The experimental design comprises every combination of three factors (community origin, soil nature and microclimate) for a total of 8 treatments.

Across our three main experiments we analysed variation in germination, survival, flowering time, and performance in relation to the main effects and interactions between origin soil type, source population nested within origin soil type, genotype, destination soil type or salinity treatment, and plot within soil type (for field and field soil experiments).
While this pattern does not satisfy the strict local versus foreign definition of local adaptation [ 4], the interaction term between the origin soil type and the destination soil type does indicate that there are segregating alleles that cause saline-origin genotypes to respond differently to saline field soils.
In addition, little is known about the origins of soil C and soil organic matter (SOM) stability after afforestation.
Carbonates and other calcium phases, having these a probable anthropogenic origin, are soil components containing major fractions of Pb, P, and Mn.
Longitudinal studies covering both wet and dry seasons are required to examine the hydrological influence on bird species and other similar biological communities by considering the origin, movement, soil profile, and minerals in surface and groundwater, as well as soil degradation and vegetation diversity, to better assess the relative contribution of anthropogenic and natural impacts.
The statistical unit was the tree with generally one tree replicate per origin and soil compartment.
The tree origin or soil type did not influence these results.
For beech, in the case of biomass, leaf colour and size measurements, individual values represented averages of two trees per origin and soil compartment.
