项目摘要

This research aims to investigate behavioral ecology of the Asian elephant and the Indian peafowl living in the dry-zone in South-East Sri Lanka. For the Asian elephant, we focused on the mechanism of human-elephant conflict (HEC). For the Indian peafowl, we aim to clarify their mating system in the natural populations. During the study periods, we conducted our field work 10 times in total : in 2003, T Hasegawa & Campos in August, Takatsuki in September, T & M Hasegawa from December to January ; in 2004, Takatsuki in March, Takatsuki and Campos from May to June, Campos from July to August, Ransirini in October, T Hasegawa, Saito, Suetsugu from October to November, T Hasegawa in December ; Campos from December to January. The main results are obtained about HEC research in which we allocate local field assistants in five villages where elephant frequently raid crop fields. Data were accumulated monthly about elephant ecology damage caused by the elephants, human responses and so on. We also attached a GPS transmitter for one big male elephant that were ranging in research area in April 2005. In spite of long preparation, we could receive data by unknown reasons. DNA analyses from fecal samples were also tried both in field and in zoos in Japan. Although we successfully found some haplotypes among Asian elephants, it is still difficult to collect individually-identified dung samples in the field. On peafowl research, it took some time to find suitable site to observe because peafowl are too shy to be observed. Finally, we could find good location where we can observe their natural behavior over the pond. Compared with Japanese population, males' courtship territories disperse more widely in the natural population in Sri Lanka. Rate of male vocalization is also measured and analized.

这项研究旨在调查亚洲大象和印度孔雀的行为生态学，居住在斯里兰卡东南部的干区。对于亚洲大象，我们专注于人类大象冲突的机制（HEC）。对于印度孔雀，我们旨在阐明他们在自然种群中的交配系统。在研究期间，我们总共进行了10次现场工作：2003年，七月，七月的Takatsuki，T＆M 12月至1月。 2004年，三月份的通田和坎波斯从5月到6月，七月至八月，10月，兰西里尼（Ransirini），十月至11月，十月，塞特ugu（Suetsugu），12月，塞特古（Suetsugu）坎波斯从12月至1月。关于HEC研究的主要结果是我们在五个大象经常突袭作物场的五个村庄中分配地方野外助手。每月累积有关大象，人类反应等造成的大象生态损害的数据。我们还为2005年4月在研究区域范围内的一头大象的GPS发射器附加了一个GPS发射器。尽管准备长时间，但我们可以通过未知的原因收到数据。来自粪便样品的DNA分析也在日本的田间和动物园中尝试。尽管我们在亚洲大象中成功发现了一些单倍型，但仍很难在该领域收集单独识别的粪便样本。在孔雀研究中，花了一些时间来寻找合适的地点来观察，因为孔雀太害羞了，无法观察到。最后，我们可以找到可以在池塘上观察其自然行为的好地方。与日本人口相比，男性的求爱领土在斯里兰卡的自然人口中更广泛地分散。还测量和分析了男性发声的速度。
