Description

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

Usage

aq.trans

Format

A data frame with 1637 rows 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.
