Out in the cold: genetic variation of Nothofagus pumilio (Nothofagaceae) provides evidence for latitudinally distinct evolutionary histories in austral South America

Current genetic structure of N. pumilio is the result of regional processes which took place during the Tertiary that were enhanced by contemporary local effects of drift and isolation in response to Quaternary climatic cycles.

Phylogeographically concordant chloroplast DNA divergence in sympatric Nothofagus s.s. How deep can it be?

The data suggest that Nothofagus biogeography will be resolved only if thorough phylogeographic analyses and molecular dating methods are applied using distinct genetic markers.

Molecular and fossil evidence disentangle the biogeographical history of Podocarpus, a key genus in plant geography

A calibrated phylogeny of Podocarpus is developed to reconstruct the ancestral areas and potential expansion routes withinPodocarpaceae to analyse divergence between disjunct tropical and temperate forests of South America.

Fine-scale genetic structure of Nothofagus pumilio (lenga) at contrasting elevations of the altitudinal gradient

The fine-scale SGS of Nothofagus pumilio is analyzed in three pairs of sites at contrasting elevations as they may affect population demography, which in turn will affect the spatial genetic structure (SGS).

Genetic Structure and Early Effects of Inbreeding in Fragmented Temperate Forests of a Self‐Incompatible Tree, Embothrium Coccineum

The effects of forest fragmentation were detectable in E. coccineum, but these effects will probably not be detrimental to the viability of remnant populations because small, fragmented populations demonstrated higher levels of gene flow and lower inbreeding than larger stands.

Patterns of genetic variation in tree species and their implications for conservation.

Biodiversity Loss and Conservation in Fragmented Forest Landscapes is the product of over ten years of intensive field research into the changing montane and temperate rainforests of Mexico and South America and helps identify how human disturbance has impacted the biodiversity of all forest types.

Retracing the evolutionary history of Nothofagus in its geo‐climatic context: new developments in the emerging field of phylogeology

Geological evidence from marine sedimentary basins, Andean orogeny, and climatology with molecular dating and statistical phylogeography are combined to infer how geological and climatic processes affected the distribution of lineages in cold‐tolerant Nothofagus species during the Cenozoic.

Morphological and phenological differences in Nothofagus pumilio from contrasting elevations: Evidence from a common garden

While these greenhouse-grown N. pumilio saplings showed heritable differences in plant architectural traits and leafing phenology, it was not clear how the genotypes characteristic of particular elevations would respond to longer growing seasons such as those predicted under global warming.

Identifying Genetic Hotspots by Mapping Molecular Diversity of Widespread Trees: When Commonness Matters.

The hypothesis is that wide-ranging taxa with similar ecological tolerances, yet of phylogenetically independent lineages, have been and currently are shaped by ecological and evolutionary forces that result in geographically concordant genetic patterns that will preserve the evolutionary potential of key habitats and species.
