摘要

采用实验室饲养的10只马地兰地方性地蜗牛成年标本,饲养一窝110个卵,对1240天的幼虫死亡率、生长和繁殖能力进行了监测。在70只幼龟中,有34只存活到640天左右,完成了外壳的生长。生长迅速,早期死亡率高;生长缓慢,死亡率非常低,因为它接近全尺寸。单独饲养的蜗牛不能下蛋。在那些有潜在配偶的幼崽中,只产下了三窝,其中一窝没有孵化。卵壳生长完成至少五个月后才会产生卵壳。性成熟后死亡率急剧上升,最老的蜗牛能存活三年半。讨论了明显非常严格的半产繁殖方式,延迟性成熟和相对较长的幼鱼生长期与其他物种的关系,以及饲养潜在濒危物种的实际问题。

Selected life history traits of Leptaxis simia (Gastropoda: Hygromiidae) established in the laboratory
Among ten adult specimens of the Madeiran endemic land snail Leptaxis simia kept in the laboratory, a single clutch of 110 eggs was reared, and the mortality, growth and reproductive capacity of hatchlings over a 1240- day period were monitored. Of 70 hatchlings, 34 survived to complete shell growth at around 640 days. Growth was rapid, and mortality high in the early stages; growth slowed and mortality was very low as full size was approached. Snails kept singly failed to lay any eggs. Among those with potential mates, only three clutches were produced, one of which yielded no hatchlings. Clutches were produced at least five months after shell growth was complete. Mortality increased sharply after the onset of sexual maturity, and the oldest snail survived for three and a half years. The apparently very strictly semelparous mode of reproduction, delayed sexual maturity and relatively long period of juvenile growth are discussed in relation to other species, and to the practical problems of rearing potentially endangered species in captivity.

期刊介绍: Acta Zoologica Academiae Scientiarum Hungaricae publishes original works in the fields of animal taxonomy and systematics, zoogeography, animal ecology and behaviour, population biology, biodiversity studies and nature conservation problems of international interest. Short communications, check lists, catalogues or new species records for a given region are not in focus of the scope of the journal.
