1. Ecotone, Edge Effect, Ecological Niche and Equivalents(Environmental Science and Technology) Total View (368)
 
An ecotone is a biologically rich area with very high species diversity. In some cases.the number of species and the population density of some of the species are greater in the ecotones than in the adjacent ecosystems.

2. Habitat, Ecological Niche, Biosphere, Biodiversity(Geography) Total View (225)
 
A habitat is where things live. It 's more than a home; it's more like a neighborhood. For an animal a habitat includes all the land the animal needs to hunt, gather food, find a mate, and raise a family. Different combinations of ecosystem LAWS (light, air, water and soil), together with variations in climate and topography, create different habitats. A shady area supports different species of tr ......

3. Ecology-Concept, Structure and Functions of Ecosystem(Indian Constitution, Human Rights and Environmental Studies) Total View (228)
 
The term Ecology was coined in 1866 by the German biologist Ernst Haeckel from the Greek oikos meaning "household" and logos meaning "science:" the "study of the household of nature." It was initially meant for animal only and was defined as investigations of the total relations of the animal to its organic and inorganic environment.

Density represents the numerical strength of a species in the community in any unit area. Frequency does not provide correct idea of the distribution of any species in particular area, unless it is correlated with other characters, like density etc . The inherent tendency of all animal populations is to increase in number. But this increase in number is, however, not infinite since the carrying ca ......

Biomes are the earth's largest storehouse of biodiversity. Many of these species have developed over the time in highly specialized niches and that makes them more vulnerable to extinction when their natural home or niche is destroyed . About 50 to 80% of global biodiversity lies in these rain forests. More than one-fourth of the world's prescription drugs are extracted from plants growing in trop ......

The tendency of an ecosystem to return to a state of equilibrium is referred to as homeostasis. Ecosystems have a unique property of self-regulation.The ecosystem comprising various sub-components of biotic and abiotic nature, which are inter-linked and interdependent,have an inherent property to resist change. That means, the ecosystems have a property to tolerate external disturbance or stress. ......
