Conservation Biology 2

Front

What is conservation biology?

Back

Conservation biology is a multidisciplinary field that focuses on the study and preservation of biodiversity, aiming to protect species, their habitats, and ecosystems from extinction and degradation.

What is species richness?

Back

Species richness refers to the number of different species present in a given area or ecosystem, which is a key indicator of biodiversity.

Front

What does habitat fragmentation mean?

Back

Habitat fragmentation is the process by which large, continuous habitats are divided into smaller, isolated patches, often due to human activities, leading to negative impacts on wildlife.

Front

Why is urgency important in conservation efforts?

Back

Urgency in conservation refers to the immediate need to address threats to biodiversity, such as habitat loss or climate change, to prevent irreversible damage to ecosystems.

Front

What is the significance of unique species in conservation?

Back

Unique species, or endemic species, are those that are not found anywhere else in the world; their conservation is crucial for maintaining global biodiversity.

Front

Define ecosystem services.

Back

Ecosystem services are the benefits that humans derive from ecosystems, including provisioning (food, water), regulating (climate, disease), cultural (recreation, spiritual), and supporting services (nutrient cycling).

Front

What is the role of protected areas in conservation?

Back

Protected areas are designated regions that are managed to conserve biodiversity and natural resources, providing safe habitats for species and ecosystems.

Front

Explain the concept of keystone species.

Back

A keystone species is a species that has a disproportionately large impact on its environment relative to its abundance; its removal can lead to significant changes in the ecosystem.

Front

What is the difference between in-situ and ex-situ conservation?

Back

In-situ conservation involves protecting species in their natural habitats, while ex-situ conservation involves preserving species outside their natural habitats, such as in zoos or seed banks.

Front

What are invasive species?

Back

Invasive species are non-native organisms that, when introduced to a new environment, can outcompete native species and disrupt local ecosystems.
