The impact of habitat fragmentation and isolation on the genetic diversity of populations has attracted much attention in studies of plant conservation. The central-peripheral population hypothesis predicts that peripheral populations have reduced genetic variability, so it is often assumed that they deserve higher conservation priority over centra...

Recent phylogenetic studies have shown that Saxifraga, as currently understood, must be divided into two genera: Saxifraga L. sensu stricto and Micranthes Haw. To better understand the evolutionary history of these two genera, we performed phylogenetic analyses inferred from the nuclear ribosomal sequences from the internal transcribed spacer and t...

Centaurium scilloides is a very isolated taxon, taking into account morphological characteristics, chromosome number, and disjunct Atlantic distribution. Comparison of the Azorean plants with those living in mainland Europe reveals significant differences, which question their assimilation into a single taxon. Our molecular data inferred from seque...
