What is biodiversity?

The variety of life on Earth at all levels, including species, genetic, and ecosystem diversity.

What are the three main types of biodiversity?

Species diversity, genetic diversity, and ecosystem diversity.

What are provisioning services in biodiversity?

Services that provide resources like food, medicine, and timber.

What does Simpson's Diversity Index measure?

It measures biodiversity by considering both species richness and evenness.

What is the formula for Simpson's Diversity Index?

$D = 1 - \sum_{i=1}^{R} p_i^2$, where $p_i$ is the proportion of individuals of species $i$.

What is speciation?

The process by which new species arise.

What are the types of speciation?

Allopatric, sympatric, and parapatric speciation.

What are the five major mass extinction events?

End-Ordovician, Late Devonian, End-Permian, End-Triassic, End-Cretaceous.

What are the main human activities threatening biodiversity?

Habitat destruction, pollution, overharvesting, climate change, and invasive species.

What is the IUCN Red List?

A comprehensive inventory of the global conservation status of biological species.

What are the categories of the IUCN Red List?

Extinct, Extinct in the Wild, Critically Endangered, Endangered, Vulnerable, Near Threatened, Least Concern.

What are biodiversity hotspots?

Areas that are rich in biodiversity but face severe threats, like tropical rainforests.

What are the arguments for biodiversity conservation?

Ecological, economic, ethical, and aesthetic/cultural reasons.

What is the Convention on Biological Diversity (CBD)?

A global agreement addressing all aspects of biodiversity.

What are Marine Protected Areas (MPAs)?

Areas that restrict fishing and other activities to protect marine biodiversity.

What is community-based conservation?

An approach that involves local communities in conservation efforts for long-term success.

What are some threats to coral reefs?

Ocean acidification, rising sea temperatures, overfishing, and pollution.

What is a key strategy for coral reef conservation?

Establishing Marine Protected Areas and coral restoration efforts.
