  7. 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.本文對日益增多的群體遺傳學方法進行了總結,這些技術可以來在不同的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對一些方法進行了說明.從500 10000年的尺度上,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為遺傳多樣性中心的; 2 )入侵地區的種群與該物種原產地的種群相,遺傳上的分化更為強烈.這種種群結構在空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

  15. Business valuation based on modern economy is one of the most difficult and comprehensive professional work in asset appraisal, but also stands for the trend of the appraisal. as china implemented planned economy all the long in the past years, the concept of business value was proposed later than other advanced countries. the study on the theory and method of business valuation we made is relatively backward. all these lead to that we merely use cost method in practice. with the improvement of market economy, the validity of cost method is challenged. hunting for appraisal methods suitable for china circumstance has become more and more urgent. this thesis presents its own opinion on the adjustment of the basic frame of theory of business valuation. for the first time, it puts systems theory into the study of the theory base, and believes that the enterprise as a compound entity has higher efficiency than the sum of its constituent, and then proposes new appraisal assumption. aiming at the obscure understan ding, it analyses a group of conception related to business valuation. after giving a whole analysis and study, this thesis indicates the income approach which emphasizes earning - capacity of a enterprise should become the correct choice of china, and makes a further study on the origin - features and feasibility of this method

    植根于現代經濟的企業價值評估是資產評估中綜合性最強,技術難度最高的業務之一,也是評估業未來的發展方向,由於我國過去長期實行計劃經濟體制,企業價值概念的提出和運較晚,缺少現代經營理念的積累,企業價值評估的理論與方法的研究較滯后。本文試圖以理性分析和案分析相結合的方法,系統研究和分析企業價值評估的基礎理論及其現實條件下,適應我國經濟發展的評估方法,以期為構建有中國特色的企業價值評估理論和方法體系做一些有益的探索。文章以企業價值評估的基本概念為起點,在對眾多關于企業性質的學說和理論觀點進行概括抽象的基礎上,指出了整體性、持續經營和盈利性是企業的重要特徵,依據企業的整體性運系統方法闡明了企業的價值大於組成企業的單項資產價值之和,據此提出了反映企業價值評估特點的有機組合增殖假設;依據盈利性的特點,強調了企業價值評估的核心應為企業的獲利能力,而不是組建企業的成本;對企業價值、企業價值評估含義、特點的論述以及對相關概念的辨析表明了者的個人觀點和文章的基本定位,而從評估目的入手劃分的以產權變動為目的的企業價值評估和以財務決策為目的的企業價值評估與企業價值評估的假設、評估核心共同決定了評估方法的選
