Light pollution in complex ecological systems

Light pollution has emerged as a burgeoning area of scientific interest, receiving increasing attention in recent years. The resulting body literature revealed diverse array species-specific and context-dependent responses to artificial light at night (ALAN). Because predicting generalizing community-level effects is difficult, our current comprehension the ecological impacts on complex systems remains notably limited. It critical better understand ALAN's higher levels organization order comprehend mitigate repercussions ALAN ecosystem functioning stability amidst ongoing global change. This theme issue seeks explore systems, by bridging various realms scaling up from individual processes functions communities networks. Through this integrated approach, collection aims shed intricate interplay between pollution, dynamics humans world increasingly impacted anthropogenic lighting. article part 'Light systems'.

The effects of artificial light at night (ALAN) on the circadian biology of marine animals

Frontiers in Marine Science, Год журнала: 2024, Номер 11

Опубликована: Фев. 7, 2024

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

Artificial light at night alters the locomotor behavior of the Mediterranean sea urchin Paracentrotus lividus

Marine Pollution Bulletin, Год журнала: 2024, Номер 206, С. 116782 - 116782

Опубликована: Авг. 2, 2024

Artificial light at night (ALAN) is a recognized source of anthropogenic disturbance, although its effects on biological systems have not been fully explored. Within marine ecosystems, coastal areas are the most impacted by ALAN. Here, we focused Mediterranean sea urchin Paracentrotus lividus, which has crucial role in shaping benthic ecosystems. Our objective was to investigate if ALAN affects nocturnal locomotor behavior P. lividus. A semi-controlled field study conducted along rocky shore near promenade lit night. Results suggested potential impact urchins. Individuals lividus tended move away from sources while directions dark conditions were uniform. Their performance, presence ALAN, characterized shorter latency time, lower sinuosity and higher mean speed increasing intensity, with cascading effect ecosystem level.

Abstract Light pollution is a pervasive global stressor to natural systems. However, due the proximity of human activities along coasts and open ocean, light yet commonly overlooked pollutant in many marine habitats.

Antagonistic Effects of Light Pollution and Warming on Habitat‐Forming Seaweeds

Ecology and Evolution, Год журнала: 2024, Номер 14(10)

Опубликована: Окт. 1, 2024

Artificial Light at Night (ALAN) is an emerging global stressor that likely to interact with other stressors such as warming, affecting habitat-forming species and ecological functions. Seaweeds are dominant in temperate marine ecosystems, where they support primary productivity diverse communities. Warming a major seaweed forests, but effects of ALAN on seaweeds largely unknown. We manipulated (0 lx vs. 25 night) temperature (ambient +1.54°C warming) test their independent interactive the survival, growth (biomass, total-, blade- stipe-length) function (photosynthesis, respiration) juveniles two seaweeds, kelp

Assessment of Artificial Light at Night Across Geographical Features in the Sicilian Coastal Zone

Land, Год журнала: 2024, Номер 13(12), С. 2219 - 2219

Опубликована: Дек. 18, 2024

This study investigates the impact of artificial light at night (ALAN) along Sicilian coasts, using satellite data from 2016 to 2023, focusing on three distinct spatial domains: terrestrial areas within 1 km coastline, marine extending up offshore, and nautical mile coast. In coastal zones, ALAN is a significant anthropogenic pressure with potentially detrimental effects ecosystems. By integrating geographic datasets such as Corine Land Cover (CLC), Natura 2000 protected areas, Posidonia oceanica meadows, this aims characterize analyse temporal variations in across these domains. The findings reveal substantial differences pollution between domains over time, exhibiting highest levels ALAN. contrast, further offshore experience reduced pollution, particularly 1-nautical-mile domain. also indicates that especially those network, show significantly lower than non-protected highlighting effectiveness conservation efforts. Statistical analyses, including ANOVAs, demonstrate factors domain, year, province, CLC classes influence distribution. advocates for considering critical factor environmental assessments, under Maritime Spatial Planning Directive (MSP) Marine Strategy Framework (MSFD), providing valuable insights support policies aimed mitigating

Artificial Light Increases Nighttime Prevalence of Predatory Fishes, Altering Community Composition on Coral Reefs

Global Change Biology, Год журнала: 2024, Номер 30(12)

Опубликована: Дек. 1, 2024

ABSTRACT Artificial light at night (ALAN) is an anthropogenic pollutant that intensifying and expanding in marine environments, but experimental studies of community‐level effects are generally lacking. The inshore, shallow, clear‐water locations coral reefs their diverse photosensitive inhabitants make these ecosystems highly susceptible to biological disturbances; the same time, biodiversity accessibility them model systems for wider insight. Here, we experimentally manipulated ALAN using underwater LED lights on a Polynesian reef system investigate influence localised nighttime fish communities compared control sites without ALAN. We collected infrared video censuses baseline prior manipulation, which repeated following short‐term (mean three nights) prolonged 25 exposures Short‐term exposure did not induce any significant alterations community, increased species richness. Species compositions exposed were more dissimilar from sites. difference between community was apparent family level; instead, it observed composition trait guilds. Following exposure, diurnal nocturnal predatory (piscivores, invertivores, planktivores)—particularly those site‐attached or mobile within reefs—were present assemblages. Our findings show coastal could cause trophic imbalances circadian disturbances communities. Given community‐wide consequences only after suggests management duration artificial lighting potentially be used reduce impacts ecosystems.
