GE6351 ENVIRONMENTAL SCIENCE AND ENGINEERING UNIT I ENVIRONMENT‚ ECOSYSTEMS AND BIODIVERSITY ENVIRONMENT DEFINITION: It is defined as the sum total of water‚ air‚ and the inter-relationship that exists among them and with the human beings‚ other living organisms and materials. SCOPE: As a subject it has a wide scope. It encompasses a large number of areas and aspects‚ which may be summarized as follows 1. Natural resources 2. Ecology and biodiversity 3. Environmental pollution and control 4. Social

This region is almost continuous open grassland‚ interrupted by more forested locales along the major river valleys and in those areas‚ such as the Black Hills of eastern Wyoming and western South Dakota‚ where the expanse of open plains was interrupted by isolated mountainous areas.

occur at once. They took place in phases. The Bantu speaking people were part of the Iron Age people from the Middle East. They settled along the banks of the River Nile. Later‚ they moved to North Africa and occupied some areas in the Sahara grasslands. From here‚ they moved to the area around Lake Chad‚ Nigeria and the Cameroon highlands area called the Benue-Cross region. However‚ some settled in the great lakes region in east Africa. These people were given the name ‘Bantu’ because of the

threatened by the loss of their habitat‚ constant degradation and fragmentation going on. These elephants are not only a cultural icon in India and throughout Asia‚ but they also help maintain the integrity of their forests and help preserve their grassland habitats. Many people have a hard time understanding the difference between the Asian elephant and the more commonly known African Elephant. The Asian elephant is substantially smaller in size‚ has a rounder head‚ and has a back that is more convexed

Ancient lineages across the Drakensberg Alpine Centre and their plight for conservation. 1. Introduction: With many recent studies showing that the current global rates of biodiversity loss are cause for alarm‚ it is important to recognize regions in which biodiversity is especially high and under threat from human expansion and climate change. The combinations of biodiversity assemblages along the Escarpment form nodes of high local endemism that have contributed towards the concept of ‘centers

Introduction Camouflage‚ in other words the ability to blend in with the surroundings is a profoundly studied feature in many animals. From empirical evidence‚ animals like Chameleon and the Leaf-Tailed Gecko which have pigments that match their surroundings are much harder to spot than animals whose pigments don’t. Recent studies have shown that the bark-resting moth has a tendency to live within a habitat that has a hue similar to itself. It can alter its position on the background for a better

tropical biome monopolized by grasses‚ shrubs‚ and small trees. It’s grassland cover western India‚ northern Australia‚ South America‚ and other parts in Africa. In this biome it is very warm‚ there is little precipitation so there is not a lot of tall trees more like shrubs and bushes. A savanna is categorized between a tropical rainforest and a desert biome it is right in the middle of them. Savannas are created when humans burn grasslands and cut down trees kind of like slash and burn process to plant

Explain TWO ways in which the modern horse is adapted to open grassland. (4) 1.1.4 Explain ONE way in which the hoof of the modern horse could be a disadvantage in the open grassland environment.

Conservation is the practice of protecting plants or animals‚ and their habitats. These plants and animals may be very close to extinction. North America experienced a big loss of megafauna at the end of the Pleistocene era (about 13 000 years ago). This started a program known as “Pleistocene re-wilding”. Re-wilding involves the reintroduction of extant species into areas where they became extinct in the past. This program aims to restore the evolutionary and ecological potential that North America
