Abstract Background Migration of a population from its founder is expected to cause reduction genetic diversity and facilitates differentiation between the population, as predicted by theory isolation distance. Consistent with that theory, model expansion single predicts patterns in populations can be explained well their geographic founders, which correlated differentiation. Methods To investi...

The salamander killing fungus Batrachochytrium salamandrivorans (Bsal), recently introduced from Asia, is threatening populations in different parts of Europe. In fact, this pathogen rapidly spreading Central Europe and has been also into NE Spain. Of special concern are those regions with an exceptionally high diversity such as Italy, where 19 species present most which strictly endemic. study...

To examine if the cultivation process has reduced the genetic variation of modern cultivars of the traditional Chinese medicinal plant, Coptis chinensis, the levels and distribution of genetic variation was investigated using ISSR markers. A total of 214 C. chinensis individuals from seven wild and three cultivated populations were included in the study. Seven ISSR primers were used and a total...
