Observatories and modelling


The research developed in the LTER site Jurassian Arc (ZAAJ) is characterised by the diversity of scope and the temporal and spatial resolutions considered. It also associates a wide range of non-conventional research partners – NGOs, government departments, local councils, etc.
Schéma conceptuel de monitoring adaptatif (d'après Lindenmayer et al. 2011)
One of the keys to the success of observatory and retro-observatory type approaches over the medium and long term is the capacity to include them in an adaptive monitoring process: the ‘development of conceptual models – co-definition of operational questions – co-construction of protocols for data collection, analysis and interpretation’ should be able to evolve steadily in response to new lines of questioning, information acquired or methodological advances without compromising the integrity and coherence of the data corpus.

Moreover, the complexity of socio-ecosystems makes the diversity of approaches to modelling necessary (statistics, mathematics, computer simulation) so as to understand and effectively predict their working, the responses to disturbances and their early effects (emergence of pathogens, modification of ecosystemic services, etc.).


The objectives of the LTER Jurassian Arc site are:
• to allow the development of environmental observational database management systems, making sure to develop standards for interoperability of data, so as to make possible coherent monitoring over time, a vision that cuts across the thematic lines of the workshop zone and meshes in with the other workshop zones.
• to describe, model and predict the patterns and processes of variation in space and time of the data collected, through effective collaboration of a core of researchers in mathematics, computer sciences, ecology and epidemiology.
This activity, conducted in a multidisciplinary context with multiple partner organisations, makes it possible both to reply to questions asked and to create the right seeding ground for the emergence of new lines of questioning.
