Tree-nesting ants in rainforest plots at three elevations, Papua New Guinea

Real field data: every ant nest in 1254 trees within continuous plots of primary rainforest at Wanang (200 m), Numba (900 m) and Yawan (1800 m), Papua New Guinea (Plowman et al. 2020). Only the 769 trees with at least one nest appear. Each row is one ant species nesting in one tree.

Usage

png_tree_ants

Format

A tibble with one row per tree and ant species, and nine columns:

site: Plot: "Wanang", "Numba" or "Yawan".
elevation: Elevation of the plot in metres.
subplot: Subplot within the plot.
tree: Tree identifier.
tree_family, tree_genus: Host tree family and genus.
dbh: Tree diameter at breast height (cm).
species: Ant morphospecies code.
nests: Number of nests of the species in the tree.
