Study Notes
- Biodiversity is the variety of species on Earth
- It includes species richness, abundance, genetic and ecological variability
- Simpson's index of diversity is a measure of an ecosystem's biodiversity
- A low index of diversity suggests few successful species dominating or a hostile environment
- A high index of diversity suggests a more stable ecosystem with more successful species and ecological niches
- Humans have influenced the environment more than any other species
- Habitat loss, overexploitation, and introduction of exotic species are some of the threats to biodiversity
- Genetic variability is important for biodiversity as it helps populations adapt to environmental changes
- Rhododendron bushes prevent other plants from growing and dominate the area, leading to low index of diversity
- Tropical rainforests are an example of high biodiversity.
