The nighttime is undergoing unprecedented change across much of the world, with natural light cycles altered by introduction artificial emissions. Here we review extent and dynamics at night (ALAN), benefits that ALAN provides, environmental costs creates, approaches to mitigating these negative effects, how are likely in future. We particularly highlight consequences increasingly widespread use light-emitting diode (LED) technology for new lighting installations retrofit pre-existing ones. Although this has been characterized as a technological revolution, it also constitutes revolution impacts ALAN, because LEDs commonly used outdoor have significant emissions blue wavelengths which many biological responses sensitive. It clear very different approach required.

Published: April 1, 2023

How the relative impacts of anthropogenic pressures on natural environment vary between different taxonomic groups, habitats, and geographic regions is increasingly well established. By contrast, times day at which those are most forcefully exerted or have greatest influence not understood. The impact nighttime bears particular scrutiny, given that for practical reasons (e.g., researchers themselves belong to a diurnal species), studies conducted during daytime organisms predominantly active in ways do differentiate nighttime. In present article, we synthesize current state knowledge environment, highlighting key findings examples. evidence available suggests under intense stress across increasing areas world, especially from pollution, climate change, overexploitation resources.

Small pelagic fish, including anchovies, sardines and sardinellas, mackerels, capelin, hilsa, sprats herrings, are distributed widely, from the tropics to far north Atlantic Ocean southern oceans off Chile South Africa. They most abundant in highly productive major eastern boundary upwelling systems characterised by significant natural variations biomass. Overall, small fisheries represent about one third of global fish landings although a large proportion catch is processed into animal feeds. Nonetheless, some developing countries addition their economic value, also make an important contribution human diets food security many low-income households.

The exploitation and utilization of resources in marine environments have ignited a demand for advanced illumination optical communication technologies. Light-emitting diodes (LEDs), heralded as "green lighting sources", offer compelling solution to the technical challenges exploration due their inherent advantages. Among myriad LED technologies, phosphor-converted light-emitting (pc-LEDs) emerged frontrunners applications. At heart pc-LEDs lie phosphor materials, colour-converters that orchestrate emission light. In environment, blue-green light with wavelength 440-570 nm exhibits deepest penetration depth, while other wavelengths are rapidly attenuated shallow layer. Additionally, specific crucial particular However, moist environment well continuous stable pose formidable challenge environmental stability phosphors.

Opposing Visual Impairments Induced by Structurally Similar Organophosphate Flame Retardants TPHP and CDP in Zebrafish Larvae

Environmental Science & Technology, Journal Year: 2025, Volume and Issue: unknown

Published: April 23, 2025

Vision is the primary sensory function for most animals and also a sensitive toxic target of environmental pollutants. A new class organophosphate flame retardants (OPFRs) termed emerging OPFRs (eOPFRs) with limited toxicological information rapidly developed into substitutes traditional OPFRs. In this study, we investigated visual toxicity triphenyl phosphate (TPHP, one OPFR) cresyl diphenyl (CDP, on zebrafish larvae at environmentally relevant concentrations (3 30 nM). After 5 days exposure, an opposite was found between two OPFRs, manifested in light perception gene expressions opsins. CDP caused weak reaction to overall inhibition opsin expression (0.7- 0.8-fold) larvae, while TPHP tended stimulate these events (1.2- 2.4-fold). Besides, identified key transcription factor, tbx2a, that significantly disrupted both OPFRs' exposure. The differing ways which bind Tbx2a may be reason behind their effects. These findings provided clues mechanisms revisited question regarding safe those contaminants.
