All cacti have some adaptations to promote efficient water use. Most cacti— opuntias and cactoids —specialize in surviving in hot and dry environments (i.e. are xerophytes ), but the first ancestors of modern cacti were already adapted to periods of intermittent drought. [ 10 ]
A xerophyte (from Greek ξηρός xeros 'dry' + φυτόν phuton 'plant') is a species of plant that has adaptations to survive in an environment with little liquid water. . Examples of xerophytes include cacti, pineapple and some gymnosperm pl

Saguaro cacti and agave have both suffered in sweltering weather this summer and last. Ecologists are working to figure out how various species respond to the persistent extreme heat and pinpoint ...
Stenocereus thurberi, the organ pipe cactus, [3] is a species of cactus native to Mexico and the United States. The species is found in rocky desert. Two subspecies are recognized based on their distribution and height. The Organ Pipe Cactus National Monument is named for the species. Cacti are minimally adapted to particular thermal niches ...
Arizona's saguaro cacti, a symbol of the U.S. West, are leaning, losing arms and in some cases falling over during the state's record streak of extreme heat, a scientist said on Tuesday. Summer ...
The typical habitat is hot and very arid, and the plants have adapted to exploit water movement to concentrate their biomass in areas where water is likely to be present. Like Sclerocactus , Ferocactus typically grow in areas where water flows irregularly or depressions where water can accumulate for short periods of time.
[1]: 2–3 The flora of the Colorado Desert are influenced by the environment of the very dry and hot lower areas of the Colorado River valley, which may be barren, treeless, and generally have no large cacti. [1]: 3 Flora of the Arizona Upland are comparatively lush, with trees and large columnar cacti that can withstand winter frosts.
