缓冲环境压力对健康的不利影响的能力具有重要的生态学意义，因为在自然界中，显著的环境变化可能会定期引发压力。此外，几个应激源可能以协同的方式相互作用。本研究采用完全析因设计，在两个驯化温度(20和27 °C)和四个短期胁迫处理(对照、冷、热、饥饿)下，研究了热带蝴蝶Bcyclus anynana Butler，1879年在冷、热和饥饿条件下的塑性反应。温暖驯化的蝴蝶更耐热，但不像预期的那样耐寒。短期的寒冷和饥饿暴露降低了耐寒性和耐热性，短期的高温暴露降低了寒冷但提高了耐热性。抗饥性不受任何短期治疗的影响。因此，短期压力暴露的影响要么是中性的，要么是负面的，除了热暴露对耐热性的积极影响外，这表明了预先暴露于应激的负面影响。有趣的是，驯化温度与短期的耐热和耐寒胁迫之间存在显著的交互作用，表明较大的温差会造成更大的伤害。因此，动物通常不能从预先暴露于压力(通过“硬化”)中受益，这取决于它们以前经历的条件。强调了环境变化、胁迫和抗性之间的复杂相互作用，值得进一步研究。
The ability to buffer detrimental effects of environmental stress on fitness is of great ecological importance because, in nature, pronounced environmental variation may regularly induce stress. Furthermore, several stressors may interact in a synergistic manner. In the present study, plastic responses in cold, heat and starvation resistance are investigated in the tropical butterflyBicyclus anynanaButler, 1879, using a full factorial design with two acclimation temperatures (20 and 27 °C) and four short‐term stress treatments (control, cold, heat, starvation). Warm‐acclimated butterflies are more heat‐ but less cold‐tolerant as expected. Short‐term cold and starvation exposure reduce cold and heat resistance, and short‐term heat exposure decreases cold but increases heat resistance. Starvation resistance is not affected by any of the short‐term treatments. Thus, the effects of short‐term stress exposure are either neutral or negative, except for a positive effect of heat exposure on heat resistance, indicating the negative effects of pre‐exposure to stress. Interestingly, significant interactions between acclimation temperature and short‐term stress exposure for heat and cold resistance are found, demonstrating that larger temperature differences incur more damage. Therefore, animals may not generally be able to benefit from pre‐exposure to stress (through ‘hardening’), depending on their previously experienced conditions. The complex interactions between environmental variation, stress and resistance are highlighted, warranting further investigations.
