摘要: Herbarium data can be useful to deduce geographical information (e.g. distribution, rarity) about plant species. The rarefaction method used compare the distribution of two or more species based on collections containing different numbers specimens. are however continually subject taxonomic revisions, which cause variation in number specimens attributed each and, as a consequence, knowledge distribution. This paper investigated effects revisions using technique. for three Asplenium ultramafic soils Tuscany before and after recent revision were analysed with use individual-based curves. Rarefaction curves set prepared appear different. starting showed great determined cuneifolium. ...
