Integrated effects of neighborhood composition and resource levels on growth of a dominant tree species in a tropical forest

Abiotic environments and biotic neighborhoods interact to influence plant growth and community assembly. However, the nature of this interaction depends very much on how biotic neighborhoods are measured, including their relatedness to focal plants. In a tropical seasonal rainforest, we examine the growth of a dominant canopy species in response to environmental factors, the densities and relatedness of conspecific and heterospecific neighbors, and their interactions. We find significant environmental effects and conspecific negative density dependence on growth. Furthermore, conspecific neighbor density has stronger negative effects on growth under high light and soil water resource levels, but weaker negative effects under low light and soil water resource levels. In addition, more closely related heterospecifics in the neighborhood have negative effects on growth under high soil phosphorus availability, but positive effects under low soil phosphorus availability. In contrast, more cl..., , , # Integrated effects of neighborhood composition and resource levels on growth of a dominant tree species in a tropical forest

## Description of the data and file structure

This study examined the tree growth of a dominant canopy species in response to abiotic environmental factors, conspecific and heterospecific neighbor densities, and intra-specific genetic-relatedness and inter-specific phylogenetic-relatedness, as well as their interactions, in a tropical seasonal rainforest. We found both of abiotic environments and conspecific neighbors play important roles. Furthermore, the neighborhood effects veried with resource levels, enhancing our understanding of the complex dynamics within forest communities.

The data includes tables, R code, DNA sequence matrix and phylogenetic tree.
