Plasticity of storage allocation in Daphnia magna
Date de publication
Energy storage is crucial for those organisms, like Daphnia, that live in environments with fluctuating food supply. Here we investigate the patterns of storage allocation in Daphnia magna Straus, and we test energy allocation model proposed by McCauley et al. We show that when refed after a period of starvation, the animals first restore storage at a supranormal level, mainly at the expense of reproduction. We also show that this higher storage level improves the response of animals to further bout of starvation, and we propose both functional and structural explanations for this pattern.
