Diversity of Algae and Cyanobacteria and Bioindication Characteristics of the Alpine Lake Nesamovyte (Eastern Carpathians, Ukraine) from 100 Years Ago to the Present

The species diversity and changes in the structural dynamics of algal flora from alpine lake Nesamovyte has been studied for 100 years. During period investigations, 234 (245 infraspecific taxa) were revealed to cover more than 70% modern composition lake. biodiversity algae is characterized by an increase number widespread forms, a change baseline “montane” complex comparison beginning 20th century. Nevertheless, Lake still unique that typical high-mountainous European lakes. presence different conventionally arctic algae, particular, diatoms discussed. Structural taxonomic as well leading genera, their are revealed. An ecological analysis showed vulnerability degradation ecosystem On this basis, issue regarding question protection preservation significance uniqueness
