PREMISE OF THE STUDY The opuntias (nopales, prickly pears) are not only culturally, ecologically, economically, and medicinally important, but are renowned for their taxonomic difficulty due to… Expand
Cytogeography of the Humifusa clade of Opuntia s.s. Mill. 1754 (Cactaceae, Opuntioideae, Opuntieae): correlations with pleistocene refugia and morphological traits in a polyploid complex
Abstract Ploidy has been well studied and used extensively in the genus Opuntia to determine species boundaries, detect evidence of hybridization, and infer evolutionary patterns. We carried out… Expand
High proportion of cactus species threatened with extinction
A high proportion of plant species is predicted to be threatened with extinction in the near future. However, the threat status of only a small number has been evaluated compared with key animal… Expand
The first complete plastid genomes of Melastomataceae are highly structurally conserved
Background In the past three decades, several studies have predominantly relied on a small sample of the plastome to infer deep phylogenetic relationships in the species-rich Melastomataceae. Here,… Expand
Miscellaneous Chromosome Numbers in Opuntieae Dc. (Cactaceae) with a Compilation of Counts for the Group
Abstract: Chromosome counts of members of the Opuntieae were carried out to further our understanding of ploidal levels, species boundaries, and evolutionary patterns within this group of stem… Expand
From cacti to carnivores: Improved phylotranscriptomic sampling and hierarchical homology inference provide further insight into the evolution of Caryophyllales.
PREMISE OF THE STUDY The Caryophyllales contain ~12,500 species and are known for their cosmopolitan distribution, convergence of trait evolution, and extreme adaptations. Some relationships within… Expand
CAREX BREVICULMIS (CYPERACEAE), NEW TO THE FLORA OF NORTH AMERICA
Carex breviculmis, a species native to Asia, Australia, and the Indian Subcontinent, was collected early in 2007 in Lauderdale County, Mississippi, U.S.A., at two areas in the city of Meridian.… Expand
Are polyploids really evolutionary dead-ends (again)? A critical reappraisal of Mayrose et al. ().

- 1 June 2014
Throughout the past century, hybridization and polyploidization have variously been viewed as drivers of biodiversity (e.g. Arnold, 1997) or evolutionary noise, unimportant to the main processes of… Expand
Synthetic polyploids of Tragopogon miscellus and T. mirus (Asteraceae): 60 Years after Ownbey's discovery.
In plants, polyploidy has been a significant evolutionary force on both recent and ancient time scales. In 1950, Ownbey reported two newly formed Tragopogon allopolyploids in the northwestern United… Expand
Spatial Phylogenetics of Florida Vascular Plants: The Effects of Calibration and Uncertainty on Diversity Estimates

- 8 December 2018
Recent availability of biodiversity data resources has enabled an unprecedented ability to estimate phylogenetically based biodiversity metrics over broad scales. Such approaches elucidate ecological… Expand
