ABSTRACT Ecological light pollution (ELP) is quickly becoming a worldwide concern and can negatively affect aquatic ecosystems. The given intensity and spectrum of a light source can influence how organisms function within their environment. These properties of artificial lighting at night (ALAN) and their impacts on the physiology and behaviour of crayfish were examined in this work. Hemolymph was obtained from crayfish to quantify a physiological response. Behavioural data were measured as the number, duration, and maximum intensity of agonistic fights. Exposure to higher intensities of light and the presence of ultraviolet light induced a behavioural trend, resulting in significantly altered social interactions within both species of crayfish. The number and maximum intensity of lights significantly decreased, whereas the duration of time spent fighting significantly increased. Due to the importance of freshwater environments and the role crayfish play as a keystone species, examining how crayfish are impacted from ALAN is imperative to maintaining the health of aquatic ecosystems.

夜间人造光的强度和光谱改变了小龙虾的相互作用

摘要 生态光污染 (ELP) 正迅速成为全球关注的问题，并对水生生态系统产生负面影响。给定的光源强度和光谱会影响生物体在其环境中的功能。这项工作研究了夜间人工照明 (ALAN) 的这些特性及其对小龙虾生理和行为的影响。从小龙虾中获得血淋巴以量化生理反应。行为数据被测量为激烈战斗的数量、持续时间和最大强度。暴露于更高强度的光和紫外线的存在会引起行为趋势，导致两种小龙虾的社会互动发生显着改变。灯的数量和最大强度显着下降，而战斗时间显着增加。由于淡水环境的重要性以及小龙虾作为关键物种的作用，研究小龙虾如何受到 ALAN 的影响对于维持水生生态系统的健康至关重要。
