Effects of artifical light at night (ALAN) on three benthic grazer species (Arbacia lixula, Paracentrotus lividus, Cerithium spp.) from the Adriatic Sea (June - August 2021)@en

In laboratory experiments on field-collected animals (June-August 2021), we investigated the influence of three realistic artificial light at night (ALAN) regimes on food consumption rates and feeding rhythmicity in the sea urchins Arbacia lixula and Paracentrotus lividus and the snail Cerithium spp. from the Adriatic Sea (Pula, Croatia). Food consumption was assessed in assays with algal pellets, while feeding rhythms were documented with 24 h time-lapse photography. Both was done in animals that had been acclimated to ALAN for two weeks and in non-acclimated animals. We observed short-term and potential long-term alterations in the feeding rhythms of Cerithium spp. and Paracentrotus lividus, respectively, but found no lasting effects on consumption rates. Effects were less pronounced when ALAN was applied only part-night. Data contains (1) information about place and time of the animal collection, (2) details about the laboratory experiments, (3) measured food consumption rates under ALAN, (4) day-/night feeding behaviour under ALAN derived from time-lapse photography, and (5) consumption rates under red light. Data for all three species is provided.2021年6月至8月，我们针对野外采集的实验动物开展室内实验，探究了三种符合自然场景的夜间人工光照（artificial light at night, ALAN）方案，对亚得里亚海（克罗地亚普拉海域）采集的海胆Arbacia lixula、Paracentrotus lividus以及Cerithium属螺类的摄食速率与摄食节律的影响。摄食速率通过藻类颗粒投喂实验进行评估，摄食节律则通过24小时延时摄影记录。上述实验均在经夜间人工光照驯化两周的动物与未驯化的动物中开展。研究结果显示，Cerithium属螺类与Paracentrotus lividus的摄食节律分别出现短期与潜在长期改变，但未观测到摄食速率受到持续影响。仅在夜间部分时段施加夜间人工光照时，上述效应会显著减弱。本数据集包含五类核心信息：(1) 实验动物的采集地点与时间详情；(2) 室内实验的详细参数；(3) 夜间人工光照条件下测得的摄食速率数据；(4) 由延时摄影衍生得到的夜间人工光照下的昼夜摄食行为数据；(5) 红光照射条件下的摄食速率数据。所有受试的三个物种种群的相关数据均已完整提供。
