Protecting species from extinction
Conservation biology is the scientific study of the nature and status of Earth's biodiversity with the aim of protecting species, their habitats, and ecosystems from excessive rates of extinction. For example, The Mauritius Pink Pigeon (Nesoenas mayeri) survives in the Black River Gorges of south–west Mauritius and on Ile aux Aigrettes, just off the eastern coast. It is an endangered species threatened by a continuing decline in the quality of suitable habitat. The present populations could not be maintained without conservation and management efforts. It is endemic to Mauritius. This pigeon was photographed on a feeding station managed by the Mauritian Wildlife Foundation.
Conservation and Restoration Ecology
Biology is the science of life. Our final chapter in Ecology and Biosphere focuses
on two disciplines that seek to preserve life. Conservation biology and restoration
Conservation biology is the scientific study of the nature and status of
Earth's biodiversity with the aim of protecting species, their habitats, and ecosystems
from excessive rates of extinction. Conservation biology integrates ecology (including
behavioral ecology), physiology, molecular biology, genetics, and evolutionary biology
to conserve biological diversity at all levels. Efforts to sustain ecosystem processes
and stem the loss of biodiversity also connect the life sciences with the social
sciences, economics, and humanities. Conservation
biology is a multidisciplinary science that assists conservation practitioners in
addressing the loss of our biological resources.
Conservation biology has two central
goals: to evaluate human impacts on biological diversity, and to develop practical
approaches to prevent the extinction of species and maintain the integrity of ecosystems.
Restoration ecology is the scientific study of repairing disturbed ecosystems through
human intervention. Restoration ecology applies ecological principles in an effort
to return degraded ecosystems to conditions as similar as possible to their natural,
predegraded state. Where conservation biology is often focused on preventing ongoing
degradation, restoration ecology seeks to actively reverse such degradation.
