Food competition between waterbirds and fish
 Bečvář, Viktor ; Hořák, David (advisor) ; Musil, Petr (referee)
Food competition between waterbirds and fish can be a crucial factor in todays wetland ecosystems. In certain situations it can be decisive if a specific site is still suitable for waterbirds or not. Large aquatic invertebrats are often shared food resource. Situations where specific waterbirds and fish compete for this resource were described in many wetland habitats. Fish are often much more effective in acquiring food to the point when this relationship can be described as asymetrical competition. The level of competition can be also influenced by various envirometal factors or different attributes of waterbird and fish populations. The knowledge obtained by studing this relationship can be then used in management of protected areas and comercially used waterbodies.
