“…In agreement with the well-known strong population differentiation for neutral markers (Grivet et al 2009;Kurt et al 2011b), and for a number of adaptive traits (reviewed in Chambel et al 2013), within species variation in growth and survival was also found to be extensive for both the Aleppo and the Brutia pine. Previous results suggested that the relative performance of the populations depended on the environmental conditions of the testing sites (Atzmon et al 2004;Schiller and Atzmon 2009;Taïbi et al 2015).…”

“…Significant (p < 0.05) deviations from the full model are highlighted in bold font stress in the two test sites. P. halepensis is typically assumed to be more drought tolerant than P. brutia (Chambel et al 2013;Schiller 2000), so the better average growth and survival of Brutia pine populations may therefore suggest that the experimental conditions were not, in fact, so harsh.…”

“…(Aleppo pine) and Pinus brutia Ten. (Turkish red pine or Brutia pine) are closely related taxa of the Mediterranean Basin that were once considered as subspecies of the complex halepensis/brutia group but now are recognized as independent species (Chambel et al 2013;Phillips and Gladfelter 1991). The two species are photophilous fastgrowing colonizers especially adapted to low moisture conditions.…”

“…Both species encounter each other in some areas of Greece and Turkey, where they naturally hybridize, with unidirectional introgression from P. halepensis to P. brutia (Bucci et al 1998). Between them, P. halepensis and P. brutia cover more than 7 million ha in the Mediterranean basin (Chambel et al 2013). Despite their phylogenetic proximity, the two species showed marked divergence for several key adaptive traits (Grivet et al 2013), resulting in contrasting performance when planted together in different environmental conditions (Bariteau and Pommery 1992;Fisheri et al 1986;Kaundun et al 1997;Weinstein 1989).…”

& Key message Adaptation of Pinus brutia and Pinus halepensis to harsh Moroccan environments varied considerably among populations, with variation following marked geographic clines. & Context Mediterranean pines are drought tolerant species that play relevant ecological and economic roles in North Africa. Mediterranean pines harbor huge intraspecific variation in adaptive traits. & Aims Exploring the relative performance of different seed sources and analyzing the genotype by environment (G × E) interaction becomes, thus, essential for maximizing the efficiency of any reforestation program. & Methods We present the results of a comprehensive quantitative analysis of growth, survival, and resistance to the processionary moth of 57 populations of P. halepensis Mill. and P. brutia Ten. tested under severe drought conditions in two contrasting Moroccan test sites differing in water regime, soil, and physiographic conditions. & Results The results indicated the existence of considerable variation between species and among populations within species in growth, survival, and susceptibility to the processionary moth (Thaumetopoea pityocampa Dennis & Schiff.), but low plasticity across sites, despite the apparently large environmental differences between them. On average, P. brutia performed better than P. halepensis. The G × E interaction was significant for all traits and ages, but an in-depth analysis revealed that the main source of the interaction was due to large differences in residual variances across sites, while the relative population ranks remained highly consistent across sites. & Conclusion Growth and survival of Aleppo pine populations followed well-defined geographical clines, with populations from the Eastern range of the distribution, particularly those of Greece, showing outstanding performance.

The contribution of genetic adaptation and plasticity to intraspecific phenotypic variability remains insufficiently studied in long‐lived plants, as well as the relevance of neutral versus adaptive processes determining such divergence. We examined the importance of phylogeographic structure and climate modulating genetic and plastic changes and their interdependence in fitness‐related traits of a widespread Mediterranean conifer (Pinus pinaster). Four marker‐based, previously defined neutral classifications along with two ad hoc climate‐based categorizations of 123 range‐wide populations were analyzed for their capacity to summarize genetic and plastic effects of height growth and survival (age 20) in 15 common gardens. Plasticity of tree height and differential survival were interpreted through mixed modeling accounting for heteroscedasticity in the genotype‐by‐environment dataset. The analysis revealed a slight superiority of phylogeographic classifications over climate categorizations on the explanation of genetic and plastic effects, which suggests that neutral processes can be at least as important as isolation by climate as driving factor of evolutionary divergence in a prevalent pine. The best phylogeographic classification involved eight geographically discrete genetic groups which explained 92% (height) and 52% (survival) of phenotypic variability, including between‐group mean differentiation and differential expression across trials. For height growth, there was predictability of plastic group responses described by different reaction norm slopes, which were unrelated to between‐group mean differentiation. The latter differences (amounting to ca. 40% among groups) dominated intraspecific performance across trials. Local adaptation was evident for genetic groups tested in their native environments in terms of tree height and, especially, survival. This finding was supported by QST > FST estimates. Additionally, our range‐wide evaluation did not support a general adaptive syndrome by which less reactive groups to ameliorated conditions would be associated with high survival and low growth. In fact, a lack of relationship between mean group differentiation, indicative of genetic adaptation, and predictable group plasticity for height growth suggests different evolutionary trajectories of these mechanisms of phenotypic divergence. Altogether, the existence of predictable adaptive‐trait phenotypic variation for the species, involving both genetic differentiation and plastic effects, should facilitate integrating genomics and environment into decision‐making tools to assist forests to cope with climate change.This article is protected by copyright.
