Microbial diversity and community respiration in freshwater sediments influenced by artificial light at night

Abstract: An increasing proportion of the Earth's surface is illuminated at night. In aquatic ecosystems, artificial light at night (ALAN) may influence microbial communities living in the sediments. These communities are highly diverse and play an important role in the global carbon cycle. We combined field and laboratory experiments using sediments from an agricultural drainage system to examine how ALAN affects communities and alters carbon mineralization. Two identical light infrastructures were installed parallel t… Show more

“…To maximally utilize the setup and to gain as much information as possible on ecological changes in response to illumination, it should also serve as a nucleus for future experiments that may help to understand how ALAN affects natural ecosystems. Initial results from this experimental site about the skyglow level [44] and the impact of ALAN on microbial diversity and community respiration in freshwater sediments [12] have been recently published. Other researchers are explicitly invited to contact the corresponding authors if they would like to perform a study at the facility.…”

“…Assigning one site as the treatment and the other as the control is adequate for a deductive experiment, provided the a priori probability of corroboration is known [33]. When this is not feasible, experiments can be complemented by replicated laboratory studies as was done in a related study of microbial communities [12]. In the future, control (dark) and experimental (lit) sites can be alternated in order to corroborate any findings.…”

“…Artificial light can most certainly be used for photosythesis, as a photon from the sun may be no different from one emitted by a light bulb, they may only be different in intensity or colour. However, the rate at which photosythesis occurs is dependent on the spectral emissions of the light source [10]. Phototrophic organisms are able to carry out photosynthesis at low artificial light levels (e.g.…”
