中文拼音 [chìmùduōxìng]
翅目多性
英文
lepidopteran diversity-
Staphylinidae is one of the largest family in coleoptera, they occupy a wide variety of habitats and have a wide range of food - habits. they are essentially carnivorous ( insect feeder ), but some groups have become evolved as mycophagous, coprophagous, coprophagous, carpophagous, pollinophagous and so on. some species have adapted to a parasitism of mammals
隱翅蟲是一類廣泛分佈於農田、森林和山區的鞘翅目昆蟲,它們生境多樣,有的為肉食性種類,是捕食農林害蟲的重要天敵,也有藥用種類和衛生害蟲,還有取食動植物有機殘體、促進自然界物質循環、保持生態平衡的種類,與人類的關系密切,是一類不可忽視的自然資源。The ants " quantity is 2203, and whose dominance index is 0. 2832. the quantit y of the rove beetles of the coleoptera is 1619, and whose dominance index is 0. 2081. the pyralids moths and outlet moths of the lepidoptera, the leafhoppers of the homoptera, the darking beetles of coleptera and blow flies of the diptera take the dominant place in moderate insect community
中性昆蟲群落中,以膜翅目蟻科種類及數量最多,其群落數量為2203頭,優勢度指數為0 . 2832 ;其次是鞘翅目隱翅甲昆蟲,數量為1619頭,優勢度指數為0 . 2081 ;再次是鱗翅目的螟蛾、夜蛾,同翅目的葉蟬,鞘翅目的擬步甲,雙翅目的麗蠅等昆蟲。The diversity index showed that neca > pca > cka, and so did the evenness index. the dominant concentration index showed that cka > pca > neck. so the stability of the arthropod community in neca is best and that in cka is worst in the three areas
同時,常規對照棉田中時有發現的紅鈴蟲( peetinophoragossypxellasaunders ) 、玉米螟( ostriniafurnaeali : ( euenee ) ) ,在轉bt墓因棉田中沒有發生,表明轉bt基因棉對棉田中大多數鱗翅目害蟲具有良好的抗性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分享友人
