| cryptic species and morphological plasticity in long-lived bivalves (unionoida: hyriidae) from inland australia. | molecular (mitochondrial dna, isozyme) and morphological diversity of freshwater mussels (family hyriidae) was examined at 21 sites encompassing four large river systems, across southwest queensland, australia. evidence was found for two major morphological groups. one group, which occurred in every river system, closely matched a recognized species (velesunio ambiguus) both morphologically and in a well-supported lineage within a mitochondrial phylogeny generated from partial cytochrome c oxida ... | 2003 | 12969474 |
