The Tropical Savanna has a climate that is wet and dry, it has a unique vegetation and has lots of organisms living there. The tropical Savanna has an average temperature at 64 o and precipitation averages at 30 to 50 inches. The tropical Savanna has a dry season for at least five months of the year. Because of the conditions in the tropical Savanna, organisms like the North African ostrich and African baobab tree must be well adapted to survive in their natural habitat. The North African ostrich has a scientific name of Struthio camelus and lives at the tropical Savanna. The ostrich is a vertebrate in the phylum class chordata. Also the ostrich eats roots, leaves, seeds, insects, snakes, lizards, and rodents. In addition, ostriches can survive
The species can accept annual precipitation ranges between 40 inches and 60 inches, and annual temperature averages between 48 degrees and 70 degrees Fahrenheit.
Elijah Anderson wrote an interesting book, The Cosmopolitan Canopy: Race and Civility in Everyday Life, which describes social settings and people interactions in different parts of Philadelphia’s neighborhoods. This book was published on March 28, 2011 by W. W. Norton & Company. Anderson has observed these places in Philadelphia for over thirty years. He uses the observations he made and the stories that people shared with him during his endeavor to answer the following questions: “How do ordinary people in this diverse city interact across and along racial lines? When and how do racial identities figure out into these encounters? When and how do city dwellers set aside their own and other’s particular racial and ethnic identities to communicate
Sandikhola has a subtropical climate and receives on average 1400-2000mm of rain per year and has an average of 26oC. Sandikhola has a two-season year made up of the dry and wet seasons. The dry season runs from October to May and the wet season from June to September.

Due to the moderating effect, this ecozone has long, mild summers (18 to 22°C) and cool, short winters (-3 to -12°C), with around 720 to 1000mm of precipitation, and 180 to 260 growing days annually. The Westerlies can also alter the weather quickly in this ecozone.
The climate of Missouri and the temperate deciduous forest is similar in terms of precipitation and temperature. The average annual temperature in Missouri is 45-66 degrees Fahrenheit ("Average Annual Temperatures in Missouri"). This data makes Missouri fall into the deciduous forest biome because the broad temperature range for this biome is -22-86 degrees Fahrenheit (Przyborski). Missouri receives an average of 44.2 inches of rain and snow every year ("Average Annual Precipitation for Missouri"). The precipitation range of the temperate deciduous forest biome is 29-59 inches of rain and snow every year (Przyborski). This fact furthers the proof that Missouri is a state with the temperate deciduous biome. The terrain of both regions is also extremely similar.
Humans have almost nothing in common with any surviving mammals of the savanna. Most mammals of hot, dry climates do not rely heavily on water for survival. They have a high tolerance to heat, and their body temperatures can fluctuate more than 6oC between day and night. They can bear a dehydration of 20%, whereas 10% or more would be fatal to humans. What little they do drink or consume naturally through food, is conserved because they do not sweat. Hair and fur keeps the sun off their direct skin, while humans would have to sweat 10-15 liters of water to physically cool down. (Verhaegen)
Tropical rainforests are an extremely unique and diverse ecosystem that are located around the earth’s equator. They once covered roughly 7% of the world, but due to human encroachment that has dwindled to just 2%. It is a highly moisture rich environment that typically receives anywhere between 60 and 400 inches of rainfall annually and average humidity ranges from 70 to 90%.
How does the vegetation surface type affect the amount of runoff? Speculate why this happens.
Morocco's climate is Mediterranean with more extreme weather in the interior region (Central Intelligence Agency, 2013). There are year-round hot conditions in the south and east (Piazza, 2007). The rainy season is from about October to May, and the dry season, from May to October (Perkins, 2010).
The highlands here can receive up to 80 inches of rainfall a year and average temperatures in the low 60s F (Brittanica.com). Attoh classifies the remaining areas as the B (dry climate) subcategory of Bsh (semiarid climate).... ... middle of paper ... ...
Differences Between the Emu, Rhea, and Ostrich Emu, Rhea, Ostrich… these are the names of three of the five flightless birds in the ratite family. These three birds all look strikingly similar except for their size, but is that really the only difference? Although their size is an extreme factor in their life they have several other differences. The three main differences between the emu, rhea, and ostrich are their habitat, their predators and defense, and how they raise their young. Before going more in depth about each of these differences let’s take a look at a brief background of these three birds.
Savannas are subject to regular wildfires and the ecosystem appears to be the result of human use of fire. For example, Native Americans created the Pre-Columbian savannas of North America by periodically burning where fire-resistant plants were the dominant species. Pine barrens in scattered locations from New Jersey to coastal New England are remnants of these savannas. Aboriginal burning appears to have been responsible for the widespread occurrence of savanna in tropical Australia and New Guinea, and savannas in India are a result of human fire use. The maquis shrub savannas of the Mediterranean region were likewise created and maintained by anthropogenic fire.
Between the months of December and February there will be no rainfall at all. The dry seasons will only have an average around 4 inches of rainfall. The Savannas climate temperature has a range of 68°F to 86° F. During the winter the Savannas temperature is usually around 68°F to 78° F which is about 20°C - 25° C. In the summer the Savannas temperature ranges around 78°F to 86° F which is around 25°C - 30°C.
In order to carry out a study on the diversity of a savanna biome we needed first to have an understanding on what makes up a savanna and the distribution, both world wide and locally, of such a biome. The definition of a savanna according to Collins (2001) is an area that “is characterized by a grassy ground layer and a distinct upper layer of woody plants. Where this upper layer is near the ground the vegetation may be referred to as Shrubveld, where it is dense as Woodland, and the intermediate stages are locally known as Bushveld.” Looking world wide at areas that fit such a description one can pick out a pattern of where they occur, namely along a broad band on either side of the equator where temperatures are warmer and seasonal rains occur. Savanna biomes are thus found on three continents, which include Australia, Africa and Central and South America (Biodiversity Savanna, Global Environment web site). To understand what makes a South African savanna different to the others we need to investigate the differences between them.
