Morphology, genetics, and historical records support the synonymy of two ascidian species and suggest their spread throughout areas of the Southern Hemisphere
Abstract:Taxonomic uncertainties and the lack of ecological knowledge can hinder the correct identification and the assignment of biogeographic status of marine species. The ascidian Asterocarpa humilis (Heller, 1878), originally described from New Zealand, has a broad distribution in shallow temperate areas of the Southern Hemisphere, having recently colonised areas of the Northern Hemisphere. A closely related species, Cnemidocarpa robinsoni Hartmeyer, 1916, has been reported in the South-Eastern Pacific and the Sout… Show more
“…I stepped into the picture, eager to leverage my expertise in genetics and molecular markers to advance and deepen our understanding of ascidian biodiversity. We have focused on systematic aspects, identifying species and defining the biogeographic status of cryptogenic species identified in the area (e.g., Alurralde et al, 2018;Taverna et al, 2021). A crucial aspect of our investigation involves tracing the origins of these species, discerning their invasion pathways, the timing of their arrival, and their dispersion patterns.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
