4月27日，南海海洋资源利用国家重点实验室第三十二期午餐交流会于国重823室举行。本次午餐会以“海洋鱼类功能性状和功能多样性”为主题，由罗洪添副研究员主持，副研究员陈凯主讲。陈凯副研究员从海洋鱼类主要栖息地、海洋鱼类多样性危机、海洋鱼类多样性的价值、海洋鱼类功能性状和多样性对环境胁迫的响应等角度作分享与交流。

On April 27, the 32nd luncheon seminar was held in MRU Conference Room 823. With the theme of “Functional Traits and Functional Diversity of Marine Fishes”, the seminar whose presenter was Associate Research Professor Chen Kai was hosted by Associate Research Professor Luo Hongtian. Chen shared his views on the main habitats of marine fishes, the crisis of marine fish diversity, the value of marine fish diversity and the response of functional traits and functional diversity of marine fishes to the environmental stress.

陈凯指出，海洋鱼类多样性作为自然资源的重要组成部分，在全球粮食安全、经济和社会发展、生态系统稳定等方面发挥着至关重要的作用。然而在全球变化和人类活动的影响下，海洋鱼类多样性正以前所未有的速度退化或丧失；海洋鱼类面临巨大威胁的原因在于日趋严重的过度捕捞、气候变化和栖息地退化等压力。如何准确评估鱼类种群和群落对环境胁迫的响应与鱼类群落结构和功能的变化对生态系统功能的影响是海洋鱼类多样性和海洋生态系统保护的关键科学问题。陈凯谈到，海洋鱼类功能生态学的发展是解答这一问题的重要框架之一。开展海洋鱼类功能性状和功能多样性等功能生态学研究，不仅有助于更好地应对全球变化情景下生物多样性丧失的生态学后果，而且能为生态恢复实践提供理论基础。

As an important component of natural resources, marine fish diversity played a vital role in global food security, economic and social development, and ecosystem stability, according to Chen. However, under the influence of global climate change and human activities, marine fish diversity was degraded or lost at an unprecedented rate, and marine fish were facing great threats due to the overfishing, climate change and habitat degradation. Therefore, how to accurately assess the response of fish populations and communities to environmental stress and the impact of changes in fish community structure and function on ecosystem functions were key scientific questions for preserving marine fish diversity and marine ecosystem. Chen mentioned that the development of marine fish functional ecology was one of the keys to answering this question, and conducting functional ecology studies on such topics as functional traits and functional diversity of marine fishes would not only help to better cope with the ecological consequences of biodiversity loss under the scenario of global climate change, but also provide a theoretical basis for ecological restoration practices.
