Large trees are surrounded by more heterospecific neighboring trees in Korean pine broad-leaved natural forests

Abstract Negative conspecific density dependence is one of the principal mechanisms affecting plant performance and community spatial patterns. Although many studies identified the prevalence of density dependent effects in various vegetation types by analyzing conspecific spatial dispersal patterns...
