In-situ and ex-situ conservation of Minuartia smejkalii
Postdoctoral project at Münzbergová group at Botany Institute at Czech Academy of Science

In this project we evaluated the consequences of ex situ hybridization between Minuartia smejkalii and a sister species Minuartia caespitosa. We found that hybrids can grow and reproduce faster than the parental species and if they are introduced by mistake in nature they could outcompete the focus endemic Minuartia smejkalii.

These two species are very similar morphologically, and we can only distinguish them observing the structures of the seeds.

Seeds of M. caespitosa (A), hybrids (B), M. smejkalii (C), and M. smejkalii from natural populations (D).

A pre-recorded talk presenting the main results about the consequences of ex-situ hybridization can be found here https://vimeo.com/493766996.

We are also investigating the effect of competition and abiotic conditions and how they change over time. Temporal data of an experiment for 4 years is being used to evaluate the interactions in the short (monthly) compared to long term (yearly 2017-2020).
