"Feeding with speed: prey capture evolution in cichlids" . "4"^^ . "Diverzita pohybov\u00FDch a potravn\u00EDch syst\u00E9m\u016F ryb je velmi vysok\u00E1 a p\u0159esto existuje jen velmi m\u00E1lo informac\u00ED o integrovan\u00E9 evoluci t\u011Bchto dvou syst\u00E9m\u016F. V nas\u00ED studii jsme pouzili fylogeneticky nez\u00E1visl\u00E9 kontrasty ke studiu vztahu rychlosti p\u0159ibl\u00EDzen\u00ED pred\u00E1tora ke ko\u0159isti (RS) a velikosti \u00FAstn\u00EDho otvoru (MG). Jako modelovou skupinu jsme vybrali 18 druh\u016F z diverzifikovan\u00E9 skupiny st\u0159edoamerick\u00FDch cihlid. K zachycen\u00ED potravn\u00EDho chov\u00E1n\u00ED byla pouzita vysokorychlostn\u00ED kamera. Sekvence dvou gen\u016F cytb a S7 byly pouzity k vytvo\u0159en\u00ED fylogenetick\u00E9 hypot\u00E9zy o p\u0159\u00EDbuznosti studovan\u00FDch druh\u016F. Nase v\u00FDsledky ukazuj\u00ED pozitivn\u00ED korelaci mezi velikost\u00ED \u00FAstn\u00ED dutiny a rychlost\u00ED \u00FAtoku na ko\u0159ist. Nase v\u00FDsledky tak nazna\u010Duj\u00ED, ze druhy s v\u011Bts\u00ED velikost\u00ED \u00FAstn\u00ED dutiny si mohou dovolit vyss\u00ED rychlost \u00FAtoku na ko\u0159ist."@cs . "Hulsey, C. D." .

"The diversity of both the locomotor and feeding systems in fish is extensive,although little is known about the integrated evolution of the two systems. We have used phylogenetic-independent contrasts to study the relationship between the predator closing speed(RS) and mouth size (MG) during prey capture in 18 species of neotropical cichlids. High-speed digital video camera was used to study the prey capture sequences. To provide a robust comparative framework, we augmented existing phylogenetic information available from the mitochondrial cytochrome b gene with sequences from the S7 nuclear ribosomal intron for these species. Our finding is that RS is positively correlated with mouth size. We predict that species that are more flexible with regard to the accuracy required during a feeding strike, because of their ability to exhibit a larger gape, will generally exhibit greater attack speeds."@en .
