| Description
| - 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.

- Diverzita pohybových a potravních systémů ryb je velmi vysoká a přesto existuje jen velmi málo informací o integrované evoluci těchto dvou systémů. V nasí studii jsme pouzili fylogeneticky nezávislé kontrasty ke studiu vztahu rychlosti přiblízení predátora ke kořisti (RS) a velikosti ústního otvoru (MG). Jako modelovou skupinu jsme vybrali 18 druhů z diverzifikované skupiny středoamerických cihlid. K zachycení potravního chování byla pouzita vysokorychlostní kamera. Sekvence dvou genů cytb a S7 byly pouzity k vytvoření fylogenetické hypotézy o příbuznosti studovaných druhů. Nase výsledky ukazují pozitivní korelaci mezi velikostí ústní dutiny a rychlostí útoku na kořist. Nase výsledky tak naznačují, ze druhy s větsí velikostí ústní dutiny si mohou dovolit vyssí rychlost útoku na kořist. (cs)
