Abundance of Cottus poecilopus is influenced by O2 saturation, food density and Salmo trutta in three tributaries of the Rožnovská Bečva River, Czech Republic.

abstract：:Availability of shelter is an important component of habitat selection for animals as it can influence survival (protection against harsh physical conditions and predation) and growth (energy acquisition and expenditure). Few studies address the effect of shelter on metabolic expenditures associated with non-mechanica...
