Moonlight shapes how some animals move, grow and even sing sciencenews.org Jul 8, 2019 10 facts
claimDuring the Arctic winter, when the sun is absent, zooplankton continue to perform vertical migrations directed by moonlight rather than sunlight.
claimEscarabaeus satyrus beetles use moonlight as a compass to navigate away from dung pats after sculpting dung into balls.
claimMoonlight, independent of the moon's gravitational effects on tides, influences animal reproduction, foraging, communication, and other behaviors.
claimEscarabaeus satyrus beetles use moonlight as a compass to navigate at night in South African grasslands.
measurementThe earlier start time caused by moonlight lengthens the average song period of male white-browed sparrow weavers by 67 percent.
claimThe lunar cycle, specifically the presence or absence of moonlight, influences animal reproduction, foraging, communication, and other physiological and behavioral aspects.
claimEscarabaeus satyrus beetles navigate by detecting polarized moonlight, which is created when lunar light scatters off gas molecules in the atmosphere.
claimLantern fish, which are likely predators, avoid moonlight to evade larger fish that hunt using light.
claimMoonlight influences the behavior of animals that are active during the daytime.
claimDung beetles use the polarization signal of moonlight to navigate, with the strength of this signal weakening as the moon gets darker across the lunar cycle.

measurementPhotoreduction, a light-induced chemical reaction in the L-Cry protein, occurs after four hours of exposure to dim moonlight and reaches a maximum after six hours of continuous exposure.
claimThe L-Cry protein can respond to light intensities spanning five orders of magnitude, allowing it to react to both strong sunlight and dim moonlight due to the differing light sensitivity of its two flavin structures.
claimIn marine bristleworms, moonlight conditions cause only one of two flavin molecules to be photoreduced, whereas bright light causes both flavin molecules to be photoreduced quickly.
claimScientists state that while the L-Cry protein is essential for discriminating between sunlight and moonlight in marine bristleworms, other light-sensing molecules are also involved.
claimThe authors of a 2022 report conclude that the L-Cry protein mechanism in marine bristleworms functions as a highly sensitive low-light sensor for moonlight detection and a less sensitive high-light sensor for sunlight detection.
claimMarine bristleworms use a six-hour window of moonlight exposure during a full moon to synchronize their spawning with monthly lunar cycles.
claimBristle worms require the ability to distinguish between sunlight and moonlight to synchronize spawning with the moon's roughly 29.5-day cycle.

measurementSome North American songbirds exhibit similar reactions to moonlight as white-browed sparrow weavers, with earlier start times lengthening their average singing period by 67 percent.
claimScientists concluded that moonlight triggers earlier singing in white-browed sparrow weavers, as males maintained their normal schedule when the full moon was below the horizon at dawn.
claimMoonlight influences animal behavior, including reproduction, foraging, and communication, by changing the brightness of the night landscape.
claimSome species of dung beetles are active at night and utilize moonlight as a compass for navigation.
claimShima hypothesizes that bright moonlight allows triplefin larvae to better see and consume plankton, while also providing a 'night-light' effect that allows them to relax, as predators like lantern fish avoid moonlight to evade larger predators.
claimMoonlight directs the daily vertical migrations of zooplankton in the Arctic during the sunless winter, contradicting previous scientific assumptions that these migrations ceased during that time of year.
3 ways the moon affects wildlife discoverwildlife.com 6 facts
claimNocturnal animals use moonlight to hunt or forage more easily, though this increases their risk of being hunted.
claimThe African dung beetle species Scarabaeus zambezianus uses moonlight to collect dung efficiently.
claimEphedra foemina attracts nocturnal insects like beetles by producing droplets of fluid that reflect moonlight, creating a sparkling effect under polarizing light.
claimNocturnal animals use moonlight as an orientation cue at night.
claimSandhoppers possess the ability to distinguish between sunlight and moonlight, allowing them to navigate correctly regardless of the time of day.
claimMoonlight is reflected sunlight.

claimThe dung beetle Scarabaeus zambesianus uses the polarisation pattern of moonlight and its scattering through the atmosphere to navigate in a straight line to its burrow.
claimResearch conducted in a laboratory in Sweden demonstrated that when dung beetles were placed under non-polarising artificial light, they travelled in circles rather than straight lines, indicating a reliance on moonlight polarisation patterns for orientation.
claimEphedra foeminea produces droplets of fluid on its cones in bright moonlight, which sparkle under the polarising light of the Moon to attract beetles and other nocturnal insects for pollination.
claimSpecies that exhibit nocturnal behaviors dependent on moonlight are negatively impacted by global light pollution, which obscures the moonlight they rely on.

claimNumerous insect species, such as moths, use moonlight to stabilize their flight paths and maintain consistent trajectories.
claimThe bristle worm Platynereis dumerilii contains a protein with light-absorbing flavin structures that differentially detect moonlight and sunlight.
claimThe L-Cry protein in the bristle worm Platynereis dumerilii can distinguish between sunlight and moonlight through the differential activity of two protein strands containing flavins.
