2024年3月4日 · Like many species of flowering desert cacti, the old man cactus flowers during summer nights. This habit gives it its other common name — queen of the night. But, being a desert plant, the old man cactus thrives in full sun, arid, well-drained ground, and full sunlight.
Desert Biome: Climate, Precipitation, Location, Seasons, Plants ...
Since desert biomes receive little precipitation per year, the conditions are very hostile for plants and animals. A desert biome is a collection of habitats that that develop in arid (dry) environments as a result of little rainfall (50cms per year) or no rainfall at all.

2024年11月8日 · The new analysis showed that since 2000, in 66% of the historical and emerging drought-prone regions, high evaporative demand alone could cause drought, meaning drought can occur even without precipitation deficit. Before 2000, that was only true for 26% of the area. “During the drought of 2020-2022, moisture demand really spiked,” Fu said.
