“…Mollusk (group SC) dominated at sampling sites of S25 ~ S28 in the downstream of river, which close to oodplain wetlands along Ussuri River. 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].…”

“…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.

“…In estuarine wetlands, benthic invertebrates are directly involved in the material circulation and energy flow of ecosystems, and are sensitive to environmental changes and disturbances. Therefore, they are often used as biological indicator for bioassessments (Guan et al, 2017;Wu et al, 2017Wu et al, , 2019Lu et al, 2019;Guan and Wu, 2021). In recent years, due to the multiple influences of natural factors and human activities, many estuarine wetlands have been degraded, their biodiversity has been diminished, and their ecosystem structure and function have been compromised.…”

In recent years, the relative importance of the processes driving metacommunity composition has aroused extensive attention and become a powerful approach to identify community patterns and their regulatory mechanisms. We investigated variations in the composition of benthic community in restored wetlands and natural wetlands in the Yellow River Delta (Shandong Province, China). First, spatial structures within each wetland were modeled with Moran eigenvector maps. Next, the variation in community structure among local environmental and spatial variables was partitioned using constrained ordination, and the “elements of metacommunity structure” analysis was used to determine the patterns of best fit for species distributions within metacommunities. Finally, the null model was used to analyze non-random patterns of species co-occurrence. The community structure of benthic invertebrates in restored wetlands and natural wetlands differed significantly. The benthic invertebrate metacommunity structure showed a nested distribution in restored wetlands and a quasi-Clementsian structure in natural wetlands. Pure environmental fractions and pure spatial fractions were critical in regulating benthic invertebrate metacommunities of restored wetlands. In natural wetlands, pure spatial fractions and the interaction between environmental and spatial factors (shared fractions) played a major role in the metacommunity. A species co-occurrence analysis showed that species co-occurred more frequently than expected by chance, demonstrating that biotic interactions were not the main driver of metacommunity structures in both wetland types. Accordingly, the benthic invertebrate metacommunity in estuarine wetlands following freshwater releases was mostly determined by environmental and spatial effects, which resulted in a metacommunity with nested distribution. These results are important for biodiversity protection and ecosystem management of estuarine wetlands in the Yellow River Delta.

“…In freshwater ecosystems, hydrological connectivity is known to influence biogeochemical fluxes (Hosen et al 2018;Thom et al 2018), food-web structure (Reid et al 2012), macroinvertebrate assemblages (Reese and Batzer 2007;Leigh and Sheldon 2009;Paillex et al 2009;Guan et al 2017),…”

“…macrophytes (Amoros and Bornette 2002), fish assemblages (Aarts et al 2004;Lasne et al 2007;Fullerton et al 2010), and the zooplankton community (de Paggi and Paggi 2008). Studies from rivers and bodies of water along the alluvial floodplain found that hydrological connectivity strongly influences the macroinvertebrate assemblage composition and diversity (Reese and Batzer 2007;Leigh and Sheldon 2009;Paillex et al 2009;Guan et al 2017). However, the influence of hydrological connectivity on invertebrates has been rarely studied in coastal wetlands.…”

Hydrological connectivity controls the patterns of invertebrate assemblages in wetland ecosystems. With degradation of intertidal wetlands, artificial freshwater release has become an important restoration technique. Hydrological connectivity with tidal creeks is also a key ecological process for intertidal wetlands. However, how hydrologic connectivity affects snail assemblages remains poorly investigated in intertidal wetlands. We studied the differences in snail assemblages in wetlands to understand the effects of hydrological connectivity, wetland to river, and wetland to ocean. We found freshwater connectivity can transform intertidal snail assemblages into freshwater snail assemblages; restored wetlands primarily had freshwater snail species and natural intertidal wetlands mainly supported marine or salt-adapted snail species. Cluster analysis, nMDS plot and ANOSIM analysis showed snail assemblages were influenced strongly by hydrological connectivity. Stenothyra glabra, Oncomelania sp. and Nassarius festivus were indicators of natural intertidal wetlands. Hippeutis cantori, Radix swinhoei and Succinea pfeifferi were indicators of restored wetlands. Our results suggest natural hydrological connectivity with the ocean needs to be maintained when attempting to restore intertidal wetlands. Without this connection, connecting impaired wetlands only to rivers, may not achieve restoration of natural biotic assemblages.
