The age-specific survival analysis workflow gives the basic information on age-specific survival, this includes the mean, variance and coefficient of variation (cv) of the time spent in each stage class and the mean and variance of the time to death.

Fundamental matrix (N): is the mean of the time spent in each stage class.

Variance (var): is the variance in the amount of time spent in each stage class.

Coefficient of variation (cv): is the coefficient of variation of the time spent in each class (sd/mean- the ratio of the standard deviation to the mean).

Meaneta: is the mean of time to death, of life expectancy of each stage.

Vareta: is the variance of time to death.

Name	Description
stage_matrix_file	The stage matrix file input port: Here comes the stage matrix without the stage names (as you see in the example). It should be provied as a txt-file. Example from: J. Gerard B. Oostermeijer; M.L. Brugman; E.R. de Boer; H.C.M. Den Nijs. 1996. Temporal and Spatial Variation in the Demography of Gentiana pneumonanthe, a Rare Perennial Herb. The Journal of Ecology, Vol. 84(2): 153-166.
stages	Stage: Here come the names of the stages or categories of the input matrix. It is very important that the stages names are not longer than 8 characters. The name of the stages must be added one by one. The respective name stages must be filled one by one. First press add value, fill a stage name (not longer than 8 characters) and press enter, then press add value and fill once again the next stage name, repeat the action until you have fill all the stages names. In the following example, the matrix has 5 stages or categories: S J V G D S 0.0000 0.0000 0.0000 7.6660 0.0000 J 0.0579 0.0100 0.0000 8.5238 0.0000 V 0.4637 0.8300 0.9009 0.2857 0.8604 G 0.0000 0.0400 0.0090 0.6190 0.1162 D 0.0000 0.0300 0.0180 0.0000 0.0232 The stages of this matrix are called: 1) Seedlings S 2) Juveniles J 3) Vegetative V 4) Reproductive individuals G 5) Dormant plants D
rows_fecundity	To perform the Age-specific survival analysis, the row(s) in which the recruitment values are found, should be selected. In the example of the Gentiana species (Oostermeijer et al. 1996. The Journal of Ecology): Selected lines are S and J (seedlings and juveniles, these stages receive recruits each year from the stage G): therefore, the numbers 1 and 2 are used to identify these rows. S J V G D S 0.0000 0.0000 0.0000 7.6660 0.0000 J 0.0579 0.0100 0.0000 8.5238 0.0000 V 0.4637 0.8300 0.9009 0.2857 0.8604 G 0.0000 0.0400 0.0090 0.6190 0.1162 D 0.0000 0.0300 0.0180 0.0000 0.0232
columns_fecundity	To perform the age-specific survival analysis, the column(s) in which the fecundity values are found, should be selected. In the example of the Gentiana species (Oostermeijer et al. 1996. The Journal of Ecology): The selected column is G (reproductive individuals): therefore number 4 will be used to identify the fecundity column (G). S J V G D S 0.0000 0.0000 0.0000 7.6660 0.0000 J 0.0579 0.0100 0.0000 8.5238 0.0000 V 0.4637 0.8300 0.9009 0.2857 0.8604 G 0.0000 0.0400 0.0090 0.6190 0.1162 D 0.0000 0.0300 0.0180 0.0000 0.0232

Name	Description
Age_specific_survival	The age specific survival workflow gives the basic information on the mean, variance and coefficient of variation (cv) of the time spent in each stage class and the mean and variance of the time to death. Fundamental matrix (N): is the mean of the time spent in each stage class. e.g.:For our Gentiana example means a J plants will spends, on average, about 1 year as a Juvenile, 12 as vegetative plant, less than a year a reproductive and dormant plant. Variance (var): is the variance in the amount of time spent in each stage class. Coefficient of variation (cv): is the coefficient of variation of the time spent in each class (sd/mean- the ratio of the standart deviation to the mean). Meaneta: is the mean of time to death, of life expectancy of each stage. e.g.:The mean age at death is the life expectancy; the life expectancty of a new individual seedling is 8 years. Vareta: is the variance of time to death.
