# Data for: Compound environmental pathways shape provincial avian diversity in inland China ## 1. General Information- Journal: Diversity and Distributions- Authors: Xinrui Zhou †, Peng Guo †, Jiaxu Fan, Yi Lian *, Hongyuan Huo, Lei Cui, Xunqiang Mo *, Zhengwang Zhang († These authors contributed equally to this work and share first authorship.) (* Corresponding authors.)- Contact Emails: lianyi@tjnu.edu.cn (Y. Lian); 421973@163.com (X. Mo) ## 2. Data SourcesThe primary datasets supporting this study were integrated from public databases. Due to platform policies and size constraints, raw multi-year point records and global raster datasets are not directly uploaded here, but their sources are detailed below: - Avian Observation Data (2015–2021): Occurrence records were integrated from eBird (https://ebird.org/home) and the China Bird Report Center (http://www.birdreport.cn) to mitigate platform-specific sampling biases, improve spatial-temporal coverage at the provincial scale, and enhance the robustness of macroecological inferences.- Environmental and Anthropogenic Drivers: Based on established macroecological frameworks (Coelho et al., 2023; Deshpande et al., 2022; Wu et al., 2024), predictors for hydrology, vegetation, temperature, and snow were collected from the ERA5-Land dataset (Muñoz-Sabater et al., 2021), which provides temporally consistent land-surface climatic variables. Anthropogenic drivers, represented by Gross Domestic Product (GDP) and population size, were sourced from the "China Statistical Yearbook" (National Bureau of Statistics, 2023).
