背景情况:
- 昆虫是重要的生态系统组成部分,由于气候变化而面临越来越多的极端温度.
- 了解昆虫生命史对温度的反应对于预测种群动态和生态系统服务,如害虫监管至关重要.
- 缺乏对昆虫生命史权衡的比较研究,这阻碍了对气候变化影响的概括.
研究的目的:
- 系统地审查和对温度对跨物种蕾丝鸟 (神经) 生命史动态的影响进行元分析.
- 为了研究生存,发育和繁殖中特定阶段的温度敏感性.
- 为了识别潜在的生命历史的权衡,以应对温度变化.
主要方法:
- 对生态学研究的系统文献综述 蕾丝翅.
- 对将生命史特征 (生存,发育,繁殖) 与温度联系起来的定量数据的元分析.
- 对62种物种的生命历史过程中温度敏感度的计算.
主要成果:
- 在所有研究的蕾丝鸟物种中,随着温度的增加,发育时间持续下降.

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.

Requirements for Human Life
8.1K
The Earth and its atmosphere have provided humans with air, water, and food, but these are not the only requirements for survival. Humans also require a specific range of temperature and pressure that the Earth and its atmosphere provides.
Oxygen
Atmospheric air is only about 20 percent oxygen, but that oxygen is a key component of the chemical reactions that keep the body alive, including the reactions that produce ATP. Brain cells are susceptible to a lack of oxygen because they require a...
