Artificial lighting at night (ALAN) produced by urban, industrial, and roadway lighting, as well other sources, has dramatically increased in recent decades, especially coastal environments that support dense human populations.

At the individual level, ALAN elicit a suite physiological behavioral responses associated light-mediated processes such diel activity predator-prey interactions. also been shown to modify community composition trophic structure, implications for ecosystem-level including primary productivity, nutrient cycling, energetic linkages between aquatic terrestrial systems. Here, we review state science relative impacts on estuaries, which is an important step assessing long-term sustainability regions. We first consider how multiple properties (e.g., intensity content) influence interaction physiology behavior estuarine biota (drawing from studies invertebrates, fishes, birds). Second, link individual- community- responses, focus food webs ecosystem functions. Coastal communities ecosystems have identified key priority research, cohesive research framework will be critical understanding mitigating ecological consequences.

Artificial light during the polar night disrupts Arctic fish and zooplankton behaviour down to 200 m depth

Communications Biology, Journal Year: 2020, Volume and Issue: 3(1)

Published: March 5, 2020

Abstract For organisms that remain active in one of the last undisturbed and pristine dark environments on planet—the Arctic Polar Night—the moon, stars aurora borealis may provide important cues to guide distribution behaviours, including predator-prey interactions. With a changing climate increased human activities Arctic, such natural light sources will many places be masked by much stronger illumination from artificial light. Here we show normal working-light ship disrupt fish zooplankton behaviour down at least 200 m depth across an area >0.125 km 2 around ship. Both quantitative qualitative nature disturbance differed between examined regions. We conclude biological surveys illuminated ships introduce biases sampling, bioacoustic surveys, possibly stock assessments commercial non-commercial species.

Effects of artificial light on bird movement and distribution: a systematic map

Environmental Evidence, Journal Year: 2021, Volume and Issue: 10(1)

Published: Dec. 1, 2021

Abstract Background Artificial light is ubiquitous in the built environment with many known or suspected impacts on birds. Birds flying at night are to aggregate around artificial and collide illuminated objects, which may result from attraction and/or disorientation. In other contexts, birds repelled by light-based deterrents, including lasers spotlights. can also change birds’ perceptions of habitat quality, resulting selection avoidance areas. Studies documenting aggregation, deterrence, typically considered separate literature bodies, but they actually study a common set populations, interventions/exposures, responses. Our systematic map provides comprehensive, searchable database evidence effects bird movement distribution, increasing both quantity diversity studies that accessible for further comparison synthesis. We identify describe available four secondary questions relevant conservation management: aggregation/mortality structures lights, attracts disorients birds, deterrent efficacy, influence continuous illumination selection. Methods Using principles reviews methods published an earlier protocol, we conducted extensive interdisciplinary search. searched multidisciplinary citation indices as well databases websites specific conservation, pest management, transportation, energy. our map, included all reporting eligible populations (birds), interventions/exposures (artificial light), outcomes (movement through space, behaviour preceding movement, distribution). evaluated based meta-data fields related context, population traits, source characteristics, outcome variables. used these each question aspects support (evidence clusters) others require more research (knowledge gaps).

Artificial light at night (ALAN) is a disruptive form of pollution, impacting physiological and behavioural processes that may scale up to population community levels. Evidence from terrestrial habitats show the severity type impact depend on wavelength intensity ALAN; however, research marine organisms still limited. Here, we experimentally investigated effect different ALAN colours primary producers. We tested green (525 nm), red (624 nm) broad-spectrum white LED ALAN, compared dark control, microalgae Tetraselmis suecica diatom assemblage. boosted chlorophyll production abundance in T. .

Synopsis Artificial light at night (ALAN) is a pervasive anthropogenic pollutant, emanating from urban and suburban developments reaching nearly all ecosystems dense forests to coastlines. One proposed strategy for attenuating the consequences of ALAN modify its spectral composition forms that are less disruptive photosensory systems. However, complicated pollutant manage due extensive variation in mechanisms diverse ways these manifest biological ecological contexts.
