Plant traits for 136 species

Description

This dataset, from the library cluster, describes 136 plant species according to biological attributes (morphological or reproductive).

Usage

data(plantTraits)

Format

A data frame with 136 observations on the following 31 variables.

pdias: Diaspore mass (mg).
longindex: Seed bank longevity.
durflow: Flowering duration.
height: Plant height, an ordered factor with levels '1' < '2' < ... < '8'.
begflow: Time of first flowering, an ordered factor with levels '1' < '2' < '3' < '4' < '5' < '6' < '7' < '8' < '9'.
mycor: Mycorrhizae, an ordered factor with levels '0'never < '1' sometimes< '2'always.
vegaer: Aerial vegetative propagation, an ordered factor with levels '0'never < '1' present but limited< '2'important.
vegsout: Underground vegetative propagation, an ordered factor with 3 levels identical to 'vegaer' above.
autopoll: Selfing pollination, an ordered factor with levels '0'never < '1'rare < '2' often< the rule'3'.
insects: Insect pollination, an ordered factor with 5 levels '0' < ... < '4'.
wind: Wind pollination, an ordered factor with 5 levels '0' < ... < '4'.
lign: A binary factor with levels '0:1', indicating if plant is woody.
piq: A binary factor indicating if plant is thorny.
ros: A binary factor indicating if plant is rosette.
semiros: Semi-rosette plant, a binary factor ('0': no; '1': yes).
leafy: Leafy plant, a binary factor.
suman: Summer annual, a binary factor.
winan: Winter annual, a binary factor.
monocarp: Monocarpic perennial, a binary factor.
polycarp: Polycarpic perennial, a binary factor.
seasaes: Seasonal aestival leaves, a binary factor.
seashiv: Seasonal hibernal leaves, a binary factor.
seasver: Seasonal vernal leaves, a binary factor.
everalw: Leaves always evergreen, a binary factor.
everparti: Leaves partially evergreen, a binary factor.
elaio: Fruits with an elaiosome (dispersed by ants), a binary factor.
endozoo: Endozoochorous fruits, a binary factor.
epizoo: Epizoochorous fruits, a binary factor.
aquat: Aquatic dispersal fruits, a binary factor.
windgl: wind dispersed fruits, a binary factor.
unsp: Unspecialized mechanism of seed dispersal, a binary factor.

Details

Most of factor attributes are not disjunctive. For example, a plant can be usually pollinated by insects but sometimes self-pollination can occur.
