mvabund (version 3.11.9)

antTraits: Ant data, with species traits

Description

Abundances of 41 epigaeic ant species across 30 sites in south-eastern Australia, with species trait and environmental data

Usage

data(antTraits)

Arguments

Format

A list containing three elements:
abund
A data frame with observations at 30 different locations of abundances of 41 epigaeic ant species.
env
A data frame containing 7 environmental variables from transects at each of the 30 sites:
Bare.ground
Percent cover of bare ground, as estimated from ten 1x1 metre quadrats
Canopy.cover
Percent canopy cover, as estimated from two 20x20m transects
Shrub.cover
Percent canopy cover, as estimated from two 20x20m transects
Volume.lying.CWD
Estimated volume of Coarse Woody Debris in two 20x20m transects, including all debris >5cm diameter.
Feral.mammal.dung
Proportion of quadrats including mammal dung, out of ten 1x1m quadrats.
traits
A data frame containing 5 species traits measured for each of the 41 species. Weber's length was log-transformed, Femur length was log-transformed then regressed against log(Weber's length), to remove the effect of size.
Femur.length
Residuals from regression of log(Femur length) against log(Weber's length)
No.spines
Number of spines on propodeum and petioles, as an integer value
Pilosity
A factor with four levels of pilosity, 0 = No or very few hairs; 1 = a sparse but regular covering of hairs; 2 = a consistent, moderate covering of hair; 3 = very dense hair covering
Polymorphism
0 = Monomorphic, 1 = polymorphic, 2 = dimorphic
Webers.length
log transformed. Body length, measured as the distance from the anterodorsal margin of the pronotum to the posteroventral margin of the propodeum
