根據1998 2000年作者在廣西南部山區的採集，結合中國科學院動物研究所昆蟲標本館館藏標本的研究，報道了該科4亞科27屬81種在廣西的分佈，其中， 4屬60種是中國新紀錄.本文對前人和作者最近對中國姬小蜂科的分類研究簡單作了綜述，並對廣西的姬小蜂科物種進行了初步的組分分析.根據現有材料得出結論是: 1 ）廣西的姬小蜂科區系成分以東洋區和古北區成分為主; 2 ）多個區系成分分佈相互重疊、交錯Scientists have sequenced the honeybee genome, revealing some of the biology beneath the insects ' advanced social systems and powerful sense of smell as well as the spread of africanized ( or " killer " ) strains
科學家已經為蜜蜂的基因完成了排序，同時也揭示出這種昆蟲高度社會化系統、發達的嗅覺以及非洲殺人蜂的泛濫背後的生物特性。Abstract : biological invasions are a continuous feature of a non - equilibrium world, ever more so as a result of accidental and deliberate introductions by mankind. while many of these introductions are apparently harmless, others have significant consequences for organisms native to the invaded range, and entire communities may be affected. here we provide a survey of common models of range expansion, and outline the consequences these models have for patterns in genetic diversity and population structure. we describe how patterns of genetic diversity at a range of markers can be used to infer invasion routes, and to reveal the roles of selection and drift in shaping population genetic patterns that accompany range expansion. we summarise a growing range of population genetic techniques that allow large changes in population size ( bottlenecks and population expansions ) to be inferred over a range of timescales. finally, we illustrate some of the approaches described using data for a suite of invasions by oak gallwasps ( hymenoptera, cynipidae, cynipini ) in europe. we show that over timescales ranging from 500 10000 years, allele frequency data for polymorphic allozymes reveal ( a ) a consistent loss of genetic diversity along invasion routes, confirming the role of glacial refugia as centres of genetic diversity over these timescales, and ( b ) that populations in the invaded range are more subdivided genetically than those in the native range of each species. this spatial variation in population structure may be the result of variation in the patchiness of resources exploited by gallwasps, particularly host oak plants
文摘:生物入侵是不均衡世界的一個永恆話題，尤其是當人類有意或無意地引入物種后.很多引入顯然是無害的，但另外一些則有著嚴重的後果，會給入侵地的生物以至於整個生物群落造成影響.本文總結了分佈區擴張的常見模式，概述了它們對遺傳多樣性和種群結構式樣所造成的影響.描述了如何根據以一批遺傳標記所得到的遺傳多樣性式樣來推斷入侵途徑，來揭示伴隨擴張選擇和漂變在形成種群遺傳樣式中的作用.本文對日益增多的群體遺傳學方法進行了總結，這些技術可以用來在不同的時間尺度上推斷種群規模所發生的巨大變化（瓶頸效應及種群擴張） .最後，我們以歐洲櫟癭蜂（膜翅目，癭蜂科，癭蜂族）一系列入侵的數據為例對一些方法進行了說明.從500 10000年的時間尺度上，多態的等位酶位點上等位基因頻率的數據表明: 1 ）遺傳多樣性沿入侵路線呈不斷下降的趨勢，支持了冰河期避難所作為遺傳多樣性中心的作用; 2 ）入侵地區的種群與該物種原產地的種群相比，遺傳上的分化更為強烈.這種種群結構在空間上的變異可能是被櫟癭蜂開發的資源尤其是櫟樹寄主在斑塊上出現變異的反映The chinese market is moving towards the internationalization, while facing the competitor swarming forward and the opportunity of going out, chinese enterprises should set up one ' s own strategic alliances as soon as possible, strengthen the national and international competitiveness of our enterprises. of course, one series of scientific, practical method should be carried on as the theory instruct. based on both home and international studies about strategic alliances, the dissertation starts with the basic conception of the relationship management of the strategic alliance, then give an all - round explaining to the relationship management of the strategic alliance and analyze the risk factors of strategic alliance that exist in the relationship management, and then structure the grey correlation and neural network model to appraise the performance of the relationship management, and combine with realistic reasons that lead to the failure of the strategic alliances, finally use the models mentioned above to analysis a real example to distinguish the influence primary and secondary factors to relationship management of the strategic alliances and offer references to boost the rate of successful strategic alliances and improve the strategic alliances " benefit
