South American Savanna
Transcript of South American Savanna
This map shows where the Southern American Savanna is located in South America. Surprisingly it is not the largest biome in South America. As you can see the Savanna is located in a small part of the Northern area and in the East. The savanna biome is not as common in South America as it is in Africa. In Africa you can see that the Savanna takes up most of Southern Africa and part of mid to western Africa as well.
This picture is a map of the entire Globe. It shows where every savanna biome is located on this Earth. As you can see the savanna biome does not exist in the northern part of the hemisphere. The savanna is only located in South America, Africa, India, Australia, and a small part of Southern Asia. The cause of this could be the climate. The climate in the northern hemisphere is probably too cold for the Savanna biome to thrive. The Savanna probably needs a warmer and dryer climate.
This picture shows the beauty and the landscape of the South American Savanna. There are few trees in the biome. As you can see the trees are all scattered. This is because there is not enough rain fall on savanna to support forests. The size of the Savanna is huge. In Brazil, Colombia, and Venezuela, savannas occupy some 2.5 million square kilometers, an area about one-quarter the size of Canada. This just goes to show how big this biome can get.
This picture shows the type of trees that are located in the Savanna. These trees do not grow right next to each other. There is few rain fall so there aren't many plants. The Savanna is dry so the plants and trees have to adapt to the weather.
The plants and trees have a unique adaption for survival in this biome. Plants of the savannas are highly specialized to grow in this environment of long periods of drought. They have long roots that can reach deep underground for water. The trunks and leaves can store and conserve water during the dry season.
This is a Jackalberry Tree. It is most commonly found on savannas or savanna woodlands where it can be found growing on termite mounds. The termite mounds provide the tree with aerated soil, and a source of moisture. The roots provide protection for the termites as well. This tree grows better in moist soil. It is commonly found near riverbeds and swampy areas.
This is an Umbrella Thorn tree. The bark has a rough feel and is grey to black in color. The tree reaches heights of between 5-20 m in nature. Many bird species take advantage of this protection and build their nests in the canopy. This tree is a drought resistant species, the umbrella thorn grows in areas with annual rainfall as low as 40 mm and as much as 1200 mm, with dry seasons of 1-12 months.
This is the Four Eyed Frog. It looks much like any typical frog when viewed from the front. However, when viewed from behind, this little amphibian looks far from ordinary. It seems like it has a second set of eyes. This second “face” might fool predators into thinking that it is bigger than he appears—perhaps too big to tackle.
This is a Rhea. It is a large, flightless bird. It is the largest bird in the Americas. The common rhea is a fast runner; when it runs, its neck is almost horizontal to the ground. Rheas congregate in flocks of about 20 to 30 birds. The Rhea can grow up to 5ft.
This is a maned wolf. The maned wolf stands about three feet tall at the shoulder and weighs about 50 pounds. It looks like a long-legged fox, with a reddish-brown coat and a mane along its back. Its ears are large and long and can range up to 7 inches. The maned wolf inhabits open forest, savanna, and marshland. Maned wolves are omnivorous, eating small mammals, insects, reptiles, birds, bird eggs, fruits, and vegetation.
This is a Capybara. It is a semi-aquatic rodent of South America. It weighs about a hundred pounds, and is about 2 feet tall at the shoulder. This animal is an herbivore. It eats food like corn, plants, etc. It has a lifespan of about 4 years in the wild.
This a Guanaco. It is described by Charles Darwin as “an elegant animal, with a long, slender neck and fine legs.” The Guanaco is the largest wild member of the camelid family in South America. It is also believed to be the ancestor of the domestic llama. Like other camelids, the guanaco walks on enlarged sole pads, with only the tips of the hooves touching the ground; in the guanaco these pads are moveable and help give grip on rocky and gravelly terrain.
This animal is called a Jaguarundi. This cat is unique in its appearance among the felids in that it more closely resembles a weasel. Adults can weigh as little as 6 pounds or as much as 20. They stand 10-14 inches at the shoulder, and reach a length of 35-55 inches. Jaguarundis are the most adaptable in its ability to occupy diverse environments. They are Carnivores. Their primary diet is quite varied and is comprised of small rodents, rabbits, armadillos, opossums, quail, wild turkey, reptiles, frogs, fish and domestic poultry. Their lifespan is around 15 years.
This is the trophic level of the Savanna. This show the relationship between the plants and animals in this biome. Carnivores (lions, hyenas, leopards) feed on herbivores (impalas, warthogs, cattle) that consume producers (grasses, plant matter). Scavengers (hyenas, vultures) and decomposers/detritivores (bacteria, fungi, termites) break down organic matter, making it available to producers and completing the food cycle (web).
This is a graph that shows the range of temperature in thte South American Savanna. This biome gets the hottest from September- March. However, it's the coldest in June and July. This graph also shows that wild fires occur during the months of September - March.
Large fires sweep across much of the landscape every year. The grasses that cover the ground in these areas can grow as high as 3 metres as they get plenty of sunshine and plenty of rain in the wet season – usually over 800mm. Then they dry out rapidly, and can carry fire throughout the dry season from shortly after the last rains. They reach their most flammable state when the next wet season is about to begin.
In the savanna climate there is a distinct dry season, which is in the winter. During the distinct dry season of a savanna, most of the plants shrivel up and die. Some rivers and streams dry up. Most of the animals migrate to find food. It is usually cooler during the dry season by a few degrees. Because it is in the tropical latitudes that is still hot enough. In the winter, it is usually about 68° to 78° F (20° - 25° C).
The Savanna gets all of its rain in the summer months. In the wet season all of the plants are lush and the rivers flow freely. The animals migrate back to graze. In the summer the temperature ranges from 78° to 86° F (25° - 30° C). There is an annual precipitation of 10 to 30 inches (100 to 150 cm) of rain. From December to February hardly any rain falls at all.
This plant is a Curcuma. The Curcuma can range in height from just under 2' to over 7' tall. This plant has been cultivated for more than 4000 years. The Curcuma has been used for food, spices, and medicine. It can be used for lowering blood pressure, slowing down Alzheimer's disease, and relieving pain.
This plant is known as the Savanna Blazing Star. The flower heads open from top to bottom, as is typical for the genus Liatris. On this species, the uppermost flower head is usually the largest. When the central spike is finished blooming, side branches may develop and send up additional flowering spikes. Seeds are present from October into the winter months. Savanna blazing star grows from an underground corm, which increases in diameter as it ages.
