how do bearded dragons survive in the desert?
956479
DESCRIPTION: \n\nThis unusual mid-sized stocky agamid lizard has prominent spines along its sides and a large, essentially triangle-shaped head. Forming a sort of shield around the snout is a spiney jaw pouch which, when swollen, looks like a beard and makes any predator think twice before attacking. This wide-ranging species shows considerable geographic variation; its basic color varies from shades of brown, gray, and reddish-brown to bright orange. The ventral surface ranges from pale to dark gray, with white elongated spots edged with black. Mature males have dark "beards" which become black during courtship and breeding. Adults can grow as large as ten inches in body length or two feet in total length, including the tail. Males are larger than females. \n\nII. GEOGRAPHICAL RANGE AND HABITAT: \n\nThese lizards are native to Central Australia. They prefer semi-arid to arid woodland habitats. Time is spent both on the ground and in trees. They may be found perched on bush branches and even on fence posts. \n\nIII. DIET:\n\nBearded dragons are omnivorous and consume many types of insects, small vertebrates, and vegetation including fruits and flowers. \n\nIV. LIFE CYCLE/SOCIAL STRUCTURE:\n\nSexual maturity is reached at one to two years of age. Mature females typically lay clutches of eleven to sixteen oblong leathery eggs in early summer. The eggs are laid in nests dug in sandy soil and the unattended young hatch 3 months later. \n\nV. SPECIAL ADAPTATIONS:\n\nA bulky body and the habit of basking allows them to store heat, making it possible to operate at lower temperatures than other lizards. They can also survive higher temperatures for several hours, since they can regulate body temperature by evaporation. \n\nVI. INTERPRETIVE INFORMATION:\n\nWhen intimidated, they flatten their bodies and stand erect with mouth gaping. The light-colored mouth lining, spines bordering the lower jaw and puffed-out blackish beard give a formidable appearance. This defensive display has earned these lizards the common name of "bearded dragon". \nAggressiveness to other members of the group is shown through "body language". The tip of the tail is slightly curved at the end and the head is bobbed rapidly. Submission is signaled by rotating the arms in a full circular motion, which looks a bit like waving. Ritualistic sparring matches take place in which both animals are in flat postures, beards and tails up and outward; they circle each other, biting at one another's tail, but usually no damage is done. \n\nTheir ability to change shades of color, from light to dark, helps them to regulate body temperature. Color changes can also depend on emotional state, and may also be used for concealment. When injured, sick, or dying the back becomes black and the legs pale yellow. \n\nAustralian desert lizards often make their escape by rising on their hind legs and running bipedally. They cannot run as fast as when using four feet, but perhaps this behavior aids in temperature control. They lift their bodies from the hot ground to lose the heat they generate in running. This reduces the amount of heat they take in from the ground and increases the cooling airflow over their bodies.

Ravens, birds that formerly populated mountainous regions, are ubiquitous in the desert. Their numbers have increased throughout the region by more than 1,000 percent over the past 30 years.\n\nI couldn't find a link with the population but quite a bit of info. I hope this is helpful. Thanks for the recipe.

Adverse climate changes has caused the area to undergo a rapid desertification whereby in the past the area was one of the most fertile lands supporting ancient civilizations. Now it is mostly barren and intensive cultivation and deforestation has caused infertile conditions and rapid creeping of deserts into fertile lands. Thus very little life can be supported there and drought conditions is evident most of the year, only very hardy desert animals and plants can withstand conditions there. The area is also one of the least populated areas in the world.

Well they dont hibernate or go into torpor like ground squirrels or bears do. They have peiods, sometimes lasting several days with reduced activity, but they will emerge on the warmer days and forage for food. They remain opportunistic during the wionter months as well, if the oportunity for food presents itself, they happily respond!

the egytian desert provides extremely  hot environment . this prevents decay of dead bodies and the process of  mummification is thereby supplemented by it. since the the tombs were relatively cooler than the prevailing conditions in the open they were first dried using salt with the added advantage of the climate then wrapped in linen.then these bodies were buried in tombs built exclusively for the rich and aristocratic.

Deserts cover about one fifth of the Earth’s surface and occur where rainfall is less than 50 cm/year. Although most deserts, such as the Sahara of North Africa and the deserts of the southwestern U.S., Mexico, and Australia, occur at low latitudes, another kind of desert, cold deserts, occur in the basin and range area of Utah and Nevada and in parts of western Asia. Most deserts have a considerable amount of specialized vegetation, as well as specialized vertebrate and invertebrate animals. Soils often have abundant nutrients because they need only water to become very productive and have little or no organic matter. Disturbances are common in the form of occasional fires or cold weather, and sudden, infrequent, but intense rains that cause flooding.\n\nThere are relatively few large mammals in deserts because most are not capable of storing sufficient water and withstanding the heat. Deserts often provide little shelter from the sun for large animals. The dominant animals of warm deserts are nonmammalian vertebrates, such as reptiles. Mammals are usually small, like the kangaroo mice of North American deserts.\n\nDesert biomes can be classified according to several characteristics.\nThere are four major types of deserts:\n\n\nHot and Dry\nSemiarid\nCoastal\nCold \n\nHot and Dry Desert\nThe four major North American deserts of this type are the Chihuahuan, Sonoran, Mojave and Great Basin. Others outside the U.S. include the Southern Asian realm, Neotropical (South and Central America), Ethiopian (Africa) and Australian.\nThe seasons are generally warm throughout the year and very hot in the summer. The winters usually bring little rainfall. Temperatures exhibit daily extremes because the atmosphere contains little humidity to block the Sun’s rays. Desert surfaces receive a little more than twice the solar radiation received by humid regions and lose almost twice as much heat at night. Many mean annual temperatures range from 20-25° C. The extreme maximum ranges from 43.5-49° C. Minimum temperatures sometimes drop to -18° C.\n\nRainfall is usually very low and/or concentrated in short bursts between long rainless periods. Evaporation rates regularly exceed rainfall rates. Sometimes rain starts falling and evaporates before reaching the ground. Rainfall is lowest on the Atacama Desert of Chile, where it averages less than 1.5 cm. Some years are even rainless. Inland Sahara also receives less than 1.5 cm a year. Rainfall in American deserts is higher—almost 28 cm a year.\n\nSoils are course-textured, shallow, rocky or gravely with good drainage and have no subsurface water. They are coarse because there is less chemical weathering. The finer dust and sand particles are blown elsewhere, leaving heavier pieces behind.\n\nCanopy in most deserts is very rare. Plants are mainly ground-hugging shrubs and short woody trees. Leaves are “replete” (fully supported with nutrients) with water-conserving characteristics. They tend to be small, thick and covered with a thick cuticle (outer layer). In the cacti, the leaves are much-reduced (to spines) and photosynthetic activity is restricted to the stems. Some plants open their stomata (microscopic openings in the epidermis of leaves that allow for gas exchange) only at night when evaporation rates are lowest. These plants include: yuccas, ocotillo, turpentine bush, prickly pears, false mesquite, sotol, ephedras, agaves and brittlebush.\n\nThe animals include small nocturnal (active at night) carnivores. The dominant animals are burrowers and kangaroo rats. There are also insects, arachnids, reptiles and birds. The animals stay inactive in protected hideaways during the hot day and come out to forage at dusk, dawn or at night, when the desert is cooler.\n\n\nSemiarid Desert\nThe major deserts of this type include the sagebrush of Utah, Montana and Great Basin. They also include the Nearctic realm (North America, Newfoundland, Greenland, Russia, Europe and northern Asia).\nThe su

Bears are thought to hibernate or sleep for 5 months to 7 months each year. In very cold climates bears may hibernate longer than in moderate climates, because the food supply in frozen climates is under snow cover longer. \n\nBears in captivity DO NOT hibernate at all because there is a ready food supply. Most bears do not eat, defecate or urinate during hibernation. This is accomplished through their metabolic systems. The bears appear to maintain the water content of their blood. The breakdown of fat reserves balance water losses. A small amount of urea is formed and is degraded and recycled into non-toxic elements. Much is yet to be known about this metabolic cycle. Grizzlies hibernate in dens. Some grizzlies utilize natural caves for dens, while others build dens in the sides of mountains, under hollow trees or other forested locations.

Tropical "The tropical desert is an environment of extremes: it is the driest and hottest place on earth. Rainfall is sporadic and in some years no measurable precipitation falls at all. The terribly dry conditions of the deserts is due to the year-round influence of subtropical high pressure and continentality"\n(see resource below)\n\nwhat we will call subtropical desert is fairly warm, with average annual temperatures above 10° C and precipitation up to 100 cm/year.  The temperate desert is less well-defined, but again precipitation is less (usually much less) than 100 cm/year and average annual temperature is less than 10° C. (see second link below)\n\nHope that helps! Good luck!!

They huddle under the leaves of shrubs, vines, and trees. Grassland birds nest within thick grasses. Many places, though, provide no shelter. Consequently, birds have evolved rain-shedding feathers. \n\nThey stay relatively warm and dry under their feathers. Still birds get wet. ...most birds don't seem to mind. If they can't find a place to hide, they'll simply stand in the rain. After the rain--and during--they fluff up their feathers to warm up and help themselves dry off."\n\nAfter a dry spell, even with shrubs and trees galore, they sit sometimes out in the rain and take showers.

Cacti have evolved into what we know them as today from living in arid conditions.\nSome cacti do still have leaves, these would be classified as more primitive on the evolution chain.\nTheir importance could be looked at in several ways, they can live where other vegetation cannot and they do provide food for many desert inhabitants.  Not in the sense that the cacti are consumed, but their flowers, fruit and seed pods are eaten by a wide variety of fauna.\nThe vegetarian animals that survive on such cacti in turn provide food for the many carnivores that live in the desert, coyotes, jaguars, rattlesnakes etc, all depend on the animals that live off of cacti.

Technically they do have soil. Just different kinds.\n\nSoil type is based mostly on texture & composition.\n\nSome deserts have loose sandy soil. Others have desert "pavement" which is essentially hard compacted soil.\n\nThere are 3 major types of soils under which all other subsoils fall. Pedocals are those soils found in the desert & other arid places. It is high in calcite b/c of lack of water filtering through the soil.\n\nThe other two are laterite which is found in humid tropical places that is high in iron oxide & pedalfers which are found in temperate climates. Like I said there are more but these are the main three types.
