Biodiversity: Types, Importance and Conservation Methods (with diagram)

Because of these characteristics, biodiversity plays a fundamental role in maintaining the aesthetic value of the environment, the integrity of the natural environment, and promotes the overall well-being of all plant and animal life. This calls for the need for biodiversity conservation for the survival of all living things and their natural habitat. We should preserve every scrap of biodiversity as priceless while we learn to use it and come to understand what it means to humanity. A single species of organisms with diverse genetic diversity portray more adaptability and survival mechanism against adverse environmental conditions compared to organisms of a single species with the same genetic make-up. Species diversity refers to the variety of organisms in the environment.

Biodiversity

The term biodiversity was coined as a contraction of biological diversity by E. Wilson in Biodiversity may be defined as the variety and variability of living organisms and the ecological complexes in which they exist. In other words, biodiversity is the occurrence of different types of ecosystems, different species of organisms with the whole range of their variants and genes adapted to different climates, environments along with their interactions and processes. Biodiversity includes the genetic variability for which different varieties of spices have appeared in the course of evolution and diversity of life forms such as plants, animal microbes, etc. The diversity may be interspecific within species and interspecific in between the species but these are well supported by ecosystem.

Founded in , Biodiversity and Conservation is an international journal that publishes articles on all aspects of biological diversity, its conservation, and sustainable use. It is multidisciplinary and covers living organisms of all kinds in any habitat, focusing on studies using novel or little-used approaches, and ones from less studied biodiversity rich regions or habitats. It also features rapid assessment approaches, the estimation of species numbers and diversity by traditional, molecular, or proxy indicator methods , habitat management, conservation policy and regulations, threats, biodiversity loss, extinctions, and the documenting of long-term changes, and ex-situ conservation. It includes reviews, research papers, editorials, commentaries, and letters, and sometimes whole issues devote to particular topics.

The number and variety of organisms found within a specified geographic region. The variability among living organisms on the earth, including the variability within and between species and within and between ecosystems. Biological diversity — or biodiversity — is the term given to the variety of life on Earth. It is the variety within and between all species of plants, animals and micro-organisms and the ecosystems within which they live and interact.

Biodiversity is the biological variety and variability of life on Earth. Biodiversity is typically a measure of variation at the genetic , species , and ecosystem level. Rapid environmental changes typically cause mass extinctions. The age of the Earth is about 4. There are microbial mat fossils found in 3.

Conserving biodiversity outside the areas where they naturally occur is known as ex situ conservation. Here, animals and plants are reared or cultivated in areas like zoological or botanical parks. Reintroduction of an animal or plant into the habitat from where it has become extinct is another form of ex situ conservation. For example, the Gangetic gharial has been reintroduced in the rivers of Uttar Pradesh , Madhya Pradesh and Rajasthan where it had become extinct. Seedbanks, botanical, horticultural and recreational gardens are important centres for ex situ conservation.
