Diatoms of Lakes Prespa and Ohrid - Chapter headings: Abstract/ Quickfinder for the plates/ Introduction/ Meterial, methods and investigated area/ Observations/ New Combinations/ Characteristics of diatoms from Lake Prespa and Ohrid/ Acknowledgements/ References / Index of Taxa. Lakes Preska and Ohrid belong to the old tectonic oligomictic deep isolated lakes, which have a high percentage of endemic biota and which are also considered as centers of speciation. This volume offers the results of a three year basic taxonomical research in the area. A total of 450 taxa is presented, 78 (17.3%) being described as new taxa ( 1 new genus, 73 species and 4 varieties) and 9 taxa gained new combinations or status. Presence of relict species has been confirmed. Navicula turris HUSTEDT is reported for the first time outside the Kopecz Tertiary deposits in a recent lake.
