Phylogenetic Diversity
Phylogenetic diversity” and its abbreviation “PD” have now become popular terms describing a fundamental aspect of biodiversity based on phylogeny. After more than 25 years of work on PD (following
Phylogeny, biogeography, and rates of diversification of New World Astragalus (Leguminosae) with an emphasis on South American radiations.
Two clades of South American species nested within the North American species, implying two separate invasions from North to South America, are supported, reasserting Neo-Astragalus in the growing list of recent rapid radiations of plants, especially in areas with a high physiographic diversity, such as the Andes.
Local adaptation to serpentine and non-serpentine soils in Collinsia sparsiflora
Plants from these six populations at the McLaughlin University of California Natural Reserve represent two distinct, soil-specific ecotypes, raising questions about the relative role of selection and gene flow in promoting genetic differentiation in these contrasting environments.
Foliar micromorphology and anatomy of Ugni molinae Turcz. (Myrtaceae), with particular reference to schizogenous secretory cavities
This is the first study of secretory cavities in Chilean Myrtaceae and micromorphological and anatomical characters are similar to other species of the family.
Spatial phylogenetics of the vascular flora of Chile.
The outcome provides an accurate outline of phylogenetic patterns that can be filled in as more fine-scaled information becomes available, and range-weighted phylogenetic turnover shows high congruence with the main macrobioclimates of Chile.
Phylogenetics of New World Astragalus: Screening of novel nuclear loci for the reconstruction of phylogenies at low taxonomic levels
Four different patterns of phylogenetic diversification occur in the loci sampled from these genomes of Neo-Astragalus species, and one locus has apparently undergone a cryptic duplication, making it very difficult to diagnose.
Genetic diversity of Rhizobium from nodulating beans grown in a variety of Mediterranean climate soils of Chile
R. leguminosarum was identified in almost all soils, was the most genetically diverse, andwas the most common, being documented in soils with pH that ranged between 5.3 and 8.2, and with organic matter content between 2.1 and 4 %.
Endemicity and evolutionary value: a study of Chilean endemic vascular plant genera
This study uses phylogeny-based measures of evolutionary potential (phylogenetic diversity and community structure) to evaluate the evolutionary value of vascular plant genera endemic to Chile, finding an interesting pattern was observed in which areas to the southwest appear to harbor more PD than expected by their generic richness than those Areas to the north of the country.
Modelling the current and future biodiversity distribution in the Chilean Mediterranean hotspot. The role of protected areas network in a warmer future
AIM: Mediterranean Chile is part of the five recognized mediterranean‐type climates in the world and harbours a very rich floral diversity. Climate change has been reported as a significant threat to
Phylogeny-Based Measures of Biodiversity When Data Is Scarce: Examples with the Vascular Flora of Chile and California
The urgency for conserving biodiversity has elicited much research on how to determine its “value” for conservation. The use of phylogenetic diversity (PD) has provided a quantitative framework to
