The downscaling of historical climate data for application to the BCM to calculate hydrologic response to ongoing changes in climate has provided a dataset rich in regional representation of climatic and hydrologic trends, but spatially detailed enough to provide fine-scale examples of local impacts of climate on the landscape.
Figure 6 depicts the graphical representation of climatic variables and vegetation obtained through NDVI.
The graph allows the representation of climatic variables, the definition of comfort zones, the selection of bioclimatic design resources and the evaluation of indoor temperatures, measured in actual buildings or obtained from computer simulations.
Exposure scenarios are based on global climate scenarios: internally consistent representations of future climatic conditions.
The relative positioning of points in this plot provided a graphical representation of the climatic similarity of the observations, with close points being more similar and distant points being more different.
During the last glacial maximum (LGM) the potential distribution of the two species increased to cover most of their current ranges: for A. ramblae only the northernmost known locality was outside the potential LGM distribution (Alcampell, in the province of Huesca), which was also an outlier in the representation of the climatic niche of the species (Additional file 14: Figure S7).
To ensure fair representation of all three climatic conditions, we selected one-half of the kebeles in each climatic zone using a lottery method.
In addition, ENMs as applied here are a representation of each species' climatic niche, but if a species is restricted from exploiting its full climatic niche due to other factors, projections onto past climates may exclude potentially habitable areas [ 64].
Fragmentation of the remaining model sets within the expected distribution was minimal, particularly for the soils runs, indicating good representation of the fundamental climatic space for each species.
