The largest desert in North America, the Chihuahuan Desert stretches across six Mexican states and parts of Texas and New Mexico. Local people also rely on cacti for medicinal use, such as a traditional Mexican arthritis treatment. While the desert is generally seen as a "high elevation" desert, its elevation actually varies from 1,000 feet in the Rio Grande valley to 10,000 feet in some of the mountain ranges. Start Over.

Like much of the southwestern United States, the Chihuahuan Desert is marked by the occurrence of mountain ranges and valleys. Soil Profile: 80% of the soil is Calcareous a calcium rich soil from limestone beds. The conversion of Chihuahuan desert shrublands back to grasslands has been attributed by Neilson to the Little Ice Age. While the desert is generally seen as a "high elevation" desert, its elevation actually varies from 1,000 feet in the Rio Grande valley to 10,000 feet in some of the mountain ranges. We review animal studies that focused on spatial patterns in the distribution and ecosystem effects of several taxa and guilds. Ecosystem services estimates have not been published for some biomes, notably desert ecosystems. The Chihuahuan Desert encompasses one of the most biologically diverse arid regions on Earth. Le désert abrite plus de 130 mammifères, 3 000 espèces végétales (dont 1 000 sont endémiques), plus de 500 espèces d’oiseaux et 110 de poissons d’eau douce indigènes. Local people also rely on cacti for medicinal use, such as a traditional Mexican arthritis treatment. Desert ecosystems have long served as model systems in the study of ecological concepts (e.g., competition, resource pulses, top-down/bottom-up dynamics).

Large-scale ecosystem degradation and vegetation changes in the Jornada Basin occurred prior to studies of animal populations (Buffington and Herbel 1965). 561 13 0000002475 00000 n Main threats to the Chihuahuan desert are due to population growth, poor water management, agricultural expansion, invasive species and a lack of understanding about the desert's ecological importance. Because this research focused on the role of animals in ecosystems, studies of animal populations were conducted simultaneously with functional studies. On average, annual precipitation is 250 mm/year (77–507 mm/year) and the mean annual temperature is 14.7°C (13.5–16.3°C).
