In modern society the night sky is lit up not only by moon but also artificial light devices. Both of these sources can have a major impact on wildlife physiology and behaviour. For example, number bird species were found to sleep several hours less under full compared new similar sleep-suppressing effect has been reported for at (ALAN). Cloud cover modulate levels perceived wildlife, yet, in o...

Light cycles and predatory threat define activity patterns (e.g. feeding/sleeping, activity/rest) in most diurnal fish species. Artificial light at night (ALAN) may disrupt natural biochemical processes, a mismatch which can eventually reduce condition fitness. We evaluate the separate joint effects of ALAN predator on metabolism within brain, liver muscle tissue common, wild caught damselfish,...

Synopsis The use of artificial light at night (ALAN) is increasing exponentially worldwide and there growing evidence that ALAN contributes to the decline insect populations. One most conspicuous ecological effects strong attraction flying insects. In several studies, sources with short-wavelength emissions have been shown attract highest numbers Furthermore, stages aquatic insects are reported...
