Patterns and drivers of phylogenetic structure of pteridophytes in China
Global Ecology and Biogeography, 2021Aim: Previous studies have found strikingly different geographical patterns of phylogenetic diversity of gymnosperms and angiosperms, which have been suggested to result, in part, from the greater age of the former.

Bhutanese pteridophytes have been compiled into a check-list of 568 taxa (543 species and 25 additional subspecies), based on reidentification of nearly all the world’s herbarium holdings from the Country, studied by the first author. We have also carried out many field-excursions, particularly in west and east Bhutan, collecting and identifying ...

Chromosome studies of pteridophytes had their major impetus in the work of Irene Manton (1) who was the first to show the far-reaching significance of Polyploidy in these plants. Her work was followed not only by numerous investigations by her own students at the University of Leeds but by researchers in many parts of the world, including especially ...

Spore viability is defined as the time that spores retain their capacity to germinate. It is a factor of primary importance in the establishment of fern species and populations in a new habitat after spore dispersal. Viability is typically maintained for a long period in pteridophytes, but there are great variations in both interspecific and ...
