“…First, niche size was significantly smaller in anthropogenically modified habitats than in natural open waters at both community and population levels, indicating that the overall reduction in food availability and diversity was caused by habitat modification (Li et al., 2020). Further, the significantly higher degree of niche overlap between species with similar trophic niches suggested that the reduced prey availability and diversity in modified habitats (Dong et al., 2021; Li et al., 2021) could prevent the coexisting species to achieve prey partitioning, leading to the declining population and the ultimate exclusion of the disadvantaged one, usually the natives (the Oriental Shrimp in our study system). In conclusion, our results highlight that the competitive outcomes of interspecific trophic interactions can depend on the prey availability and diversity (Costa‐Pereira et al., 2019), which embraces the classic optimal foraging theory and competition theory to understand how environmental change, such as habitat modification and conversion, affects biological invasion processes and biodiversity loss.…”

“…In a previous study of the same system, Dong et al. (2021) found that the hydrological connectivity was dramatically reduced from fully connected in the main river channels and open water habitats to 10% in the plantation, resulting in relatively stable hydrology in the highly modified sites (Li et al., 2021). The elevated nutrient level and stable hydrological condition could promote primary productivity, and this would be expected to favour some guilds of zooplankton (e.g.…”

“…There is broader conceptual and empirical support for determinism having higher relative importance in logged forests, which tend to have harsher environmental conditions compared to primary forests. Harsher environmental conditions can inflict a deterministic filter on community assembly, thus increasing the importance of deterministic processes, which has been demonstrated across a variety of taxa and regions (Chase 2007, Lepori & Malmqvist 2009, Chase & Myers 2011, Ding et al 2012, Wearn et al 2019, Li et al 2021, Hu et al 2022).…”

Understanding how community assembly processes drive biodiversity patterns is a central goal of community ecology. While it is generally accepted that ecological communities are assembled by both stochastic and deterministic processes, quantifying their relative importance remains challenging. Even fewer studies have investigated how the relative importance of stochastic and deterministic community assembly processes vary among taxa and along gradients of habitat degradation. Using data on 1,002 invertebrate species across six taxonomic groups in Malaysian Borneo, we quantified the importance of stochastic and deterministic community assembly processes across a gradient of logging intensity. Dispersal limitation was the dominant process at all levels of logging intensity. The relationship between logging and community assembly varied depending on the specific combination of taxa and stochasticity metric used, but, in general, the processes that govern invertebrate community assembly were remarkably robust to changes in land use intensity.

“…Moreover, water quality and other ecosystem components (e.g., fish communities and extent of submerged aquatic vegetation) within these artificial lakes are affected by shifts in the environmental conditions of the rivers that feed them (Cai et al, 2019). There has been extensive research aimed toward developing restoration strategies for maintaining ecosystem function in natural lakes within the MLYRB [e.g., Taihu Lake (Wang et al, 2019) and Dongting Lake (Li B. et al, 2021)]. However, maintaining proper ecosystem function and identifying effective restoration strategies for artificial water supply lakes is much less common, despite their importance for protecting human health in the EPC.…”

With the intensification of eutrophication, many artificial water supply lakes that act as a biological filter for water diverted from rivers have been built to alleviate water scarcity in Eastern China. In this study, we selected Lake Yanlong, a representative artificial water supply lake in Yancheng City, as our experimental lake to explore how the community composition of fishes changed among different habitat types and assess potential consequences for effective water treatment. From October 2015 to October 2020, we conducted quarterly surveys of fish communities and environmental factors in the Mangshe River (MR; water for lake) compared to four different water treatment zones of Lake Yanlong (PZ, the pretreatment zone with inlet from the MR; EZ, the emergent macrophyte zone; SZ, the submerged macrophyte zone; DZ, the deep purification zone with outlet to urban waterworks). A total of 16,339 individual fish belonging to 11 families and 49 species were collected. Six of the eight dominant species observed across zones were small-bodied fishes. Despite reduced fish species richness, the relative abundance and biomass of fishes tended to be higher in Lake Yanlong relative to the MR. The Shannon-Wiener diversity index, Pielou evenness index, Simpson’s diversity index all decreased from the MR to the DZ in the following sequence: MR < PZ < EZ < SZ < DZ. Analysis of similarities and similarity percentage analysis confirmed that fish communities differed significantly among zones and Coilia ectenes, Carassius auratus, Pseudobrama simony, Hemiculter leucisculus, and Hemiculter bleekeri were the major differentiating species. Mantel’s test and redundancy analysis revealed that water depth, aquatic vegetation coverage, and phytoplankton concentrations were the major factors determining the spatial distribution of fishes when moving from the MR to the DZ of Lake Yanlong. Stocking piscivorous fish can be used as an effective measure to control the abundance of prolific small-bodied fishes in Lake Yanlong. The details backing these findings are important for understanding how the community composition of fishes among habitat types in Lake Yanlong influence water quality, and to develop suitable biomanipulation strategies for the management of fish resources and maintaining proper function of these artificial water supply lakes.
