In this review, we summarize the state of knowledge of the influence of light on the activity and physiology of elasmobranchs (sharks, skates, rays, and sawfish). These are a diverse group with great economic and ecological importance. The long-term success of a species is largely determined by its ability to respond to changes in its environment. ...
The influence of human activities on bird song has been deeply investigated. However, disentangling the relative influence of different anthropogenic pressures (e.g., artificial lights at night, traffic noise, landscape artificialization), of landscape composition (e.g., surface of natural habitat, landscape richness and diversity) and of biotic co...
Les écosystèmes aquatiques urbains sont soumis à une multitude de stress anthropiques et hébergent des communautés fragilisées. La lumière artificielle nocturne (ALAN : Artificial light at night) provoque de nombreux dommages sur les écosystèmes aquatiques (Gaston et al. 2014) : changement dans la composition des communautés végétales (Grubisic et ...
La notion d’environnement nocturne émerge à la suite de la requalification de la lumière artificielle nocturne en pollution lumineuse. Elle entend caractériser les systèmes humains et non humains fonctionnellement liés à l’obscurité. Contrairement à la notion de pollution lumineuse, elle oblige à penser conjointement les multiples enjeux du couple ...
L’éclairage public représente un des premiers postes de consommation d’électricité des collectivités territoriales et s’est imposé ces dernières années comme un enjeu environnemental majeur, en raison des effets sur l’environnement et la santé qu’il génère. De nombreuses études ont démontré le caractère fragmentant de l’éclairage artificiel et ses ...

It is crucial for living organisms to be in synchrony with their environment and to anticipate circadian and annual changes. The circadian clock is responsible for entraining organisms’ activity to the day-night rhythmicity. Artificial light at night (ALAN) was shown to obstruct the natural light cycle, leading to desynchronized behavioral patterns...
Ljusföroreningar är ett stort framväxande problem och då fladdermöss oftast är nattaktiva erfaras de ingå i den taxa som påverkas mest. LED-belysning blir allt vanligare i gatubelysning och utstrålar bland annat inget UV-ljus jämfört med traditionella ljuskällor som utstrålar UV-ljus och därmed förändrar insekters- och potentiellt fladdermössens be...
Disentangling the relative influence of different anthropogenic pressures, landscape composition and biotic conditions on birdsong from species to community levels is challenging. On the basis of a field survey conducted on a breeding bird community in France, we measured the influence of such factors on the timing of birdsongs along an urbanizatio...
Background: Light pollution could represent one of the main drivers behind the current biodiversity erosion. While the effects of many light components on biodiversity have already been studied, the influence of flicker remains poorly understood. The determination of the threshold frequency at which a flickering light is perceived as continuous by ...

Artificial light at night (ALAN) disrupts biological rhythms across widely diverse organisms. To determine how energy is allocated by animals in different light environments, we investigated the impacts of ALAN on behavior and physiology of diurnal green anole lizards (Anolis carolinensis). Two groups of 24 adult lizards (half males, half females) ...
