Bayesian updating in causal probabilistic networks by local computations
Combining replicated real-world experiments, which take advantage of implemented mitigation measures or other forms of human impact, with research-led experimental manipulations can provide powerful scientific tools for inferring causal drivers of ecological change and the generality of their effects.Additionally, combining these two approaches can facilitate communication with stakeholders involved in implementing management strategies.

Second, in the worst case, the DFS algorithm explores the search space of all elimination orders, which has size n!Human-induced environmental changes are causing major shifts in ecosystems around the globe.
To support environmental management, scientific research has to infer both general trends and context dependency in these shifts at global and local scales.

The first explores the last decades of Anglo-Saxon England including links between England and Normandy before 1066; the second investigates the succession crisis of the 1060s, the invasion of 1066 and the subsequent resistance and rebellions while the third addresses the impact of the Norman Conquest on different aspects of government and society, including landholding and lordship, the church and the physical landscape.
Multiply sectioned Bayesian networks (MSBNs) provide a coherent and flexible formalism for representing uncertain knowledge in large domains.
Global consistency among subnets in an MSBN is achieved by communication.
We demonstrate such an integrative approach using the case study Eco Impact, which aims at empirically unravelling the impacts of wastewater-born micropollutants on aquatic ecosystems.
