“Animal life encyclopedia” written by Bernhard Grzimek’s, an author and a zoologist, states that there are two recognized varieties of African elephant – African Steppe (also known as Savanna) elephant, which belongs to Sudan region and is characterized by its big ears, four toes on the front, and three toe on the hind legs, and also Bush or Forest elephant, which has round years, five toes on front, and four toes on hind legs (p. 500). The measurements of the size and weight of this majestic animal, which is the largest to walk the earth, are impressive, “L [including trunk] 6-7.5 m, TL 1-3.3 m, shoulder height 3-4 m, weight 5000-7500 kg [making the African elephant the heaviest land mammals alive today]” (Grzimek, p. 500). And as for the …show more content…
The Savanna elephants “…throw their weight around in search for food. They prune savanna brush on a gigantic scale, tear down trees, and crash through thick woods to reach water holes. This creates habitats for smaller animals. They get new paths to trod, newly trampled land on which to graze” (Allen, p. 143). As for the Forest ones, “…elephant tree-tearing opens the land to the sky, creating glades for a host of animals.” (Allen, p. 143). Besides, elephants have a connection to the way the plant ecosystem develops: “Even in death elephant changes the environment, for as the great body decomposes, toxic fluids kill the roots of certain trees, producing another clearing” (Allen, p. 143). And this reflects the niche that African elephant has in its environment, being an essential part of the ecological and biological systems of Africa. But African elephants can play sometimes a negative role in the environment as well, “In some protected areas, such as Tsavo National Park (Kenya), elephants are crowding together in such large numbers that they are destroying the local flora, endangering other protected species there…” (Grzimek, p. 501).
African elephant is a mammal, it belongs to an African clade of the eutherians, or placental mammals - “…elephants are part of this African lineage, called the Afrotheria…” (Raven et al. p. 520). Its order Proboscidea gave the rise to the Elephantidae group to which African elephant belongs, along with the related Asian elephant species, which however differ from African species when it comes to anatomy and evolutionary line (Grzimek,

Sustainable Monitoring Systems

...Monitoring sustainability with a monitoring system that is itself sustainable: addressing the cause and the symptoms IAN WATSON,1 AND PAUL NOVELLY, 2 1 Department of Agriculture and Centre for Management of Arid Environments PO Box 483 Northam, Western Australia, 6401 Ph 08 9690 2000 Fax 08 9622 1902 iwatson@agric.wa.gov.au 2 Department of Agriculture and Tropical Savannas CRC Kununurra, Western Australia ABSTRACT Throughout the 1970s and 1980s much effort was expended on a range monitoring program in Western Australia. Unfortunately, much of the system put in place is now inactive. Such a situation is not unique and the rangelands of the world are littered with monitoring sites that are no longer part of an operating system. A need has emerged for a biodiversity monitoring system in the rangelands and the discussion is currently at the point where the range management discipline was in the early 1970s. Efficiencies can be made when developing the biodiversity monitoring system by learning from the experience of the range management profession. Monitoring sustainability will only be possible if the monitoring system is itself sustainable. We suggest a number of attributes for the system that need to be in place before the system can be judged at all sustainable. These attributes are a mix of biophysical, social and institutional and highlight the view that monitoring systems of the type being suggested constitute an unusual mixture of attributes not found in...

Grasslands

...There are two types of grasslands, tropical and temperate. Tropical grasslands are warm year around and have a dry and rainy season. Temperate grasslands have an average of 10 to 30 inches of rain per year, have shorter grass, and have a growing and dormant season (Grasslands Terrain of Many Names). There are the Great Plains in the United States that cover from parts of Texas, New Mexico, Oklahoma, Colorado, Wyoming and Montana and covers all of Kansas, Nebraska, South and North Dakota, and covers all the way up into parts of Canada. In Africa there is the African Savanna, which is a tropical grassland that covers 25 territories and South Africa. The abiotic structure of grasslands includes the climate; rainfall, temperature, wind flow, and ground moisture. The bedrock has an influence on the type of soil and what can and cannot be grown in that location, slopes and elevation, floods, fires, high temperatures and freezing temperatures are also abiotic structures. The biotic structures include any living thing in that ecosystem. Grass, rabbits, moles, elk, snakes, birds, bacteria and fungi are part of the biotic structures (tutorvista.com 2014). You cannot have one with out the other in an ecosystem. The grass needs the rain as well as the animals in order to survive. The temperatures help decide which type of animals and plant life will live in that area as well. Carbon function in the ecosystem is to be used by the plants for photosynthesis and to make organic molecules...

Ecosystem

...Forest ecosystem FOREST ECOSYSTEM A forest is more than just the trees. A single forest is a complete, functioning ecosystem that supports innumerable plant and animal species as well as earth, water, and air subsystems. The subsystems provide the essence of life of the forest and are in themselves a byproduct of forest systems, all of which are reciprocal and inter dependent. A forest ecosystem is a complex of living and non-living elements which interrelate. An ecosystem can be small (like your backyard) or large (like the planet earth). It depends on the range of individual species or group of species being discussed (e.g.: a salmon stock or a forest type), geology (e.g.: a mountain range or watershed), and other issues. Different organisms exist within the forest layers. These organisms interact with each other and their surrounds. Echo organism has a role or niche in sustaining the ecosystem. Some provide food for other organisms, other provide shelter or control populations trough predation. NEEDLE LEAF Needle leaf trees fall into two categories based on how they are attached to the twig coming off the branch of the tree. On coastal redwoods and true firs, the needles will be connected directly to the twig, growing off it like leaves off the branch of a common plant. On trees like spruce trees, the individual needles will be connected to the tree via a peg-like stalk, which is also known as a needle peg. Sometimes needles on conifers are bundled together...

Grassland Ecosystem

...Natural Resources and Energy Paper Robert Huitt, Rocharda Carter, Roxabel Perez Garcia, Salatethia Thomas, and Stephanie Lowe SCI 256 William Okrepkie April 13, 2015 Large open areas of grass or plants that are similar to grass are considered to be grasslands. The majority of time trees are not found in grasslands because grasslands tend to be too dry in an environment. Rainfall is the primary source of water, and the absorption occurs through the roots of the grass. The roots are extensive and yield multiple networks and modified photosynthesis. Multiplication of the grass occurs by pollen being excreted from wind or additional plants growing from the roots. During a period, grasslands accounted for over 42% of Earth. European settlers considered grasslands "prairies," which is French for "grassland." There are two main categories of grasslands which are Tropical Savannah and Temperate Grassland. These two are in areas that have hot summers and little rainfall. Africa, Australia, South America and Indonesia are where you can find Tropical Savannah Grasslands. Prairies or Steppes are other names used for Temperate Grassland. Grasslands are among the largest ecosystems in the world. Their area is estimated at fifty- two point five million. Square kilometers (Forages Information Systems, 2009). In actual practice, grassland agriculture includes the proper use of legumes as well as grasses. Grasses and legumes are used to feed livestock, support wildlife...

African Elephant

...The common name is the African Elephant, the scientific name is Loxodonta Africana, the phylum is Vertebrata, the class is Mammalia, the order is Proboscidea, and the family is Elephantidae. The Closest Relatives to the African Elephant are: the Asian Elephant, mammoths, primitive proboscidean (mastodons), sea cows, and hyraxes. Scientists believe that the African Elephant evolved from one of its closest relatives, the Sea Cow. The geographical location and range of the African elephant covers all of central and southern Africa. In Ethiopia there are isolated populations that exist around Lake Chad in Mali and Mauritania. Also in Kenya, Rhodesia, Tanzania, Zambia, Uganda, Zaire, and in National parks located in South Africa, as well as several other countries. African Elephants, originally, were found in all of the Sub-Saharan African habitats except desert steppes. Elephants still occupy diverse habitats such as: temperate grassland, tropical savanna and grass lands, temperate forest and rainforest, tropical rainforest, tropical scrub forest, and tropical deciduous forest despite their drastic decline in numbers. However, their migratory patterns and habitat use have changed, due to the fact that they are restricted to protected areas. The elephant can exist in many types of environments but it prefers places that have many trees and bushes, which the elephant needs both for food and shade. They also like warm areas that have plenty of rainfall. This ensures...

Invasive Species

Pick one species (endemic or invasive) and discuss its role in the environment. I choose an endemic species the Asian elephant. The elephants importance is that they assist with logging forests, carry heavy material, and assist as transportation. They have the ability to walk in areas where machines are unable to go, their vital role in an ecosystem is they modify the habitat that affects all other plants and animals. They provide water for other animals by digging water holes in the dry seasons (they can easily locate water underground). They make paths in the forest by pushing brush and pulling down trees and also disperse seeds of fruits by depositing them in their dung. 3. What economic impact does it have on human society? Endangerment affecting humans is due to the destruction of habitats there’s not enough food in the small forest for the elephants so they go and look for other food sources which are crops in nearby fields. Attempts were made to locate these animals but because of change in habitats they’ve raided villages and destroyed homes and crops not only do they pose a danger to human society we also pose a danger to...

...imbecile rapacity blew through it all, like a whiff from some corpse. By Jove! I’ve never seen anything so unreal in my life. And outside, the silent wilderness surrounding this cleared speck on the earth struck me as something great and invincible, like evil or truth, waiting patiently for the passing away of this fantastic invasion.”(page72) This quote offers Marlow’s first impression of the Central Station. The word “ivory” seems to be something he hears all too often now that he works for this company. To them, it is far more than just the tusk of an elephant or rhinoceros; it represents an economic freedom that companies have never seen or experienced. These companies are running amuck doing as they please with no thought of how their actions affect the people or animals of Africa they simply only care about “Ivory” and its economic value. Marlow’s reference to a decaying corpse is both literal and figurative: elephants and the African people both die as a result of the European’s pursuit for ivory and the entire enterprise of the ivory trade is just rotten at the core. This is true in the cruelties and the greed that are both part of a greater evil of how money corrupts the soul of every human, instead of thinking of each other you start to be selfish and be narcissistic to the core of your humanity. I see these companies creating an “African Holocaust” as Joseph Conrad says himself. This quote is why I see the book is titled as Heart Of Darkness, the Ivory trade is routed...
