Only a day's drive south of the U.S.-Mexico border, a tropical deciduous forest opens up a world of exotic trees and birds that most people associate with tropical forests of more southerly latitudes. Like many such forests around the world, this div

The endemic Hawaiian silversword and lobeliad lineages, which are two of the world’s premier examples of plant adaptive radiation, exemplify the severity of the threats confronting the Hawaiian flora, especially the threats posed by alien species.

Author(s): Blonder, B; Baldwin, BG; Enquist, BJ; Robichaux, RH | Abstract: The Hawaiian silversword alliance is a spectacular example of plant adaptive radiation. The lineage includes 33 species in three endemic genera (Argyroxiphium, Dubautia and Wi

Native plant species that have lost their mutualist partners may require non-native pollinators or seed dispersers to maintain reproduction. When natives are highly specialized, however, it appears doubtful that introduced generalists will partner ef

The impact of gene flow and population size fluctuations in shaping genetic variation during adaptive radiation, at both the genome-wide and gene-specific levels, is very poorly understood. To examine how historical population size and gene flow patt

Mechanisms of reproductive isolation during plant speciation are often unclear because distinct species often experience high levels of gene flow and hybridization. Adaptive radiations such as the Hawaiian silversword alliance (HSA) provide unique op

Genome-wide duplication (polyploidization) is prevalent in a large number of eukaryotic organisms and is particularly widespread in flowering plants. Polyploid species appear to vary from their diploid progenitors in a variety of ecologically importa

Reintroduction of populations of endangered species is a challenging task, involving a number of environmental, demographic and genetic factors. Genetic parameters of interest include historical patterns of genetic structure and gene flow. Care must

The Mauna Kea silversword, Argyroxiphium sandwicense ssp. sandwicense, has experienced both a severe population crash associated with an increase in alien ungulate populations on Mauna Kea, and a population bottleneck associated with reintroduction.
