Freshwater lakes are subjected to increasing eutrophication and algal blooms worldwide, which have dramatically impacted the aquatic biodiversity. This situation is especially true in the Yangtze River Floodplain, China. However, few researches have been focused on differences in the spatial and temporal patterns of benthic macroinvertebrates assemblages between the two adjacent lakes in this floodplain. In this study, we conducted seasonal investigations in 2021 to compare the spatial and temporal patterns of macroinvertebrates in Lakes Taihu and Lake Chaohu. Non-metric multidimensional scaling (NMDS) analyses showed Lake Taihu was found to have differences in assemblages within the lake, but Lake Chaohu was found to have uniform assemblage across the entire lake. Macrophyte-dominated lake regions (eastern Lake Taihu) were characterised by the highest species richness and diversity indices than those in other lake regions. The pollution sensitive species (e.g. EPT: Ephemeroptera, Plecoptera and Trichoptera) were only distributed in the macrophytic areas of Lake Taihu. Corbicula fluminea, polychaetes Nephtys oligobranchia and Capitella sp. were dominant in the middle central lake regions in Lake Taihu. Lake Chaohu and the northern Lake Taihu, with turbid algal-dominated state, were characterised by dominance of Oligochaetes and Chironomids. These differences were attributed to varying habitats and environmental parameters among different lake regions. Canonical correspondence analysis (CCA) demonstrated that macrophytes, chemical oxygen demand (CODMn), temperature, ammonium (NH3-N) and electric conductivity (EC) were detected as important factors influencing such macroinvertebrate assemblage patterns between these two lakes. This study contributes to the scientific knowledge of within lake habitats, community assemblages, nutrients and pollution within these lakes.

This paper introduces a normative, expert-informed, time-dependent index of Social Inclusion for European administrative regions in five countries, using longitudinal data from Eurostat. Our contribution is twofold: first, our indicator is based on a non-additive aggregation operator (the Choquet Integral), which allows us to model many preferences' structures and to overcome the limitations embedded in other approaches. Second, we elicit the parameters of the aggregation operator from an expert panel of Italian policymakers in Social Policy, and Economics scholars. Our results highlight that Mediterranean countries exhibit lower Inclusion levels than Northern/Central countries, and that this disparity has grown in the last decade. Our results complement and partially challenge existing evidence from data-driven aggregation methods.

Climate change and human activities have altered the water environment and affected the community structure of aquatic organisms. Few studies have focused on the specific responses of multiple aquatic organisms, and their interactions, to environmental factors, particularly in urban wetland ecosystems. To address this gap, this study aimed to investigate the effects of seasonal variation and water connectivity on water properties and aquatic organisms in the Xixi wetland in Zhejiang Province, China. The results demonstrated that water properties showed significant differences with changes in the season and water connectivity, and the species richness, Shannon-Wiener index, Simpson diversity and Pielou evenness of aquatic organisms varied seasonally in riverways and ponds. Meanwhile, the response of various organisms to environmental factors was inconsistent. Dissolved oxygen and suspended solids greatly influenced phytoplankton, while water temperature was the principal factor affecting the diversity of zooplankton and benthic organisms. The partial least squares path model revealed that water properties had a significant direct positive effect on the diversity of the phytoplankton community, while it had a distinct direct negative effect on zooplankton community. Environmental factors influenced the diversity of benthic organisms through a trade-off way: directly through a significant negative effect on the benthic organisms, and through a significant positive effect on the phytoplankton, further influencing the benthic community in a significantly positive way. This study highlights the understanding of the patterns and underlying mechanisms of freshwater aquatic biodiversity, and the interaction of phytoplankton, zooplankton and benthic organisms to water environmental factors in freshwater ecosystems.
