European Farmland Bird Distribution Explained by Remotely Sensed Phenological Indices

摘要: Birds are important components of biodiversity conservation since they capable indicating changes in the general status wildlife and countryside. The Pan-European Common Bird Monitoring Scheme (PECBM) has been launched by BirdLife Partnership Europe, where European Census Council collecting data from 20 independent breeding bird survey programs across Europe over last 25 years. These show dramatic declines farmland birds. We suggest that seasonal characteristics vegetation cover derived high temporal resolution remote sensing images could facilitate monitoring suitability habitats, these indicators may be a better choice for than climate data. used redundancy analysis to link PECBM estimated number birds set phenological climatic biogeographic regions Europe. Variance partitioning was account variation explained variables area environmental strata individually, define pure effect variables, extract total variance. revealed statistical significance (p < 0.001) correlations between species environment. Phenological indices 38% variance community composition 23 species, whereas 30% After other as covariables, phenology, climate, were 16%, 8%, respectively. Based on probability results, we supply continental scale studies only. In addition, cost time effective, continuous scale, readily repeatable large spatial coverage while supplying standardized results.
