摘要
研究了贵州省西南部树鼩的分类地位、地理分布、生态环境以及野外自然条件下的繁殖和食性等生物学特性。确认贵州树鼩统属中缅树鼩滇南亚种(Tupaia belangeriyunalis Thomas)在贵州西南盘江流域各县均有分布,修正了《贵州省脊椎动物分布名录》(1979)所记载的仅分布于兴义的海南亚种记录。野外自然条件下繁殖期集中在7～8月,怀孕树鼩胚胎一般4个,食性仍以昆虫为主。
The geographical distribution, natural habitats, feeding habits, and repro duction of tupaiidae, Tupaia belangeri yunalis. were observed in southwestern Guizhou. It is found that tupaiidae is mainly distributed in Xingyi, Anlong, and Ceheng counties along Panjiang River Valley, at latitude 24°40′-25°1′N, longitude 104°37′-106°10′E, and 570-1350 meters above sea level. Subtropical monsoon forests are the main habitats. The reproduction, months are July to August under natural conditions and a pregnant tupaiidae Carries four embryos on average. The analysis of stomach contents of tupaiidae caught in the field shows that their food mainly consists of inses belonging to Homoptera, Hymenoptera, and Isoptera, Classification of tupaiidaeis discussed, T. b. yunalis was once considered to be T. b. modesta for many years but, the author holds that it is a distinguishable subspecies from T. b.modesta.
