【学术报道】中国科学院动物研究所魏辅文院士、中国科学院昆明动物研究所施鹏研究员莅临我校进行学术交流

2018年11月27日,应5197. com新浦京生命科学学院杨光教授邀请,中国科学院院士、中国科学院动物研究所魏辅文研究员,以及中国科学院昆明动物研究所施鹏研究员来我校开展学术交流。是日下午2:30,魏辅文院士在生科院三楼圆形报告厅开展了题为“科学构建国家公园的思考——寻找保护与发展平衡的自然比例(N%)”的学术报告;接着,施鹏研究员以“动物回声定位的进化与遗传机制”为题的学术报告。来自相关领域的教师、研究生以及本科生等100多人聆听了此次学术报告会。

在报告中,魏院士首先为大家先容了全球和国内物种濒危状况,强调了物种多样性状况正在面临的严峻挑战;结合人类发展史,从史前文明、农业文明、工业文明延伸至“以人地关系和谐为主旨、以可持续发展为依据”的生态文明。接下来,魏院士以大家耳熟能详的大熊猫保护为例,先容其保护现状及其生态系统服务价值,强调了自然保护地是包括人类在内的生物生存繁衍的基础。进而提出“大家需要多少自然保护地”的问题,引出保护与发展平衡的自然比例——“N%”理念。魏院士指出,充分运用保护生物学、哲学、社会学、经济学等跨学科理论和方法,将是未来中国和全球生态保护的趋势,也会推进具有全球意义的生态环境保护。

施鹏研究员的报告围绕“回声定位”展开,从唯一具有飞行能力的哺乳动物——蝙蝠说起,在宏观上探讨了恒频回声定位蝙蝠独特的内耳发育模式。微观上,首先先容了与高频听力有关的内耳马达蛋白prestin,深入浅出地阐述了其在回声定位物种中的分子机制。以prestin基因为线索,施鹏研究员详细先容了回声定位能力在鲸类中的起源。接着从回声定位蝙蝠内耳毛细胞进化出的独特保护机制、猪尾鼠的回声定位声学特征等多个角度详细阐述了回声定位的进化与遗传机制,向大家呈现了回声定位行为在多种回声定位动物中的起源。

报告结束后,现场讨论气氛热烈,魏辅文院士、施鹏研究员与参会老师和学生进行了深入的学术交流和探讨,就老师、同学们提出的问题做了详细的解答。两位学者渊博的学识、敏捷的思维、缜密的逻辑使我院师生受益匪浅。  

On November 27, 2018, at the invitation of Prof. Guang Yang, College of Life Sciences, Nanjing Normal University (NNU), academician of the Chinese Academy of Sciences (CAS), Prof. Fuwen Wei, from the Institute of Zoology, CAS, as well as Prof. Peng Shi from Kunming Institute of Zoology, CAS, came to our university for academic exchanges. At 2:30 p.m. on the third floor of the College of Life Sciences, Academician Fuwen Wei carried out an academic report entitled "Thoughts on the Scientific Construction of National Parks - Finding the Natural Proportion of Protection and Development Balance (N%)"; and then, the academic report entitled "Evolution and Genetic Mechanisms of Animal Echolocation" was presented by Prof. Shi Peng. More than 100 teachers, graduate students and undergraduates from related fields attended the symposium.

In the report, Academician Wei first introduced the global and domestic endangered status of species survival, emphasizing the serious challenges facing the status of species diversity; combined with the history of human development, from prehistoric civilization, agricultural civilization, industrial civilization to the ecological civilization, which characterized as ”harmony of human-land relationships and Sustainable development”. Next, Academician Wei took panda conservation as an example, introduced its protection status and ecosystem service value, and emphasized that natural conservation sites are the basis of biological survival and reproduction, including human beings. Then it raises the question of "how many nature reserves do we need", and leads to the concept of "N%", which is the natural proportion of the balance between protection and development. Academician Wei pointed out that the full use of conservation biology, philosophy, sociology, economics and other interdisciplinary theories and methods will be the future trend of ecological protection in China and the world, and will also promote the protection of ecological environment with global significance.

Prof. Shi Peng presented a report focuses on "echolocation", starting with studies on bats, the only mammal with flying ability, and explores the unique inner ear development pattern of bats with constant frequency echolocation. Microscopically, prestin, an inner ear motor protein related to high frequency hearing, is first introduced, and its molecular mechanism in species with echolocation is elucidated. Based on the prestin gene, the origin of echolocation in cetaceans was described in detail by Shi Peng. Then, the evolutionary and genetic mechanisms of echolocation are elaborated from the unique protective mechanism evolved from the inner ear hair cells of echolocation bats and the acoustic characteristics of echolocation in chapa pygmy dormouse. The origin of echolocation behavior in various echolocation animals is presented to us.

At the end of the report, there was a warm atmosphere for discussion. Academician Wei Fu Wen and Prof. Shi Peng had in-depth academic exchanges and discussions with participating teachers and students, and gave detailed answers to the questions raised by teachers and students. The profound knowledge, agile thinking and careful logic presented by the two researchers have greatly benefited our teachers and students.
