概括
气候变化变暖事件对杉芽虫的生存和发展的影响最小. 然而,气候变暖改变了昆虫的能量储备,这对未来的森林害虫爆发有影响.
科学领域:
- 环境科学 环境科学
- 昆虫生态学 昆虫生态学
- 气候变化生物学 气候变化生物学
背景情况:
- 气候变化不成比例地影响冬季条件,变暖事件影响昆虫生理.
- 杉芽虫 (Choristoneura fumiferana) 是一个重要的森林害虫,对温度波动敏感.
- 了解昆虫对冬季变暖的反应对于预测生态和经济影响至关重要.
研究的目的:
- 为了研究模拟冬季早期变暖事件对杉芽虫生存,发育,身体状况和生物化学的影响.
- 评估不同强度和持续时间的变暖如何影响这一森林害虫的关键绩效指标.
主要方法:
- 在冬季休眠期间,杉芽虫幼虫被暴露在4个变暖强度和4个持续时间的因数设计中.
- 测量包括生存率,发育时间,身体状况 (例如脂质和糖原度) 和生化标志物.
主要成果:
- 芽虫的生存和发育时间基本上不受模拟的变暖事件的影响.
- 身体状况表现出性别特异的变化,但没有受到温暖治疗的显著影响.
- 加热处理改变了能量储备:增加强度降低了脂质度,而中间加热最大化了糖原度.
结论:
- 冬季早期的变暖事件似乎对芽虫在休眠期间的表现产生了最小的直接影响.
- 脂质和糖原度的变化表明可能对休眠后的能量和昆虫表现产生间接影响.
- 需要进一步的研究,以了解改变代谢物度对森林害虫动态的长期影响.

There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...

Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

Organisms must balance energy intake with the energy required for growth, maintenance and reproduction. These trade-offs result in a variety of survivorship and reproductive strategies, including semelparity and iteroparity. Semelparous species, like annual plants, have only one reproductive episode in their lifetimes and consequently have short lifespans. Iteroparous species, by contrast, have many reproductive events during their lifetimes but have relatively few offspring. These two...
