Animal Community, Environment and Phylogeny in Lake Baikal

“贝加尔湖动物群落、环境和系统发育”研究由16名日本科学家(包括3名辅助科学家)和5名俄罗斯科学家在以下7个研究项目中完成；(1)对塞伦加三角洲采集的脊椎动物(桡足纲、端足类和海绵类)的分类和生态学研究；(2)利用原始标本和博物馆标本进行了不同专业的脊椎动物属的形态和生物分子研究；(3)利用原始标本和博物馆标本从解剖学、生活史和分子生物学的角度研究了科的鱼类群；(4)从南方迁徙到西伯利亚地区的鸟类中有机氯化合物的污染研究；(5)对多氯联苯、滴滴涕、六六六、汞、镉、铅等化学物质的环境研究。(6)贝加尔湖生态系统的稳定同位素研究；(7)利用原始标本和博物馆标本，对比加尔湖的Pusa sibilica、里海的Phoca caspica和北冰洋的Phoca hispida三个亚属的物种进行了形态和分子生物学研究。这些成果以41篇原创科学论文、5本图书和7篇文献的形式发表，并在44次科学会议上发表。

The study "Animal Community, Environment and Phylogeny in Lake Baikal" was made in the following 7 research items by 16 Japanese scientists (including 3 supporting scientists) and 5 Russian scientists ; (1) taxonomical and ecological study on invertebral animals (copedoda, amphipoda, and sponges) collected in Serenga delta, (2) morphological and biomolecular study on the genus Eulimnogammarus which has been variously specialized using original and museum specimens, (3) fish groups of the family Cottidae, Abyssocottidae and Comephoridae have been studied from aspects of anatomy, life history and molecular biology using original and museum specimens, (4) pollution study of organochlorine compounds in birds which are migrated into Siberia area from the southern, (5) environmental study on hazerdous chemicals (PCB,DDT,BHC,Hg, Cd, Pb etc.) deposited in Baikal seals, Caspian seals and ringed seals, (6) stable isotope study on ecosystem in Lake Baikal, and (7) morphological and molecular biological study on three species of subgenus Pusa, Phoca sibilica from Lake Bikal, Phoca caspica from Caspian Sea and Phoca hispida from the Arctic Ocean, using original and museum specimens. These results were published as 41original scientific papers, 5 books and 7 documents, and were presented in 44 scientific meetings.
