“…Like many tree species, neutral genetic variation in lodgepole pine is mostly partitioned within populations (Yang et al 1996;Hamrick 2004). Studies of growth response, however, have found significant patterns of local adaptation and divergence in trait means among populations (Yang et al 1996;Rehfeldt et al 1999;Wu & Ying 2004). Because the environment is sufficiently heterogeneous to maintain divergence between populations in the presence of gene flow, lodgepole pine conforms to the assumptions of the gene flow/environmental heterogeneity hypothesis described above.…”

“…This experiment was established by Keith Illingworth and maintained by the British Columbia Forest Service; the details are described more thoroughly in other papers (Rehfeldt et al 1999;Wu & Ying 2004). Basic experimental design was as follows: seeds were collected from ca 15 different trees in each population (over an area of ca 1 km 2 ) and bulked according to their population of origin (Alvin Yanchuk 2005, personal communication).…”

“…To test this prediction, we studied patterns of genetic variation within populations of lodgepole pine (Pinus contorta) using previously collected data from a long-term common garden experiment (Rehfeldt et al 1999) and compared these with quantitative estimates of environmental heterogeneity. Lodgepole pine is a long-lived, highly outcrossed conifer (Yeh & Layton 1979) with an extensive range spanning climatically heterogeneous mountain environments and relatively homogenous valleys and plateaus from Baja California to the Yukon Territories and Alaska.…”

Genetic variation is of fundamental importance to biological evolution, yet we still know very little about how it is maintained in nature. Because many species inhabit heterogeneous environments and have pronounced local adaptations, gene flow between differently adapted populations may be a persistent source of genetic variation within populations. If this migration-selection balance is biologically important then there should be strong correlations between genetic variance within populations and the amount of heterogeneity in the environment surrounding them. Here, we use data from a long-term study of 142 populations of lodgepole pine (Pinus contorta) to compare levels of genetic variation in growth response with measures of climatic heterogeneity in the surrounding region. We find that regional heterogeneity explains at least 20% of the variation in genetic variance, suggesting that gene flow and heterogeneous selection may play an important role in maintaining the high levels of genetic variation found within natural populations.

“…Testing seedlings survival in the field, 5 years after planting, aimed at indicating the particular population and half-sib lines which are promising for the transfer into new habitats in conditions that are similar to the conditions prevailing in Drinić. The research done on the adaptive potential of tested populations and half-sib populations provides guidance to potential sources of reproductive materials which are able to withstand the impact of the environment and suitable for the transfer of reproductive material (Rehfeldt et al, 1999;Rehfeldt, 2004;O'Brien et al, 2007;Vitt et al 2010;Ukrainetz et al 2011). …”

This paper presents the results of survival in progeny tests in the Republic of Srpska (Bosnia and Herzegovina). Four progeny tests of Norway spruce on sites: Drinić, Derventa, Nevesine and Srebrenica were established on the territory of the Republic of Srpska in 2009. These progeny tests consist of six populations: Han Pijesak 1 and 2, Foča, Potoci, Olovo and Kneževo. The total number of half-sib lines was 36.In this paper, the data collected during 2014 were analyzed and they refer to the survival of Norway spruce seedlings in the progeny test in Drinić. The data were processed in order to determine which populations and half-sib lines are best adapted to ecological conditions of Drinić area.The results indicate a significant variability of survival among the tested populations and half-sib lines. They also indicate a higher adaptability of population originating from geographically more distant provenances from progeny test, in comparison with closer populations. The results can be used for the purpose of transferring the spruce reproductive material from Bosnia and Herzegovina to Drinić area, as well as the sites which are characterized by similar ecological conditions.

“…Similarly, this method can be used to assess how adaptive diversity is partitioned throughout the range of a species, and whether there are high levels of variation within and/or between populations. This approach has been used to examine adaptation and the effects of climate change on the pine trees Pinus contorta and Pinus sylvestris (Rehfeldt et al, 1999; and to assess plasticity in Pinus ponderosa (Maherali et al, 2002). While this is the most robust approach to assessing physiological adaptive capacity, it tends to be expensive and time-consuming, and may therefore be an unacceptable option for all but the most highly-valued species.…”
