What is variation in biodiversity?

Biological diversity, often shortened to biodiversity, is the variation of life at all levels of biological organization, referring not only to the sum total of life forms across an area, but also to the range of differences between those forms.

Why does biodiversity vary throughout the world?

The creatures that survive have fewer breeding partners, so genetic diversity declines. Pollution, overfishing, and overhunting have also caused a drop in biodiversity. Global climate change—the latest rise in the average temperature around the globe, linked to human activity—is also a factor.

What affects variation in biodiversity?

Genetic diversity influences biodiversity, and thus NCP, in two main ways: (1) through standing genetic variation (that is, the particular combination of genes and alleles present at a given time in a given place); and (2) through contemporary evolution (that is, ongoing evolutionary changes that affect the genetic …

Abstract: Biodiversity is mostly discussed at the level of species, but genetic variation within species may be as important as variation between species. It enables organisms to adapt to environmental changes. … Many other organisms must be genetically ‘prepared’ to meet environmental changes.
