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.
claimBristle worms require the ability to distinguish between sunlight and moonlight to synchronize spawning with the moon's roughly 29.5-day cycle.
3 ways the moon affects wildlife discoverwildlife.com 3 facts
Moonlight shapes how some animals move, grow and even sing sciencenews.org Jul 8, 2019 2 facts
claimDuring the Arctic winter, when the sun is absent, zooplankton continue to perform vertical migrations directed by moonlight rather than sunlight.
claimFoster and colleagues evaluated the strength of the polarization signal in the night sky over dung beetle territory and found that the proportion of polarized light during a nearly full moon is similar to that of polarized sunlight during the day, which many daytime insects use to navigate.
Compendium Vol. 5 No. 1: The ecological role of native plants bio4climate.org 2 facts
claimCompetition for sunlight, water, and nutrients drives niche differentiation, which allows species to occupy specific spaces or timing within an ecosystem to access limited resources.
accountResearchers in Shanghai observed high mortality rates among evergreen seedlings in near-natural forests, which they attributed to over-exposure to sunlight.

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.
Evolutionary psychology - Wikipedia en.wikipedia.org 1 fact
claimThe human adaptation for skin to tan is a facultative adaptation that is conditional on exposure to sunlight.
Resolving the evolutionary paradox of consciousness link.springer.com Apr 1, 2024 1 fact
claimThe coolness or warmness of color feelings is likely due to implicit learned associations, where warm-feeling colors (yellows, reds, oranges) are associated with sunlight and fire, and cool-feeling colors (blues and greens) are associated with shadow and water.
Why Sleep Is Important for Brain Health - American Brain Foundation americanbrainfoundation.org Mar 16, 2022 1 fact
claimHuman retinas contain receptors that process different wavelengths of light from both sunlight and artificial sources, which influences sleep-wake cycles, circadian rhythms, metabolism, and energy levels.
The moon has power over animals - Science News Explores snexplores.org Nov 7, 2019 1 fact
measurementThe proportion of polarized light in the night sky during a nearly full moon is similar to the proportion of polarized sunlight during the day, which insects like honeybees use for navigation.
5.9.1: Kingdom Plantae - Evolution and Phylogeny bio.libretexts.org Nov 24, 2025 1 fact
claimThe transition from water to land required plants to develop strategies to avoid dehydration, disperse reproductive cells, support themselves without water, and capture and filter sunlight.
The cross-cultural study of mind and behaviour: a word of caution link.springer.com Apr 8, 2022 1 fact
accountNgöbe informants explain agency attributions by citing observable interactions, such as interpreting plants as thinking because they grow toward sunlight or the sun communicating with water.
How the Full Moon Affects the Behavior of Animals ruhighlander.org May 2, 2024 1 fact
claimA full moon occurs when the most sunlight reflects off the Moon toward Earth, creating an intense glare that makes other celestial objects like stars and planets more difficult to observe.
Plant Nutrition and Sustainable Agriculture - iBiology ibiology.org 1 fact
claimCrop plants require sunlight, carbon dioxide, water, and approximately 50 inorganic nutrients to achieve maximal food production.
Short- and long-term health consequences of sleep disruption dovepress.com May 19, 2017 1 fact
claimExcessive nighttime light pollution and underexposure to daytime sunlight can lead to the disruption of circadian rhythms.
