With the aim of detecting new chloroplast variants, we have identified 17 potential cpSSRs motifs from available oak sequences and tested their variability among French oak populations. Six loci were polymorphic at the intraspecific level in Quercus petraea and Q. robur. Moreover, conservation of the primer pairs was checked on a set of 21 forest tree species and they were all shown to work well on several Quercus species, and even within Fagacaea.1 aDEGUILLOUX, M.-F.1 a-LAP, DUMOLIN1 aGIELLY, L.1 aGRIVET, D.1 aPetit, R.J.  uhttps://quercus.myspecies.info/node/4501685nas a2200169   4500008004100000245016600041210006900207260000900276300001400285490000700299520108000306100001501386700002701401700001701428700001501445856005501460       2009                        eng d00aRelative contribution of contemporary pollen and seed dispersal to the effective parental size of seedling population of California valley oak (Quercus lobata N)0 aRelative contribution of contemporary pollen and seed dispersal   c2009  a3967-39790 v183 aFor plant populations, gene movement through pollen and seed dispersal governs the size of local genetic neighbourhoods and shapes the opportunities for natural selection and genetic drift. A critical question is how together these two processes influence the evolutionary dynamics of local populations. To assess the respective contributions of pollen and seed flow, we propose a novel indirect assessment of the separate male and female gametic contributions to total effective parental size (Ne), based on parental correlations estimated via kinship coefficients, that can be applied to data sets that include unambiguous genotypes for male and female gametic contributions. Using the endemic Californian valley oak (Quercus lobata) as our study species, we apply this method to a set of microsatellite genotypes for two distinct ecological sets of naturally recruiting seedlings with acorns attached. We found that the effective numbers of contributing male parents (Nep) exceed effective numbers of female parents (Nem) for seedlings established beneath adult trees (Nep1 aGRIVET, D.1 aRobledo-Arnuncio, J.J.1 aSmouse, P.E.1 aSork, V.L.  uhttp://dx.doi.org/10.1111/j.1365-294X.2009.04326.x02393nas a2200169   4500008004100000245008500041210006900126260000900195300001200204490000700216520185700223100001502080700001502095700001902110700001602129856007802145       2008                        eng d00aConserving the evolutionary potential of California valley oak (Quercus lobata N0 aConserving the evolutionary potential of California valley oak Q  c2008  a139-1560 v173 aAbstract California valley oak (Quercus lobata Nee) is a seriously threatened endemic oak species in California and a keystone species for foothill oak ecosystems. Urban and agricultural development affects a significant fraction of the species’ range and predicted climate change is likely to dislocate many current populations. Here, we explore spatial patterns of multivariate genotypes and genetic diversity throughout the range of valley oak to determine whether ongoing and future patterns of habitat loss could threaten the evolutionary potential of the species by eradicating populations of distinctive genetic composition. This manuscript will address three specific questions: (i) What is the spatial genetic structure of the chloroplast and nuclear genetic markers? (ii) What are the geographical trends in the distribution of chloroplast and nuclear genotypes? (iii) Is there any part of the species’ range where allelic diversity in either the chloroplast or nuclear genomes is particularly high? We analysed six chloroplast and seven nuclear microsatellite genetic markers of individuals widespread across the valley oak range. We then used a multivariate approach correlating genetic markers and geographical variables through a canonical trend surface analysis, followed by GIS mapping of the significant axes. We visualized population allelic richness spatially with GIS tools to identify regions of high diversity. Our findings, based on the distribution of multivariate genotypes and allelic richness, identify areas with distinctive histories and genetic composition that should be given priority in reserve network design, especially because these areas also overlap with landscape change and little degree of protection. Thus, without a careful preservation plan, valuable evolutionary information will be lost for valley oak.1 aGRIVET, D.1 aSork, V.L.1 aWESTFALL, R.D.1 aDavis, F.W.  uhttp://www.blackwell-synergy.com/doi/abs/10.1111/j.1365-294X.2007.03498.x
