The COVID-19 pandemic led to an immediate lockdown declared by the government of India (March to April 2020) which saw a decrease in public activities. In view of this, a comparative study was carried out on the influence of environmental parameters on methane activities between the pre-lockdown and lockdown periods along a tropical estuarine mangrove ecosystem. Significant changes in the studied parameters specially in the organic matter and methane production rates (P < 0.05) were observed. During the lockdown as compared to the pre-lockdown period, the downstream site was impacted more than those at the upstream site with an average methane production decrease by 60X and 1.5X respectively. Both, oxidation and production of methane decreased during the lockdown and was related to organic matter availability (P < 0.05). The findings elucidate the positive impact of lockdown on the model ecosystem and the reduction in greenhouse methane activities.

COVID-19 封锁对热带河口红树林生态系统中甲烷相关活动的影响

COVID-19 大流行导致印度政府立即宣布封锁（2020 年 3 月至 4 月），公共活动减少。鉴于此，针对热带河口红树林生态系统封城前和封城期间环境参数对甲烷活动的影响进行了对比研究。 观察到研究参数的显着变化，特别是有机质和甲烷生产率（P < 0.05）。与封锁前相比，封锁期间下游场地受到的影响大于上游场地，平均甲烷产量分别减少了 60 倍和 1.5 倍。封锁期间甲烷的氧化和产生均减少，并且与有机物的可用性相关（P  < 0.05）。研究结果阐明了封锁对模型生态系统和温室气体活动减少的积极影响。
