Figure 3From: Patterns of contemporary hybridization inferred from paternity analysis in a four-oak-species forestPollen flow between four oak species and their hybrids detected in our sample. The assignment of adult individuals in pure species and hybrid oaks was made by Structure software without any prior information on morphology [24]. Species names were abbreviated as follows: Rob - Q. robur; Pet - Q. petraea; Pub - Q. pubescens; Fra - Q. frainetto, Hyb - hybrids between pairs of species.Back to article page
