Island Biogeography & Biodiversity

Front

What is Island Biogeography?

Back

A field of study that examines the ecological relationships and species diversity on islands, focusing on how island size and distance from the mainland affect species richness.

Front

What are natural disturbances that can disrupt ecosystems?

Front

What is biodiversity?

Back

The variety of different organisms found in an ecosystem.

Front

What is habitat diversity?

Back

The number of different habitats in a region.

Front

What is the purpose of building wildlife corridors?

Back

To overcome habitat fragmentation and allow species to move between habitats.

Front

What factors affect species richness according to the theory of island biogeography?

Back

Island distance from mainland and island size.

Front

Define ecological tolerance.

Back

The range of environmental conditions that a species can withstand.

Front

What is habitat fragmentation?

Back

The process by which large habitats are broken into smaller, isolated patches.

Front

What is an ecological niche?

Back

The role and position a species has in its environment, including all interactions with biotic and abiotic factors.

Front

What is the significance of keystone species?

Back
