What Is Conservation Biology? Conservation biology aims to preserve biodiversity using several approaches including, genetics, evolution, population ecology, biogeography, wildlife management, economics, and sociology. Conservation biology is guided by three major principles: Evolution unites biology; The ecological world is dynamic; Humans are part of ecosystems. endemic How Do Biologists Predict Changes in Biodiversity? The number of extinctions during the remainder of this century cannot be predicted accurately because: 1. The number of species is unknown; 2. It is difficult to determine when a species becomes extinct. 3. We do not know what will happen in the future ; global warming; 4. It cannot be predicted how adaptable organisms will be to climate change. The species–area relationship is one way to predict extinctions. On average, a 90 percent loss in habitat results in a 50 percent loss of species. The rate of loss of tropical evergreen forest is about 2 percent per year.
