“…Such alterations can be observed in variations in activity patterns or disruptions in the expression of circadian clock genes. Examples include loss of circadian rhythm of activity in the isopod (Tylos spinulosus), arrhythmic expression of circadian clock genes in the Pacific oyster (Crassostrea gigas), higher activity levels in rockfish (Girella laevifrons) that may be attributed to a loss of internal circadian and circatidal rhythms over time, and direct effects on the rhythmic production of melatonin in European perch (Perca fluviatilis) with many fish lacking circadian melatonin rhythms as compared to control fish (Brüning et al, 2015;Duarte et al, 2019;Pulgar et al, 2019;Bottéet al, 2023).…”

“…Circadian clock genes have been identified in several marine invertebrate species including the marine annelid Platynereis dumerilii, the Pacific oyster (Crassostrea gigas), and a few Xenacoelomorphan and platyhelminth marine worms (Zantke et al, 2013;Stanton, 2015;Stanton et al, 2022;Bottéet al, 2023). Laboratory experiments have demonstrated the negative effects of ALAN exposure on these species.…”

“…For example, changes in activity patterns have been observed after switching P. dumerilii from a diurnal photoperiod to continuous light (Zantke et al, 2013). Similarly, the Pacific oyster demonstrates a comparable pattern of disruption in circadian clock gene expression and increase in valve activity when cultured under ALAN conditions (Bottéet al, 2023).…”

The effects of anthropogenic sources of light on the circadian biology of marine animals are largely unexplored at the molecular and cellular level. Given that light is a major driver of circadian rhythms at the behavioral, physiological, cellular, and even molecular levels, it is important to consider the effects that anthropogenic light, especially at night, has on aquatic species. With the expanding data generated from circadian clock research, it is surprising that these techniques have not been applied more frequently to better understand how artificial light affects animal circadian rhythms. Circadian research has been limited to behavioral and physiological observations in wild marine animals rather than a cellular and molecular understanding due to the logistical constraints. While there are some benefits to using artificial light at night (ALAN), there have also been many studies reporting physiological and behavioral consequences in response to exposure to ALAN. Here, the benefits and consequences of using ALAN in the marine environment are reviewed. Furthermore, perspectives on research limitations and future research directions are discussed. Taken together, this is an important area in which more information is required to translate our understanding of circadian biology into better practices to promote the health and welfare of marine animals.

“…The ability to perceive minute changes in dim nocturnal light suggests that these organisms are susceptible to impacts from ALAN. In fact, ALAN has been shown to disrupt the daily rhythms of the Pacific oyster, C. gigas , by increasing valve activity with ALAN intensities as low as 0.1 lux [ 66 ]. Similarly, the gaping activity (i.e.…”

Despite 22% of the world's coastal regions experiencing some degree of light pollution, and biologically important artificial light at night (ALAN) reaching large portions of the seafloor (greater than 75%) near coastal developments, the impacts of ALAN on temperate and tropical reefs are still relatively unknown. Because many reef species have evolved in response to low-light nocturnal environments, consistent daily, lunar, and seasonal light cycles, and distinct light spectra, these impacts are likely to be profound. Recent studies have found ALAN can decrease reproductive success of fishes, alter predation rates of invertebrates and fishes, and impact the physiology and biochemistry of reef-building corals. In this paper, we integrate knowledge of the role of natural light in temperate and tropical reefs with a synthesis of the current literature on the impacts of ALAN on reef organisms to explore potential changes at the system level in reef communities exposed to ALAN. Specifically, we identify the direct impacts of ALAN on individual organisms and flow on effects for reef communities, and present potential scenarios where ALAN could significantly alter system-level dynamics, possibly even creating novel ecosystems. Lastly, we highlight large knowledge gaps in our understanding of the overall impact of ALAN on reef systems. This article is part of the theme issue ‘Light pollution in complex ecological systems’.

“…ALAN has a particularly strong impact on invertebrates. The effects are variable, ranging from the disturbance of daily and seasonal rhythms [5,6], shifts in foraging behaviour [7], physiology and immune responses [8,9], and disruption to reproductive behaviours and physiology [10][11][12]. One of the most conspicuous and widely known effects is the attraction of flying insects to light at night [13,14].…”

Our planet endures a progressive increase in artificial light at night (ALAN), which affects virtually all species, and thereby biodiversity. Mitigation strategies include reducing its intensity and duration, and the adjustment of light spectrum using modern light emitting diode (LED) light sources. Here, we studied ground-dwelling invertebrate (predominantly insects, arachnids, molluscs, millipedes, woodlice and worms) diversity and community composition after 3 or 4 years of continued nightly exposure (every night from sunset to sunrise) to experimental ALAN with three different spectra (white-, and green- and red-dominated light), as well as for a dark control, in natural forest-edge habitat. Diversity of pitfall-trapped ground-dwelling invertebrates, and the local contribution to beta diversity, did not differ between the dark control and illuminated sites, or between the different spectra. The invertebrate community composition, however, was significantly affected by the presence of light. Keeping lights off during single nights did show an immediate effect on the composition of trapped invertebrates compared to illuminated nights. These effects of light on species composition may impact ecosystems by cascading effects across the food web. This article is part of the theme issue ‘Light pollution in complex ecological systems’.
