Rising temperature accelerates the responses of inducible anti-predator morphological defenses of Ceriodaphnia cornuta but decreases the responsive intensity

Cladocerans can recognize predation risk by sensing the chemical cues released by their predators, and adopt effective anti-predator defensive strategies to avoid being predated. In nature waters, temperature, as one of the key abiotic factors, fluctuates with day-night and seasons, especially under...
