Patch Area and Soil Resource Availability Outweigh Heterogeneity in Shaping Karst Plant Diversity During Early Restoration. [PDF]

Ecol Evol
Patch area strongly influenced species and phylogenetic diversity in karst areas. Soil resource availability increased species and phylogenetic diversity. Soil nutrient heterogeneity shaped phylogenetic structure in early karst restoration. Patch shape and soil resource quantity outweighed heterogeneity in karst diversity.
