Polyploidy, ecological niche and demographic development of the wetland annual plant species Cyperus fuscus
Abstract
Genome duplications are known to play an important role in the evolution of plant genomes and eventually in speciation, but the ecological consequences of polyploidization are still poorly understood. The project is concerned with the geographic distribution, ecological niche and historical demographic development of diploid and tetraploid populations of the ecologically extremely specialized ephemeral plant species Cyperus fuscus, a character species of endangered Isoëto-Nanojuncetea habitats and a target species for traditionally used ponds in Central Europe. The study area spans Austria, the Czech Republic and Slovakia and encloses a putative borderline between diploids (Czech Republic) and tetraploids (Slovakia). We will combine genome size measurements, chromosome counts, field ecological investigations and herbarium investigations. The results will also be of relevance for formulating conservation guidelines for the vulnerable Cyperus fuscus.
