AB [EN] The extraordinary diversity in long-livedlakes is largely driven by distinct eco-evolutionaryprocesses. With their unique biota and numerousendemic taxa, these lakes are key settings for fundamentalstudies related to ecology, diversity, andevolution. Here, we test how the environment shapesdiatom diversity and community patterns over space inancient Lake Ohrid. By applying Bray–Curtis similarityanalyses of diatom community data, includingwidespread and endemic taxa, we identified two majorzones: littoral and sublittoral. The latter one is beingcharacterized with higher endemic diversity. The aand b diatom diversity and community distribution inthe northern and eastern part of the lake are influencedby the presence of vertical (bathymetrical) andhorizontal barriers. The zonation of the diatomcommunities appears driven by two large-scale factors:(i) water depth, and (ii) water chemistry, primarily,the concentration of total phosphorus, nitrogenammonia, and conductivity. Both drivers appear toequally influence diatom diversity and communitypatterns. We present initial data on diatom–environmentrelations, where the results support earlierecological studies emphasizing the relevance ofongoing human-induced eutrophication in the northernlake area. This study provides background informationon the role of the environment in structuringcontemporary diatom diversity. However, futureresearch needs to focus on the biotic componentincluding species competition in order to reveal themechanisms driving spatial community dynamics inLake Ohrid
