“…Contrary to our predictions, as well as the findings from a laboratory study on coral reef fish larvae, A. triostegus [ 57 ], we observed a negative, rather than a positive, impact of ALAN on growth which was 15%, 21%, and 51% lower in terms of height, length, and weight, respectively. Growth is a complex process influenced by many interacting physiological and ecological factors and their trade-offs [ 55 , 59 ] and the observed lower growth may be due to negative effects on growth-related physiology.…”

“…If feeding was decreased under continuous light exposure, then anemonefish growth may have traded-off against survival and may explain the observed decrease in growth under ALAN. Lower survival may also be due to physiological stress as laboratory studies showed that ALAN decreased the survival of A. triostegus larvae in the absence of predators [ 57 ], caused a 12% reduction in the lifespan of the fruit fly Drosophila melanogaster [ 13 , 28 ], and ALAN decreased the condition of wild bird nestlings [ 58 ]. However, our results do not allow us to differentiate between physiological stress and predation to determine the cause of higher mortality in the wild under ALAN.…”

Long-term exposure to artificial light at night in the wild decreases survival and growth of a coral reef fish

Artificial light at night (ALAN) is an increasing anthropogenic pollutant, closely associated with human population density, and now well recognized in both terrestrial and aquatic environments. However, we have a relatively poor understanding of the effects of ALAN in the marine realm. Here, we carried out a field experiment in the coral reef lagoon of Moorea, French Polynesia, to investigate the effects of long-term exposure (18–23 months) to chronic light pollution at night on the survival and growth of wild juvenile orange-fin anemonefish, Amphiprion chrysopterus . Long-term exposure to environmentally relevant underwater illuminance (mean: 4.3 lux), reduced survival (mean: 36%) and growth (mean: 44%) of juvenile anemonefish compared to that of juveniles exposed to natural moonlight underwater (mean: 0.03 lux). Our study carried out in an ecologically realistic situation in which the direct effects of artificial lighting on juvenile anemonefish are combined with the indirect consequences of artificial lighting on other species, such as their competitors, predators, and prey, revealed the negative impacts of ALAN on life-history traits. Not only are there immediate impacts of ALAN on mortality, but the decreased growth of surviving individuals may also have considerable fitness consequences later in life. Future studies examining the mechanisms behind these findings are vital to understand how organisms can cope and survive in nature under this globally increasing pollutant.

“…The early-life period of an animal might be particularly sensitive to adverse environmental influences, which could change developmental trajectories and have implications for adult physiology and behaviour ( Gluckman et al, 2005 ). Early-life lighting conditions have been found to affect the development of the circadian system ( Brooks and Canal, 2013 ; Fonken and Nelson, 2016 ), with effects on, for example, food intake ( Cissé et al, 2017 ), fear response ( Borniger et al, 2014 ), body mass ( Raap et al, 2016b ), growth rate and survival ( O'Connor et al, 2019 ).…”

The large-scale impact of urbanization on wildlife is rather well documented, however the mechanisms underlying the effects of urban environments on animal physiology and behaviour are still poorly understood. Here, we focused on one major urban pollutant - artificial light at night (ALAN) - and its effects on the capacity to mount an innate immune response in wild great tit Parus major nestlings. Exposure to ALAN alters circadian rhythms of physiological processes, by disrupting the nocturnal production of the hormone melatonin. Nestlings were exposed to a light source emitting 3 lux for seven consecutive nights. Subsequently, nestlings were immune-challenged with a lipopolysaccharide injection, and we measured haptoglobin and nitric oxide levels pre- and post-injection. Both haptoglobin and nitric oxide are important markers for innate immune function. We found that ALAN exposure altered the innate immune response, with ALAN nestlings having lower haptoglobin and higher nitric oxide levels after the immune-challenge compared to dark-night nestlings. Unexpectedly, nitric oxide levels were overall, lower after the immune-challenge than before. These effects were likely mediated by melatonin, since ALAN-treated birds had on average 49% lower melatonin levels than the dark-night birds. ALAN exposure did not have any clear effects on nestling growth. This study provides a potential physiological mechanism underlying the documented differences in immune function between urban and rural birds observed in other studies. Moreover, it gives evidence that ALAN exposure affects nestling physiology, potentially causing long-term effects on physiology and behaviour, which ultimately can affect their fitness.

“…Manriquez et al (2019) reported that juvenile Chilean abalone (Concholepas concholepas) exposed to ALAN in the laboratory experienced longer self-righting times, higher metabolic rates, and were less frequently found near food sources. Convict surgeonfish (Acanthurus triostegus) larvae exposed to ALAN in the laboratory experienced changes in swimming behavior and significantly higher mortality rates compared to control fish, but they also grew faster and heavier than control fish (O'Connor, Fobert, Besson, Jacob, & Lecchini, 2019). Juvenile ALAN-exposed intertidal rockfish, Girella laevifrons, had increased oxygen consumption and activity and no longer ANNUAL LITERATURE REVIEW displayed the natural activity cycles compared to control fish (Pulgar et al, 2019).…”

This review covers selected 2019 articles on the biological effects of pollutants, including human physical disturbances, on marine and estuarine plants, animals, ecosystems, and habitats. The review, based largely on journal articles, covers field, and laboratory measurement activities (bioaccumulation of contaminants, field assessment surveys, toxicity testing, and biomarkers) as well as pollution issues of current interest including endocrine disrupters, emerging contaminants, wastewater discharges, marine debris, dredging, and disposal. Special emphasis is placed on effects of oil spills and marine debris due largely to the 2010 Deepwater Horizon oil blowout in the Gulf of Mexico and proliferation of data on the assimilation and effects of marine debris microparticulates. Several topical areas reviewed in the past (e.g., mass mortalities ocean acidification) were dropped this year. The focus of this review is on effects, not on pollutant sources, chemistry, fate, or transport. There is considerable overlap across subject areas (e.g., some bioaccumulation data may be appeared in other topical categories such as effects of wastewater discharges, or biomarker studies appearing in oil toxicity literature). Therefore, we strongly urge readers to use keyword searching of the text and references to locate related but distributed information. Although nearly 400 papers are cited, these now represent a fraction of the literature on these subjects. Use this review mainly as a starting point. And please consult the original papers before citing them.
