“…They demonstrated that white LEDs do not attract more insects than the others, highlighting the necessity to use these lights to reduce disturbances across multiple insect taxa. Recently, Larsson et al (2020) demonstrated similar behaviour as the above-mentioned for birds, but for Trichoptera , whose attraction to light varied among species, females are more influenced than males. These authors registered an atypical flight activity when the lamps were turned on at night.…”

Light pollution is the consequence of elevated lighting emitted by human-made artefacts to the lower atmosphere. Recently, there have been major advances in the assessment and mitigation of light pollution impacts on humans and the natural ecosystems. Severe negative impacts of light pollution have been highlighted while very few mitigation measures have been implemented. People (scientists, policymakers or stakeholders) interested in light pollution may not have a holistic perspective of the problem, and also there is a need for incorporating social and natural dimensions. Therefore, the main goal of this paper is to review the literature on light pollution using ISI Web of Science by paying attention to the (i) type of publication, year and journal; (ii) impacts on specific elements; (iii) location and (iv) methods used. Our results indicated that the elevated number of papers come from a diverse range of disciplines, methods, places and scales. It is clear that light pollution is getting enough attention from the scientific community but decisions on the implementation of mitigation measures are left with the stakeholders, ordinary inhabitants, policymakers and politicians. Nevertheless, light pollution is having impacts on the health of humans and the natural ecosystem as perceived by experts and inhabitants having divergent perspectives. Thus, light pollution is multifaceted but difficult to be faced, mitigated and not holistically understood. This review paper groups the total impacts of light pollution on the Earth presents some contradictory results, summarises mitigation measures, and provides specific future research directions.

“…Without additional research, however, the results from this study cannot be extrapolated to infer population-level impacts. In addition to the limited temporal duration of this study, the effects of ALAN vary with habitat and species and with the intensity and spectra of nocturnal lighting [31,60]. Nonetheless, reduced abundance of certain caterpillar species near light sources [23] and the implication of ALAN as a driver of moth population declines [61] stresses the need for further research to scale individual to population-level effects.…”

Artificial light at night increases top-down pressure on caterpillars: experimental evidence from a light-naive forest

Artificial light at night (ALAN) is a globally widespread and expanding form of anthropogenic change that impacts arthropod biodiversity. ALAN alters interspecific interactions between arthropods, including predation and parasitism. Despite their ecological importance as prey and hosts, the impact of ALAN on larval arthropod stages, such as caterpillars, is poorly understood. We examined the hypothesis that ALAN increases top-down pressure on caterpillars from arthropod predators and parasitoids. We experimentally illuminated study plots with moderate levels (10–15 lux) of LED lighting at light-naive Hubbard Brook Experimental Forest, New Hampshire. We measured and compared between experimental and control plots: (i) predation on clay caterpillars, and (ii) abundance of arthropod predators and parasitoids. We found that predation rates on clay caterpillars and abundance of arthropod predators and parasitoids were significantly higher on ALAN treatment plots relative to control plots. These results suggest that moderate levels of ALAN increase top-down pressure on caterpillars. We did not test mechanisms, but sampling data indicates that increased abundance of predators near lights may play a role. This study highlights the importance of examining the effects of ALAN on both adult and larval life stages and suggests potential consequences of ALAN on arthropod populations and communities.

“…Moreover, the data sets are dominated by studies on Lepidoptera, although there are few studies investigating the effects of ALAN on other insect groups or species (e.g. see Larsson et al ., 2020 for a study on Trichoptera). In terms of lighting, the majority of these studies investigated effects of one type of light source (e.g.…”

1. Widespread and significant declines of insect population abundances and biomass are currently one of the most pressing issues in entomology, ecology and conservation biology. It has been suggested that artificial light at night is one major driver behind this trend.2. Recent advances in the gathering and analysis of long-term data sets of insect population and biomass trends, however, have mostly focused on the effects of climate change and agricultural intensification.3. We posit here that adequate assessment of artificial night at light that would be required to evaluate its role as a driver of insect declines is far from trivial. Currently its implementation into entomological monitoring programmes and long-running ecological experiments is hampered by several challenges that arise due to (i) its relatively late appearance as a biodiversity threat on the research agenda and (ii) the interdisciplinary nature of the research field where biologists, physicists and engineers still need to develop a set of standardised assessment methods that are both biologically meaningful and easy to implement.4. As more studies that address these challenges are urgently needed, this article aims to provide a short overview of the few existing studies that have attempted to investigate longer-term effects of artificial light at night on insect populations. 5. To improve the quality and relevance of studies addressing artificial light at night and its effect on insects, we present a set of best practise recommendations where this field needs to be heading in the coming years and how to achieve it.
