Relationship between gross primary productivity and plant species richness at geographical scales: evidence from protected area data in China

The large-scale relationship between gross primary productivity (GPP) and plant species richness (PSR) remains a fundamental topic in macro-ecology. Although there have been numerous studies of the connection between GPP and PSR, this relationship (linear or unimodal) is still debatable at geographi...

Description
Summary:The large-scale relationship between gross primary productivity (GPP) and plant species richness (PSR) remains a fundamental topic in macro-ecology. Although there have been numerous studies of the connection between GPP and PSR, this relationship (linear or unimodal) is still debatable at geographical scales. Using geographically weighted regression and ordinary least squares, GPP and PSR data from protected areas in China were used to explore the complex relationship between GPP and PSR across different taxonomic groups (i.e. vascular plants, ferns, seed plants, gymnosperms, and angiosperms). Results showed that GPP was significantly related to PSR for all taxonomic groups at geographical scales ( p
