| Abstract |
Many broadcast spawning corals in multiple reef regions release their gametes with incredible temporal precision just once per year, using the lunar cycle to set the night of spawning. Moonlight, rather than tides or other lunar-regulated processes, is thought to be the proximate factor responsible for linking the night of spawning to the phase of the Moon. We compared patterns of gene expression among colonies of the broadcast spawning coral Acropora millepora at different phases of the lunar cycle, and when they were maintained under one of three experimentally simulated lunar lighting treatments: i) lunar lighting conditions matching those on the reef, or lunar patterns mimicking either ii) constant full Moon conditions, or iii) constant new Moon conditions. Normal lunar illumination was found to shift both the level and timing of clock gene transcription cycles between new and full moons, with the peak hour of expression for a number of genes occurring earlier in the evening under a new Moon when compared to a full Moon. When the normal lunar cycle is replaced with nighttime patterns equivalent to either a full Moon or a new Moon every evening, the normal monthlong changes in the level of expression are destroyed for most genes. In combination, these results indicate that daily changes in moonlight that occur over the lunar cycle are essential for maintaining normal lunar periodicity of clock gene transcription, and this may play a role in regulating spawn timing. These data also show that low levels of light pollution may have an impact on coral biological clocks. |

| Abstract |
With the rapid development of solid state lighting technology and the availability of LED light sources, coupled with the benefits they offer such as energy efficiency, long lifespan and the fact that they can be controlled and programmed, we are now finding LEDs being more widely used for animated advertising. In spite of the pace at which SSL is developing, or perhaps because of this, there is a distinct lack of evaluation guidelines or recommendations for professional designers. It is therefore essential that more research is carried out on this issue on an international scale, and that experts in the field get their heads together in order to formulate some basic guidelines that can be applied in practice. |

| Abstract |
La question de l’éclairage urbain nocturne est posée publiquement de manière de plus en plus significative, d’abord aux États-Unis puis en Europe. Cantonnée à l’origine au domaine de l’astronomie, cette question pose problème dans différents secteurs : l’environnement, la santé, l’urbanisme, mais aussi et surtout l’énergie... En croisant une approche sociologique avec une approche géographique, les auteurs font le récit d’une controverse environnementale aboutissant, en France, à l’inscription de la notion de pollution lumineuse dans la loi Grenelle et questionnent sa dimension spatiale. Ils montrent les différentes logiques et interprétations, à l’œuvre autour de la distinction entre « pollution » et « nuisance » lumineuses, qui traversent les scènes de négociation sur les processus de normalisation et la mobilisation d’outils de zonage. |

| Abstract |
Anthropogenic environmental impacts can disrupt the sensory environment of animals and affect important processes from mate choice to predator avoidance. Currently these effects are best understood for auditory and chemo-sensory modalities and recent reviews highlight their importance for conservation. Here we summarise how anthropogenic changes to the visual environment (ambient light, transmission, backgrounds) affect visual communication and camouflage, and highlight implications for conservation. These implications are particularly evident for disrupted camouflage due to its tight links with survival while the conservation importance of impaired visual communication is less well-documented. Such effects can be potentially severe when they affect critical processes such as pollination or species recognition. However, when impaired mate choice does not lead to hybridization, the conservation consequences are less clear. We suggest that the demographic effects of human impacts on visual communication and camouflage will be particularly strong when: (a) human-induced modifications to the visual environment are evolutionary novel, that is, very different from natural variation, (b) affected species and populations have low levels of intraspecific (genotypic and phenotypic) variation and low levels of behavioural, sensory or physiological plasticity and (c) the processes affected are directly related to survival (camouflage), species recognition, or number of offspring produced, rather than offspring quality or attractiveness. The evidence summarized here suggests that anthropogenic effects on the visual environment might be of similar conservation concerns as those on other sensory modalities.
