Biodiversité

Anthropogenic light is ubiquitous in areas where humans are present and is showing a progressive increase worldwide. This has far-reaching consequences for most species and their ecosystems. The effects of anthropogenic light on natural ecosystems are highly variable and complex. Many species suffer from adverse effects and often respond in a highly specific manner. Ostensibly surveyable effects such as attraction and deterrence become complicated because these can depend on the type of behavior and specific locations. Here, we considered how solutions and new technologies could reduce the adverse effects of anthropogenic light.

Recent reports of drastic declines in insect populations have raised global concerns about their conservation. Light pollution is a near inseparable feature of human-altered landscapes and is a potential contributing factor to insect declines.

En ville, la mésange charbonnière privilégie l'odorat pour trouver son alimentation, malgré la pollution, alors que celle des champs se repose plus sur la vision, selon une étude qui souligne la capacité d'adaptation de ce volatile à un milieu urbain.

Originaire des montagnes de Chine, le ginkgo présente des caractéristiques hors du commun. Il résiste bien à la sécheresse et aux pollutions et s’avère donc bien adapté au milieu urbain.
