“…To compare the colonization speeds of the benthic macroinvertebrate communities, we adopted the Shannon diversity index and colonization index (CI). The CI was invented to measure changes in aquatic communities during the early successional phases in wetlands (Kim et al 2014). …”

“…We based our experimental period and conditions on our preceding experiment conducted at the experimental site from May 2009 to October 2010 (Kim et al 2014), which showed that benthic macroinvertebrate communities in newly created wetlands were 90% similar to those in a nearby source wetland within one year. We also adopted our preceding colonization experiment data as reference natural wetland data because the experiment site, period, and procedures are similar to those of newly created mesocosms except for the drought condition.…”

“…We replaced all existing soil with new soil from a seed-free area in order to avoid the seed bank and eggs of macroinvertebrates. During the initial wetland construction, we planted rushes (Juncus effusus) and wild rice (Zizania latifolia) in five pots each (Figure 1(e)) because early planting facilitates benthic macroinvertebrate colonization (Kim et al 2014). We supplied ground water (in order to avoid a direct influx of benthic macroinvertebrates) to maintain a water depth of 30 cm (Figure 1 (d)).…”

“…Generally, the successional process includes initial rapid colonization, followed by a gradual, predictable change in structure and organization of the floral and faunal communities, such as decreases in dominance values and gradual shifts from predators to grazers and detritivores (Kim et al 2014). Furthermore, the species pool, habitat connectivity, primary productivity, and disturbance may affect the successional trajectory (Chase 2003).…”

“…Furthermore, the species pool, habitat connectivity, primary productivity, and disturbance may affect the successional trajectory (Chase 2003). Many studies have evaluated the successional states of benthic macroinvertebrate communities in natural and man-made wetlands and whether human-made communities eventually resemble natural wetland communities (see Table 1 in Kim et al 2014).…”

We investigated the drought effects on the colonization rate and pattern of benthic macroinvertebrate communities in newly created mesocosm wetlands in the central Korean Peninsula, from June 2011 to June 2013. The comparison was made between the initial colonization after mesocosm construction (pre-drought) and the recolonization after a drought event (post-drought) with a drought period of 50 days between them. In addition, we categorized communities according to their biological traits in relation to drought. Our results showed that aquatic vegetation abundance and covering degree were higher in post-drought than in pre-drought, thereby influencing rapid colonization. Drought-resistant benthic macroinvertebrates colonized rapidly in post-drought; consequently, the colonization speed was 2.5-fold higher in postdrought than in pre-drought. We classified the benthic macroinvertebrate taxa into three groups: (1) a resistant group which generally emerged after the initial colonization period (e.g., Mollusca, Turbellaria, and Oligochaeta); (2) a sensitive group with diverse life history strategies and biological traits such as active migration or population decline after drought disturbance (e.g., Diptera: Chironominae, Odonata: Orthetrum, Coleoptera: Agabus and Rhantus); and (3) a seasonal group, which emerged only during certain periods and were not markedly influenced by drought (e.g., Ephemeroptera: Cloeon, Diptera: Culicidae, Odonata: Zygoptera and Pantala). Our findings elucidated the effects of drought on benthic macroinvertebrate communities in wetlands by using a mesocosm experiment.
