“…The genetic variation pattern detected in the present study is relatively consistent with the general observation that woody species, especially conifers, maintain most of their variation within populations (Hamrick et al 1992, Müller-Starck 1995, Collignon and Favre 2000, Collignon et al 2002, Kraj 2002. However, the degree of population differentiation (Fst = 0.311) observed in P. asperata was quite large when compared with other conifer species (Petit et al 1995, Zheng and Ennos 1999, Salvador et al 2000, Gomez et al 2003, Prus-Glowacki et al 2003.…”

A survey of allozymic alleles and genetic diversity was conducted for ten natural populations of Picea asperata Mast. originating from the mountains of Southwest China. A total of twenty-seven alleles at seventeen loci were observed. Ten of the loci were found monomorphic. Our results showed that the populations sampled were characterized by low genetic diversity (mean He = 0.096) and a low level of inbreeding (mean Fis = 0.005). The UPGMA tree of genetic relationships indicated that there was significant differentiation among populations. The coefficient of genetic differentiation among populations, based on Fst, equaled 0.311. Such extensive inter-populational differentiation detected in P. asperata could have resulted from allele frequency divergence among populations, particularly, in one population. Introgression from another species, variation in environmental conditions, and differing selection pressures could be some of the factors attributing to significant differences among populations. In addition, our results showed that the geographic and genetic distances were not correlated in the populations of P. asperata. Based on the genetic information obtained, we concluded that monitoring appropriate genetic markers may be an effective means of identifying potential genetic changes occurring during forest tree evolution.

“…Variation in the barcoding loci also evidenced the occurrence of two distinct haplotypes of Taxus baccata in Italy, one shared with other European provenances and a second exclusive of South East Italy. Finally, our results confirmed the genetic diversity existing between Southern and Central Italy provenances of Cupressus sempervirens (Bagnoli et al, 2009), and divergence between Eastern and Western Alps provenances of Picea abies (Collignon & Favre, 2000), as well as between Eastern and Western Mediterranean provenances of P. halepensis (Korol et al, 2002), all previously detected with other molecular markers.

“…During the last 25 years, molecular tools have allowed studies of neutral genetic diversity across regions (Alps for example) and ranges of tree populations (Comps et al 1991;Müller-Starck et al 1991;Zanetto and Kremer 1995;Collignon and Favre 2000;Scotti et al 2006;Tollefsrud et al 2008;Wagner et al 2012). The main results indicated on the one hand that differentiation among populations was extremely low but on the other hand that intraspecific diversity was high (Hamrick et al 1992;Hamrick 2004;Maghuly et al 2006).…”

& Key message Despite variable dynamics of genetic diversification at the different altitudinal levels, strong gene flow tends to standardize larch genetic diversity: the larch forest distributed along the altitudinal gradient can be regarded as a single population. & Context While in forest tree species many studies focus on the structure of the genetic diversity at the natural range and at the forest stand levels, few studies have worked at intermediate levels like the landscape level. & Aims We tried to determine to what degree altitude variation can affect the genetic diversity and the local structure of the genetic diversity of European larch (Larix decidua Miller) at the landscape level. & Methods Using microsatellite markers, we determined the between-and within-plot genetic structure and the spatial genetic structure (SGS) of four altitudinal plots distributed between 1,350 and 2,300 m a.s.l. in a European larch forest located in the French Alps. & Results A homogenous neutral genetic structure was detected along this gradient. The intensity of the SGS was found to be stronger at 2,300 m and decreased at the 2,000-m plot. It was low or non-existent at the 1,700-and 1,350-m altitudinal levels. & Conclusion Our results suggest that the genetic structure observed at the landscape level in this European larch forest was only slightly affected by climatic variation, human activities, or historical events. However, the variation of intensity of the SGS within the altitudinal plots indicates the existence Contribution of the co-authors Maxime Nardin is the PhD student in charge of the study.
