Abstract: PREMISE Whole genome duplication is considered a major mechanism of sympatric speciation due to the creation of strong and instantaneous reproductive barriers. Although post-zygotic reproductive isolation between diploids and polyploids is often expected, the extent… read more here.

DOI: 10.1007/s00606-019-01581-7
Abstract: Prospero autumnale (Hyacinthaceae) is taxonomically intricate geophyte species complex with a circum-Mediterranean distribution. In contrast to the extraordinary karyological diversity within P. autumnale complex, morphological variation is limited, and thus, reliable taxonomically diagnostic traits are… read more here.

DOI: 10.1007/s00606-021-01770-3
Abstract: The morphological variation and cytotype diversity were investigated among Central European populations traditionally recognized as Dactylorhiza fuchsii, recently incorporated in D. maculata s.l. Flow cytometry was employed to assess the ploidy levels of 738 individuals… read more here.

DOI: 10.3732/ajb.1700153
Abstract: PREMISE OF THE STUDY Detailed knowledge about the karyological diversity of organisms undoubtedly represents one of the crucial steps toward a better understanding of their evolutionary trends and history. We investigated the cytotype and absolute… read more here.
