The comparisons of genetic diversity among species in the same area each revealed marked differences. Material and methods Species description The four alpine endemics of the H. They are characterized by an axis of the floret disarticulating only above the glumes apomorphic character and not below each floret as found in the remaining species of the genus [ 16 ].

All taxa are strongly basiphilic and usually grow on limestone or dolomite except for some populations of H. Measuring and testing genetic differentiation with ordered versus unordered alleles. The level of population structure G ST in H.

In the network chart size increases with sample size from 1 to 50 and in the geographic maps from 2 to 14 for H. Xantha-1 encodes a membrane subunit of the aerobic Mg-protoporphyrin IX monomethyl ester cyclase involved in chlorophyll biosynthesis.

Here climatic fluctuations caused significant population migrations and fragmentations or even extinctions [ 1 — 3 ] and thereby repeatedly provoked allopatric speciation [ 45 ]. Unfortunately, a further sister group support for leu geographic placement of its origin is still not available as only the monophyly of the H.

The eastern and northern populations exhibited rather low haplotype diversities. See Fig 1 for further explanation. Acknowledgments We are grateful to the curators of the following herbaria for the loan of herbarium specimens: Three plastid and one nuclear marker were amplified Table 1.


The species thus escape the more stressful conditions of lower temperature, higher precipitation and longer snowcover at higher altitude [ 46 ]. Each species occupies a characteristic habitat: The sampling of the other taxa of Helictotrichon studied is too small to identify areas of geographic origin and expansion.

Also Ely was rather widespread but only found in H. Plant material and taxon sampling We sampled individuals of Helictotrichon 98 Helictotrichon parlatorei11 Ldy.

The absence of congruent gene pools indicates effective dispersal of this species across its entire distribution area—largely unaffected by the alpine topography. Detailed morphological 19945 indicate the presence of morphological intermediates between Leg. The entire Eastern Alps are overall rather genetically depauperate indicating a recent colonization via efficient long distance wind dispersal.

The shortest haplotype network needed seven mutations. Consequently, Helictotrichon parlatorei is the only widespread leey in the Alps today, which might be due to a higher cold resistance of this species [ 16 ].

The identity of its sister clade and the relationships among species within the H. Among the species of the H. A similar lack of genetic differentiation across large distances can repeatedly be found in phylogeographic studies of other wind-pollinated grass species [ 38 — 40 ]. Only in the plastid genome, which directly reflects seed dispersal due to its predominantly maternal inheritance [ 41 ], the West-East disjunction in the Alps becomes a little apparent by an accumulation of numerous rare haplotypes solely in the Western Alps producing a considerable peak in the N d curve at km S2 Fig.


There are no genetic differences between di- and ely in H.

Genome evolution in alpine oat-like grasses through homoploid hybridization and polyploidy. Allopolyploid origin of Mediterranean species in Helictotrichon Poaceae and its consequences for karyotype repatterning and homogenization of rDNA repeat units.

Table 2 Number of individuals per taxon bearing the haplotypes of the nuclear marker At in the Helictotrichon parlatorei species group. Starting in the Western Alps we thus hypothesize a consecutive sympatric ecological speciation of H. Thus these phylogeographic patterns suggest the survival of 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. Here differences in biological traits between species might play a role [ 4748 ], however, to confirm this more detailed ecological studies would be necessary in the Helictotrichon species.

Cambridge University Press; 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 ].
