Joined and flat version of EDI data package knb-lter-hfr.118.33

Description

A fully joined and flat version of EDI data package knb-lter-hfr.118.33 (Ant Assemblages in Hemlock Removal Experiment at Harvard Forest since 2003) with all relevant ecocomDP L1 identifiers and content added. Use this dataset as an input to the L0_flat argument of the "create" functions.

Usage

ants_L0_flat

Format

A data frame with 2931 rows and 45 variables:

datetime: dates
block: block
plot: plot number
treatment: treatment type
moose.cage: location of grid with respect to moose exclosure
trap.type: trap type
trap.num: applies only to pitfall cups
subfamily: ant subfamily
hl: head length. We used trait definitions from Del Toro et al. (2015) and filled in missing species' data with information from Ellison et al.

nest.substrate: nest substrate
primary.habitat: primary habitat
secondary.habitat: secondary habitat associations
seed.disperser: whether or not a seed dispersing species
slavemaker.sp: whether or not a slavemaking species
behavior: classifications based on behavioral interactions with other ants
biogeographic.affinity: biogeographic affinity based on available occurrence records
