Subset of multiple years of demographic data of Succisa pratensis collected at the "Bennekomse Meent" site in the Netherlands. Details are described in Jongejans and de Kroon (2005). More information: E.Jongejans@science.ru.nl

The format is: chr "dataIPMpackSuccisa2"

data-frame with headings:

- size: log of the sum of the products of the number of leaves and the maximum leaf length for rosette and stem leaves at time t

- sizeNext: log of the sum of the products of the number of leaves and the maximum leaf length for rosette and stem leaves at time t+1

- stage: stage of the individual ('continuous' means the plant has a size; NA = not recruited yet) at time t

- stageNext: stage of the individual ('continuous' means the plant has a size; 'dead' = dead) at time t+1

- surv: survival (0 = dead, 1= alive, NAs if not yet recruited)

- offspringNext: type of new recruit ('sexual' = seedling, 'clonal' = side-rosette, NA = not a recruit) at time t+1

- fec1Bolt: whether stems are produced (0 = no stems, 1 = at least 1 stem, NA = not recruited yet) at time t

- fec2Stem: number of stems when stems are produced (NA when fec1Bolt = NA or 0) at time t

- fec3Head: mean number of flower heads per stem when stems are produced (NA when fec1Bolt = NA or 0) at time t

- fec1BoltNext: whether stems are produced (0 = no stems, 1 = at least 1 stem, NA = not recruited yet) at time t+1

- fec2StemNext: number of stems when stems are produced (NA when fec1BoltNext = NA or 0) at time t+1

- fec3HeadNext: mean number of flower heads per stem when stems are produced (NA when fec1BoltNext = NA or 0) at time t+1

- cloning: whether clonal offspring (side-rosettes) are produced by this individual (NA for plants that were not recruited yet at time t)

- clonesNext: number of clonal offspring (side-rosettes) produced when at least on side-rosette is produced (NA when 'cloning' = 0 or NA)
