中文摘要 | 利用昆蟲碎片,鑑定關刀溪長期生態研究站之華南鼬排遺中昆蟲的類群,在1997年63件華南鼬排遺樣品中,含有昆蟲的樣品46件佔73.0%;以單季而言,冬季33件樣品中,含昆蟲的樣品24件也佔72.7%;就各目昆蟲組成而言,直翅目佔全年有昆蟲樣品之54.3%;在所檢視1997年之27件排遺樣品中,除直翅目外之其餘各目昆蟲所佔的百分比分別為:鞘翅目44.4%、革翅目22.2%、膜翅目18.5%、雙翅目74%、半翅目3.7%、蝨目3.7%。在27件排遺樣品中殘存的昆蟲碎片,以頭部的觸角19.8%最多,大顎9.9%其次,胸部以足13.2%最多,其次為翅5.0%,而腹部則以尾毛12.4%最多,產卵管9.1%次之。 |
英文摘要 | Insect preys of the Mustela sibirica inhabiting Guandaushi forest ecosystem, the LTER site at central Taiwan, were studied by fecal analysis. Insect fragments could be found in 46 (73%) out of the 63 fecal samples collected in 1997. Among the 33 samples collected in winter, 72.7% have insect fragments inside. Orthoptera was the major insect prey for the weasels. Fragments of Orthoptera could be found in 5430 of the 46 specimens with insect fragments. In addition to Orthoptera, fragments belonging to six other insect orders were identified among the 27 specimens examined. The percentages of occurrence of these orders were: Coleoptera 44.4%, Dermaptera 22,2%. Hymenoptera 18.5%. Diptera 7.4%, Hemiptera 3.7% and Anoplura 3.7%. Exoskeletal fragments of certain body parts were preserved better and were more easily identified in fecal specimens than those of other body parts. Among the 27 feces of 1997, the percentages of occurrence of fragments of various parts were: Headantenna, 19.8%; mandible, 9.9%; Thorax-legs, l3.2%; wings, 5.0%; and Abdomen-cerci, 12.4%; ovipositors, 9.1%. |
