Artificial light at night has rapidly increased during the last century, and could potentially affect many ecological processes, from individuals via communities to entire ecosystems. Recent research shown that artificial may not only behaviour of animals but also growth plants vegetation composition. However, it is known yet whether other global change components such as plant invasions. Here,...

Light pollution is known to affect important biological functions of wild animals, including daily and annual cycles. However, knowledge about long-term effects of chronic exposure to artificial light at night is still very limited. Here we present data on reproductive physiology, molt and locomotor activity during two-year cycles of European blackbirds (Turdus merula) exposed to either dark ni...

Because visual predation occurs day and night, many predators must have good night vision. Prey therefore exhibit antipredator behaviours in very dim light. In the field, the giant Australian cuttlefish (Sepia apama) assumes camouflaged body patterns at night, each tailored to its immediate environment. However, the question of whether cuttlefish have the perceptual capability to change their c...

The growing global prevalence of energy efficient broad spectrum lighting threatens to disrupt an array visually guided ecological processes. Broad likely better enables the discrimination colour, yet it is potential increase conspicuousness camouflaged prey at night remains little explored. Using a well-established visual model, we quantified impacts four spectrally distinct narrow and technol...

Imaging air Cherenkov telescopes are usually triggered on a coincidence of two or sometimes more pixels, with discriminator thresholds in excess of 20 photoelectrons applied for each pixel. These thresholds required to suppress night-sky background are significantly higher than expected on the basis of a Poisson distribution in the number of night-sky photoelectrons generated during the charact...
