As climate change brings more severe heat, it is testing iconic desert plants known to thrive in harsh environments, including saguaro cacti and agave.
The prickly mysterious giant grows in the desolate Sonoran desert covering southern Arizona and northern Mexico, but it might be in jeopardy. Daniel Winkler, research ecologist with the United ...
Saguaros did not evolve in an environment with frequent fires, thus are not adapted to fire survival. Most Sonoran desert ecosystems have a fire return interval greater than 250 years; buffelgrass thrives at fire return intervals of two to three years. This has led to the reshaping of the Sonoran Desert ecosystem and threatens the survival of ...
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 ...
Climate change will likely impact the future distribution of numerous plant species, including Pachycereus pringlei, which can be attributed to alterations in precipitation and temperature. [ 4 ] The cactus fruits were always an important food for the Seri people, in Sonora; the dried cactus columns themselves could be used for construction ...
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
[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.
The effects of climate change on plant biodiversity can be predicted by using various models, for example bioclimatic models. [5] [6] Habitats may change due to climate change. This can cause non-native plants and pests to impact native vegetation diversity. [7]
