Global patterns of moss diversity: taxonomic and molecular inferences
Shaw, A. J.; Cox, C. J.; Goffinet, B.Taxonomic and molecular data were utilized to test the hypothesis that moss diversity is greatest near the equator. Species richness estimates from 86 taxonomic checklists representing global moss diversity do not support the hypothesis that, in general, mosses are more species-rich in the tropics than at higher latitudes.
Phylogenetic significance of the rpoA loss in the chloroplast genome of mosses
Goffinet, B.; Wickett, N. J.; Shaw, A. J.; Cox, C. J.A recent survey of arthrodontous mosses revealed that their chloroplast genome lacks the gene encoding the alpha subunit of the RNA polymerase (i.e., rpoA), and that at least in Physcomitrella patens the gene has been transferred to the nuclear genome. Subsequently the gene was recorded from the cytoplasmic genome in Takakia and Sphagnum. Here we extend the survey to representatives of all major lineages of mos...
Circumscription, classification, and taxonomy of Amblystegiaceae (Bryopsida) in...
Vanderpoorten, A.; Hedenäs, L.; Cox, C. J.; Shaw, A. J.Results from a previous broad-scale analysis employing trnL-trnF sequence data for 168 Hypnalean and 11 Hookerialean taxa, and an analysis employing two chloroplast regions, trnL-trnF and atpB-rbcL, one nuclear region, the internal transcribed spacers of 18S-26S rDNA, plus 68 morphological characters for a reduced data set of 54 Hypnalean taxa, were used to circumscribe Amblystegiaceae. The analyses provided tw...
