Exploring the factors that drive changes in biodiversity is a hot and critically important topic landscape ecology biogeography. In this study, semi-structured citizen science data bird distribution maps were employed to gather from 2015 2020 for calculation of species richness, Shannon index, Pielou index Anhui Province. These metrics utilized assess avian elucidate spatial patterns across region. research, structural equation model (SEM) was investigate relationships between three dimensions structure, urban development intensity, environmental on biodiversity, conceptual framework established identify key driving factors. The validity, reliability, fit hypothesized substantiated through rigorous testing, demonstrating its reasonableness. results indicate following: (1) composition configuration play crucial roles influencing diversity. An increased proportion cultivated land negatively impacts diversity, whereas expansion forested areas promotes it. At level, Largest Patch Index (LPI) significantly enhances serving as primary force. Landscape structure affects diversity both directly, composition, indirectly, configuration. (2) dimension intensity generally shows significant negative impacts; among these, GDP has greatest comprehensive impact impact. (3) Topography overall factors, with predominantly direct positive effect. (4) Overall, are main forces Province, which effect intensity. provide an scientific basis planning ecological protection inspiration assessing animal plant other regions.

Soil bacterial diversity often shows different trends due to changes in dominant plant species. However, the potential key drivers of processes that reveal diversity per se have not been clearly elucidated. We established a field experiment with 9 native grassland species and assessed relationship between soil ecological taxa classified by network construction. A co-occurrence 1065 points 10023 edges, among grasses, was classify microbial taxa. The results showed relative abundance as peripherals, which is influenced urease activity, inhibited diversity. Conversely, specific directly controlled plants positively related Further, composition peripherals affected physicochemical properties, while NO₃^-, TP, AP, SU, TC AK. responses properties their sensitivity environmental changes. Our findings plant-dominated closely linked peripheral Understanding these mechanisms may provide new insight management microbes through selection grass following disturbance subsequent restoration.
