Artifcial light at night does not alter heart rate orCaribbean spiny lobsterlocomotor behaviour in(Panulirus argus):insights into light pollution andphysiological disturbance using biologgers
Light pollution is a rapidly growing threat to biodiversity, with many unknown or poorly understood effects on species andecosystems spanning terrestrial and aquatic environments, Relative to other taxa, the effects of artifcial light at night onaquatic invertebrates are poorly understood, despite the abundance and integral signifcance of invertebrates to marine andfreshwater ecosystems. We affxed heart rate and acceleration biologgers to adult Caribbean spiny lobster (Panulirus argus), anecologically, culturally and economically signifcant species in the western Atlantic ocean,to test the effect of artifciallight atnight on this species' physiology and behaviour relative to appropriate controls. The experiment was conducted in a simulatedreef mesocosm in The Bahamas with incandescent lighting used to iluminate it at 1 lux, approximating ight levels ofshoreof urban areas. In the conditions tested here, artifcial light at night was found to have no effect on heart rate or locomotoractivity in p argus. We observed a dissociation between activity and heart rate at both short-term and long-term temporalsca es, Lobsters were more active at niaht and nocturna activity was higher in trials coser to new moon: however, heart ratedid not vary with diel or lunar cycle, There was less than 8% diference between daytime and night time average heart ratedespite the average percentage of time spent active almost tripling in nights versus days, to 19.5% from 7.2%, respectivelyOur fndings suggest P, argus may have some resilience to low levels of light pollution, which warrants further research onaspects of this species' life history, performance and ftness in the,face ofthis potential anthropogenic disturbance.

光污染对生物多样性构成了迅速增长的威胁，对陆地和水生环境中的物种和生态系统产生了许多未知或知之甚少的影响。与其他类群相比，夜间人工光对水生无脊椎动物的影响知之甚少，尽管无脊椎生物对海洋和淡水生态系统具有丰富和整体意义。我们将心率和加速度生物记录仪安装到成年加勒比刺龙虾(Panulirus argus)上，这是一种在西大西洋具有生态、文化和经济意义的物种，以测试夜间人工光照对该物种生理和行为的影响。这项实验是在巴哈马的一个模拟珊瑚礁中透镜中进行的，使用白炽灯照明，照明亮度为1勒克斯，接近城市地区近海的光线水平。在这里测试的条件下，在夜间人工照明被发现有没有影响的心率或自发活动的P.argus。我们观察到活动和心率在短期和长期的时间尺度之间的解离。龙虾在夜间更活跃，在接近新月的试验中夜间活动更高;然而，心率不会随 DIEL 或月球周期而变化。 白天和夜间的平均心率相差不到8%，尽管夜间活动时间的平均百分比几乎是白天的三倍，分别从7.2%增至19.5%。我们的研究结果表明P.可能对低水平的光污染有一定的适应性，这需要进一步研究该物种的生活史、表现和适应性，以应对这种潜在的人为干扰。
