摘要
为研究分解利用小型鸟类尸体的主要动物类群,比较其对尸体的利用情况和分布差异,在我国东北黑龙江省尚志市帽儿山林场投放120只死亡的雏鸡,通过捕虫及红外相机监控等方法记录到所有出现的动物种类共计5纲8目18科28种。尸体于投放第8天全部丢失,其中针阔混交林中尸体丢失的速度最快,投放第1天的存留时间期望值最低;阔叶林、人工红松林次之;草地尸体丢失的速度最慢,存留时间期望值最高。尸体的丢失可分为被埋葬虫掩埋、被鸟兽食用和被蝇类幼虫食用3种情况,其中被埋葬虫埋葬的尸体占55%,被鸟兽食用的尸体占12%,被蝇类幼虫食用的尸体有占33%。埋葬虫完全利用尸体的速度最快,数量占55%;鸟兽次之,蝇类最慢。埋葬虫主要分布在针阔混交林和阔叶林,而草地生境无分布。
We disposed of 120 dead chickens in Maoershan Forest Farm of Shangzhi City, Heilongjiang Province, to investigate the fauna utilizing small avian carcasses. We compared the utilization and distribution of the fauna. We recorded 28 species of 8 orders and 18 families by insect sampling and infrared camera. All bodies disappeared by the 8th day. The body disappeared fastest in theropencedrymion, with the lowest expected retention time during the first day of disposal. This was followed by broad -leaved forest and planted Korean pine forest. Chickens disappeared most slowly on grassland, with the highest expected retention time. Bodies were buried by carrion beetles（55% ）, eaten by birds and animals （12%）, or eaten by fly larvae （33%）. Carrion beetles used the body completely the fastest, followed by birds and mammals, flies were the slowest. Carrion beetles were recorded mainly in theropencedrymion and broad - leaved forest, but not in grassland.
