“…However, as water levels continue to fluctuate in the future, IBI metrics should continue to be periodically re-evaluated to ensure their continued accuracy. Year-to-year changes in water levels have been shown to affect vegetation, invertebrate, and fish communities in these habitats (Gathman et al 2005 ; Gathman and Burton 2011 ; Cooper et al 2014 ; Langer et al 2018 ). Other potential sources of inter-annual variation in fish communities such as shifting seasonal temperatures or changes in wave energy and currents along Great Lakes shorelines may also necessitate periodic re-evaluation of IBI metrics.…”

Biotic indicators are useful for assessing ecosystem health because the structure of resident communities generally reflects abiotic conditions integrated over time. We used fish data collected over 5 years for 470 Great Lakes coastal wetlands to develop multi-metric indices of biotic integrity (IBI). Sampling and IBI development were stratified by vegetation type within each wetland to account for differences in physical habitat. Metrics were evaluated against numerous indices of anthropogenic disturbance derived from water quality and surrounding land-cover variables. Separate datasets were used for IBI development and testing. IBIs were composed of 10–11 metrics for each of four vegetation types (bulrush, cattail, water lily, and submersed aquatic vegetation). Scores of all IBIs correlated well with disturbance indices using the development data, and the accuracy of our IBIs was validated using the testing data. Our fish IBIs can be used to prioritize wetland protection and restoration efforts across the Great Lakes basin. The IBIs will also be useful in monitoring programs mandated by the Agreement between Canada and the United States of America on Great Lakes Water Quality, such as for assessing Beneficial Use Impairments (BUIs) in Great Lakes Areas of Concern, and in other ecosystem management programs in Canada and the USA.

“…Temporal changes in hydrological regimes can affect the dispersal processes of fish (Kushlan, 1976; Langer et al, 2018). In order to verify whether the dispersal processes of fish were affected by hydrological changes in the present study, we tested whether the water temperature and level were related to the numbers of fish that migrated into the channel using the Pearson correlation coefficient.…”

Lateral hydrological connectivity (LHC) maintains the high biodiversity and ecosystem functions in the river–floodplain system. We investigated the changes in the taxonomic and functional composition of fish assemblages in the lateral connection channel between the Yangtze River and Poyang Lake, China, during the dry and wet seasons and which factors drive the changes. The results indicated more lake‐residence species and fewer river–lake species in the channel during the wet season than the dry season, leading to significant seasonal differences in taxonomic compositions and trait patterns. Water temperature, water level and fish migration influenced fish assemblage structures in the channel. Water‐level fluctuations that limited food sources and suitable habitats promoted the migration of riverine and lake‐residence fish during both seasons. Water temperature and level also significantly influenced species‐specific migration. Water temperature influenced the spawning migration of river–lake fish during the wet season. Based on these results, we found temporal species‐specific migration dynamics in fish assemblages in the lateral channel that were related to species’ life‐history traits. Therefore, we inferred that the temporal–spatial interaction of the fish community in the river–floodplain system is essentially derived from the evolutionary adaption to the monsoon climate. This process is well studied and predictable, and can be beneficial for managing the river–floodplain systems. The invasion risk of the exotic species, including fish and macroinvertebrates, should be assessed before implementing LHC restoration.

“…In these cases, environmental flow assessment is based on that the ecosystem has adapted to the natural hydrological situation. Maintaining the natural hydrological situation can effectively maintain the system without steady‐state transition (Langer et al, 2018; X. Q. Liu et al, 2017). However, these studies have not considered lake‐marsh systems with reverse seasonal hydrological patterns (i.e., high water level in winter and low water level in summer).…”

Environmental flow (e-flow) assessment is essential for the ecological protection and restoration of lake-marsh systems. Previous studies on e-flow assessment for lakemarsh systems focused on lake-marsh systems with natural seasonal hydrological patterns (i.e., low water level in winter and high water level in summer). However, they have not considered lake-marsh systems with reverse seasonal hydrological patterns (i.e., high water level in winter and low water level in summer). The reverse seasonal hydrological patterns impose seriously negative impacts on waterbirds, because the hydrological patterns could lead to limited plant germination in spring and massive plant death in summer, leaving few plants available as food for waterbirds in winter, and could consequently reduce the sheltering and forageable areas for waterbirds. This study took Hongze Lake Wetland National Nature Reserve in China as the study area. Based on the habitat requirements of waterbirds, the sheltering and forageable areas for waterbirds under different water-depth and aquatic plant distribution scenarios were calculated. By exploring the impacts of reverse seasonal hydrological processes on waterbird habitats, we determined the necessary e-flows for lake-marsh systems with reverse seasonal hydrological patterns to meet the needs of waterbird habitat. The results showed that the water level of Hongze Lake should be controlled to 13.0-13.1 m in March, 12.5-12.6 m in July, and 12.9-13.0 m in October, which can meet the needs of waterbirds for both shelter and foraging.
