Although distant populations of a given species may show local adaptations to diverging environmental conditions, traditional SDMs disregard intraspecific variation. Yet, incorporating genetic information into SDMs could improve predictions. Here we aimed at investigating whether genetically informed SDMs would outperform traditional SDMs. Using published information on the spatial genetic structure of the European Beech Fagus sylvatica L. (1753), we built lineage-specific SDMs for each phylogenetic group of the species. We then combined all lineage-specific SDMs into a single genetically informed SDM that we compared against a traditional SDM approach. We finally compared SDMs’ predictions against independent datasets of present-day distribution as well as fossil distribution data from the Mid-Holocene, using six metrics of model performance. We found that aggregating lineage-specific SDMs into a single genetically informed SDM increased model performances to identify suitable areas currently occupied by F. sylvatica. In comparison to a traditional SDM, the genetically informed SDM we built for F. sylvatica assigned higher probabilities of occurrence during the Mid-Holocene at locations where fossil records were found. Aggregating lineage-specific SDMs into a single genetically informed SDM seems to outperform the traditional SDM approach, especially so when the aim is to identify potentially suitable areas of occupancy. This could be particularly useful for the identification of cryptic refugia that remain undetected by traditional SDMs. Genetically informed SDMs have the potential to improve our understanding of species redistribution under climate change.

This paper is an example of the latter type of GIS use for reconstruction of the Holocene Rhine-Meuse delta (128x75 km; part of the Dutch coastal plain). Depositional traces of river courses (channel belts) are major features to map. We digitized mapped channel belt fragments and stored their reconstructed ages in a linked table. The GIS data structure allows checking for internal consistency of the implemented reconstruction, enabling iterative improvement while digitizing and labelling. Palaeogeographical maps for any given time during the Holocene result from GIS-database queries. Coupled to the GIS are high-resolution digital elevation data (sub-decimetre accurate laser-altimetry data covering the entire study area) and a database of ca 100000 borehole descriptions, allowing for further mapping improvements. The GIS structure and digital data together greatly improved mapping and enable larger areas to be mapped in greater detail with greater accuracy and in less time.
