Why are tropical rain forests significant in terms of biodiversity?

Back

Tropical rain forests are home to the greatest number of species on Earth and are experiencing the highest rates of extinction due to habitat loss and climate change.

Front

What is a biodiversity hotspot?

Back

A biodiversity hotspot is a biogeographic region with a significant amount of biodiversity that is under threat from human activities.

Front

What percentage of species are expected to become extinct between 1900 and 2100?

Back

Biologists estimate that 25% of species are expected to become extinct during this period.

Front

What role do seed banks play in biodiversity conservation?

Back

Seed banks preserve genetic material from a wide variety of plant species, helping to protect against extinction and maintain biodiversity.

Front

How can creating large parks or preserves help biodiversity?

Back

Large parks and preserves protect habitats, allowing species to thrive and maintain ecological processes, thus slowing the loss of biodiversity.

What species was removed from the Channel Islands to help the Island Fox?

Back

The Golden Eagle was removed from the Channel Islands to allow the Island Fox population to recover.

Front

What is the difference between species richness and species evenness?

Back

Species richness refers to the number of different species in a given area, while species evenness measures how evenly individuals are distributed among those species.

Front

What are the main threats to biodiversity?

Back

Main threats include habitat destruction, climate change, pollution, overexploitation, and invasive species.

Front

What is the significance of genetic diversity within a species?

Back

Genetic diversity allows populations to adapt to changing environments and resist diseases, enhancing survival and resilience.
