Genetic diversity is essential to the survival and resilience of all species, yet very few studies characterizing the intraspecific genetic diversity of rare species have been carried out. In this study, we assessed and described the genetic diversity and structure of two rare and endemic Myrceugenia species (Myrtaceae) from the Brazilian Atlantic Forest using microsatellite markers developed specifically for each species. We...

Characterizing genetic diversity and structure of populations is essential for the effective conservation of threatened species. Orchis patens sensu lato is a narrowly distributed tetraploid species with a disjunct distribution (i.e., Northern Italy, North Africa and the Canary Islands), which is facing a severe decline. In this study, we evaluated levels of genetic diversity and population structuring using 12 new nuclear mic...

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 56 locations) were genotyped at 11 nuclear microsatellite loci...
