Abstract:ABSTRACT. An experiment was conducted to evaluate the effect of temperature on the intensity of predation upon snails. The experiment was run for 60 days using 15 cement tanks with water temperatures of 18, 22, 26, 30 and 34°C in a completely randomized design with three replications. The pearl cichlids (n = 4 per tank) were distributed in tanks with heaters, which increased the water temperature by 1°C h -1 , in a room held at 17°C. The snails were selected (up to 3 mm) and distributed among the tanks (n = 32… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
