将人造光引入野生动物栖息地代表了人类入侵的一种迅速扩大的形式，特别是在沿海系统中。光污染会改变海龟筑巢时的行为;因此，在佛罗里达（美国）的海滩照明中，需要使用长波长的光-低压钠蒸气和虫灯-以最大限度地减少对海龟的影响。我们研究了这两种光对圣罗莎海滩鼠（Peromyscuspoliontusleucocephalus）觅食行为的影响。我们比较了补丁使用和放弃密度的小鼠实验食物补丁建立沿着梯度的人工光在外地。小鼠在这两种类型的人造光附近利用的食物斑块比在光线不足的地区少，在虫灯附近的斑块内收获的种子也少。我们的研究结果表明，人造光影响沿海地区的陆地物种的行为，光污染值得更多的考虑在保护规划。
Introduction of artificial light into wildlife habitat represents a rapidly expanding form of human encroachment, particularly in coastal systems. Light pollution alters the behavior of sea turtles during nesting; therefore, long-wavelength lights-low-pressure sodium vapor and bug lights-that minimize impacts on turtles are required for beach lighting in Florida (U.S.A.). We investigated the effects of these two kinds of lights on the foraging behavior of Santa Rosa beach mice ( Peromyscus polionotus leucocephalus). We compared patch use and giving-up densities of mice for experimental food patches established along a gradient of artificial light in the field. Mice exploited fewer food patches near both types of artificial light than in areas with little light and harvested fewer seeds within patches near bug lights. Our results show that artificial light affects the behavior of terrestrial species in coastal areas and that light pollution deserves greater consideration in conservation planning.
