Red List of Bulgarian algae. II. Microalgae

Абстракт

The Red List presented in this paper is focused on Bulgarian non-marine microalgae which face a risk of extinction. The assignment to each IUCN Red List category is  according to the seven specific criteria and their relative values in the new method for evaluation of the threatened status of microalgae (Stoyneva-Gärtner et. al., this volume). The list contains 756 taxa (613 species, 82 varieties and 61 forms) from 7 divisions, classified in six IUCN categories and shows that threatened microalgae represent 14% the total algal biodiversity of Bulgaria.
