| Invasion of the Clonal Clams: Corbicula in the New World Diarmaid Ó Foighil1, Taehwan Lee1, Sirirat Siripattrawan & Cristián F. Ituarte2 1Museum of Zoology, University of Michigan, Ann Arbor, MI 48109, USA, diarmaid@umich.edu; 2Museo de La Plata, 1900 La Plata, Buenos Aires, Argentina | |||
Unknown In the New World prior to 1924, the exotic bivalve Corbicula now ranges from Michigan to Patagonia and is one of the most common freshwater mollusks in the Americas. Michigan populations are composed of a triploid lineage which shares a distinct shell morphotype, mitochondrial (mt) haplotype and nuclear ribosomal genotype with New World populations spanning a remarkable 85° of latitude and incorporating temperate, subtropical and tropical watersheds. Two additional mt and nuclear ribosomal Corbicula lineages were detected in a minority of New World populations and all three exotics produce biflagellate sperm, a morphological marker for clonality in this clam taxon. Corbicula is but one of hundreds of recent New World freshwater exotics and its extraordinarily rapid bicontinental spread may well be a portent of things to come. We anticipate that over the next decades, many other New World freshwater exotics will gradually attain extensive bicontinental distributions. | |||
