Estimating connectivity is key for maintaining population viability for pond-breeding amphibians, especially in areas where habitat alterations occur. Here, we used genetic data (microsatellites) to estimate connectivity of marbled salamanders, Ambys

Polyploids are thought to harbor more genetic diversity than diploids, despite the genetic bottleneck they experience upon formation. Identifying the means by which polyploids become more genetically variable can advance our understanding of the evol

‘Ecogeographic isolation’ describes the combined role of ecology and geography as a reproductive barrier, and an important component in speciation. Evidence increasingly shows that this form of isolation is important for maintaining the genetic i

Using likelihood-based variable selection models, we determined if positive selection was acting on 523 EST sequence pairs from two lineages of sunflower and lettuce. Variable rate models are generally not used for comparisons of sequence pairs due t

Chloroplast and nuclear DNA sequence variation among populations and species was used to examine the phylogenetic history and hybridization of the North American Houstonia lineage. The ancestral species in the lineage do not show evidence of hybridiz

Premise of the study: Microsatellites were developed for the native, perennial herbs Houstonia longifolia and H. purpurea to establish rates and patterns of hybridization among these and other closely related lineages within the genus. Methods

Polyploidy, or genome doubling, is a common mechanism in the evolution of plants. This genome duplication can rapidly lead to genomic changes between ploidy levels. In particular, allopolyploids that result from interspecific hybridization can show a

The framework for modern studies of speciation was established as part of the Neo-Darwinian synthesis of the early twentieth century. Here we evaluate this framework in the light of recent empirical and theoretical studies. Evidence from experimental

More than 67,000 expressed sequence tags (ESTs) have recently been generated for sunflower (Helianthus), including 44,000 from cultivated confectionery (RHA280) and oilseed (RHA801) lines of Helianthus annuus and 23,000 from drought- and salt-toleran

Nuclear and chloroplast DNA sequence variation was used to infer evolutionary relationships within and among members of Houstonia (Rubiaceae) and other closely related genera in North America. Sequences from the internal transcribed spacer (ITS) of t
