Abstract The globally widespread adoption of Artificial Light at Night (ALAN) began in the mid‐20th century. Yet, it is only last decade that a renewed research focus has emerged into its impacts on ecological and biological processes marine environment are guided by natural intensities, moon phase, light dark cycles daily spectra alterations. field diversified rapidly from one restricted to handful vertebrates, which have been quantified across broad array coastal habitats species. Here, we review current understanding ALAN diverse ecosystems. presents state knowledge key ecosystems (sandy rocky shores, coral reefs pelagic) taxa (birds sea turtles), introducing how can mask seabird turtle navigation, cause changes animals predation patterns failure spawning synchronization, as well inhibition zooplankton Diel Vertical Migration. Mitigation measures recommended, however, while strategies for mitigation were easily identified, barriers implementation poorly understood.

Coastal greening of grey infrastructure: an update on the state-of-the-art

Proceedings of the Institution of Civil Engineers - Maritime Engineering, Journal Year: 2024, Volume and Issue: unknown, P. 1 - 69

In the marine environment, greening of grey infrastructure (GGI) is a rapidly growing field that attempts to encourage native life colonize artificial structures enhance biodiversity, thereby promoting ecosystem functioning and hence service provision. By designing multifunctional sea defences, breakwaters, port complexes off-shore renewable energy installations, these can yield myriad environmental benefits, in particular, addressing UN SDG 14: Life below water. Whilst GGI has shown great promise there evidence base, remain many criticisms knowledge gaps, some feel scope for be abused by developers facilitate harmful development.

The fundamental change in nocturnal landscapes due to the increasing use of artificial light at night (ALAN) is recognized as being detrimental environment and raises important regulatory questions whether how it should be regulated based on manifold risks environment. Here, we present results an analysis current legal obligations ALAN context with a systematic review adverse effects. includes relevant aspects European German environmental law, specifically nature conservation immission control. represents 303 studies indicating significant disturbances organisms landscapes. We discuss conditions for prohibitions by laws protection gaps persist and, hence, specific legislation pollution necessary. While predominantly provided species special status that reveal avoidance behavior artificially lit associated habitat loss, effects without are often unaddressed existing regulations. Legislative shortcomings caused difficulties proving effect population level, detecting lighting malpractice, applying law ALAN-related situations.

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

Proceedings of the Royal Society B Biological Sciences, Journal Year: 2021, Volume and Issue: 288(1952), P. 20210454 - 20210454

Artificial light at night (ALAN) is an increasing anthropogenic pollutant, closely associated with human population density, and now well recognized in both terrestrial aquatic environments. However, we have a relatively poor understanding of the effects ALAN marine realm. Here, carried out field experiment coral reef lagoon Moorea, French Polynesia, to investigate long-term exposure (18–23 months) chronic pollution on survival growth wild juvenile orange-fin anemonefish, Amphiprion chrysopterus .

The application of lighting technologies developed in the 20th century has increased brightness and changed spectral composition nocturnal night-time habitats night skies across urban, peri-urban, rural, pristine landscapes, subsequently, researchers have observed disturbance biological rhythms flora fauna. To reduce these impacts, it is essential to translate relevant knowledge about potential adverse effects artificial light at (ALAN) from research into applicable urban practice. Therefore, aim this paper identify report, via a systematic review, exposure different physical properties sources on various organism groups, including plants, arthropods, insects, spiders, fish, amphibians, reptiles, birds, non-human mammals (including bats, rodents, primates).

How the relative impacts of anthropogenic pressures on natural environment vary between different taxonomic groups, habitats, and geographic regions is increasingly well established. By contrast, times day at which those are most forcefully exerted or have greatest influence not understood. The impact nighttime bears particular scrutiny, given that for practical reasons (e.g., researchers themselves belong to a diurnal species), studies conducted during daytime organisms predominantly active in ways do differentiate nighttime. In present article, we synthesize current state knowledge environment, highlighting key findings examples. evidence available suggests under intense stress across increasing areas world, especially from pollution, climate change, overexploitation resources.
