Data from the study of adaptive value and gene flow effects on populations inhabiting marginal using in situ common gardens

Data from a conducted study on the effects of different gene flow provenance on marginal
populations of Mediterranean alpine Silene
ciliata Pourret (Caryophyllaceae) replicated in three mountain ranges of
Central Spain. We experimentally tested the effect of three different types of
pollen-mediated gene flow on germination rate, seedling size and survival rate
in marginal populations and assessed their effects by establishing in situ common gardens. The three different types of pollen-mediated gene flow were; within marginal population, and between marginal-marginal and optimal-marginal populations. To further assess
the evolutionary potential of marginal populations, we performed a reciprocal
sowing experiment and measured the same fitness components to determine the
extent of local adaptation.
