Phylogenetic evaluation of Xylothamia, Gundlachia, and related genera (Asteraceae, Astereae) based on ETS and ITS nrDNA sequence data.
TLDR
The present 3' ETS and ITS nrDNA gene phylogenies yielded the unexpected result that Xylothamia is polyphyletic, which means species within its circumscription are placed into two well-supported evolutionary lineages with other genera of Astereae.
TECHNIQUES FOR IMPROVING THE QUALITY AND QUANTITY O F DNA EXTRACTED FROM HERBARIUM SPECIMENS
There is a need to modify DNA extraction methods to obtain amplifiable DNA from herbarium specimens that are relatively old –– we explored several methods to improve both quality and quantity of DNA
Molecular phylogeny of Ericameria (Asteraceae, Astereae) based on nuclear ribosomal 3' ETS and ITS sequence data
TLDR
Ericameria, Pentachaeta, Rigiopappus and Tracyina are resolved in a monophyletic group distinct from Chrysothamnus, Xylothamia, and representatives of the Solidago lineage.
The Influence of Agricultural Abandonment and the Abiotic Environment on the Vegetation Communities of a Suburban Deciduous Forest
ABSTRACT  Length of time since agricultural abandonment, variations in topography and soil, and forest fragmentation associated with suburban development can influence dominant vegetation and foster
Edges, exotics and deer: the seed bank of a suburban secondary successional temperate deciduous forest
TLDR
Reliance on the soil seed bank as a passive restoration strategy will be insufficient for restoring a mature secondary successional suburban forest community, however, a suite of shade-tolerant exotic shrubs and vines that are of concern to management do not appear to use the seed bank, indicating that targeted removal of these species may be successful.
Molecular Phylogeny of Chrysothamnus and Related Genera (Asteraceae, Astereae) Based on Nuclear Ribosomal 3′ ETS and ITS Sequence Data
TLDR
The results indicate that Chrysothamnus as traditionally perceived is polyphyletic, with species placed in four well-supported lineages, and some of the morphological features used to delimit these genera may be the product of convergence, thus diminishing their value for phylogenetic reconstruction.
Genetic Variation and Population Structure of Arabidopsis lyrata ssp. lyrata (Brassicaceae) along the Eastern Seaboard of North America
Abstract Arabidopsis lyrata ssp. lyrata is widespread but edaphically restricted, which suggests that the dispersal ability and level of genetic exchange among populations might be limited. We
NESTOTUS AND TOIYABEA, TWO NEW GENERA OF ASTERACEAE: ASTEREAE FROM THE WESTERN UNITED STATES AND CANADA
Nestotus is described as a new ditypic genus from the western United States and the Yukon Territory, Canada, to accommodate Stenotus macleanii (Brandegee) A. Heller and Stenotus stenophyllus (A.
