Population Data of Pelican Species (Great White Pelican and Dalmatian Pelican) at the Anzali Wetland.xlsx

The aim of this manuscript is to compare the wintering population trends of the Dalmatian Pelican and Great White Pelican at the Anzali International Wetland over a 15-year period (2007-2021) regarding climate factors. The study also aims to determine the climate parameters with the highest impact on the wintering populations of these two species. The findings of this research have shown us how the population trends of the species are correlated to the relevant climate parameters and how they interact. In addition, the results of different statistical analyses in R programming language have indicated the most effective climate parameters, and the trend analysis has also defined the 15-years trends of both species` populations.

本研究旨在结合气候因子，对比2007-2021年这15年间安扎利国际湿地（Anzali International Wetland）内卷羽鹈鹕（Dalmatian Pelican）与白鹈鹕（Great White Pelican）的越冬种群动态。同时，本研究还旨在明确对这两种鸟类越冬种群影响最为显著的气候参数。本研究结果揭示了这两个物种种群动态与相关气候参数之间的关联及相互作用机制。此外，通过R编程语言（R programming language）开展的各类统计分析进一步确定了核心影响气候参数，而趋势分析则明确了两种鸟类15年间的种群动态变化趋势。
