Abstract Public lands across the United States are managed for multiple uses, resources, and values ranging from energy development to rare plant conservation. Intensified energy development and other land use changes across the Southwestern United S

Boechera is a model genus that is of particular interest for understanding apomixis due to the presence of numerous apomictic diploid lineages that are tightly correlated with hybridisation events. Boechera includes many narrowly distributed endemics

Taxonomic studies in Heuchera from the southern Intermountain Region in Arizona and New Mexico, U. S. A. have revealed two new species from Heuchera section Heuchera: Heuchera soltisii (Heuchera subsect. Parvifoliae) and Heuchera inconstans (H. subse

Hybrid speciation is relatively common in plants compared to other well-studied groups. Polyploidy and apomixis are strongly associated with hybrid speciation, presumably due to the opportunities they provide for both reestablishing reproductive func

Boechera (Brassicaceae) is a diverse genus of ±70 sexual diploid species and numerous apomictic hybrids concentrated in western North America. It is the largest genus in tribe Boechereae, which also includes seven other small genera. Boechera is clo

Gametophytic apomixis is a common form of asexual reproduction in plants. Virtually all gametophytic apomicts are polyploids, and some view polyploidy as a prerequisite for the transition to apomixis. However, any causal link between apomixis and pol

Premise of the study: The evolutionary history of Leucaena has been impacted by polyploidy, hybridization, and divergent allopatric species diversifi cation, suggesting that this is an ideal group to investigate the evolutionary tempo of polyploid

The relationships and taxonomy of the genus Thysanocarpus (Brassicaceae) are reassessed based on molecular phylogenetic analyses of nuclear ribosomal (ITS) and chloroplast (trnh-F) sequences and a critical re-examination of morphology and nomenclatur

The time needed for hand grinding and the cost of commercially available extraction kits remain to be the major limitations in plant DNA extraction for many researchers. We present inexpensive techniques for (i) simultaneously machine grinding large

Equipping the standard plastic cup trap, also known as the CC trap, with lime-green light-emitting diodes (LED-plastic cup trap) increased its efficacy for catching Bemisia tabaci by 100%. Few Eretmocerus eremicus Rose and Zolnerowich and Encarsia fo
