概括
运动控制,半夜LED照明可以减轻人工光对蝙蝠的负面影响. 虽然一般有效,但即使是暖色的灯光也会影响敏感物种,特别是随着路径使用的增加.
科学领域:
- 生态生态学 生态生态学
- 环境科学 环境科学
- 野生动物保护 野生动物保护
背景情况:
- 光污染是影响野生动物,特别是夜生活物种的日益严重的问题.
- 道路和自行车道上的运动控制照明对蝙蝠等夜行动物构成风险.
- 以前的研究表明,人工光对蝙蝠活动有不良影响.
研究的目的:
- 调查人工光对蝙蝠的负面影响的缓解策略.
- 为了评估将半夜照明与运动控制的暖色LED相结合的有效性.
- 评估照明时间和颜色对不同环境中的蝙蝠活动的影响.
主要方法:
- 在四个月的时间里,在郊区和农村环境的自行车道上,对蝙蝠活动的声学监测.
- 实施半夜照明 (从23:00到05:00关闭) 结合运动控制的暖色LED.
- 在郊区测试不同的光间持续时间 (20s vs 40s) 和在农村地区测试珀色光对森林专家蝙蝠的影响.
主要成果:
- 照明方案不会对城市周边地区的蝙蝠活动产生负面影响,无论间隔的持续时间如何.
- 在农村地区,森林专家蝙蝠活动在黄昏时减少,但在黎明时没有珀色的光.
- 大多数其他蝙蝠物种在响应测试的照明条件时表现出不受影响的活动水平.
结论:

02:16Light Acquisition
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.
02:00Photoreceptors and Plant Responses to Light
Light plays a significant role in regulating the growth and development of plants. In addition to providing energy for photosynthesis, light provides other important cues to regulate a range of developmental and physiological responses in plants.
01:10Electrical Energy
Using electric appliances for a longer period of time consumes more electrical energy and results in a higher electric bill. The energy produced by the transfer of electrons from one point to another is known as electrical energy. If power is delivered at a constant rate, the electrical energy can be defined as the product of power used by the device for a period of time. The energy unit on electric bills is the kilowatt-hour, where one kilowatt-hour is equivalent to 3.6 × 106 joules. The...
