Artificial light at night as a new threat to pollination

  author={Eva Knop and Leana Zoller and Remo Ryser and Christopher Gerpe and Maurin H{\"o}rler and Colin Fontaine},
Pollinators are declining worldwide and this has raised concerns for a parallel decline in the essential pollination service they provide to both crops and wild plants. Anthropogenic drivers linked to this decline include habitat changes, intensive agriculture, pesticides, invasive alien species, spread of pathogens and climate change. Recently, the rapid global increase in artificial light at night has been proposed to be a new threat to terrestrial ecosystems; the consequences of this… 

Impact of artificial light at night on diurnal plant-pollinator interactions

The effect of artificial light at night on plant-pollinator interactions is not limited to the night, but can also propagate to the daytime with so far unknown consequences for the pollinator community and the diurnal pollination function and services they provide.

Nocturnal pollinators strongly contribute to pollen transport of wild flowers in an agricultural landscape

It is reported that in agricultural landscapes, macro-moths can provide unique, highly complex pollen transport links, making them vital components of overall wild plant–pollinator networks in agro-ecosystems.

Nocturnal pollination: an overlooked ecosystem service vulnerable to environmental change

There is evidence that nocturnal species are providers of pollination services (including pollination of economically valuable and culturally important crops, as well as wild plants of conservation concern), but how little is known about the scale of such services is highlighted.

An overview of anthropogenic electromagnetic radiations as risk to pollinators and pollination

Pollinators play a key functional role in most terrestrial ecosystems and provide important ecosystem service to maintain wild plant communities and agricultural productivity. The decline in

Direct and ambient light pollution alters recruitment for a diurnal plant-pollinator system.

The results suggest that ALAN can positively influence the fitness of both plants and moths in this tightly co-evolved mutualism, but the benefits to each species may depend on whether night lighting is direct or indirect.

Pollution and pollinators: A review

Biodiversity of Pollinators is declining day by day due to diverse environmental issues, posing a serious threat towards ecosystem services. This review aims to observe the pollinators’ loss due to

Negative effects of light pollution on pollinator visits are outweighed by positive effects on the reproductive success of a bat-pollinated tree

Cities are home to several species of pollinators that play an important role in the reproductive success of wild and cultivated plants that grow in these ecosystems and their surroundings. Pollution

This review focuses on mechanisms that pollinators use to find flowers at night, and the signals that nocturnally blooming flowers may employ to attract pollinators under dim light conditions, and indicates gaps in knowledge.

Pollination and fruit infestation under artificial light at night:light colour matters

It is shown that artificial light with different colours impacts plant–insect interactions differently, with direct consequences for plant fitness, and that using different light spectra than white light can reduce these effects.

‘Global Pollinator Crisis’ and Its Impact on Crop Productivity and Sustenance of Plant Diversity

Serious efforts are needed to initiate extensive studies on the pollination ecology of the authors' crops and wild species and make all possible efforts to identify and alleviate the pollinator crisis.



Ecological effects of artificial light at night on wild plants

Understanding the ecological consequences of artificial light at night is critical to determine the full impact of human activity on ecosystems and to understand fully the extent of these impacts requires conceptual models that can characterize the highly heterogeneous nature of the night-time light environment at a scale relevant to plant physiology.

Density of insect-pollinated grassland plants decreases with increasing surrounding land-use intensity.

It is shown for the first time that grassland plants dependent on insect pollination are particularly susceptible to increasing land-use intensity in the landscape.

Grazing alters insect visitation networks and plant mating systems

Habitat modification by long-term mammalian grazing fundamentally shifted visitation network structure and the state of a plant mating system, indicating how ecosystem disturbance can cascade across levels of biological organization through altered interspecific interactions.

The dark side of street lighting: impacts on moths and evidence for the disruption of nocturnal pollen transport

Findings support the disruptive impact of lights on moth activity, which is one proposed mechanism driving moth declines, and suggest that street lighting potentially impacts upon pollination by nocturnal invertebrates.

Functional Diversity of Plant–Pollinator Interaction Webs Enhances the Persistence of Plant Communities

After two years the plant communities pollinated by the most functionally diverse pollinator assemblage contained about 50% more plant species than did plant communitiespollinated by less-diverse pollination assemblages, suggesting the functional diversity of pollination networks may be critical to ecosystem sustainability.

Parallel Declines in Pollinators and Insect-Pollinated Plants in Britain and the Netherlands

Evidence of declines (pre-versus post-1980) in local bee diversity in Britain and the Netherlands is found and a causal connection between local extinctions of functionally linked plant and pollinator species is strongly suggested.

Importance of pollinators in changing landscapes for world crops

It is found that fruit, vegetable or seed production from 87 of the leading global food crops is dependent upon animal pollination, while 28 crops do not rely upon animalPollination, however, global production volumes give a contrasting perspective.

Non-bee insects are important contributors to global crop pollination

It is shown that non-bee insect pollinators play a significant role in global crop production and respond differently than bees to landscape structure, probably making their crop pollination services more robust to changes in land use.

How many flowering plants are pollinated by animals

The global number and proportion of animal pollinated angiosperms is estimated as 308 006, which is 87.5% of the estimated species-level diversity of fl owering plants.

Spatial and Temporal Trends of Global Pollination Benefit

Using detailed information on global crop yields of 60 pollination dependent or profiting crops, a map of pollination benefits on a 5′ by 5′ latitude-longitude grid is provided to guide political decisions on where to protect pollination services by investing in structural diversity of land use.
