結果表明，月份對天牛群落組成影響顯著，天牛的發生具有明顯的季節性；生境類型對天牛群落組成也有很大影響，體現了天牛對寄主植物的依賴性；海拔對天牛群落組成的影響較小，這與天牛幼蟲終生生活在寄主植物莖內，受外界環境影響較小有關。The research result is following : the annual species richness index of studied forest plant community averaged 64. 688, the species diversity index was 2. 982. the proportion of every functional group of forest plant community is : herbaceous layer ( average is 68. 89 % ) > tall tree layer ( average is 15. 266 % ) > shrub layer. ( average is 15. 845 % ) the proportion of every functional group in forest insect communities is remarkably different, and the order of the proportion is herbivorous insect group ( average 0. 729 ) > predatory natural enemy insect group ( average 0. 136 ) > parasitical insect group ( average 0. 135 ). with seasonal change, the proportion of herbivorous and predatory insect group decreased obviously, while that of parasitical insect group increased on average by 147 %
研究結果如下：森林植物群落種的全年物種豐富度指數平均為64 . 688種，多樣性指數為2 . 982森林植物群落內各功能類群物種所佔比重依次為：草本層（平均為68 . 89 ） >喬木層（平均為15 . 266 ）灌木層（平均為15 . 845 ） 。森林昆蟲群落中，全年各功能類群所佔比重以植食性昆蟲類群為最大，平均佔0 . 729 ；捕食性昆蟲類群次之，平均佔0 . 136 ；寄生性天敵類群為最小，平均為0 . 135 。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 present paper deal with the population dynamycs of liriomyza huidobrensis and its parasitic enemies using fuzzy grouping analysis
摘要應用模糊聚類方法研究了南美斑潛蠅及其寄生蜂的種群動態。The character of the colonies is important for special species. the results show that the characters of conidia shape and color are very important, the steady number of distosepta and the size of conidia are important too. otherwise, the special hosts corresponding to the species help us identify these species
以分生抱子的形態特徵為主，菌落特證僅對特殊的種有參考價值：以分生袍于的假隔膜數的差異分成大的類群，分生泡于的顏色、形狀是主要的分類依據：形狀相似時，長、寬作為區分的參考；此外，有些種具穩定的寄主，寄主也可作為鑒定的重要參考依據。Study on flea communities of the rodent in dongling mountain in beijing
