Complex bioclimatic and soil gradients shape leaf trait variation in Embothrium coccineum (Proteaceae) among austral forests in Patagonia

Las variables climaticas biologicamente importantes y the disponibilidad of nutrientes in el suelo son utiles para predecir el tamano y estructura of the hoja de E. coccineum, y el patrones observados en SLA podrian deberse a valores bajos de esta variable en hojas.

How do cold-sensitive species endure ice ages? Phylogeographic and paleodistribution models of postglacial range expansion of the mesothermic drought-tolerant conifer Austrocedrus chilensis.

The evidence suggests that in contrast to cold-tolerant tree taxa with the capacity to fast-track postglacial warming thanks to local refugia, cold-sensitive species might have undergone long-distance range expansion, lagging behind progressive climate change throughout the Holocene.

Effects of crossing distance and genetic relatedness on pollen performance in Alstroemeria aurea (Alstroemeriaceae).

The existence of distance-dependent prezygotic barriers in self-compatible Alstroemeria aurea, a clonal herb native to temperate forests of the southern Andes, is reported and it is proposed that the existence of prezyGotic barriers might contribute to the high degree of genetic mixing exhibited by some clonal species.

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.

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.

Ecological niche modeling, niche overlap, and good old Rabinowitz’s rarities applied to the conservation of gymnosperms in a global biodiversity hotspot

The approach showed that there are unprotected suitable areas for native key species at high risk in PTF, suggesting that integrating habitat-suitability models of multiple species, types of rarity, and niche overlap, can be a handy tool to identify potential conservation areas in global biodiversity hotspots.

Genetic Diversity and Structure in Austrocedrus chilensis Populations: Implications for Dryland Forest Restoration

Geographic patterns of genetic variation in Austrocedrus chilensis, a dominant conifer of the steppe-forest ecotone in the eastern Andes, are analyzed to examine its potential for restoration and suggest relatively small, inbred yet genetically diverse northern populations should be the subject of passive restoration efforts.

Genetic variation in the widespread Embothrium coccineum (Proteaceae) endemic to Patagonia: effects of phylogeny and historical events

The present study highlights the importance of phylogenetic imprinting, life-history traits and historical events driving genetic diversity patterns in this widespread Proteaceae from southern South America, which seems to show clear historical tracks of northern range expansion from southern refugia.

Patterns of isozyme variation as indicators of biogeographic history in Pilgerodendron uviferum (D. Don) Florín

The presence of centres of genetic diversity, together with the lack of a significant correlation between genetic and geographical distances and the absence of geographical patterns of allelic frequencies at most analysed alleles, may indicate that Pilgerodendron did not advance southward after the last glaciation, but spread from several surviving populations in ice‐free areas in Patagonia instead.

Adaptive and neutral variation of the resprouter Nothofagus antarctica growing in distinct habitats in north-western Patagonia

Isozyme evidence indicates a great deal of within-population genetic diversity which is maintained by outcrossing and significant among-site divergence (F-ST = 18%) that reflects limited gene flow.
