aq.trans: Annual transition data for Aquilegia in the southwestern US

Description

Transition data listing stages and fates from Aquilegia chrysantha in Fillmore Canyon, Organ Mountains, New Mexico, 1996-2003.

Usage

data(aq.trans)

Arguments

Format

A data frame with 1637 observations on the following 9 variables.

plot: Plot number
year: Staring year of census
plant: Plant id number
stage: Initial stage class with ordered factor levels seed < recruit < small < large < flower.
leaf: Total number of leaves
rose: Total number of rosettes
fruits: Total number of mature fruits
fate: Final stage class or fate with levels seed < recruit < small < large < flower < dead
rose2: Final number of rosettes

Details

The five stage classes include seeds in the seed bank, new recruits or seedlings, small vegetative plants with 1 rosette, large vegetative plants with 2 or more rosettes, and flowering plants. Stage classes were assigned to census plants using a combination of status and size data recorded in the field. See demo(stage.classify) for more details.
