報告者：ナハラゲ、チャーマリ AD
期間：２００７年１月１０日 〜 ２００7年３月２０日
スリランカに生息する４種の霊長類（スレンダーロリス、ハヌマンラングール、カオムラサキラングール、トクモンキー）の広域分布情報を更新するため、全国のアンケート調査回収済みの資料分析を開始した。
また、１５日間をかけて、霊長類の分布情報が乏しい地域（ブンダラ国立公園：２月５?７日、ヤラ国立公園：２月９?１２日、ウダワラワ国立公園：２月１２?１４日、ホートンプレンズ国立公園：２月１４?１７日やお寺等の生息地）を調査した。調査中、現地聞き込みおよび野外観察、寄生虫感染・DNA解析用の糞サンプル（N=
104）の採集や写真撮影を行った。さらに、コロンボ地区内のカオムラサキラングールの調査と分布に関する聞き込み調査を行った。
From 7 January to 4 February, I worked at the University
of Sri Jayawardenepura analyzing questionnaires returned so far by
undergraduate students in my department. Also I went to the library and
collected literature on primates from historical Buddhist literature. I
also conducted a preliminary survey of the distribution of the
purple-faced langur in Colombo district by direct observation and by
asking fellow colleagues in the university whom live across the
district.Between 5 and19 Feb., I started the extensive field survey with
Prof. Michael Huffman and two local counterparts, Ms. K.M.P. Nadeera
(officer, Department of Wildlife) and Ms. W. Tharindi (graduate in
Anthropology, Univ. Sri. Jayawardenepura). We visited 12 sites in the
western, southern and central provinces of Sri Lanka known to contain many
primate populations. We left Colombo on 5 February for Bundala National
Park in the south. There between 5 and 7 Feb., we observed toque macaques
and gray langurs. Between 7 and 9 Feb. we visited four temple complexes:
Vadasitikanda, Sellakataragama, Kataragama and Situlpawwa. Here we
collected fecal samples from troops of toque macaque and hanuman langur
when encountered. From 9 to 12 Feb. we stayed in Yala NP and conducted
surveys and collected fecal samples from toque macaques and hanuman
langurs. We next moved north to Udawalawa NP and stayed there between 12
and 14 Feb. were we again observed toque macaques and hanuman langurs.
From 14 Feb. we moved further north to the highlands of Horton Plains NP,
the highest national park in Sri Lanka. Between 14 to 17 Feb. we conducted
surveys on the high-altitude sub-species of purple faced langur (bear
monkeys). On 18 Feb. we visited the Kandy City suberbs, Udawatta Kele
Nature Sancturay and the Peradeniya Botanical Gardens to collect toque
macaque fecal samples and conduct questionnaires on local residents. On 19
Feb. we visited Dambulla in the north central part of the island site to
collect toque macaque fecal samples. This temple complex is a World
Heritage site.Prof. Huffman returned to Japan on 25 Feb. From 20 Feb. to
17 March I visited University of Sri Jayawardenepura to conduct
preliminary studies on two troops of the lowland sub-species of purple
faced langurs ranging on the campus grounds and nearby neighborhood. I
followed them and collected fecal samples and took photos when ever
possible. I left Colombo for Nagoya on 18 March arriving back in Nagoya
via Singapore on 20 March.
