Ecological Indicators

The distribution characteristics, concentration dynamics, and organic matter (OM) interactions of different phosphorus (P) species in lake sediments are fundamental to understanding P cycling and release mechanisms. This study investigated P speciation, concentrations, and their associations with OM in the sediments and pore water of Lake Dian, with a focus on spatial heterogeneity and centennial…

Understanding ecological network resilience is essential for maintaining ecosystem structure and function under increasing anthropogenic disturbance. This study evaluated the spatiotemporal evolution and resilience characteristics of the ecological network in Yantai City from 2003 to 2023 by integrating the InVEST model, circuit theory, and robustness analysis. As a rapidly urbanizing coastal cit…

Fractional Vegetation Cover (FVC) is a key biophysical parameter for characterizing vegetation dynamics and ecosystem functioning, and is essential for ecological monitoring in arid and semi-arid regions. However, sparse vegetation and strong soil background effects in these regions lead to substantial variability in the applicability and stability of different inversion models, thereby limiting …

Streamflow duration assessment methods (SDAMs) are rapid tools for reach-scale streamflow duration classification. SDAMs use single-visit indicator data as surrogates because direct measurement of long-term flow duration is resource intensive. Algae (diatoms and soft-bodied algae) are potentially strong indicators of streamflow-duration class (SDC) because of geographical ubiquity and biodiversit…
