自然黑暗的夜间环境由于夜间人工照明的引入而被广泛侵蚀(艾伦)艾伦的生物影响随强度和光谱的不同而不同，但已从分子到生态系统进行了记录。这些影响的全球严重程度在很大程度上取决于艾伦的时空分布与物种地理范围之间的关系。在这里，我们确定了仙人掌家族的这种关系。利用1992年至2012年期间仙人掌地理范围和夜间稳定光合成图像的地图，我们发现1992年有很高比例的仙人掌物种在其范围内经历了艾伦现象，到2012年这一比例有所增加。从1992-1996年到2008-2012年，几乎所有仙人掌物种(89.7%)的地理范围被照亮的百分比都有显著增加。一个地区的物种丰富度与濒危物种的物种丰富度呈显著负相关，与艾伦水平呈显著负相关。仙人掌可能对艾伦这种广泛和持续的入侵它们的地理范围特别敏感，特别是在考虑到与其他人为压力的影响存在相加和协同作用的可能性时。
Naturally dark nighttime environments are being widely eroded by the introduction of artificial light at night (ALAN). The biological impacts vary with the intensity and spectrum of ALAN, but have been documented from molecules to ecosystems. How globally severe these impacts are likely to be depends in large part on the relationship between the spatio-temporal distribution of ALAN and that of the geographic ranges of species. Here, we determine this relationship for the Cactaceae family. Using maps of the geographic ranges of cacti and nighttime stable light composite images for the period 1992 to 2012, we found that a high percentage of cactus species were experiencing ALAN within their ranges in 1992, and that this percentage had increased by 2012. For almost all cactus species (89.7%) the percentage of their geographic range that was lit increased from 1992–1996 to 2008–2012, often markedly. There was a significant negative relationship between the species richness of an area, and that of threatened species, and the level of ALAN. Cacti could be particularly sensitive to this widespread and ongoing intrusion of ALAN into their geographic ranges, especially when considering the potential for additive and synergistic interactions with the impacts of other anthropogenic pressures.
