Phylogeography and post-glacial dynamics in the clonal-sexual orchid Cypripedium calceolus L
Aim We investigated the phylogeographical history of a clonal-sexual orchid, to test the hypothesis that current patterns of genetic diversity and differentiation retain the traces of climatic fluctuations and of the species reproductive system. Location Europe, Siberia and Russian Far East. Taxon Cypripedium calceolus L. (Orchidaceae). Methods Samples (>900, from...Gargiulo, Roberta ; Pironon, Samuel ; Zheleznaya, Ekaterina ; Sanchez, Michele ; Balázs, Zoltan …

Genetic diversity in British populations of Taxus baccata L.: Is the seedbank collection representative of the genetic variation in the wild?
Seed banking is an invaluable tool in plant conservation, both as an archive and a source of genetic variation. Despite the increasing focus on the validation of sampling strategies, few studies have empirically related diversity in seed bank collections with variation in wild-provenance populations. By using a set of nuclear...Gargiulo, Roberta ; Saubin, Méline ; Rizzuto, Gabriele ; West, Bede ; Fay, Michael …

Conservation of the threatened species Pulsatilla vulgaris Mill. (pasqueflower) is aided by reproductive system and polyploidy
Population loss due to habitat disturbance is a major concern in biodiversity conservation. Here we investigate the genetic causes of the demographic decline observed in English populations of P ulsatilla vulgaris and the consequences for conservation. Using ten nuclear microsatellite markers, we compare genetic variation in wild populations with restored...
