资源简介:
The moth genus Hyposmocoma is a highly diverse group of micro-lepidopterans endemic to the Hawaiian islands. With more than 300 described species and more than 600 thought to exist, this group demonstrates the speciation potential for early colonizers to young islands chains where there is still an abundance of ecological niches to occupy. The group is believed to have invaded the islands more than 15 million years ago, long before any of todays high islands emerged out of the ocean. Hyposmocoma are well known for their unique larvae which construct silken cases carried with them as a form of shelter. Phylogenetically speaking, the different species of Hyposmocoma form clades (monophyletic groups) based on their case types. This means that all of the species of one case type, are more closely related, regardless of their island of origin, than they are to other species of Hyposmocoma with different case types but from the same island of origin. Hyposmocoma are also ecologically unique among the lepidopterans. Species are found in terrestrial and aquatic habitats (amphibious capabilities are thought to have evolved independently three times); they can be carnivores, herbivores or detritivores; and one species of Hyposmocoma is the only lepidopteran known to feed on molluscs, in this case snails. Please help us transcribe the UHIM specimens from this highly unique and evolutionarily valuable endemic radiation of Hyposmocoma moths! The total number of tasks for this dataset is: 591, number transcribed is 591 and number validated is 0.

潜蛾属(Hyposmocoma)是一类高度多样的微鳞翅类昆虫(micro-lepidopterans),为夏威夷群岛特有类群。该类群已描述物种超300种,推测现存物种超600种,其展现出年轻岛链中早期拓殖物种的物种形成潜力——彼时岛链仍存在大量未被占据的生态位。据推测,该类群在1500多万年前便已入侵夏威夷群岛,远早于现今多数高岛浮出海面的时间。 潜蛾属昆虫以其独特的幼虫著称:幼虫会构筑丝质巢室并随身携带,以此作为庇护场所。从系统发育角度来看,潜蛾属的不同物种会根据其巢室类型形成演化支(clade,单系群)。这意味着,无论其原产地岛屿为何,同一巢室类型的所有物种间的亲缘关系,都比它们与来自同一原产地岛屿但巢室类型不同的其他潜蛾属物种更为密切。 潜蛾属在鳞翅目昆虫中同样具有独特的生态特征:其物种可栖息于陆生与水生环境(两栖能力被认为独立演化了三次),食性涵盖食肉、植食与腐食;其中一种潜蛾属物种是目前已知唯一以软体动物(此处为蜗牛)为食的鳞翅目昆虫。 恳请协助我们转录该组兼具独特性与进化研究价值的特有辐射演化潜蛾属(Hyposmocoma)蛾类的UHIM标本!本数据集的总任务量为591项,已完成转录591项,待验证0项。
