The inhibitory effects of ulvoid algae and their seasonality on the recovery and succession of an intertidal algal community were investigated under field conditions using a two‐factorial design. The experiment was conducted in the mid‐low intertidal zone on the Southern coast of Korea. In spring and fall, each of the ten 50 × 50 cm plots was disturbed artificially, and Ulva spp. were continuously excluded from five plots of the seasonal plots. The succession of spring plots was nearly twice as fast as that of the fall plots (spring, 4–6 months; fall, 10–15 months), indicating that the seasonal effects contributed significantly to the speed of the succession. The inhibition by Ulva species delayed the succession; however, the strength of this delay was limited largely by the duration and persistence of Ulva mass, which was also highly seasonal. The presence of Ulva spp. did not alter the final assemblage at the climax stage; instead, it caused a delay in community resilience. This study provides a few analytical factors for community‐wise comparison during the evaluation of the status of successional stages.

石莼属的影响。温带岩石潮间带群落恢复的季节性干扰

在田间条件下，使用双因素设计研究了超大藻及其季节性对潮间带藻类群落恢复和演替的抑制作用。试验在韩国南部沿海中低潮间带进行。在春季和秋季，10 个 50 × 50 cm 地块中的每一个都受到了人工干扰，石莼属。连续被排除在季节性地块的五个地块之外。春季地块的演替速度几乎是秋季地块的两倍（春季，4-6 个月；秋季，10-15 个月），表明季节效应对演替速度有显着影响。石莼物种的抑制延迟了演替；然而，这种延迟的强度在很大程度上受到石莼肿块的持续时间和持久性的限制，这也是高度季节性的。石莼属的存在。没有改变高潮阶段的最终组合；相反，它导致了社区复原力的延迟。本研究为评估演替阶段状态期间的社区比较提供了一些分析因素。
