Teaching Ecology of water vertebrates/ Ecology of fish
University of South Bohemia

V návaznosti na ostatní limnologické a hydrobiologické přednášky se tento předmět bude zabývat rolí vodních obratlovců ve vodním systému. Z tohoto hlediska budou probírány všechny tradiční discipliny ekologie ryb, jakožto nejdůležitější skupiny vodních obratlovců v našich podmínkách: adaptace na vodní prostředí, reprodukce, potrava, chování, populační dynamika atd. Ostatním vodním obratlovcům bude věnováno místo podle jejich významu pro naše posluchače.


In connection with other limnological and hydrobiological lectures this course is dealing with the role of aquatic vertebrates, particularly fish, in the water system. It contains especially traditional fish ekology and ichthyology disciplines,: adaptation to the aquatic environment, reproduction, food, behavior, population dynamics, etc. Other aquatic vertebrates will be given space according to their importance in aquatic ecosystems.
