EVOLUTION OF THE MAGNITUDE AND TIMING OF INBREEDING DEPRESSION IN PLANTS
TLDR
The hypothesis that most early acting inbreeding depression is due to recessive lethals and can be purged through inbreeding, whereas much of the late‐acting inbreeding depressions are due to weakly deleterious mutations and is very difficult to purge, even under extreme inbreeding is supported. Expand
A DNA barcode for land plants
TLDR
The 2-locus combination of rbcL+matK will provide a universal framework for the routine use of DNA sequence data to identify specimens and contribute toward the discovery of overlooked species of land plants. Expand
Practical Pollination Biology
Evaluating approaches to the conservation of rare and endangered plants
TLDR
Evaluating approaches to the conservation of rare and endangered plants and their impacts on threatened and endangered species in the wild is a good place to start. Expand
Multiple Multilocus DNA Barcodes from the Plastid Genome Discriminate Plant Species Equally Well
TLDR
Resolution to the contentious debate on plant barcoding should involve increased attention to practical issues related to the ease of sequence recovery, global alignability, and marker redundancy in multilocus plant DNA barc coding systems. Expand
Are plant species inherently harder to discriminate than animal species using DNA barcoding markers?
TLDR
The results using common metrics demonstrate that the number of species supported as monophyletic using barcoding markers is higher in animals than plants, even after controlling for the amount of parsimony‐informative information per species. Expand
Autopolyploidy in angiosperms: Have we grossly underestimated the number of species?
TLDR
The traditional view of plant autopolyploids as mere cytotypes is reassessed, and it is suggested that they be considered distinct species and also provide a system for naming them. Expand
Genome duplication and the evolution of physiological responses to water stress.
TLDR
The different physiological tolerances and distribution of diploid and tetraploid C. angustifolium are unlikely to be caused solely by genome duplication, and the enhanced ability of Tetraploids to survive water stress likely evolved after polyploidization. Expand
Constraints on polyploid evolution: a test of the minority cytotype exclusion principle

TLDR
These results provide the first experimental test of frequency–dependent fitness in diploid–polyploid mixtures and suggest an important role for more gradual, population processes governing the evolution of polyploidy in natural populations. Expand
The role of triploid hybrids in the evolutionary dynamics of mixed-ploidy populations
TLDR
The effects of triploids on autotetraploid evolution is evaluated using computer simulations and by synthesizing research on the evolutionary dynamics of mixed-ploidy populations in Chamerion angustifolium (Onagraceae). Expand
