构建准确、有效的物种遗传信息库并运用其作为主要的物种鉴定检索数据库,是新一代植物志(iFlora)与传统植物志的本质区别。采集并准确鉴定数以万计的植物样品用于建立遗传信息库存在一定困难,随着遗传信息获取技术的快速发展,使馆藏植物标本成为获取遗传信息的重要补充,并具有提升遗传信息库建设速度和可靠性的较大潜能。本文结合已有的研究和实验室多年工作实践,论述了植物标本作为iFlora物种遗传信息提取材料的可行性和不可替代性;总结了标本遗传信息提取过程中的主要困难和存在问题,并提出一些解决方法;阐述了使用馆藏标本特别是利用模式标本材料构建遗传信息标准库对iFlora构建的重要作用和意义。 相似文献

Abstract The second species of the genus, Macroasteropteron chathamensis sp. nov. is described in the present paper. It was collected from 1000 m depth during the New Zealand national biodiversity programme Ocean Survey 20/20 to the Chatham Rise and the Challenger Plateau. To accommodate this genus, a new subfamily Macroasteropteroninae is described herein. It is defined by the following autapomorphies: locking system on the shell; very small second segment on the second antenna (bearing no dorsal bristles); square shaped third and fourth segments on the same appendage; absence of dorsal bristles on the third segment of the male clasping organ; reverse position of the alpha and beta bristles on the maxillula; almost square shaped skirt on the sixth limb; and a bulbous terminal part of the seventh limb, which, in addition, does not have any bell-bearing bristles. A key to the four subfamilies of Cylindroleberididae is provided. 相似文献

Abstract Opportunistic sightings and strandings of Caperea marginata (n=196) from the vicinity of Australia and New Zealand (1884 to early 2007) were used to relate geographic and temporal patterns to oceanographic and broad-scale climatic variability. Records were not uniformly distributed along the coast and more (69%) were from Australia than New Zealand. Seven coastal whale ‘hotspots’ were identified which accounted for 61% of records with locality data. Half of the hotspot records were from southeast (37) and northwest (20) Tasmania—others each had 9–15 events. Upwelling and/or high zooplankton abundance has been documented near all whale hotspots. Records of C. marginata occurred in all months, with 75% in spring and summer. Inter-annual variability showed broad agreement between increased whale records (usually in spring/summer) and strongly positive ‘Niño 3.4’ during 1980–1995 but not thereafter. Coastal upwelling and productivity increase during climatic phenomena such as El Niño and are likely to be quickly beneficial to plankton-feeding whales such as C. marginata. 相似文献

In a three-hour bioassay, we tested the palatability and feeding preferences of Uresiphita maorialis (kōwhai moth) for Sophora tetraptera, Sophora microphylla and Sophora prostrata. Palatability tests showed no differences among the Sophora species. Feeding preferences, on the other hand, showed that S. tetraptera and S. microphylla leaves are preferred over S. prostrata leaves. Our results support our field observations in Wellington city parks and gardens showing that S. tetraptera and S. microphylla plants frequently have higher densities of larvae than S. prostrata. 相似文献

Nearly 20 000 specimens of pseudoscorpions from a full range of habitats have been examined. For New Zealand, 70 species and subspecies in 28 genera are recognised, and for Norfolk and Lord Howe Islands, 11 species in 9 genera. Endemism is very high in this area: in New Zealand, 13 out of 25 indigenous genera are endemic; 2 others (Apatochernes, Nesochernes) are shared with Norfolk Island; and 4 (Sathrochthonius, Austrochthonius, Synsphyronus, Protochelifer) extend their distribution to Australia (Austrochthonius is known also from South America and South Africa). The rest of the native genera have a wider distribution in the Pacific. Three species (Lamprochernes savignyi, Withius subruber, Chelifer cancroides) have a wide and disjunct distribution induced by human traffic, and are considered to be an introduced element. 相似文献
