Prehistoric aesthetics explains snail biogeography puzzle
| Quote: | ANN ARBOR, Mich.—The answer to a mystery that long has puzzled biologists may lie in prehistoric Polynesians' penchant for pretty white shells, a research team headed by University of Michigan mollusk expert Diarmaid Ó Foighil has found.
The team's findings, published online Sept. 12 in the British biological research journal Proceedings of the Royal Society B, have implications for conservation efforts aimed at rescuing nearly-extinct Tahitian tree snails.
The study focused on a tree snail species, Partula hyalina, found on the island of Tahiti—where it has been nearly wiped out by a predatory snail introduced in the 1970s—and also on the Austral and Southern Cook Islands. The snail's multiarchipelago distribution is unique in the partulid tree snail family; most are restricted to single islands. |
