概括
夜间的人工光 (ALAN) 破坏了土的食行为,10卢克斯显著降低了表面活动. 这种改变的行为对短期碳循环过程的影响有限.
科学领域:
- 生态生态学 生态生态学
- 环境科学 环境科学
- 动物学 动物学
背景情况:
- 夜间的人工光 (ALAN) 是一个日益增长的全球污染物,影响生态系统.
- 居住在土壤中的动物,特别是夜间活跃的物种,如虫,在ALAN影响方面没有得到充分的研究.
- 地 (Lumbricus terrestris) 是重要的生态系统工程师,其表面活动对土壤过程至关重要.
研究的目的:
- 为了研究不同ALAN水平对Lumbricus terrestris夜间表面行为的影响.
- 为了确定影响土行为的ALAN强度的门.
- 评估虫行为改变对垃圾分解和土壤呼吸的影响.
主要方法:
- 控制的实验室实验测量了土在七个ALAN级别下的表面活动 (总体,风险勘探,食,表面勘探).
- 实地实验检查了ALAN对垃圾清除和土壤呼吸的影响,与观察到的行为变化相关.
- 量化了行为反应,包括10卢克斯及以上的食活动减少.
主要成果:
- 在ALAN水平为10卢克斯或更高时,地的食行为显著下降,具有强度依赖的负面影响.
- 在ALAN.下浮出水面之前,观察到风险探索增加.
- 尽管有行为变化,但在现场研究中没有发现垃圾清除或土壤呼吸的明确模式.
结论:
- 10卢克斯或更低的ALAN有效地破坏了Lumbricus terrestris的夜间表面行为.
- 观察到的行为障碍可能对碳循环过程产生最小的短期影响.
- 需要进一步的研究来了解ALAN对土壤动物和生态系统功能的长期生态影响.

Biological Clocks and Seasonal Responses
36.0K
The circadian—or biological—clock is an intrinsic, timekeeping, molecular mechanism that allows plants to coordinate physiological activities over 24-hour cycles called circadian rhythms. Photoperiodism is a collective term for the biological responses of plants to variations in the relative lengths of dark and light periods. The period of light-exposure is called the photoperiod.

Photoluminescence: Fluorescence and Phosphorescence
5.6K
Photoluminescence is a process where a molecule absorbs light energy and re-emits it in the form of light. This phenomenon occurs when a substance absorbs photons, promoting its electrons to higher energy level excited states, followed by a relaxation process in which the electrons return to their original ground state energy levels and emit light. Photoluminescence is widely observed in various materials, including semiconductors, and organic and inorganic compounds.
