Plant species composition and distribution in Caryopteris mongolica community in Northwestern China

Based on the analysis objects of Caryopteris mongolica communities distributed in typical steppe, desertified steppe and deserts, to investigate the relative effects of environmental factors on species distribution and diversity in C. mongolica communities and how they changed with environmental conditions, which provide a scientific basis for understanding how climate change affects biodiversity across regions. We selected a total of 34 representative C. mongolica community sites in northern China, and their community composition was studied using the sample plot survey method.

Redundancy analysis (RDA), Pearson correlation and generalized summation models (GAMs) were used to explore the effects of environmental heterogeneity on species distribution and species diversity in the communities.
