Nannochloropsis limnetica decreases eicosapentaenoic acid in D. magna.
“D. magna fed heat-stressed algae contained significantly lower levels of the essential polyunsaturated fatty acid (PUFA) eicosapentaenoic acid (EPA)”

Nannochloropsis limnetica has no effect on lipid peroxidation in D. magna.
“This was accompanied by higher antioxidant capacity in D. magna fed heat-stressed algae, but no differences in lipid peroxidation were observed.”

Nannochloropsis limnetica extends lifespan in D. magna.
“D. magna kept at either 12°C or 28°C (but not at 20°C) achieved a significantly higher lifespan when feeding on heat-stressed algae”
Model organismsMaintained at 12°C or 28°C; compared with non-stressed or cold-stressed algae; no benefit at 20°Cheat-stressed algae grown at 25°C

Nannochloropsis limnetica improves short-term heat tolerance in D. magna.
“Daphnia magna maintained at either 20°C or 28°C and consuming heat-stressed algae had a significantly higher short-term heat tolerance.”

Gradual warming is associated with fecundity in D. magna.
“initially reproduced more than controls, but suffered shorter lifespans and lost their reproductive advantage near 30 °C”
Model organismsInitial reproductive advantage over controls disappeared near 30 °C+1 °C every 4–6 generations, up to 32 °C30 generations

Caloric restriction has no effect on lifespan in D. magna.
“Specifically, short-lived genotypes show no caloric restriction (CR) effect, while long-lived ones expand their lifespan even further under CR.”
