Aftereffects of the attack of the Hurricane Katrina to wetland forests consist mainly of Taxodium distichum and Nyssa aquatica in the Mississippi floodplain were studied spatiotemporally, ecologically and physiologically. In damaged forest stands a rapid increase in number of invasive woody species such as Triadica sebifera and Melia azedarach occurred. Various physiological analyses including growth and photosynthetic rates, ion distribution in organs and osmolite accumulation in leaves were performed to compare flooding and salinity stress tolerance among those native and invasive species. It is concluded that invasive T. sebifera species has high tolerance to flooding and salinity environment as much as that of native species, suggesting the the possibility of rapid expansion of this species in the Mississippi floodplain after occurrences of large-scale disturbances.

卡特里娜飓风对湿地森林的攻击的后果主要由密西西比州洪泛区中的分型distichum和Nyssa aquatica组成，并在生态和生理上进行了空间。在受损的森林中，发生了侵入性木质物种（例如Triadica Sebifera和Melia Azedarach）的数量迅速增加。进行了各种生理分析，包括生长和光合速率，器官和叶片在叶片积累中的离子分布进行比较，以比较那些本地和入侵物种的洪水和盐度胁迫耐受性。结论是，侵入性的塞比弗拉物种与本地物种一样，对洪水和盐度环境具有很高的耐受性，这表明在发生大规模干扰后，在密西西比州洪泛区中这种物种快速扩张的可能性。
