Pack: Transient dynamics pack

Description:

This is a .txt file of a stage matrix 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: Life Table Response Experiments (LTRE)_Year Effect One Location V1 (http://www.myexperiment.org/packs/590.html)

Description:

This documentation (tutorial to run the workflow) explains how to run a workflow that belongs to the pack with same name.

The Transient dynamics or Calculate population growth rates by projection Workflow provides an environment to calculates the population growth rate and stable stage distribution by repeated projections of the equation n(t+1)=An(t) and to produce plots of the short-term dynamics and convergence to stable stage distribution using stage vector projections.

1. Transient dynamic analysis

• Population projection

• Lambda or dominant eigenvalue

• The stable stage distribution (stable.stage)

• Stage vector (stage.vectors)

• Population sizes (pop.sizes)

• Population change (pop.changes)

   2. Damping ratio

Description:

This workflow produces plots of the short-term dynamics and convergence to stable stage distribution using stage vector projections.

This workflow has been created by the Biodiversity Virtual e-Laboratory (BioVeL http://www.biovel.eu/) project. BioVeL is funded by the EU’s Seventh Framework Program, grant no. 283359.

This workflow was created based on Package ‘popbio’ in R.
