Abstract: Extinction of tree snails of the genus Partula on Moorea, following
introduction of the predatory snail Euglandina rosea, has challenged conservation
biology during years of successive captive breeding of small rescued populations.
An experimental release of three Partula species into a predator-proof patch
of native forest on Moorea was designed to test effectiveness of physical and
chemical methods of predator exclusion and to evaluate behavior of animals
bred for up to six generations in highly artificial environments. At the close of
the experimental release, there had been multiple incursions of E. rosea, and too
few Partula spp. remained to assess effects of captive breeding on ecological responses.
However, results demonstrated the effectiveness of the exclosure under
ideal maintenance and monitoring. Captive breeding methods were validated by
reproduction and growth to sexual maturity in the wild as well as retention of
genetic variability in the form of persistent color polymorphism in one species.
