On spatial patterns of freshwater turbellaria on an example of lake Bol’schoe Miassovo (Southern Urals)

We investigate spatial patterns of turbellaria in a temperate freshwater reservoir on an example of mesotrophic lake (Southern Urals). Lake has a complex morphometry and high diversity of substrates. It is shown that the most important factors of turbellarian dispersal are swash, oxygen regime, moderate water heating and, to a lesser extent, depth of light penetration (for species with symbiotic algae).
