| Description
| - V řece Ohři (Česká republika) byli radiotelemetricky sledováni jedinci mníka jednovousého s cílem zjistit, zda obsazuje speciálně vymezený domovský okrsek. Rovněž byla testována hypotéza, že velikost domovského okrsku koreluje s množstvím ryb. Další hypotézou bylo, že chování během dne je určeno dostupností úkrytů v říčním prostředí. Hypotézy byly testovány pomocí analýzy údajů o pohybech ryb ve vztahu k hloubce, rychlosti průtoku, velikosti substrátu a spádu toku. V noci mníci preferovali větší hloubky s nižším spádem a jemnější substrát než během denního světla. Domovský okrsek byl menší v oblastech s nízkým nebo žádným spádem a signifikantně se zvětšoval při stoupajícím spádu řeky. Nebyl zjištěn vztah mezi velikostí domovského okrsku a množstvím ryb. Velikost domovského okrsku je zřejmě určena hlavně spádem řeky. (cs)
- To determine whether burbot occupy defined home range in rivers, we radio-tracked individuals in the Ohře River in the Czech Republic. We also tested the hypothesis that the size of burbot home range would correlate with the fish mass. Burbots strong attraction to suitable refuges was the basis for our second hypotheses, that its diurnal behavior would reflect refuge availability in the riverine environment. To test these hypotheses, we analyzed data on fish movements in relation to depth, velocity, substratum size and river slope. During the night, burbot preferred deeper areas with lower slope and finer substrates than during daylight hours. The home range was smaller in areas with low or zero slopes, and significantly increased with increasing river slope. There was no relationship between home range size and fish mass. River slope appeared to be the main predictor of the burbots home range size.
