Biosynthesis of 1-alkenes in the defensive secretions ofTribolium confusum (Tenebrionidae); stereochemical implications

Summary The terminally unsaturated hydrocarbons of the defensive secretion ofTribolium confusum are biosynthesized from fatty acids by oxidative decarboxylation. The process involves an enantiospecific cleavage of the C–H bond of thepro-(S) C(3)–H atom and simultaneous decarboxylation of the acid into an 1-alkene and carbon dioxide via ananti-periplanar transition state geometry (anti-elimination). The stereochemistry of this biotranformation is identical in all respects with the same reaction in higher plants. The mechanism seems to be of general importance for the biosynthesis of many vinylic substructures of natural products from oxygen-containing precursors.

宁夏贺兰山拟步甲科的区系组成与生态分布

为了研究宁夏贺兰山国家自然保护区的生物多样性,于2007-2009年在宁夏贺兰山进行了系统的拟步甲科标本采集．结果表明,共获得标本4000余只,经分类鉴定出50种,隶属4亚科20属,其中,拟步甲亚科种类最多,计11属24种,占总种数的48％,漠甲亚科次之,计7属20种,占总种数的40％．从世界动物区系的构成来看,以中亚亚界成分为主;从中国动物区系的构成来看,贺兰山拟步甲科昆虫区系具有明显的蒙新区系特征,并且与华北区区系较为密切,与青藏区系次之,7个区系分布型中以蒙新区所占比例最高,共有32种,占64％,其次为蒙新区＋华北区区系分布型,计10种,占20％．根据拟步甲科生态分布特征,并结合植被、地形、地貌,运用等级聚类分析将50种拟步甲科划分为4个生态种组;拟步甲科随贺兰山垂直植被带分布表现差异,山麓荒漠草原带和疏林草原带是主要的分布带,喜阴湿的种类主要分布在针阔混交林带以上．     

A biogeographical analysis of the tenebrionid beetles (Coleoptera,Tenebrionidae) of the island of Thasos in the context of the Aegean Islands (Greece)

This research aimed to study the origin and the biogeographical relationships of the tenebrionid beetle (Coleoptera, Tenebrionidae) fauna of the island of Thasos, with reference to the other Aegean Islands. A total of 32 Aegean Islands and 170 taxa (species and subspecies), 23 of which occur on Thasos, were included in this study. Nine tenebrionid species are here reported for the first time from Thasos, including the first records of Platydema europaeum and Nalassus plebejus from the Aegean Islands. Several models (linear, exponential, power, logistic, Gompertz, Weibull and Lomolino functions) were used to test the species–area relationship. The power function appeared to be the most appropriate model and the parameters of the curve suggest a possible relict character for this fauna. The proportion of Balkan taxa on the islands sharply decreases from west to east, whereas the Anatolian taxa follow an opposite trend. Multi‐dimensional scaling, Parsimony Analysis of Endemicity and discriminant function analysis revealed a clear faunal discontinuity between the western and central Aegean Islands on one side, and the islands close to the Anatolian coast on the other. This discontinuity, consistent with the persistence (from Messinian to Pleistocene) of a sea barrier between these two groups of islands, strongly supports the importance of Pleistocene island configurations in determining present distributional patterns. The comparative richness of the tenebrionid fauna on Thasos is enhanced by the proximity of the island to the mainland and the diversity of its surviving habitats.
