Effect of artificial light at night on ecophysiological functions of plants
Ležal, Lukáš ; Konrádová, Hana (advisor) ; Lhotáková, Zuzana (referee)
Artificial light at night, as a significant source of anthropogenic pollution, has long been overlooked, both among the general public and in the scientific community as well as at the legislature level. Steps to reduce the negative impacts of artificial light at night have been taken late and to an insufficient extent, and it was the low general awareness that was one of the motivations for the bachelor thesis on this topic. Plants are a group of organisms that receive less attention than, for example, humans, although they far exceed them in ecological importance. Artificial light at night has the potential to alter the composition of plant communities and the food webs that are linked to them, of which humans are at the top. This is done by shifting plant phenological phases, disrupting the natural perception of day and night, modifying growth patterns and morphological characteristics, increasing irradiance stress or reducing the efficiency of photosynthesis. It is through a comprehensive knowledge of the interaction of plants with artificial light at night that society can effectively protect nature and introduce the necessary new standards and technologies to ensure sustainable development.
