. (2010). Differential effects of elevated nutrient and sediment inputs on survival, growth and biomass of a common larval Fsh species (Dorosoma cepedianum). ±reshwater Biology, 55, 654-669. 2. They believed that larval fish would be more successful with elevated nutrients. They tested two alternative hypotheses: "If sediment inputs negatively affect larval gizzard feeding success, then larval success would be highest when only nutrients are added and lowest when only sediments are added, and "If high turbidity enhances larval foraging activity (due to greater contrast between prey and background), we predict that larval success would be highest when both subsidy types (nutrients and sediment) are

Unformatted text preview: elevated, intermediate when either nutrients or sediments are added and the lowest when no subsidies are added." They used a 2x2 factorial design. They used four treatments of adding a mixture of sediments and/ or dissolved inorganic nutrients. The dependent variable was the larval gizzard shad (Dorosoma cepedianum). 3. They conducted a two way ANOVA test to find a significant interaction. The significant interaction showed that the effect of sediment addition on percentage survival was greater in the absence than in the presence on nutrient addition. They failed to reject the null hypothesis....
