Biodiversity “Biodiversity” is often defined as the variety of all forms of life, from genes to species, through to the broad scale of ecosystems (for a list of variants on this simple definition see Gaston 1996). “Biodiversity” was coined as a contraction of “biological diversity” in 1985, but the new term arguably has taken on a meaning and import all its own. A symposium in 1986, and the follow-up book BioDiversity (Wilson 1988), edited by biologist E. O. Wilson, heralded the popularity of this concept.

Biodiversity Maintaining multiple ecosystem processes at multiple places and times requires higher levels of biodiversity than does a single process at a single place and time. It plays a part in regulating the chemistry of our atmosphere and water supply. Biodiversity is directly involved in water purification, recycling nutrients and providing fertile soils.

- Biodiversity is More than Just Species. Species diversity is only one part of biodiversity. To properly catalogue all the life on Earth, we also have to recognize the genetic diversity that exists within species as well as the diversity of entire habitats and ecosystems.Genetic Biodiversity is the variation in genes that exists within a species.ll dogs are part of the same species, but their genes can dictate whether they are Chihuahua or a Great Dane. There can be a lot of variation in genes – just think about all the colors, sizes, and shapes that make up the genetic diversity of dogs.

What is biodiversity? Megadiversity describes countries with very high levels of biodiversity. Twelve of the megadiverse countries, including Australia, contain about 75% of Earth's total biodiversity. As a 'developed' nation, Australia has a special responsibility for biodiversity conservation and management.

Biodiversity Biodiversity underlies everything from food production to medical research. Humans use at least 40,000 species of plants and animals on a daily basis. Many people around the world still depend on wild species for some or all of their food, shelter and clothing.

CONTENTS The number and variety of plants, animals and other organisms that exist is known as biodiversity. It is an essential component of nature and it ensures the survival of human species by providing food, fuel, shelter, medicines and other resources to mankind.The richness of biodiversity depends on the climatic conditions and area of the region.iodiversity is the variety of different types of life found on Earth and the variations within species.

- A third definition of biodiversity is based on genetic diversity. Genetic diversity refers. either to the number of alleles in a given population or to the number of rare alleles present in the. population. Yet another way to conceptualize biodiversity is to think of it as evenness. Evenness can be. applied at multiple levels of analysis (biomes, species, or alleles).

Biodiversity in the Grassland Biome Biological diversity (biodiversity) refers to a broad spectrum of types and levels of biological variation. One of the ways scientists quantify Earth’s terrestrial biodiversity is by classifying vegetation into large, regional ecological units by dominant vegetative pattern, better known as biomes.he grassland biome covers about one-quarter of the Earth’s land surface and in North America grasslands account for about 15 percent of the continent.

Biodiversity & Human Well-being Biodiversity is a contraction of biological diversity. It reflects the number, variety and variability of living organisms and how these change from one location to another and over time. Biodiversity includes diversity within species (genetic diversity), between species (species diversity), and between ecosystems (ecosystem diversity).

Biodiversity How does biological diversity relate to the characteristics of the abiotic factors of an ecosystem? The availability of abiotic factors such as light, moisture, mineral salts, heat and carbon dioxide, more or less conditions the biodiversity of an ecosystem. Photosynthesis depends on water and light, and plants also need mineral salts, carbon dioxide and adequate temperature for their cells to work.

- for biologists, biodiversity is the diversity of organisms and species, but also the way these organisms function. Organisms appear and disappear; sites are colonized by organisms of the same species or by another. Organisms and species do not use the same strategies of reproduction, depending on their environment.

What is Biodiversity? - Definition and Relation to Ecosystem Stability Types of Biodiversity. Biodiversity is a very broad term and is often divided into three types. The first type of biodiversity is species diversity, and this is the type of biodiversity most people are familiar with.Species diversity is defined as the number and abundance of different species that occupy a location.n example of ecological diversity on a global scale would be the variation in ecosystems, such as deserts, forests, grasslands, wetlands and oceans. Ecological diversity is the largest scale of biodiversity, and within each ecosystem, there is a great deal of both species and genetic diversity.
