Phylogenetic tree for forest invader trait analysis

Description

A phylogenetic tree object containing 76 woody plant species (44 native and 32 non-native) used in the analysis of functional trait syndromes for forest invaders in North American deciduous forests. The tree is based on species-level phylogeny with aged branch lengths and includes native, naturalized, and invasive species classifications.

Usage

forest_invader_tree

Format

A phylo object with:

edge

A 142 x 2 matrix defining the tree topology

edge.length

A numeric vector of 142 branch lengths

Nnode

Number of internal nodes (67)

node.label

Character vector with node labels including taxonomic groups

tip.label

Character vector of 76 species names

Details

The phylogenetic tree was constructed using correlation matrix of phylogenetic distances calculated with an aged tree based on the species-level phylogeny. The tree includes representatives from major angiosperm families and is used for phylogenetically independent contrasts in trait analysis. Branch lengths reflect evolutionary time, and the tree structure allows for proper phylogenetic corrections in comparative analyses of functional traits between native and invasive species.

Species include shrubs and vines from deciduous forests, with invasive species representing those managed as high-impact invaders in northeastern United States, and naturalized species representing non-native species that have established but are not considered highly invasive.
