The Savanna Biome
The planet is divided into major climatic regions referred to as biomes, these regions differ in climate, sunlight received and these regions have different weather patterns. Each biome has a set of plants and animals that can survive in its climate. Savannas are part of the world’s major Earth biomes; they are made of between 10% and 15% of the world’s land surface (Sankaran et al., 2005). Savannas occur in the tropics where there is inadequate rainfall throughout the year, if there was enough rainfall this region could end up being a rainforest. The Savanna has two seasons, the rainy season and the dry season. There are two types of grasslands, the Temperate Grasslands and the Tropical Grasslands which are also known as

The Koppen Climate classification is a system that can be used to classify world climates. The Koppen Climate Classification has been established with regards to the empirical relationship between climate and vegetation (Chen D and Chen H, 2013). Savannas experience warm temperatures .Climatic Savannas result due to climatic conditions, Edaphic Savannas result from soil conditions which are not maintained by fire and the Derived Savanna is due to a result of deforestation (Oudtshoorn et al. 2011). The Savanna vegetation is a mixture of trees, grasses, shrubs and the vegetation also includes ground plants but the proportions can change according to a certain area and over a certain period of time. Savanna characteristics include the grass found in the savanna, savanna woodlands, savanna fires or annual fires due to the dry seasons. Savannas mostly have soils that are poor in nutrients and Savannas also have topographic variations, with the lower slopes being nutrient rich compared to the upper and middle slopes. The upper land Savannas usually experience high rainfall and experience better drainage. The grasslands are influenced strongly by the herbivores and fires (Bond & Keeley, …show more content…

Depending on the biomes, rainfall and soil can vary. However, the rainfall is typically ranges from 30 cm to 200 cm. In mountainous regions and forest biomes, there would be plenty of rainfall. While in the grasslands, there’s little rainfall. In the temperate zone, there are two main types of trees, coniferous and deciduous. The deciduous trees, in the South, drop their leaves in the winter. Generally, the trees are usually small in height unless in the forest areas. The forests tend to have wide leaves and tall, large trees. The soil in deciduous forests is found to be very fertile. The different amount of rainfall in the forest areas and the grasslands cause the difference between the trees and plant height. The rainfall in forest regions can lead them to be very common with the rainforests. Furthermore, the changes and variation of weather could be the reason as to why the forests shed or don’t shed their leaves. The leaves show a correlation between the fair amount of sunlight during the summer causing the leaves
What is a biome? Biomes are major life zones characterized by vegetation type or by the physical environment. Climate plays a role in determining the nature and location of Earth’s biomes. Texas has 10 different ecosystems with lots of diversity. Minnesota has 4 different ecosystems which are also quite diverse. Regardless of the size of the biomes or the number of biomes in each state, they are all important not just to the locate environment but on a global level because of the life they support. We are going to take a look at the different biomes, comparing climate and rainfall, as well as vegetation fauna.
The Taiga Biome is also known as the boreal forest. The taiga biome is the largest terrestrial biome and extends across Europe, North America, and Asia. The taiga is located near the tundra biome. It has short wet summers and l0ng cold winters. The taiga get a large amount of snow during the winter and plenty rain during the summer. The taiga is found throughout the high northern areas. The taiga makes up 29% of the world’s forest’s the largest areas are located in Canada and Russia. It has the lowest temperatures in winter. Temperatures vary from −54 °C to 30 °C throughout the whole year. Taiga soils tend to be poor in nutrients. It doesn’t have the deep, enriched nutrients present in temperate deciduous forests. Due to the cold the soil is also very thin which messes up the development of soil and the ease with which plants can use its nutrients.
Another biome in the park is their temperate forest. Temperate forests have high humidity, high levels of precipitation, and variety of trees are also included. Freshwater biomes surround the park as well.
The Taiga Biome is a large, naturally occurring community of flora and fauna occupying a major part of both Siberia and North America. It is usually found at high elevations at more temperate latitudes in the Northern Hemisphere. It is the largest terrestrial biome on earth, covering around 50 million acres of land (NP, UC Santa Barbara). It is known for its subarctic climate that ranges between -51 to -1 °C in the winter and -21 to 7 °C in the summer. The two main season found in the taiga are summer and winter as autumn and spring are usually very short and barely noticeable. Winter makes up around six months of the year, with only around 50-100 frost-free days during the summer. Summer is also the season during which the taiga receives the most precipitation in form of rain. The remainder is made up of snow and dew, which adds up to around 30-85cm of precipitation yearly (NP, S.L. Woodward).

Temperate grassland biomes can be found in North America, Africa, the pampas of South America and many parts of Eurasia. Grass is the main plant in Temperate Grassland biomes, trees and shrubs are rare to see in this type of biome. Temperate grasslands also have an extremely high abundance of wildlife. The wildlife living in this biome includes bison and pronghorn sheep, but mainly the animals most affected were the cattle and horses that lived on the surrounding farms.
The following paper will explore two different biomes: Boreal Forest and the Tropical Rainforest. An examination of these two biomes will provide an understanding of how these biomes exists and the various types and forms of processes that acted on it and are acting on it both biologically and through abiotic factors.
The maps demonstrate the quantity of considered species now exhibit in the Wet Tropics bioregion under the present atmosphere and those normal with temperature ascents of 1°C, 3.5°C and 5°C appeared by shading code at the left. The effects of changes in precipitation are excluded in this illustration. Adjusted from Williams et al. (2003).
In the Savanna during the wet season, all of the plants are growing freely and at an enormous rate. It rains often during the wet season so the lakes and streams are flowing. The animals that migrated away during the dry season all return back to
One of the most predominate ecosystems is the forest community. Covering about one-fourth of the land area on Earth, forests consist mainly of trees and other woody vegetation, growing closely together. The trees can be large and densely packed, as they are in the coastal forests of the Pacific Northwest, or they can be relatively small and sparsely scattered, as they are in the dry tropical forests of sub-Saharan Africa. Forests are complex ecosystems that also include “soils and decaying organic matter, fungi and bacteria, herbs and shrubs, vines and lichens, ferns and mosses, insects and spiders, reptiles and amphibians, birds and mammals, and many other organisms” (Audesirk, 2003). All of these components constitute an intricate web with many biological interconnections. A bird may depend on the upper branches of a tree for nesting, while the tree may depend on the fungi surrounding its roots to obtain water and nutrients. A forest performs a number of vital environmental services, such as cleansing the air, moderating the climate, filtering water, cycling nutrients, providing a habitat for animals and provides humans with recreation and beautiful scenery. Resources from the forest supply raw materials, such as lumber, paper products, greenery and pharmaceuticals. Some of the developing issues today concerning forests are fires and what we as a society can do to restore the natural ecosystems within the forests around our world. Many aspects are to be considered when looking at the ecology and bioremediation of forests such as, human activities, wildlife, endangerment and environmental changes. This paper will discuss the effect wildfires have on the forest ecosystem.
Thesis: Forests provide the earth with a regulated climate, strong biodiversity, and good nutrient rich soil for plants to strive on.
A biome, also known as life zones, consists of all plants, animals, and other organisms, as well the physical environment in a particular area. A biome is characterized by its’ plant life, climate, and location. The climate and physical features determine the boundaries of a biome. A biome is made up of many different ecosystems. The ecosystems tend to have the same pants and animals as neighboring biomes around the boundaries. The major biomes are the tundra, taiga, tropical rain forest, temperate forests, desert, grassland, savanna, chaparral, and marine. Each biome has it’s own characteristics such as the tundra.
