摘要：

1. Newly synthesized proteins and total protein synthesis were examined in eight different age-groups in the cladoceran Daphnia magna, under normal and heat-stressed conditions. 2. Protein expression varied with the age of the animal as well as in response to heat-shock. 3. Heat-shock does not induce the same heat-shock proteins (HSP) in all age groups. 4. Some of the HSP are present constitutively and are upregulated in heat stress. 5. If HSP confer protection to the organism, there may be unwanted variation in tolerance to environmental stressors in organisms used in bioassays.
