Abstract
Understanding tree recruitment is needed to forecast future forest distribution. Many studies have reported the relevant
ecological factors that affect recruitment success in trees, but the potential for genetic-based differences in recruitment has
often been neglected. In this study, we established a semi-natural reciprocal sowing experiment to test for local adaptation
and microenvironment effects (evaluated here by canopy cover) in the emergence and early survival of maritime pine (Pinus
pinaster Aiton), an emblematic Mediterranean forest tree. A novel application of molecular markers was also developed to
test for family selection and, thus, for potential genetic change over generations. Overall, we did not find evidence to
support local adaptation at the recruitment stage in our semi-natural experiment. Moreover, only weak family selection (if
any) was found, suggesting that in stressful environments with low survival, stochastic processes and among-year climate
variability may drive recruitment. Nevertheless, our study revealed that, at early stages of recruitment, microenvironments
may favor the population with the best adapted life strategy, irrespectively of its (local or non-local) origin. We also found
that emergence time is a key factor for seedling survival in stressful Mediterranean environments. Our study highlights the
complexity of the factors influencing the early stages of establishment of maritime pine and provides insights into possible
management actions aimed at environmental change impact mitigation. In particular, we found that the high stochasticity
of the recruitment process in stressful environments and the differences in population-specific adaptive strategies may
difficult assisted migration schemes.
