Studies of pollen development and function (Heslop-Harrison, 1971), along with correlations
between pollen morphology, incompatibility system, and mode of pollination (DeNettancourt …

We investigated Viburnum phylogeny using separate and combined analyses of DNA
sequence data from two chloroplast and three nuclear loci. Separate analyses of nuclear …

Background The chloroplast genes mat K and rbc L have been proposed as a “core” DNA
barcode for identifying plant species. Published estimates of successful species …

The deciduous habit of northern temperate trees and shrubs provides one of the most
obvious examples of convergent evolution, but how did it evolve? Hypotheses based on the …

The Forest of the Lacandon Maya: An Ethnobotanical Guide, with active links to audio-video
recordings, serves as a comprehensive guide to the botanical heritage of the northern …

Phylogenetic analyses of chloroplast trnK intron and nuclear ribosomal ITS DNA sequences
yield significant improvements in our understanding of relationships, character evolution …

DNA sequencing studies of the granule-bound starch synthase gene (GBSSI) indicate the
presence of two loci in Viburnum. Gene trees from separate and combined phylogenetic …

Plant traits that mediate mutualistic interactions are widespread, yet few studies have linked
their macroevolutionary patterns with the ecological interactions they mediate. Here we …

Premise A key question in plant dispersal via animal vectors is where and why fruit colors
vary between species and how color relates to other fruit traits. To better understand the …

The potential biological activities of Viburnum stellato-tomentosum (VS), a plant mainly
found in Costa Rica, have yet to be reported. Supplementation of VS extract for 17 weeks …
