Biodiversity, Phylogeny and Environment in Lake Baikal

“贝加尔湖生物多样性、系统发育和环境”研究由14名日本科学家和12名外国科学家在以下5个研究项目中完成：(1)贝加尔湖淡水海绵的分类学和生态学研究；(2)片足类的形态学和生物分子研究；(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等方面对cotitidae、abyssocotitidae和comphoridae的鱼类类群进行了研究；(4)对来自贝加尔湖的Pusa亚属Phoca sibilica 3种进行了形态学和分子生物学研究；(5)贝加尔湖及邻近水域有害化学物质（多氯联苯、滴滴涕、六六六、汞、镉、铅等）的环境研究。这些结果以17篇原创科学论文、5本书和10篇文献的形式发表，并在59次科学会议上发表。1998年11月8日至10日，来自8个国家的50名科学家参加了在箱根举行的“贝加尔湖生物多样性、系统发育与环境”国际研讨会，交流了贝加尔湖的最新情况。

The study "Biodiversity, Phylogeny arid Environment in Lake Baikal" was made in the following 5 research items by 14 Japanese scientists and 12 foreign scientists ; (1) taxonomical and ecological study on freshwater sponges collected in Lake Baikal, (2) morphological arid biomolecular study on amphipoda, (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) morphological and molecular biological study on three species of subgenus Pusa, Phoca sibilica from Lake Baikal, Phoca caspica from Caspian Sea and Phoca hispida from the Arctic Ocean, using original and museum specimens, and (5) environmental study on hazerdous chemicals (PCB, DDT, BHC, Hg, Cd, Pb, etc.) deposited in Lake Baikal and adjacent waters. These results were published as 17 original scientific papers, 5 books and 10 documents, and were presented in 59 scientific meetings. Fifty scientists from 8 countries participated in the International Symposium on Lake Baikal : "Biodiversity, Phylogeny and Environment in Lake Baikal" held at Hakone during 8-10 November 1998, and exchanged the advanced information on Lake Baikal.
