Sixteen of these markers are newly developed and we report primer sequences and amplification conditions here. Twelve of the thirty (40.0%) red oak markers amplified and were polymorphic in the European white oaks Quercus petraea and Quercus robur. Five of the thirty loci (16.7%) also amplified and four were polymorphic in the phylogenetically distant Chinese chestnut (Castanea mollissima). These markers should bewidely applicable to genetic studies of Quercus and other members of the Fagaceae.1 aALDRICH, P.R.1 aJAGTAP, M.1 aMICHLER, C.H.1 aROMERO-SEVERSON, J.  uhttps://quercus.myspecies.info/node/4102042nas a2200169   4500008004100000245014000041210006900181260000900250300000900259490000700268520147700275100001801752700001701770700001801787700002401805856004301829       2003                        eng d00aWhole-tree silvic identifications and the microsatellite genetic structure of a red oak species complex in an Indiana old-growth forest0 aWholetree silvic identifications and the microsatellite genetic   c2003  a22280 v333 aThe red oaks (Quercus section Lobatae) include important timber species, but we know little about theirgene pools. Red oak species can be difficult to identify, possibly because of extensive interspecific hybridization, although most evidence of this is morphological. We used 15 microsatellite loci to examine the genetic composition of a red oak community in 20.6 ha of an Indiana old-growth forest. The community included northern red oak (Quercus rubra L.), Shumard oak (Quercus shumardii Buckl.), and pin oak (Quercus palustris Muenchh.). Species were identified using whole-tree silvic characters, the approach most often implemented by foresters. We found high genetic diversity within species but limited genetic differences between species. Phenetic clustering showed that Q. rubra and Q. shumardii were more genetically similar than either was to Q. palustris, but a neighbor-joining tree revealed that individuals of the different species did not resolve into single-species clusters. We identified four mixed-species subpopulations using Structure, a computer program based on Monte Carlo simulation. The three largest groups are consistent with the following biological interpretations: (i) pure Q. rubra, (ii) Q. rubra, Q. shumardii, and their hybrids, and (iii) Q. rubra, Q. shumardii, Q. palustris, and their hybrids. We discuss the implications of these findings for the whole-tree silvic approach to selection and for management of the red oak gene pool.1 aALDRICH, P.R.1 aParker, G.R.1 aMICHLER, C.H.1 aROMERO-SEVERSON, J.  uhttps://quercus.myspecies.info/node/4601821nas a2200157   4500008004100000245009700041210006900138260000900207300001200216490000800228520131000236100001801546700001301564700002401577856006201601       2009                        eng d00aBiogeographical Distribution of Chloroplast Diversity in Northern Red Oak (Quercus rubra L.)0 aBiogeographical Distribution of Chloroplast Diversity in Norther  c2009  a134-1450 v1613 aWe mapped the biogeographical distribution of chloroplast haplotypes in northern red oak (Quercus rubra L.) to test the hypotheses that the founder effects during postglacial migration will result in a latitudinal gradient of haplotype diversity with exhaustion of haplotype richness at the extreme northern edge of the range. PCR-RFLP markers for 23 populations of Q. rubra in old growth and minimally disturbed forests across 13,000 km2 of the contemporary range revealed only four of the five haplotypes detected previously at 12 sites in Indiana. The four northernmost populations were fixed for either haplotype I or haplotype II, the two most common haplotypes. Haplotype richness declined poleward, but the biogeographical pattern of 829 haplotypes across the 35 sites did not clearly indicate postglacial migration routes along latitudinal gradients from the southern edges of the study area. Although Q. rubra and the European white oak Q. robur L. are both early successional species that recolonized vast areas as the glaciers retreated, the data indicate that Q. rubra has lower chloroplast haplotype richness, suggesting that the population dynamics of Q. rubra prior to or during Pleistocene climate fluctuations may have differed from the population dynamics of the European white oak taxa.1 aBIRCHENKO, I.1 aFENG, Y.1 aROMERO-SEVERSON, J.  uhttp://www.bioone.org/doi/abs/10.1674/0003-0031-161.1.13400616nas a2200157   4500008004100000245012500041210006900166260000900235300001200244490000700256520010300263100001300366700001200379700002400391856004300415       2008                        eng d00aHeterogeinity and spatial autocorrelation for chloroplast haplotypes in three old growth populations of Northern Red Oak0 aHeterogeinity and spatial autocorrelation for chloroplast haplot  c2008  a212-2200 v573 aIn eastern North America, evidence for cryptic northern refugia could contribute to resolving Reid1 aFENG, Y.1 aSUN, W.1 aROMERO-SEVERSON, J.  uhttps://quercus.myspecies.info/node/16
