Light PollutionClimate change, pesticides and land use changes alone cannot fully explain the decline in insect populations. Scientists from the Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB) have now discovered that regions of Germany that have experienced a sharp decline in flying insects also have high levels of light pollution. Many studies already suggest that artificial light at night has negative impacts on insects, and scientists should pay greater attention to this factor when exploring the causes of insect population declines in the future.
The biomass of flying insects has decreased by more than 75%. This alarming figure made front page news in autumn 2017. The study, published in 2017, analyzed trends in biomass of flying insects in selected protected areas within agricultural landscapes over the last 27 years, and concluded that changes of climate and habitat are to blame for the decline in insect populations. At the same time, they pointed out that these impacts alone are unable to explain this drastic decline.

Light at the wrong time disturbs the balance of ecosystems

Clearly an assignment for scientists from the Light Pollution and Ecophysiology research group at IGB. After all, they know from previous studies that artificial lighting at night strongly affects the number of insects and insect communities. Therefore, the team led by IGB researcher Dr. Maja Grubisic looked at the locations of the areas involved in the 2017 study: areas in conurbations that have a higher than average level of light pollution.

“Half of all insect species are nocturnal,” explains Maja Grubisic. “As such, they depend on darkness and natural light from the moon and stars for orientation and movement or to escape from predators, and to go about their nightly tasks of seeking food and reproducing. An artificially lit night disturbs this natural behaviour and has a negative impact on their chances of survival.” This was the starting point of their investigation.

The scientists analyzed all recent studies on the effects of artificial light at night on insects, and found that there is strong evidence to suggest a credible link between light pollution and declines in insect populations. For example, flying insects are attracted by artificial lights — and, at the same time, are removed from other ecosystems — and die from exhaustion or as easy prey. Additionally, rows of lights prevent flying insects from spreading, causing a lack of genetic exchange within fragmented insect populations that could reduce their resistance to other negative environmental influences, which are especially pronounced in agrarian areas.

A decline in insect populations in agricultural areas, which make up no less than eleven per cent of land use worldwide, does not only mean a decline in species diversity, but also jeopardizes important ecosystem services; for example, there are then fewer moths, beetles and flies to pollinate plants. Also, changes in the occurrence and behaviour of pests such as aphids or their enemies such as beetles and spiders can disturb the balance of this well-tuned system. Furthermore, artificial light at night may also have a direct impact on the growth and flowering time of plants, and therefore on yield.

All influencing factors have to be understood and considered — including light pollution

“Our overview study shows that artificial light at night is widely present and can have complex impacts in agricultural areas, with unknown consequences for biodiversity and crop production. Thus, light pollution should be generally considered as a potential ecosystem disturbance in future studies to identify ways in which practical steps can be taken to reduce environmental concerns“, summarizes Dr. Franz Hölker, Head of the Light Pollution and Ecophysiology research group at IGB.

Today we are all concerned with the energy we consume within our homes. But how many truly understand the ins and outs of home energy use, and where exactly does the electrician and the development of energy management systems come into play. There is much to consider when discussing home energy use. The consumer first off needs to be informed about energy use, how it is calculated and ultimately billed if they are to make changes to their energy consumption rates. But in terms of educating consumers does the residential electrician have a role? And beyond that are manufacturers developing products designed to help electricians and consumers better understand residential energy use? Throughout this article we will deal with each of these important questions.

Jeremy Herrington

Total Electrical Solutions was founded in 2013 by Jeremy Herrington in Quispamsis, on the outskirts of Saint John, New Brunswick. Since 2013 Jeremy has steadily grown Total Electrical Solutions in the residential, commercial and construction sectors. The growth is primarily the result of Jeremy’s customer first philosophy, plus his over 20 years of industry experience.

Jeremy grew up learning about the industry from his father who was an electrical contractor. Jeremy spent his early years helping and watching his father as a contractor and business owner. After high school Jeremy was, like many, not wholly aware of the course he wished to take and so he began an electrical apprenticeship at his father’s company.
