概括

夜间的人工光 (ALAN) 扰乱了蝶的发育. 色LED光线似乎比蓝色或白色光线对彩绘蝶的变形不那么破坏性.

科学领域:

昆虫学昆虫学是一门学科.
时间生物学时间生物学
环境科学环境科学

背景情况:

夜间人工照明 (ALAN) 是一个日益严重的环境问题.
光周期是昆虫生命周期的关键提示,影响昼夜节律和现象学.
类,包括蝶,对光线线很敏感,因此容易受到ALAN的干扰.

研究的目的:

研究ALAN对绘画蝶 (Vanessa cardui) 的发育时间的影响.
确定ALAN的不同持续时间和波长如何影响毛虫变形.
评估人工照明对蝶生命周期的潜在破坏.

主要方法:

商业来源的Vanessa cardui毛虫是在23°C的控制条件下养的.
毛虫被暴露在白色LED光线 (300 lux) 的不同持续时间 (0.9.5,17.5,24小时) 中.
随后的实验将毛虫暴露在24小时的白色,蓝色或色LED光线和12小时的ALAN条件下,测量和成年人出现的天数. 还分析了血淋巴中的黑激素水平.

主要成果:

长时间暴露于白色LED光 (17.5和24小时) 与较短时间暴露 (9.5小时) 相比,加速蝶的出现时间为1-3天.
被色LED照射的蝶比被蓝色或白色LED照射的蝶出现的速度稍慢 (1-2天).
蓝色LED曝光显著降低了Vanessa cardui的血淋巴黑色素水平.

结论:

艾伦显著影响了Vanessa cardui的转型时间.
与蓝色或白色光相比,色LED光似乎对蝶发育和昼夜节律的影响较小.
这些发现强调了需要考虑光污染对昆虫表观和保护工作的影响.

关键词:

晚上的人工灯在夜间.类类动物 (Lepidoptera) 是一种类动物.黑激素是什么意思黑激素是什么意思变形转化是一种转化.可见的波长是可见的波长.

Frequency-dependent Selection

Frequency-dependent Selection

When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.

Migration

Migration

Migration is long-range, seasonal movement from one region or habitat to another. This common strategy, carried out by many different organisms around the world, is an adaptive response that typically corresponds to changes in an organism’s environment, like resource availability or climate. Migrations can involve huge groups of thousands of animals as well as single individuals traveling alone and can range from thousands of kilometers to just a few hundred meters.
