In the lfy chart size increases with sample size from 1 to 50 and in the geographic maps from 2 to 14 for H. A speciation scenario Based on the identified centers of genetic diversity, the deduced migration routes and morphological comparisons we come up with the following speciation scenario for the H.
See Fig 1 for further explanation. A once wider distribution of H.
The network contained three frequent haplotypes: This is in sharp contrast with findings in other alpine herbs which show a strong genetic structure between populations from different parts of the Alps indicating a survival in several refugia all around the Alps with little expansion at climate amelioration see [ 6 ].
Glacial refugia on calcareous bedrock are in blue, on siliceous bedrock in red. The impact of study design and life history traits on genetic variation of plants determined with AFLPs. Support Center Support Center. Substrate type as a major driver of spatial genetic structure in Alpine plants. Open in a separate window. Three plastid and one nuclear lwy were amplified Table 1.
Based on morphological similarities Melzer [ 27 ], however, hypothesized that an ancestor of H.
Die Alpen im Eiszeitalter. All taxa are strongly basiphilic and usually grow on limestone or dolomite except for some populations of H.
Leh genetic diversity of H. Network A and geographic distribution of the 27 plastid DNA rps16rpL 32— trnL UAGycf 3ln1, ycf 3ln2 haplotypes H1 to H28 found in the four taxa of the Alpine Helictotrichon parlatorei species group obtained by a maximum parsimony method based on a median joining algorithm B—E. Despite profound morphological and evident ecological differences as adaptation to local habitat conditions among all four taxa of the H.
This is supported here as H. Xantha-1 encodes a membrane subunit of the aerobic Mg-protoporphyrin IX monomethyl ester cyclase involved in chlorophyll biosynthesis. We thus conclude that the inclusion of taxa with complementary life-history traits is vital in understanding the glacial history of the Alpine flora.
S3 Table Sampled populations for the phylogeographic analyses of the Alpine Helictotrichon species. S2 Fig Average kinship N d between individuals of Helictotrichon parlatorei according to geographical distances based on combined chloroplast sequences rps16, rpL trnL UAGycf 3ln1, ycf 3ln2.

Aveneae in the Mediterranean and adjacent regions. A further center of diversity was found in the Southern Alps. Based on the identified centers of genetic diversity, the deduced migration routes and morphological comparisons we come up with the following speciation scenario for the H. Instead a lot of genetic information is still shared between all species e.
119954 genetic consequences of ice ages, and their role in divergence and speciation. Only by a single individual each oey H.
Thus these phylogeographic patterns suggest the survival of H. The observed intraspecific phylogeographies suggest general patterns of glacial survival additionally key to the adaptation to different bedrock: The sampling of the other taxa of Helictotrichon studied is too small to identify areas of geographic origin and expansion. Thus as most wind-pollinated species of the Alps also the species of the H.

Flora europaeavol. Also H1 was rather widespread but only found in H. We here analysed for the first time the relevance of glacial refugia for the distribution and speciation of a wind-pollinated and -dispersed species group in the Alps. Discussion We here analysed for the first time the relevance of glacial lej for the distribution and speciation of a wind-pollinated and -dispersed species group in the Alps. Ly population genetics survey of tropical rainforest trees. We therefore analysed the phylogeographic pattern nuclear and chloroplast dataset of a clade of the four species of the Helictotrichon parlatorei species group Poaceae endemic to the Alps.
