Unexpected ancestry of Populus seedlings from a hybrid zone implies a large role for postzygotic selection in the maintenance of species

Lindtke, Dorothea ; Gompert, Zachariah ; Lexer, Christian ; Buerkle, C. Alex

In: Molecular Ecology, 2014, p. –

In the context of potential interspecific gene flow, the integrity of species will be maintained by reproductive barriers that reduce genetic exchange, including traits associated with prezygotic isolation or poor performance of hybrids. Hybrid zones can be used to study the importance of different reproductive barriers, particularly when both parental species and hybrids occur in close spatial...

Recombinant hybrids retain heterozygosity at many loci: new insights into the genomics of reproductive isolation in Populus

Lindtke, Dorothea ; Buerkle, C. Alex ; Barbará, Thelma ; Heinze, Berthold ; Castiglione, Stefano ; Bartha, Denes ; Lexer, Christian

In: Molecular Ecology, 2012, p. -

The maintenance of species barriers in the face of gene flow is often thought to result from strong selection against intermediate genotypes, thereby preserving genetic differentiation. Most speciation genomic studies thus aim to identify exceptionally divergent loci between populations, but divergence will be affected by many processes other than reproductive isolation (RI) and speciation....

Genomic admixture analysis in european Populus spp. reveals unexpected patterns of reproductive isolation and mating

Lexer, Christian ; Joseph, Jeffrey A. ; Loo, Marcela van ; Barbará, Thelma ; Heinze, Berthold ; Bartha, Denes ; Castiglione, Stefano ; Fay, Michael F. ; Buerkle, C. Alex

In: Genetics, 2010, vol. 186, p. 699–712

Admixture between genetically divergent populations facilitates genomic studies of the mechanisms involved in adaptation, reproductive isolation and speciation, including mapping of the loci involved in these phenomena. Little is known about how pre- and postzygotic barriers will affect the prospects of 'admixture mapping' in wild species. We have studied 93 mapped genetic markers...

Admixture as the basis for genetic mapping

Buerkle, C. Alex ; Lexer, Christian

In: Trends in Ecology & Evolution, 2008, vol. 23, no. 12, p. 686-694

Genetic mapping in natural populations is increasing rapidly in feasibility and accessibility. As with many areas in genetics, advances in molecular techniques and statistics are drastically altering how we can investigate inheritance in wild organisms. For ecology and evolution, this is particularly significant and promising, because many of the organisms of interest are not amenable to...
