In short, it implies that #LightPollution is decreasing the efficiency with which #plants remove carbon from the atmosphere. It concludes that artificial light at night increases “ #ecosystem respiration” (plants, microbes, and animals releasing carbon dioxide through their activity and growth), but there is no corresponding increase in #photosynthesis.

The result is that plants exposed to ALAN emit more #carbon than they absorb from the #atmosphere. The authors write: “Our findings show that ALAN disrupts the fundamental energetic constraints on ecosystem metabolism, warranting the inclusion of light pollution in global change and carbon–climate feedback assessments.”

CAM #photosynthesis discovered in carnivorous plants
https://phys.org/news/2025-11-cam-photosynthesis-carnivorous.html

"Most #CarnivorousPlants colonize wet, nutrient-poor habitats such as #bogs or #swamps. One of the few exceptions is the genus #Pinguicula... they thrive on rocky soils that are very dry for at least half of the year... Until now, it was unknown how the #plants compensate for the lack of water and still have enough to produce the sticky mucilage... in CAM, the stomata of the leaves remain closed during the day"
