我们研究了台风袭击和农业废水对日本冲绳石垣岛名古拉泻湖红树林河口底栖动物群落的多重影响。在台风来袭前后，比较了受废水影响和未受影响的参考点(嵌套在被树冠覆盖的森林和边缘泥滩中)的环境参数和底栖大型动物群落结构。大多数物理化学因子不受废水负荷、台风袭击或生境差异的影响，但有机参数(食物资源环境)发生了变化；废水输入增加了微型底栖动物和红树林凋落物的数量，而台风袭击显著增加了浮游植物的生物量。污水还增加了底栖大型动物的数量和物种丰富度；然而，台风袭击并没有引起这种变化。在参照点，物种组成明显地分为台风前和台风后，但在废水点处，无论台风是什么，都被归类为同一类群。台风引起的组成变化是由于易受伤害的乔木物种被移走和兼性的机会性物种补充造成的。然而，造成有机丰富条件的废水将通过增强偏爱和容忍富营养条件的物种的优势来锁定这种群落动态。总体而言，人为废水对红树林河口底栖动物群落的影响可能超过自然台风干扰的影响。
We examined the multiple effects of a typhoon strike and agricultural wastewater effluent on benthic faunal communities at the mangrove estuary in Nagura Lagoon, Ishigaki Island, Okinawa, Japan. Environmental parameters and benthic macrofaunal community structures were compared at wastewater-impacted and intact reference sites (which were nested in canopy-covered forests and fringing mudflats), before and after the typhoon strike. Most physical and chemical factors were not affected by wastewater loading, typhoon strikes, or habitat differences; however, organic parameters (food resource environment) were changed; wastewater input raised amounts of microphytobenthos and mangrove litter, while a typhoon strike significantly increased phytoplankton biomass. Wastewater effluent also increased the numerical abundance and species richness of benthic macrofauna; however, a typhoon strike did not induce such changes. Species compositions were clearly divided into pre-and post-typhoon periods at the reference site, but were classified into the same cluster at the wastewater site, regardless of the typhoon. The typhoon-induced compositional shift is caused by the removal of vulnerable arboreal species and facultative opportunistic species recruitment. However, wastewater that causes organic-rich conditions would lock such community dynamics by enhancing the predominance of species that prefer and tolerate eutrophic conditions. Overall, the impact of anthropogenic wastewater could outweigh those of natural typhoon disturbances on benthic faunal communities in mangrove estuaries.
