Effects of anthropogenic light on species and ecosystems

Effects of anthropogenic light on species and ecosystems | Biodiversité | Scoop.it

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.

Local ecological knowledge reveals combined landscape effects of light pollution, habitat loss, and fragmentation on insect populations - ScienceDirect

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.

Biodiversity impacts and conservation implications of urban land expansion projected to 2050

Biodiversity impacts and conservation implications of urban land expansion projected to 2050 | Biodiversité | Scoop.it
Understanding the impacts of urbanization and the associated urban land expansion on species is vital for informed urban planning that minimizes biodiversity loss. Predicting habitat that will be lost to urban land expansion for over 30,000 species under three different future scenarios, we find that up to 855 species are directly threatened due to unmitigated urbanization. Our projections pinpoint rapidly urbanizing regions of sub-Saharan Africa, South America, Mesoamerica, and Southeast Asia where, without careful planning, urbanization is expected to cause particularly large biodiversity loss. Our findings highlight the urgent need for an increased focus on urban land in global conservation strategies and identify high-priority areas for this engagement.

Le hamster commun en milieu urbain : comment vivre en ville quand on vient des champs ? CNRS

Le hamster commun en milieu urbain : comment vivre en ville quand on vient des champs ? CNRS | Biodiversité | Scoop.it

Le hamster commun (Cricetus cricetus) est une espèce menacée d’extinction qui vit en milieu agricole mais parfois également en ville. L’une de ces populations urbaines est implantée depuis de nombreuses années à Vienne en Autriche. A travers le projet LIFE+ALISTER et en collaboration avec l’Université de Vienne, une équipe du CNRS s’est intéressée à l’activité du hamster dans l’environnement urbain : elle a exploré son organisation et les différences intersexuelles existantes. La particularité de cette étude est une approche basée intégralement sur l’observation comportementale amenant ainsi des pistes nouvelles pour la conservation de l’espèce.
