With the acceleration of urbanization, biodiversity and ecosystem functions urban wetlands are facing serious challenges. The loss aquatic plants in is becoming more frequent intense due to human activities; nevertheless, effects on wetland ecosystems have received less attention. Therefore, we conducted field investigations across 10 Jinan, Shandong Province, as a case North China examine relationships between plant coverage phytoplankton diversity, well resource use efficiency (RUE) wetlands. Multivariate regression partial least squares structural equation modeling (PLS-SEM) were used analyze water quality, RUE. results demonstrate that increase significantly reduced concentration total nitrogen suspended solids’ concentrations increased diversity (e.g., species richness functional diversity). affected composition groups; for example, groups had adapted still-water low-light conditions became dominant. Furthermore, improved RUE, highlighting importance maintaining functions. This study may provide scientific basis management strategy wetlands, emphasizing key role appropriate cover ecological stability service

Freshwater biodiversity has been declining in urban areas, which may threaten ecosystem functions. Although many studies have demonstrated a positive correlation between and functioning (BEF) terrestrial marine ecosystems, little is known about the BEF relationship freshwater environments, especially highly urbanized regions where water pollution major concern. Eutrophication bodies trigger algae blooms, decreasing evenness or functional divergence (FDiv) of phytoplankton communities, thus negatively affecting functioning. Through an annual field investigation, we clarified diversity functioning, represented as resource use efficiency (RUE), river northern China. Results indicated that community contributes most to driving compared environmental factors. The relative abundance dominant Bacillariophyta was positively correlated with (RUEpp) but zooplankton (RUEzp). Both were linked RUEpp RUEzp. Our findings suggest reduction seriously its potential mechanism can provide crucial reference for quality protection sustainable utilization basin.

The unprecedented urbanization recently has inevitably intensified the changes in land use morphology. However, current studies on primarily analyze a single morphology, ignoring relationships between different morphologies. Taking northern slope of Tianshan Mountains (NSTM) as study area, this article quantifies spatiotemporal pattern change, and estimates trade-offs synergies dominant (patch density, largest patch index, landscape shape index) recessive (land efficiency, intensity, agricultural non-point source pollution) morphologies to fully understand dynamic characteristics use. Results showed bare areas grassland were always predominant types, change from 1990 2020 was characterized by increase impervious surfaces decrease areas. strongest trade-off found index while synergy intensity strongest. There are significant disparities terms temporal spatial patterns trade-offs/synergies. correlation coefficients periods much smaller than their estimations whole region, trade-offs/synergies eastern NSTM basically identical with relationships. findings reveal interactions among various characteristics, provide references for coordinated management regional high-quality development.

An ecosystem shifts to an alternative stable state when a threshold of accumulated pressure (i.e. direct impact environmental change or human activities) is exceeded. Detecting this in empirical data remains challenge because ecosystems are governed by complex interlinkages and feedback loops between their components pressures. In addition, multiple mechanisms exist that can make resilient shifts. Therefore, unless broad ecological perspective used detect shifts, it questionable what extent current detection methods really capture whether inferences made from smaller scale analyses be implemented into management. We reviewed the techniques currently for retrospective data. show most not suitable taking approximately 85% do combine intervariable non-linear relationships high-dimensional variables, but rather tend focus on one subsystem ecosystem. Thus, our perception may limited often sets, unrepresentative whole ecosystems. By reviewing characteristics, advantages, limitations techniques, we identify provide potential incorporate ecosystem-based approach. therefore perspectives developing better suited detecting interactions high-dimensionality
