Life history responses of Daphnia pulicaria to diets containing freshwater diatoms: Effects of nutritional quality versus polyunsaturated aldehydes
Daphnia pulicaria diets containing freshwater diatoms nutritional quality polyunsaturated aldehydes
2014/5/9
Like marine diatoms, some freshwater diatoms produce α, β, γ, δ-polyunsaturated aldehydes (PUA) when damaged. Some of these oxylipins are suspected of impairing egg viability in marine copepods. To de...
