North American desert flora

than 250 members worldwide, many of which are native to desert regions. Creosote bush is abundant in three of the four North American deserts, i.e. the Mojave, the Sonoran, and the Chihuahuan Deserts. In the United States, L. tridentata occurs in the states of Arizona, California, Nevada, New Mexico, Texas, and Utah. Most Agassiz’s desert tortoises, Gopherus agassizii, regardless of the specific locality they inhabit, live in a type of desert biome known as creosote bush scrub. Dominated by the creosote

1. The Sonoran Desert The term desert is strongly connected to the image of an extremely harsh environment void of any life. The sand dunes at the Gulf of California would fit this description of a desert biome, but for large parts the Sonoran Desert has a stunning array of different organisms. The defining character of a desert is usually low levels of rainfall with under 25 cm per year. Additional to that, the relationship between rainfall and the evaporated and transpired water must be taken

civilization has its unique origins and the Native Americans are no exception. While the origins and history of many Asian and European countries are well known, the origins of Native Americans are not. Many theories exist about how the Native Americans’ ancestors arrived in North America but the widely accepted theory is the one I will discuss. Traditional Native American history tells that Native Americans have always inhabited the North American Continent since the beginning of time, but this

Desert Vegetation Desert flora have adapted to combat extreme weather conditions. The various types of plants have micro evolved to survive in the heat, along with other environmental deficits. The physical and behavioral adaptions have allowed these plant species to flourish. It’s important to understand the plants adaptations to the climate and environment, as well as the medical uses and dangers of these plants. The various vegetation within the desert biome have overcome the dry climate and

Over the centuries, Colorado’s climate has changed significantly to mountains, seas, deserts, and tropics. All of which are coming and going with the changing climate and the shifting tectonic plates. Because of these significant changes, Colorado was a much different place 250 million years ago. With the tectonic plates moving, we see the climate getting colder to the North Pole and warmer to the South where the equator lies. Furthermore, Colorado throughout the years has experienced a series of

Forests are an irreplaceable part of Earths ecosystem. Every forest is unique due to flora and fauna which houses it. They are homes for many species from simple bacteria to big carnivore animals. Forests absorb carbon dioxide and provide oxygen and is a great place for recreation and biological studies. Temperate forest of northeast United States is an example of rich diversity and harmony of plants and animals. Unfortunately, constant growing of human population and demand for more land

many more well defined ecosystems. Do you know the most important biomes? The Desert biome is one of the important biomes in the world, it covers about one fifth of the world’s surface, averages less than 50cm/year , and is one of the driest places in the world. Although most deserts, such as the Sahara of the North Africa and the deserts of the southwestern U.S., Mexico, and Australia, has low latitudes. Most deserts have a considerable amount of specialized vegetation, as well as specialized

plastic in 1862 will turn nowadays as an ecological catastrophe? In August 1997, after a regatta in Honolulu Capitan Charles Moore, today is scientific and researcher, decided to safe time and sailed straight to California through the North Pacific Gyre, a giant watery desert without any wind. He was terrified by the view that he saw around his yacht, which navigated through infinite debris of floating plastic, hundred of miles across to the horizon. Thus was discovered the “Great Pacific Garbage Patch”

Question: What management strategies have been implemented in response to the resilience and vulnerability of a selected ecosystem? The Mojave Desert is a world famous desert that occupies a significant amount of California and smaller parts in surrounding states. Covering thousands of square kilometers, the ecosystems can range from 100 meters below sea level up to 2000 meters above sea level. The biophysical interactions within these ecosystems such as earth movements, soil formation, weather and

states. The four corner states include : Colorado, Utah, Arizona, and New Mexico. Arizona is well known for the Grand Canyon State Park. This state has the most land dedicated to Native Americans in the entire US. Arizona summers are very hot while the winters are mild. Southern Arizona is well known for its dry desert climate. Northern Arizona demonstrates a different climate. The Northern section consists of forests of pine, Douglas fir, and spruce trees. It is also home to the Colorado Plateau and
