ABSTRACT This paper summarises Keith Walker’s contribution to the understanding of aquatic, littoral and floodplain understorey vegetation in inland arid, semi-arid and Mediterranean aquatic ecosystems. The work undertaken by Keith and his Ph.D. students included the vegetation dynamics of lower River Murray weir pools, wetlands and floodplains, Darling River floodplain lakes and adaptations of plants to these environments. Studies showed that hydrology was the primary driver of the vegetation of these systems and changes to hydrology brought about by abstraction and river regulation resulted in changes to floristic composition. The responses and investigations of adaptions of individual species to hydrology in controlled experiments provided information regarding the mechanisms of change brought about by altered hydrology. This information has provided the basis of our understanding of vegetation dynamics in weir pools, fundamentally changed how weirs and storages were operated in the lower River Murray, contributed to guidelines for the management of wetlands with flow control structures and the development of vegetation monitoring programs used to assess the effectiveness of restoration activities.

对了解墨累河下游及其他地区的植物、生态和水文贡献

摘要 本文总结了 Keith Walker 对了解内陆干旱、半干旱和地中海水生生态系统中水生、沿海和洪泛平原下层植被的贡献。基思和他的博士所做的工作。学生包括墨累河下游堰池、湿地和洪泛区、达令河洪泛区湖泊的植被动态以及植物对这些环境的适应性。研究表明，水文是这些系统植被的主要驱动力，取水和河流调节带来的水文变化导致了植物区系组成的变化。在受控实验中对个别物种对水文的适应性的反应和调查提供了有关由改变的水文引起的变化机制的信息。
