Excessively large river estuaries of tropics can be impacted within months by successive tropical cyclones. The effect of these disruptions on the community ecology of such estuaries has been scarcely examined. On a daily basis for a week, the copepod community of the Ganges River estuary of India, was studied immediately after Cyclone Fani and Cyclone Bulbul in May and November 2019, respectively. The objective was to understand the ecological response of the copepod community of the Ganges River estuary facing successive extreme environmnetal changes in short interval. Differences in landfall sites and the amount of rain associated with each tropical cyclone led to different degrees of temporal changes of salinity, pH, and water-temperature of the estuary which might have caused the observed addition-deletion of species, rearrangements of abundance-hierarchy and expansion-shrinkage of omnivore-herbivore feeding guilds of the copepod community. The copepod Bestiolina similis maintained, however, its numerical dominant status. Tropical cyclone driven changes to the copepod community of an estuary may be temporary but the changes may affect benthic-pelagic linkages. Following an extreme environmntal change (e.g. cyclone, flood), an institution-backed monitoring (mix of high to low intensity sampling lasting for a few hours to years) with matching scales of zooplankton and biogeochemical data collection, encompassing freshwater and marine dominated sections of the Ganges River estuary is recommended. Nations bordering the Indian Ocean may consider a similar recommendation for monitoring their estuaries after any extreme environmental change, taking account of locale-specific modifications, and initiate a regional programme of estuaries on the United Nations Decade of Ocean (2020–2030) by collaborating through inter-governmental platforms.

连续几个月的热带气旋会在几个月内影响热带地区太大的河口。几乎没有研究这些破坏对这些河口社区生态的影响。在一周的每日基础上，分别在2019年5月和2019年11月的飓风Fani和飓风Bulbul之后立即研究了印度恒河河口的pe足类动物群落。目的是了解恒河河口co足类群落在短时间内面临连续极端环境变化的生态响应。每个热带气旋的登陆地点和降雨量的差异导致河口盐度，pH和水温随时间变化的程度不同，这可能导致观察到的物种增减，pe足类动物群落的杂食动物-食草动物种群的丰度-层次结构和扩张-收缩的重新排列。pe足类百香果但是，它仍然保持其数字主导地位。热带气旋驱动的河口co足类群落变化可能是暂时的，但这种变化可能会影响底栖-上层的联系。在极端的环境变化（例如飓风，洪水）之后，由机构支持的监测（持续数小时到数年的高强度到低强度采样的混合）的规模与浮游动物和生物地球化学数据收集的规模相匹配，包括淡水和海洋为主的区域推荐恒河河口。与印度洋接壤的国家可能会考虑采取类似的建议，以应对任何极端的环境变化，并考虑到特定地区的变化，以监控其河口，
