Biodiversity is the variation of life forms within a given ecosystem, biome, or for the entire Earth. Biodiversity is often used as a measure of the health of biological systems. The biodiversity found on Earth today consists of many millions of distinct biological species, which is the product of nearly 3.5 billion years of evolution.
The term was used first by wildlife scientist and conservationist Raymond F. Dasmann in a lay book advocating na...

In 2005, Rob Dunn, J. P. Lessard, Matt Fitzpatrick, Nate Sanders and Ed Laurent began the North American Ant Database with the goal of understanding patterns of diversity and distribution in North American ants. We have now broadened this database and associated research through a... -
Macroecology
Macroecology is the subfield of ecology that deals with the study of relationships between organisms and their environment at large spatial scales to characterise and explain statistical patterns of abundance, distribution and diversity. The term was coined by James Brown of the University of New... -
Biogeography
Biogeography is the study of the distribution of biodiversity over space and time. It aims to reveal where organisms live, and at what abundance. Biogeography does more than ask Which species? and Where. It also asks Why? and what is sometimes more crucial, Why not?. The patterns of species... -
