    Notes: Abstract The development of ex situ conservation work for Orthoptera is demonstrated by examples of two captive-breeding programmes at the Zoological Society of London. The field cricket Gryllus campestris and wart-biter bush cricket Decticus verrucivorus are both species that have been bred in captivity and reintroduced to field sites in attempts to strengthen dwindling wild populations. Despite a similar approach to both programmes, we have encountered significant differences in the practical applications of the captive management process for the two species. By reviewing these breeding programmes, we examine some of the practical considerations associated with ex situ orthopteran programmes and compare some of the different elements that can influence programme success.

    Notes: Abstract A population of zoo bred Partula taeniata was released into a patch of native Polynesian plants in the Palm House at the Royal Botanic Gardens, Kew, London, UK. The released snails were from a colony established from wild-caught snails in 1982, which had been in captive conditions for up to six generations. Monitoring of the snails was continuous and intensive for the first 2 weeks, and at decreasing frequency over the next 15 months. There was high survivorship early on in the release, but once the intensive monitoring ended survivorship became hard to determine due to difficulties in locating snails in the large and complex habitat. However, snails are known to have persisted for at least 15 months, and new individuals have been noted maturing into all developmental stages. The snails exhibited patterns of feeding and microhabitat choice similar to those observed in the wild, despite being reared in a highly artificial environment. The methods and results provide some guidelines for future release trials for this highly endangered group of snails.
