--- _id: '12218' abstract: - lang: eng text: Artificial light at night significantly alters the predictability of the natural light cycles that most animals use as an essential Zeitgeber for daily activity. Direct light has well-documented local impacts on activity patterns of diurnal and nocturnal organisms. However, artificial light at night also contributes to an indirect illumination of the night sky, called skyglow, which is rapidly increasing. The consequences of this wide-spread form of artificial night light on the behaviour of animals remain poorly understood, with only a few studies performed under controlled (laboratory) conditions. Using animal-borne activity loggers, we investigated daily and seasonal flight activity of a free-living crepuscular bird species in response to nocturnal light conditions at sites differing dramatically in exposure to skyglow. We find that flight activity of European Nightjars (Caprimulgus europaeus) during moonless periods of the night is four times higher in Belgium (high skyglow exposure) than in sub-tropical Africa and two times higher than in Mongolia (near-pristine skies). Moreover, clouds darken the sky under natural conditions, but skyglow can strongly increase local sky brightness on overcast nights. As a result, we find that nightjars' response to cloud cover is reversed between Belgium and sub-tropical Africa and between Belgium and Mongolia. This supports the hypothesis that cloudy nights reduce individual flight activity in a pristine environment, but increase it when the sky is artificially lit. Our study shows that in the absence of direct light pollution, anthropogenic changes in sky brightness relieve nightjars from visual constraints on being active. Individuals adapt daily activities to artificial night-sky brightness, allowing them more time to fly than conspecifics living under natural light cycles. This modification of the nocturnal timescape likely affects behavioural processes of most crepuscular and nocturnal species, but its implications for population dynamics and interspecific interactions remain to be investigated. article_number: '165760' author: - first_name: Ruben full_name: Evens, Ruben last_name: Evens - first_name: Michiel full_name: Lathouwers, Michiel last_name: Lathouwers - first_name: Jean-Nicolas full_name: Pradervand, Jean-Nicolas last_name: Pradervand - first_name: Andreas full_name: Jechow, Andreas last_name: Jechow - first_name: Christopher Conrad Maximillian full_name: Kyba, Christopher Conrad Maximillian last_name: Kyba - first_name: Tom full_name: Shatwell, Tom id: '86424' last_name: Shatwell orcid: 0000-0002-4520-7916 - first_name: Alain full_name: Jacot, Alain last_name: Jacot - first_name: Eddy full_name: Ulenaers, Eddy last_name: Ulenaers - first_name: Bart full_name: Kempenaers, Bart last_name: Kempenaers - first_name: Marcel full_name: Eens, Marcel last_name: Eens citation: ama: 'Evens R, Lathouwers M, Pradervand JN, et al.

We applied a two-dimensional hydrodynamic model to explore the response of the thermal structure in Germany's largest drinking water reservoir, Rappbode Reservoir, to future climate projections and different water withdrawal strategies. We used projections for representative concentration pathways (RCP) 2.6, 6.0 and 8.5 from an ensemble of 4 different global climate models. Simulation results showed that epilimnetic water temperatures in the reservoir strongly increased under all three climate scenarios. Hypolimnetic temperatures remained rather constant under RCP 2.6 and RCP 6.0 but increased markedly under RCP 8.5. Under the intense warming in RCP 8.5, hypolimnion temperatures were projected to rise from 5 °C to 8 °C by the end of the century. Stratification in the reservoir was projected to be more stable under RCP 6.0 and RCP 8.5, but did not show significant changes under RCP 2.6. Similar results were found with respect to the light intensity within the mixed-layer. Moreover, the results suggested that surface withdrawal can be an effective adaptation strategy under strong climate warming (RCP 8.5) to reduce surface warming and avoid hypolimnetic warming. This study documents how global scale climate projections can be translated into site-specific climate impacts to derive adaptation strategies for reservoir operation. Moreover, our results illustrate that the most intense warming scenario, i.e. RCP 8.5, demands far-reaching climate adaptation while the mitigation scenario (RCP 2.6) does not require adaptation of reservoir management before 2100. article_number: '141366' author: - first_name: Chenxi full_name: Mi, Chenxi last_name: Mi - first_name: Tom full_name: Shatwell, Tom id: '86424' last_name: Shatwell orcid: 0000-0002-4520-7916 - first_name: Jun full_name: Ma, Jun last_name: Ma - first_name: Yaqian full_name: Xu, Yaqian last_name: Xu - first_name: Fangli full_name: Su, Fangli last_name: Su - first_name: Karsten full_name: Rinke, Karsten last_name: Rinke citation: ama: 'Mi C, Shatwell T, Ma J, Xu Y, Su F, Rinke K.
