Resumo
The Stochastic Dynamic Methodology (StDM) is a mechanistic framework for simulating ecological processes,
based on statistical parameter estimation methods. This methodology is a sequential modelling
process primarily developed to predict impacts of anthropogenic activities in the ecological status of
ecosystems. Over the last years, this approach was increasingly tested and advances as well as limitations
have clearly emerged from the different ecological contexts, scales and target organisms, guilds
and/or communities studied. We review the performance of the StDM applications, by system types
and upgraded innovation. Most published papers with StDM models were dedicated to assess anthropogenic
pressures in the scope of the ecological integrity problematic by using the state variables as
ecological indicators. We discuss the StDM concepts, requirements, ecological relevance, universality
and the current spatial integration with Geographic Information Systems (GIS) and other types of modelling
approaches. Additionally, we describe a simple demonstrative application in order to illustrate the
framework methodological steps, supporting the theoretic concepts previously presented with a study
case background.
