“…Currently, about 80% of people live under light-polluted skies [ 7 ], and light pollution increases by up to 10% per year [ 8 ], posing a serious threat to biodiversity and human health. Light pollution in cities substantially exceeds the level that can be experienced under a moonlight maximum (ca.…”

The circadian rhythms evolved to anticipate and cope with cyclic changes in environmental conditions. This adaptive function is currently compromised by increasing levels of artificial light at night (ALAN), which can represent a risk for the development of diseases of civilisation. The causal links are not completely understood, and this featured review focuses on the chronodisruption of the neuroendocrine control of physiology and behaviour by dim ALAN. The published data indicate that low levels of ALAN (2–5 lux) can attenuate the molecular mechanisms generating circadian rhythms in the central oscillator, eliminate the rhythmic changes in dominant hormonal signals, such as melatonin, testosterone and vasopressin, and interfere with the circadian rhythm of the dominant glucocorticoid corticosterone in rodents. These changes are associated with a disturbed daily pattern of metabolic changes and behavioural rhythms in activity and food and water intake. The increasing levels of ALAN require the identification of the pathways mediating possible negative consequences on health to design effective mitigation strategies to eliminate or minimise the effects of light pollution.

“…Paradoxically, as lighting becomes more efficient (e.g., the emergence of light-emitting diodes, LEDs), so does the severity and scope of ALAN's negative impacts (Schulte-Römer et al, 2019) documented in a growing number of research studies on ALAN and light pollution in recent years (Burt et al, 2023). Citizen science data have revealed that globally, sky glow from artificial light has increased at a rate higher than was previously known through satellite data, showing that the brightness of the sky has increased at up to 10% per year (Kyba et al, 2023). Unequivocally, there are considerable ecological considerations of ALAN; roughly 60% (n = 638,000) of invertebrate and 30% (n = 17,000) of vertebrate species have nocturnal phases of their life cycle (Hölker et al, 2010).…”

The overuse and expansion of artificial light at night (ALAN) has emerged from complex social, economic, and political factors, making it a societal problem that negatively impacts wildlife and people. We propose that a convergence research approach combining ecological forecasting with community engagement and public policy is needed to address this diverse societal problem. To begin this convergence research approach, we hosted a workshop to strengthen connections among key biodiversity‐oriented ALAN stakeholders and to better understand how stakeholder groups function across the United States through facilitated discussions. We have prioritized the input of stakeholders early in our research design by including them in the formulation of a national survey on public perceptions surrounding ALAN and received their input on existing ecological forecasting tools to improve those research products for their future use.

“…Understanding the mechanisms behind vertical migration behavior is not only an exciting scientific endeavour but also of high current and future relevance. The vertical migration of pelagic organisms is tightly coupled to diel and seasonal dynamics of surface irradiance levels and both are being subject to future change through accelerating light pollution (Pawson and Bader 2014, Davies et al 2014, Kyba et al 2023, and climate change-induced sea ice retreat in polar habitats (Post et al 2013, Bhatt et al 2014. To this date, it is not known how species will react to the changing light environment, and how behavioral adaptation will shape future species interactions and ecosystem structure.…”

Multifrequency echosounders are versatile devices commonly used in commercial fisheries, fisheries science and biological oceanography for the detection, quantification and even identification of organisms suspended in the underlying water column. They produce data that is rich in information, but can be tedious to process, often relying on expensive commercial software. The aim of our overarching research project was to analyze the vertical distribution of Antarctic krill swarms (Euphausia superba, Dana 1850) in different seasons and regions in order to learn more about their behavioral ecology and ecophysiological adaptation. Therefore, we only required visual information on the distribution of krill swarms as well as metrics that characterize their vertical position. Instead of using storage-intensive raw acoustic data, we developed a simple method to extract the relevant information from screenshots taken automatically on board a commercial krill fishing vessel during its operations. Using screenshots instead of raw data reduced the amount of data by a factor of >1000 (3 TB of raw data vs. 2.8 GB of screenshots for 8 months of observations) while preserving the information needed to carry out our seasonal behavioral analyses. In this study, we present the workflow and demonstrate that our method produces qualitatively and quantitatively similar results to using raw data, while being much less demanding in terms of computation and data storage. The code for the data processing is written in the open source programming language R, publicly accessible and therefore, provides a useful resource for other scientists interested in the dynamics of vertical biomass distributions from echosounder data.
