Ecological Indicators

Systems for assessing the ecological status of lakes with respect to fish population are normally based on catches using conventional European Committee for Standardization (CEN) gill nets. A modified gillnet (MOD) design with less small-mesh and more large-mesh panel area , developed to reduce catch and mortality while retaining the information needed for ecological assessment, was previously de…

Accurate mapping of actual irrigated cultivated land is essential for understanding the interactions between human agricultural activities and regional agricultural ecosystem, particularly in large basins with strong climatic and ecological heterogeneity. As a typical arid and semi-arid region, the Yellow River Basin (YRB) is facing prominent contradictions between agricultural water use and ecol…

Soil multitrophic diversity and plant diversity are critical for ecosystem stability, yet their impacts remain poorly understood. Here, we performed an extensive survey across the Tibetan Plateau to examine the impacts of species pool size (γ-diversity), local richness (α-diversity), and species turnover (β-diversity) of soil multitrophic communities and plants on temporal ecosystem stability. Ou…

Intense human activities pose continuous threats to regional ecological security. However, current assessments of human-ecosystem interactions predominantly build upon static spatial correlations, which inherently fail to capture complex, nonlinear evolutionary trajectories. To fill this research gap, this study constructs an innovative dual-dimensional diagnostic framework named “State-Process”,…

Given escalating water scarcity and rapid urbanization, characterizing the long-term evolution of surface water environments across the Beijing-Tianjin-Hebei (BTH) region is vital for coordinated regional development. Using Landsat imagery spanning 1984–2024, this study quantified Secchi disk depth ( Zsd ) dynamics in 1105 water bodies across the BTH region and identified the dominant drivers thr…
