Phylogeographic analysis of the brooding brittle star Amphipholis squamata (Echinodermata) along the coast of New Zealand reveals high cryptic genetic variation and cryptic dispersal potential.

Abstract excerpt

Direct development in benthic marine invertebrates is usually associated with narrow geographical range, low rates of colonization, and low levels of gene flow. Paradoxically, the small brittle star Amphipholis squamata broods its larvae to a crawl-away juvenile stage, yet has a cosmopolitan distribution. Using sequence and restriction-fragment-length-polymorphisms (RFLP) analyses of nuclear and mitochondrial DNA...
