date, however, no comprehensive distributional record nor impact assessment exist for the spread of the genus, precluding informed management strategies. To provide these tools, our study aims to (1) provide an annotated checklist of species for this taxonomically confusing genus, (2) survey all available literature on the spread of the genus and summarize and map its invasive distribution, and (3) assess the overall socioeconomic and environmental impact of the genus on a global scale using the Generic Impact Scoring System (GISS). First, we provide an updated annotated species list. We then summarize seventy-one unique invasion records along with twenty-one instances of demonstrated impacts. Species of the genus Pterygoplichthys have now invaded five continents and twenty-one countries, and show an extended range in their native South America. Impact analysis yielded a GISS score of 18 to 19, indicating low to moderate levels of socioeconomic and environmental threats. However, to bolster the confidence in this analysis in future iterations, more research should aim to move beyond just "first records" and instead empirically evaluate species' effects on native ecosystems.

Project description:Characterizing and naming species becomes more and more challenging due to the increasing difficulty of accurately delineating specific bounderies. In this context, integrative taxonomy aims to delimit taxonomic units by leveraging the complementarity of multiple data sources (geography, morphology, genetics, etc.). However, while the theoretical framework of integrative taxonomy has been explicitly stated, methods for the simultaneous analysis of multiple data sets are poorly developed and in many cases different information sources are still explored successively. Multi-table methods developed in the field of community ecology provide such an intregrative framework. In particular, multiple co-inertia analysis is flexible enough to allow the integration of morphological, distributional, and genetic data in the same analysis. We have applied this powerfull approach to delimit species boundaries in a group of poorly differentiated catfishes belonging to the genus Guyanancistrus from the Guianas region of northeastern South America. Because the species G. brevispinis has been claimed to be a species complex consisting of five species, particular attention was paid to taxon. Separate analyses indicated the presence of eight distinct species of Guyanancistrus, including five new species and one new genus. However, none of the preliminary analyses revealed different lineages within G. brevispinis, and the multi-table analysis revealed three intraspecific lineages. After taxonomic clarifications and description of the new genus, species and subspecies, a reappraisal of the biogeography of Guyanancistrus members was performed. This analysis revealed three distinct dispersals from the Upper reaches of Amazonian tributaries toward coastal rivers of the Eastern Guianas Ecoregion. The central role played by the Maroni River, as gateway from the Amazon basin, was confirmed. The Maroni River was also found to be a center of speciation for Guyanancistrus (with three species and two subspecies), as well as a source of dispersal of G. brevispinis toward the other main basins of the Eastern Guianas.
