subspecies is used to describe variable taxa that persisted over significant geological periods and their evolutionary relationship. In addition, numerous other taxa from various genera were observed and described as new species, including Stephanodiscus Ehrenberg (5); Cyclotella (Kützing) Brébisson (1); Pantocsekiella K.T.Kiss & Ács (1); Navicula Bory (3); Placoneis Mereschkowsky (2); Eolimna Lange-Bertalot & W.Schiller (1); Fallacia Stickle & D.G.Mann (1); Aneumastus D.G. Mann & Stickle (1); Encyonema Kützing (1); Cymbella C.Agardh (1) and Cymbopleura (Krammer) Krammer (1). Most of them appear in the lake’s earliest phases and are likely endemic to the lake. Moreover, many of the endemic or relict taxa living in the lake today were also found in larger populations in the fossil sediments. These include relict species such as Amphora transylvanica Pantocsek; Diploneis mauleri (Brun) Cleve; Navicula hastata Jurilj; Cymbopleura budayana (Pantocsek) Krammer, and endemic species like Aneumastus macedonicus Levkov; Diploneis neglecta Jovanovska & Levkov; Gomphonema mihoi Levkov; Placoneis significans Lange-Bertalot; Campylodiscus marginatus Jurilj, among others. These results provide a comprehensive overview of the diatom community in Lake Ohrid over time and provide a basis for understanding the evolutionary and environmental forces that have shaped the current diversity in this ancient freshwater ecosystem.
