Description:

Species diversity is the number of different species that are represented in a given community (a dataset). The effective number of species refers to the number of equally abundant species needed to obtain the same mean proportional species abundance as that observed in the dataset of interest (where all species may not be equally abundant). Meanings of species diversity may include species richness, taxonomic or phylogenetic diversity, and/or species evenness. Species richness is a simple count of species. Taxonomic or phylogenetic diversity is the genetic relationship between different groups of species. Species evenness quantifies how equal the abundances of the species are.

Most people recognize biodiversity by species a group of individual living organisms that can interbreed. Examples of species include blue whales, white-tailed deer, white pine trees, sunflowers, and microscopic bacteria that can't even be seen by the naked eye.

In a healthy ecosystem, diverse and balanced number of species exist to maintain the balance of an ecosystem. In an ecosystem, all the species depend on each other directly or indirectly. So to make a more efficient, productive and sustainable ecosystem, it is important to maintain high species diversity.

Biodiversity is important to humans for many reasons. Ecological life support  biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services.

Over-exploitation, pollution and habitat conversion are the main threats to species diversity. They cause a gradual loss of species on local, regional and global levels. Additionally, the introduction of species into new ecosystems destroys natural balance.

The problems with low biodiversity are many. Firstly, low biodiversity means that the trophic system is likely less functional. The places where there is low biodiversity (such as open oceans, deserts, and tundra) tend to be very vulnerable to disturbances.

Journal of Ecosystem and Ecography is an international open access journal publishing the quality peer-reviewed research articles relevant to the field of Environmental Sciences. The journal selects the articles to be published with a single bind, peer review system, following the practices of good scholarly journals. It supports the open access policy of making scientific research accessible to one and all.
