Hanušová, K., Čertner, M., Urfus, T., Koutecký, P., Košnar, J., Rothfels, C. J., . . . Ekrt, L. (2019). Widespread co-occurrence of multiple ploidy levels in fragile ferns (Cystopteris fragilis complex; Cystopteridaceae) probably stems from similar ecology of cytotypes, their efficient dispersal and inter-ploidy hybridization.
