  1. Both oxyopes sertatus and harpactor fuscipes are important predators of common cutworm ( spodoptera litura ) on tobacco. the effect of several interference factors on the predations of o. sertatus and h. fuscipes on the larvae of s. litura were examined in laboratory. the results indicated that there were significant mutual interferences on their predations with the existence of other individual in the same / different species. as the number of the predator increased, the predation rates decreased significantly. the interference coefficients ( m ) within h. fuscipes and within o. sertatus were 0. 7278 and 0. 6911, respectively, while the interference coefficient ( m ) between o. sertatus and h. fuscipes was 0. 9464. these results showed that the effect of mutual interference on predation in interspecies was more obvious than that in intraspecies. the number of prey captured and the predation rate of predator dropped with increasing the number of tobacco stalks. this result suggested that spatial heterogeneity was also an important factor affecting the predation of predator on prey

    斜紋貓蛛和紅彩真獵蝽均是煙草上斜紋夜蛾的重要捕食性天敵.室內測定幾種干擾因素對斜紋貓蛛和紅彩真獵蝽捕食作用的影響，結果表明這些干擾因素對斜紋貓蛛種內、紅彩真獵蝽種內和兩種捕食者種間的捕食作用均有明顯的干擾作用，隨捕食者數量的增加，其對斜紋夜蛾捕食作用率顯著降低.斜紋貓蛛種內的干擾系數和紅彩真獵蝽種內的干擾系數分別為0 . 7278和0 . 6911 ，而兩者種間的干擾系數為0 . 9464 ，說明兩者種間的干擾作用要明顯高於同一種捕食者種內的干擾作用.兩種捕食性天敵對斜紋夜蛾的捕食量和捕食作用率隨煙草莖桿數的增加而降低，表明空間異質性同樣是影響兩種捕食性天敵捕食作用的一個重要因素

  4. Among them, euphausia pacifica, pseudeuphausia latifrons and p. sinica are dominant species that play a key role in the china sea. by means of the vertical slab polyacrylamide gel electrophoresis, genetic heterogeneity of three krill was investigated, in order to elucidate the genetic diversity and differentiation among them

  5. The coexistence mechanisms of industry populations are mainly discussed in terms of small spatial scale : the latent species pool coexistence mechanism in a specific temporal and spatial scope ; the coexistence mechanism under the condition of niche regeneration caused by competitiveness ; the coexistence mechanism under the condition of the formation of adaptive temporary niche caused by similar competitive capability ; the pre - occupied and lottery coexistence mechanism under the condition of the faultage of resources ; the coexistence mechanism through transfer and diffuseness in the heterogeneity survival environment

    上述機制完備地闡釋了產業族群的競爭共存現象，其中，斷層預佔在報酬遞增規律支配下的新經濟時代具有重要的價值，而「以創新的方式形成相似的競爭能力是產業族群競爭共存的重要條件」等結論同樣是令人感興趣的。
  6. The area in question has great conservation value as following aspects : the population of butterfly shows great species abundance ; the heterogeneity of habitat revealed by the presence of multi - subspecies and multi - morphological species provides animals a steady habitat ; the faunal character and vertical distribution of butterflies show great value of ecological study ; the mid - mountain 8002600 ? m that has better environmental condition and less human disturbance is a typical

    秦嶺對東洋種的阻隔作用大於對古北種的作用。中山地帶8002600m即暖溫帶落葉闊葉林和中山針闊葉混交林帶環境狀況良好，氣候條件優越，受人為干擾少，因而物種豐富多樣性較大。研究地區具有很高的保護價值。
