  abstract = {{M}icrogeographical adaptation occurs when the effects of directional selection persist despite gene flow. {T}raits and genetic loci under selection can then show adaptive divergence, against the backdrop of little differentiation at other traits or loci. {H}ow common such events are and how strong the selection is that underlies them remain open questions. {H}ere, we discovered and analysed microgeographical patterns of genomic divergence in four {E}uropean and {M}editerranean conifers with widely differing life-history traits and ecological requirements ({A}bies alba {MI}ll., {C}edrus atlantica [{E}ndl.] {M}anetti, {P}inus halepensis {M}ill. and {P}inus pinaster {A}iton) by screening pairs from geographically close forest stands sampled along steep ecological gradients. {W}e inferred patterns of genomic divergence by applying a combination of divergence outlier detection methods, demographic modelling, {A}pproximate {B}ayesian {C}omputation inferences and genomic annotation to genomic data. {S}urprisingly for such small geographical scales, we showed that selection is strong in all species but generally affects different loci in each. {A} clear signature of selection was systematically detected on a fraction of the genome, of the order of 0.1%-1% of the loci depending on the species. {T}he novel modelling method we designed for estimating selection coefficients showed that the microgeographical selection coefficient scaled by population size ({N}s) was 2-30. {O}ur results convincingly suggest that selection maintains within-population diversity at microgeographical scales in spatially heterogeneous environments. {S}uch genetic diversity is likely to be a major reservoir of adaptive potential, helping populations to adapt under fluctuating environmental conditions.},
