事業報告事業番号：20-009 バングラディシュにおけるアカゲザルの比較社会生態学的研究 報告者：ジャマン モハマド フィロズ 期間：2008/05/08 - 2008/06/29 博士課程研究のため、バングラディシュに生息するアカゲザルの野外調査及び研究連絡を行った。 I traveled a second time (summer field season) in Bangladesh for data collection on rhesus macaques for part of my doctoral course. It was an excellent opportunity to study free-ranging rhesus monkeys in my home country. I did observations on two free ranging rhesus groups, one living in the urban area (Shadhona population) located in Dhaka City and another one group living near a village (Bormi population), located in the Shripur, Gazipur District. The aim of this field trip was to collect baseline data on behavioral activity budgets and the feeding ecology of the species in terms of age-sex class differences and seasonality in rhesus macaques in that geographical region. I observed 23 days for the Shadhona population and 24 days for the Bormi population to collect behavioral and ecological data on rhesus macaques in two separate environment and locations. This time I collected 22,450-min. focal samples sessions, including over 374.1 hours of focal data, video records and pictures of the monkeys and their habitats. I sampled the vegetation to see the food availability in that area for monkeys. To get advice and comments I made a discussion session about my research with my colleagues and other researchers in the Department of Zoology, University of Dhaka on 28 June, 2008. I left Dhaka, Bangladesh in the early morning on 29 June, and arrived in Japan in late afternoon on 29 June. 2008.
