KHAPUGIN, Anatoliy A  e  KUNAEVA, Elena N. Abundance dynamics of endangered plant species Galatella rossica (Asteraceae) in the Republic of Mordovia (Central Russia): short report. Arnaldoa [online]. 2017, vol.24, n.1, pp.239-246. ISSN 1815-8242.

The population-based studies of vulnerable plant species provide important data on both their own ecological preferences and environmental conditions of habitats. Galatella rossica is endangered plant species included in the Red Data Book of the Republic of Mordovia (Central Russia). In the region, it is known from six micropopulations. None of them is located within the regional protected areas network. We have carried out the study of abundance dynamics for two of the known populations: for location 1 -between 2009-2013-, for location 2 -between 2004-2013-. We established that the number of individuals in both studied populations has decreased. It was caused by processes of afforestation and overgrowing in habitats by tall vegetation and shrubs (e.g., Salix spp., Spiraea crenata). We suggest the resumption of more detail population-based studies in the region.
