Schinkel C, Syngelaki E, Kirchheimer B, Dullinger S, Klatt S, Horandl E
Int J Mol Sci . 2020 May; 21(9). PMID: 32392879
Polyploidization and the shift to apomictic reproduction are connected to changes in DNA cytosine-methylation. Cytosine-methylation is further sensitive to environmental conditions. We, therefore, hypothesize that DNA methylation patterns would differentiate...

Klatt S, Schinkel C, Kirchheimer B, Dullinger S, Horandl E
Ann Bot . 2018 Feb; 121(7):1287-1298. PMID: 29462249
Background And Aims: Alpine plants grow in harsh environments and are thought to face occasional frost during the sensitive reproductive phase. Apomixis (asexual reproduction via seed) can be advantageous when...

Kirchheimer B, Wessely J, Gattringer A, Hulber K, Moser D, Schinkel C, et al.
Ecol Lett . 2018 Jan; 21(3):392-401. PMID: 29349850
Asexual taxa often have larger ranges than their sexual progenitors, particularly in areas affected by Pleistocene glaciations. The reasons given for this 'geographical parthenogenesis' are contentious, with expansion of the...

Schinkel C, Kirchheimer B, Dullinger S, Geelen D, De Storme N, Horandl E
Plant Syst Evol . 2017 Oct; 303(8):1093-1108. PMID: 29081576
Polyploidy is one of the most important evolutionary processes in plants. In natural populations, polyploids usually emerge from unreduced gametes which either fuse with reduced ones, resulting in triploid offspring...

Schinkel C, Kirchheimer B, Dellinger A, Klatt S, Winkler M, Dullinger S, et al.
AoB Plants . 2016 Sep; 8. PMID: 27594702
Apomictic plants expand their geographical distributions more to higher elevations compared to their sexual progenitors. It was so far unclear whether this tendency is related to mode of reproduction itself...

Kirchheimer B, Schinkel C, Dellinger A, Klatt S, Moser D, Winkler M, et al.
J Biogeogr . 2016 Aug; 43(4):716-726. PMID: 27482126
Aim: Emerging polyploids may depend on environmental niche shifts for successful establishment. Using the alpine plant as a model system, we explore the niche shift hypothesis at different spatial resolutions...

Dellinger A, Essl F, Hojsgaard D, Kirchheimer B, Klatt S, Dawson W, et al.
New Phytol . 2015 Oct; 209(3):1313-23. PMID: 26508329
Biological invasions can be associated with shifts of the species' climatic niches but the incidence of such shifts is under debate. The reproductive system might be a key factor controlling...
