Discuss Concepts How do concepts from population genetics, metapopulation dynamics, and beta-diversity apply to the design of nature preserves? Do they suggest different ideal designs for nature preserves?

Summary Introduction

To review:

The concepts from population genetics, metapopulation dynamics, and beta-diversity that apply to the design of nature preserves and whether they suggest a different ideal design for nature preserves or not.

Introduction:

The maintenance and preservation of biodiversity by interdisciplinary science are known as conservation biology. The primary tool used by the scientists in preserving the nature is systematics and knowledge of biodiversity.

Explanation

The genetic variability is reduced when a population is reduced to small size, due to genetic drift, and because of other evolutionary forces in operation to adapt to a changing environment. The survival potential is reduced with the loss of even a small fraction of species genetic diversity. Therefore, by increasing and maintaining the genetic variation of threatened or endangered species, such a problem can be avoided.

The number of species increasing in a particular area with a different habitat and small-scale environment is described by beta-diversity. Thus, with the increase in the size of the area, the number of environment features also increases...
