Lifelong exposure to artificial light at night impacts stridulation and locomotion activity patterns in the cricket Gryllus bimaculatus
<p>This dataset contains data from a laboratory experiments described in the paper: "<span>Levy, K., Wegrzyn, Y., Efronny, R., Barnea, A., & Ayali, A. 2021 Lifelong exposure to artificial light at night impacts stridulation and locomotion activity patterns in the cricket <i>Gryllus bimaculatus.</i> Proc. R. Soc. B 20211626. <a href="https://doi.org/10.1098/rspb.2021.1626">https://doi.org/10.1098/rspb.2021.162</a></span>". </p> <p>Artificial light at night (ALAN) is increasing worldwide,with most of the world population living under light-polluted skies. Growing awareness of the harmful effects of ALAN calls for more comprehensive understanding of these effects. <span>The stridulation and locomotion patterns of adult male crickets reared under different lifelong ALAN intensities were monitored simultaneously for five consecutive days in custom-made anechoic chambers. Activity periods and acrophases were compared between the experimental groups. </span></p> <p><span>Control crickets exhibited a robust rhythm, stridulating at night and demonstrating locomotor activity during the day. In contrast, ALAN affected both the relative level and timing of the crickets' nocturnal and diurnal activity. ALAN induced free-running patterns, manifested in significant changes in the median and variance of the activity periods, and even arrhythmic behavior. The magnitude of disruption was light intensity dependent, revealing an increase in the difference between the activity periods calculated for stridulation and locomotion in the same individual. </span></p> <p><span>Our results demonstrate that ecologically-relevant ALAN intensities affect crickets' behavioral patterns, and may lead to decoupling of locomotion and stridulation behaviors at the individual level, and to loss of synchronization at the population level. </span></p>

Video track of stridulating Stauroderus scalaris (Fischer von Waldheim, 1846) (Orthoptera: Acrididae)
<p>This video accompanies the occurrence record of <em>Stauroderus scalaris </em>(Fischer von Waldheim, 1846) at <a href="https://www.inaturalist.org/observations/53932082">https://www.inaturalist.org/observations/53932082</a> (as well as <a href="https://www.gbif.org/occurrence/2823184397">https://www.gbif.org/occurrence/2823184397</a>).</p> <p>While another male is singing loud in the background, the filmed male is first producing only soft chirps, and adds loud chirps at 0:00:16. At 0:00:22 a rivalling male flies in (not filmed) while producing its typical rasping flight chirp. From then on, both males sing concurrently.</p> <p>The clear sounding "frrree" in the background is from the bird <em>Fringilla coelebs</em> (Chaffinch).</p>
