Abstract A pen-tailed tree shrew (Ptilocercus lowii) specimen was live-trapped in 2006 in an Acacia plantation for the first known time at Samarakan Planted Forest Zone (PFZ) in Bintulu, Sarawak. However, its lack of recurring in other Acacia plantations suggests that the monoculture agricultural field is not a typical habitat for this species. Live-trapping data suggest that generally there were two breeding seasons per year for this species in Borneo: a more consistent one occurred between February and April, and a broader one between June and October. The second, the broader breeding season likely varied based on the microhabitat of each sampling site. In Samarakan PFZ, during the 2006 season, we recorded one breeding season between September and October, and in 2007 recorded one between June and July. Meanwhile, since the year 2000, this species was recorded at only 17 locations within its range of distribution in Southeast Asia, suggesting the possibility of population decline and shrinkage in its distribution range. Given the rapid disappearance of forested areas in Southeast Asia, stepping up the field studies and targeted sampling for this species becomes the priority task for all of its conservation work.

重新审视笔尾树鼩Ptilocercus lowii的习性、发生、繁殖季节和保护

摘要 2006 年，在砂拉越民都鲁的 Samarakan 人工林区 (PFZ) 的金合欢种植园中，首次活捉了一只笔尾树鼩 (Ptilocercus lowii) 标本。然而，它在其他金合欢种植园中没有出现，这表明单一栽培的农田不是该物种的典型栖息地。实时捕获数据表明，婆罗洲该物种通常每年有两个繁殖季节：一个更一致的季节发生在 2 月和 4 月之间，而更广泛的一个发生在 6 月和 10 月之间。第二，更广泛的繁殖季节可能因每个采样点的微生境而异。在 Samarakan PFZ，在 2006 年的季节中，我们在 9 月和 10 月之间记录了一个繁殖季节，2007 年在 6 月和 7 月之间记录了一个繁殖季节。同时，自 2000 年以来，该物种仅在其东南亚分布范围内的17个地点被记录，表明其分布范围可能会减少和缩小。鉴于东南亚森林地区的迅速消失，加强对该物种的实地研究和有针对性的采样成为其所有保护工作的首要任务。
