Biodiversity of macrophytes from Lake Ohrid [The Former Yugoslav Republic of Macedonia]
2003
Talevska, M. (Hidrobioloski zavod, Ohrid (The Former Yugoslav Republic of Macedonia))
In this paper are presented the investigation of macrophytic vegetation along Macedonian shore of Lake Ohrid (Radozda-Sv.Naum). The meterial were collected from 59 localities. The results of investigations show that in investigated localities were evidenced 25 different plant species. The number of macrophytic species in different localities vary from 2 to 18 macrophytic species. The differences in the number of macrophyte species are most due to the different ecological conditions in the investigated localities: temperature, light regime, type of soil, configuration of the lake bottom, water level, nutrient amount etc.
