Biodiversity
Biodiversity refers to the variety and variability of life forms within a given species, ecosystem, or planet. It encompasses three main levels:
- Genetic diversity: The genetic variation that occurs among individuals in a population.
- Species diversity: The variety of different species within an area.
- Ecosystem diversity: The variety of ecosystems within a region.
Key Concepts
- Endemism: The degree to which organisms are unique to and exclusive for a defined geographic location, such as an island or other isolated areas like the Galápagos Islands.
- Conservation biology: A branch of biological science that aims to conserve endangered species and their habitats.
- Ecological niche: The role or job of a species in its environment; how it makes a living.
- Rewilding: Active restoration of degraded ecosystems to restore natural processes and biodiversity, often involving the reintroduction of native species or innovative management of invasive flora.
Case Studies & Applications
- Banks Peninsula Rewilding: Hugh Wilson’s Gorse-Based Ecosystem Restoration: A notable example of unconventional ecosystem restoration where botanist Hugh Wilson utilized gorse (an invasive thorny weed) rather than eradicating it, facilitating the recovery of native vegetation on degraded farmland in New Zealand.
