The first of these items, defining what we want to conserve, is complicated by the remarkable diversity of the organisms themselves. This is a product of the genetic diversity of the organisms.

Analyses of the patterns of biogeography can be divided into historical biogeography and ecological biogeography. Historical biogeography uses past events in the geological history of the Earth and ecological biogeography examines the dispersal of organisms (usually individuals or populations) and the mechanisms that influence this dispersal to explain patterns in the spatial and temporal distributions.

An ecosystem can exist at any scale, for example, from the size of a small tide pool up to the size of the entire biosphere. However, lakes, marshes, and forest stands represent more typical examples of the areas that are compared in discussions of ecosystem diversity.

In popular usage, the word biodiversity is often used to describe all the species living in a particular area. If we consider this area at its largest scale - the entire world - then biodiversity can be summarized as "life on earth." However, scientists use a broader definition of biodiversity, designed to include interactions with the abiotic aspects of their environment.

While it is important to know the total number of species of Earth, it is also informative to have some measure of the proportional representation of different groups of related species (e.g.

What if a species-poor area actually is quite evolutionarily distinct from others? Similarly, what if your most species-rich site is comprised of a swarm of species that have only recently diverged from one another and are quite similar to species present at another site? These questions allude to issues of biological diversity at higher taxonomic leve

Therefore, assemblages of different ecosystems (the physical environments and the species that inhabit them, including humans) create landscapes on Earth. Although there is no standard definition of the size of a landscape, they are usually in the hundred or thousands of square miles.
