Information Description

This is a .txt file of four years demographic data of the species: Gentiana pneumonanthe, collected and published by Gerard Oostermeijer (Instituut voor Biodiversiteit en Ecosysteem Dynamica (IBED), Universiteit van Amsterdam).

This file allow users to run the workflow Creation of a stage matrix model from demographic monitoring of individuals in an animal or plant population (http://www.myexperiment.org/workflows/3276.html) or Matrix Population Model construction and analysis v19 (http://www.myexperiment.org/workflows/3684.html)

The input data has to have the format of a table containing the demographic data on a series of individuals in two years. Each individual has a table row for each year and is identified by a number (plant column in example). For the year specified in the column 'year', each individual has a certain life stage ('stage'). The stage codes can be chosen by the user, but they have to be specified with a string (limit to characters) . The stages names cannot be longer than 8 characters. For all individuals, the number of offspring is specified in a chosen way (in the example, 'repstr' gives the number of flowers/fruits for each plant. In the example, it can be seen that only generative adults (stage=G) had flowers. Individuals without offspring have to be indicated by filling in '0' in this column, which cannot have empty cells. The column 'recruitment' specifies those individuals that are new in the second year census to the population by means of a code. In the example, 'RS' is a new seedling, and 'RJ' a new juvenile plant. As can be seen in the example, no code is needed in this column for individuals that were already present.
