The Mojave Desert
Transcript of The Mojave Desert
the driest type of desert. Also this area is very hot and sandy. (90-100 degrees in summer) 35 N, 116 W Touches California, Nevada, and New Mexico Joshua Tree Mojave Aster
Can grow up to 30 inches high.
Its flowers have narrow purple to light purple rays surrounding a yellow circle. The flower can grow up to 2 inches in diameter.
After flowering, the plant dies back.
Grows in the Sonoran, Great Basin and Mojave deserts of southeastern California.
Grows in the cold Great Basin, the hotter Mojave, and the very dry Sonoran Desert. This shows it's ability to adapt to climate. The Joshua Tree got its name from the Mormon pioneers who thought the tree reminded them of Joshua, from the old testament of the Bible.
The unusual Joshua Tree grows in Joshua Tree National Park in California and in the Joshua Forest Parkway in western Arizona.
They often grow in groups called groves.
The Joshua Tree has two sets of root systems, one stores any surplus water and it also develops bulbs. The other set is a shallow root system and the shallow roots only reach down to a couple of feet. The spiny leaf of the Joshua Tree is turned upwards in hopes it will catch any moisture in the air. Then it stores the water in the limbs and trunk. Brittle Bush Common plant of the Mojave and Sonoron deserts.
Small shrub, roundish mound that is 2 to 5 feet high.
Many desert plants have this kind of hairy leaf. The hairs form a blanket over the leaves and act an insulating layer against the heat and cold. They also trap any moisture that is in the air and reduce the amount of water lost to dry air.
Likes to grow in dry slopes and washes.
In most of these areas, the brittle bush and creosote bush dominate the vegetation. Triangle-Leaf Bursage Once it is established, it provides a microhabitat for the seedlings of other species and protects them from herbivores with its tangle of branches. Native plant of the Sonoran Desert and can be found throughout southwestern Arizona, the Sonoran Desert, California, and Mexico.
Grows at altitudes of 1,000 to 3,000 feet on open flat, spaces, and steep, gravel hillsides.
Prefers to grow in coarse soils with a high PH rain Creosote Bush Grows very abundantly.
Some bushes are thought to be thousands of years old.
Has small (1-2 inch) pointy green leaves that are covered with a varnish.
Has flowers that also grow along the stems. These flowers are yellow and about the same size of the leaves.
Fruit is small and round with gray or white hairy tufts growing from them. Coyotes Coyotes eat mice, rats, ground squirrels, and other small desert animals.
Hunt in packs sometimes to catch food.
Can hunt at night or day Cited Sources Digital-desert.com
Hyperphysics.phy Kangaroo Rat These animals are granivorous (feed on grain)
Creates burrows to protect itself from predators
Able to get water by taking the moisture out of the air and food. Mountain Lion Can go a long time without any drinking water.
80% of their yearly diet is mule deer.
Uses scent tracking to find food. Mule Deer Grazes on a large variety of plants.
Active day or night making eating easier because of its different options.
Drinks over 2 quarts of water in a day. Golden Eagle Nest height varies, though most are found on cliffs.
Eats rodents and lagomorphs
Moves down-slope from nest during winter Energy Pyramid The creosote bush plays an important role to the kangaroo rat. it is able to hide by using this common bush. since they are so common, they are an easy hiding place to get to. Mexican Spotted Owl The Mexican spotted owl is one of the many endangered species in the Mojave Desert. Only about 2,000 remain in the United States, less in Mexico.
The loss of their original habitat is the main reason for their endangerment. If the forest they lived in wasn't taken away they wouldn't be endangered. My Plan: If we could stop taking animal's habitats and use what we already have, endangerment would not be a problem. Cellular Respiration All living cells must do this. Its the process by which the chemical energy of food molecules is released and provides energy for the essential processes. The energy helps other plants/animals. Photosynthesis is the process of a plant using energy from the sun to make chlorophyll, or plant food. Then it gives off oxygen after making the chlorophyll.
