    Decoupled evolution of foliar freezing resistance, temperature niche and morphological leaf traits in Chilean Myrceugenia
    (2014) Perez, Fernanda; Hinojosa, Luis F.; Ossa, Carmen G.; Campano, Francisca; Orrego, Fabiola
    1. Phylogenetic conservatism of tolerance to freezing temperatures has been cited to explain the tendency of plant lineages to grow in similar climates. However, there is little information about whether or not freezing resistance is conserved across phylogenies, and whether conservatism of physiological traits could explain conservatism of realized climatic niches. Here, we compared the phylogenetical lability of realized climatic niche, foliar freezing resistance and four morphological leaf traits that are generally considered to be adaptations to frost resistance in the Chilean species of Myrceugenia, which grows in a wide range of habitats.

    GENETIC EVIDENCE FOR GLACIAL REFUGIA OF THE TEMPERATE TREE EUCRYPHIA CORDIFOLIA (CUNONIACEAE) IN SOUTHERN SOUTH AMERICA
    (2012) Segovia, Ricardo A.; Perez, Maria F.; Hinojosa, Luis F.
    Premise of the study: The temperate forests of southern South America were greatly affected by glaciations. Previous studies have indicated that some cold-tolerant tree species were able to survive glacial periods in small, ice-free patches within glaciated areas in the Andes and in southern Patagonia. Here we asked whether populations of the mesothermic species Eucryphia cordifolia also were able to survive glaciations in these areas or only in unglaciated coastal areas.
