Comparative Population Biology of Critically Endangered Dracocephalum austriacum (Lamiaceae) in Two Distant Regions

Abstract

Our study aims to compare the population dynamics of critically endangered species, Dracocephalum austriacum, in two distant regions (Czech and Slovak Karst) with similar habitat conditions, and to evaluate if conclusions concerning factors affecting population performance in one region could help in understanding species dynamics in the other region. Results show that populations in the Slovak Karst are performing better than populations in the Czech Karst.

The transitions contributing most to the population growth rates are very similar between the regions except for contributions of seedling growth and stasis of large adults. These differences need to be considered before using information about the most important life cycle transitions in other regions.

We suggest that similar results would be found for other species with narrow habitat requirements occupying very similar habitats, even in very distant regions.
