气候变化对海洋病毒生态特性及其生物地球化学效应的影响

Effects of global climate change on the ecological characteristics and biogeochemical significance of marine viruses-A review

摘要:

摘要:病毒作为海洋中丰度最高的生命粒子，通过侵染和裂解宿主细胞影响宿主生理生态特性，改变海洋食物网的物质循环和能量流动，在海洋生物地球化学过程中扮演着重要角色。全球气候变化导致海面升温、海洋酸化、营养盐和海水盐度变化、低氧区扩大等海洋环境问题，对海洋病毒生理生态特性产生直接或间接的影响。本文从海洋病毒的生态功能和生物地球化学效应出发，概述了气候变化因子对病毒分布、丰度、生命策略以及与宿主之间相互作用等的影响，提出海洋病毒是全球气候变化研究中不可或缺的对象。

Abstract:

Abstract:As the most abundance biological agents in the oceans，viruses can influence the physiological and ecological characteristics of host cells through viral infections and lysis，and affect the nutrient and energy cycles of the marine food chain． Thus，they are the major players in the ocean biogeochemical processes． The problems caused by global climate changes，such as sea-surface warming，acidification，nutrients availability，and deoxygenation，have the potential effects on marine viruses and subsequently their ecological and biogeochemical function in the ocean． Here，we reviewed the potential impacts of global climate change on the ecological characteristics (e. g．abundance，distribution，life cycle and the host-virus interactions) and biogeochemical significance (e．g．carbon cycling) of marine viruses．We proposed that marine viruses should not be ignored in the global climate change study.
