“…The generally longer hydroperiods and more even distribution of aquatic vegetation in the natural wetlands and in more mature restoration sites likely favored invertebrate colonization. This phenomenon has been observed in other wetland studies (Wu et al 2017; Lu et al 2019). Groups that do not readily reestablish probably are limited by a biotic filter (Meyer & Whiles 2008) associated with the lack of aerial dispersal capabilities.…”

Wetland restoration has been implemented widely but evaluation of the effectiveness of wetland restoration has been limited. In this study, we aimed to investigate the utility of aquatic invertebrate assemblages as potential indicators of restoration condition in wetlands of the Sanjiang Plain, Northeastern China. Results from non‐metric multidimensional scaling analysis of invertebrate assemblages showed that study wetlands (n = 16) divided into two groups: natural wetlands and wetlands that have been restored for 4 years were classified as a group, and impaired wetlands and wetlands restored for only 1 year were classified into another group. After 4 years of recovery, 47.9% of invertebrate taxa found at the natural wetlands could also be found at the restored wetlands, primarily insects with aerial dispersal capabilities for rapid colonization. Indicator species analysis identified differences in community composition among wetland types, and Amphiagrion sp. and Bezzia sp. were indicators of the restored wetlands. In Northeastern China, aquatic invertebrate assemblages and certain indicator species may provide robust measures of wetland restoration. It is urgent for further exploration to monitor restored wetlands in the long‐time series and fully assess the efficiency of the restoration.

“…The mean annual precipitation is 550 mm, more than 60% of which falls between July and September. The mean altitude of the study area is 55 m. Freshwater sedge marsh is the major type of original natural wetlands in the Sanjiang Plain (Wu et al 2010; Wu et al 2017).…”

“…Guan et al (2017) sampled macroinvertebrate assemblages along Wusuli River (upstream, midstream, and downstream), and agreed with the emerging theory suggesting that aquatic invertebrate assemblages in oodplain wetlands should change longitudinally along a river's length and be affected by lateral connectivity of oodplain habitats with main river channels [31]. Wu et al (2017) found that snails could be possess several attributes that should make them useful as potential environmental indicators in Sanjiang Plain, and the certain snail species may provide a robust and rapid indicator of environmental impacts in freshwater in Heilongjiang Province of China [32]. Next year, Guan et al (2018) also con rmed that the snails (Mollusca:…”

“…We guessing that heavy metal ion may contribute to primary productivity and indirectly affects secondary productivity by food chains in the aquatic ecosystems. Besides, hydrology is considered the paramount environmental control of freshwater wetlands, with temporary drying being a major constraint on aquatic insects [31][32][33]41]. The movement group [7] of macroinvertebrates could be considered as a new method for monitoring and evaluating water quality in Muling River basin for further studies in the future.…”

Background: Muling River is the ﬁfth-largest river in Heilongjiang Province, and it is also the main feeding river to the Ussuri River which is the boundary river of China and Russia in Heilongjiang Province northeast of China. Muling River basin located in the south of Sanjiang Plain. Macroinvertebrate samples were collected using a D-frame net and Shannon-Wiener index were calculated in terms of abundance. Results: A total of 158 genera or species macroinvertebrate were collected from the 28 sampling sites and classified into six functional feeding groups including 61 gatherers/collectors, 42 predators, 22 scrapers, 14 shredders, 11 filterers/collectors and 8 omnivores. The correlation and relationship between environmental variables and macroinvertebrate functional feeding groups was explored using Pearson analysis and redundancy analysis. The analysis results displayed that macroinvertebrate functional feeding groups had strong relationships with the environmental variables in the Muling River basin.Conclusions: All FFGs, total abundance and Shannon-Wiener index were not significantly different. Total abundance of macroinvertebrates was higher in summer and biodiversity index was higher in autumn. Environmental factors of natural gradients and nutrition indicator were not significantly different, while others were significantly different.

“…Total number of taxa is common metric shaping MMIs globally (Baptista et al, 2007;Couceiro et al, 2012;Lu et al, 2019), demonstrating its capability to respond to diverse ecological alterations. Snails (Mollusca: Gastropoda) are widely distributed in freshwater wetlands and are good indicator of environmental conditions in other Chinese wetlands (Wu et al, 2017;Lu et al, 2019).…”

Adjacent intensive agriculture disturbs the natural condition of wetlands. However, to assess the effect of this agriculture on wetlands, few studies have used indices based on aquatic invertebrates. Multi-metric indices (MMIs) have been successfully used to assess freshwater ecosystems worldwide and are an important management tool, but little is known about their applicability in the Sanjiang Plain, Northeast China. In this study, we developed a MMIs for aquatic invertebrates to assess freshwater wetlands in this region. The aquatic invertebrate assemblages were sampled in 27 wetlands in the Sanjiang Plain that included those in natural reserves and those affected by adjacent, intensive agriculture. Twenty-four candidate metrics were initially reviewed and screened before four core metrics were selected: total number of taxa, number of Hemiptera taxa, proportion of Gastropoda, and proportion of predators. Mann-Whitney U tests, Box and Whisker plots, correlation analyses, and redundant metric tests were used to assess the ability of metrics to distinguish among reference and impaired wetlands. Four ordinal rating categories for wetland were defined: poor, fair, good, and excellent. Of the impaired freshwater wetlands, 76.2% were in poor or fair categories. The MMIs was robust in discriminating reference wetlands from impaired wetlands and therefore have potential as a biomonitoring tool to assess the condition and to guide the restoration efforts of freshwater wetlands in Northeast China.
