Species diversity plays a crucial role in maintaining the balance and stability of ecosystems. The presence of a variety of species with different ecological niches and functions contributes to the overall resilience of the ecosystem, allowing it to adapt to environmental changes and disturbances.

While overpopulation can have various negative impacts on the environment, it is not directly considered a major threat to species diversity in the same way as habitat loss, invasive species, and climate change.

Extermination refers to the deliberate or unintentional elimination of a significant number of individuals of a particular species, often leading to its decline or even extinction.

CITES is an international agreement that regulates the trade of endangered species and their products, aiming to prevent their exploitation and contribute to their conservation.

Reintroduction involves the intentional release of individuals of a species into an area where it was previously found, with the aim of establishing a viable population.

While genetic modification has applications in various fields, it is not typically considered a strategy for conserving species diversity in the context of conservation biology.

Conservation refers to the protection, management, and sustainable use of natural resources, including the preservation of species diversity and their habitats.

The domestic dog is not considered an endangered species as it is a domesticated animal and not native to any particular ecosystem.

Restoration involves the active process of repairing and recovering a damaged ecosystem to its original or desired state.

Natural selection is a process that drives evolution and adaptation within species, and while it can lead to the extinction of certain populations, it is not typically considered a direct cause of species extinction in the context of conservation biology.

Conservation encompasses a wide range of actions aimed at protecting and managing species and their habitats to prevent their decline and extinction.

Tundra regions are not typically considered biodiversity hotspots as they are characterized by low species diversity compared to other ecosystems.

Invasive species are non-native species that have been introduced to an ecosystem and have the potential to cause harm to native species and the environment.

While genetic modification has applications in various fields, it is not typically considered a strategy for mitigating the impacts of climate change on biodiversity in the context of conservation biology.

Sustainability refers to the practice of managing resources and activities in a way that meets the needs of the present without compromising the ability of future generations to meet their own needs.
