    ..e., for species groups or the entire genus), environmental correlations were absent. This could mostly be attributed to the superimposition of life-form changes and phylogenetic constraints, which conceal ecogeographical correlations...

    Sabine S Jakob
    Leibniz Institute of Plant Genetics and Crop Science IPK, D 06466 Gatersleben, Germany
    Mol Biol Evol 23:1602-12. 2006
    ..We conclude that the described phenomena are not restricted to Hordeum and that the knowledge of the chloroplast relationships within a genus is indispensable to prevent misinterpretation of phylogeographic data within single species...

    Mol Ecol 16:1713-27. 2007
    ..The extant sympatric occurrence of H. marinum and H. gussoneanum 2x in the Mediterranean region is interpreted as a result of secondary contact after fast Holocene range expansion out of different ice age refugia...

    Sabine S Jakob
    Leibniz Institute of Plant Genetics and Crop Research IPK, Gatersleben, Germany
    Mol Biol Evol 26:907-23. 2009
    ..As the Hordeum species are characteristic taxa of different steppe habitats, we speculate that the Patagonian steppe might be an old vegetation unit occurring for up to 4.5 My in southern South America...
