Modelling Platform
The EVOLTREE modelling platform served to exchange data between a number of genetic and ecological models. Output of one model could be used as input of another, while the platform took care of the necessary conversion and realignment of the data. The EVOLTREE modelling platform group focussed on forest dynamic models.
Since the EVOLTREE project ended in 2011, the modelling platform is not maintained any more. This page here now contains a review on the used models, and it allows to download additional software and documents.
Models
-
Logo Name Description 
Eco-Gene
individual-based simulation model to study the temporal and spatial dynamics of genetic and demographic processes in tree populations
ForGEM
simulates the growth and development of individual trees, on a scale up to several hectares
TransPopRege
transitionnal populations study; ecological factors shaping the genetic quality of seeds and seedlings in forest trees
VentouG
semi-spatialized model (nearly a gap model) dealing with the evolution of artificial pine stands towards mixed stands (pines, beech, silver fir) on the Mont-Ventoux (mediterranean mountain)
MetaPop
evolution of diversity is simulated within a set of populations exchanging genes and undergoing various evolutionary scenarios

From the EVOLTREE project:
- EvolTree Modelling Platform Starter Application
The EvolTree Modelling Platform Starter Application is a tiny program that takes its instructions from the Modelling Platform at this website, unpacks the data and invokes the appropriate model.

FormatIn is a Perl script to transform genotypic data produced by the different simulation programs of the modeling platform into the input format required by several population genetic programs (Arlequin, Cervus, FSTAT, GDA_NT, GenePop, MLTR, POLDISP, SGS, SPAGeDi, Structure, and Swap). It will run on personal computers and workstations that have Perl installed. A short manual is distributed with the script.

- Stand Visualization System
The Stand Visualization System or SVS generates graphic images depicting stand conditions represented by a list of individual stand components, e.g., trees, shrubs, and down material. The images produced by SVS, while abstract, provide a readily understood representation of stand conditions. Images produced using SVS help communicate silvicultural treatments and forest management alternatives to a variety of audiences. SVS displays stand information represented by a list of individual plant and log components in a realistic, although abstract, fashion; displays stand information in a manner that communicates the overall structural diversity present within the stand; differentiates between stand components using different plant forms, colors, or other types of marking; provides overhead, profile and perspective views of a stand;

TreeMBase
-
The goal of the development of the TreeMBase tool was to manage the data needed or produced by the models:
- For each model, it was a tool to store their input/output data. Different cases appeared: for ForGem, as the data processing is already based on databases, the work consisted in integrating their structure in the TreeMBase. For other models which use an inventory file as input for example, the database would store the file content.
- The generation of input data/parameters based on the data shared in the database will allow as example: two different models to use the same input data for model comparison; to use output data of one model as input of another one.
- The development of the TreeMBase should not modify the way models are running.
