Island Biogeography

Front

What is the theory of island biogeography?

Back

The theory of island biogeography explains how the number of species on an island is determined by the island's size and its distance from the mainland.

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

Back

Species richness is affected by island distance from the mainland and island size.

Front

What is genetic drift?

Back

Genetic drift is a change in the genetic composition of a population over time due to random mating.

Front

What is the relationship between island size and species richness?

Back

Larger islands tend to have higher species richness compared to smaller islands.

Front

What is the relationship between island distance from the mainland and species richness?

Back

Islands that are closer to the mainland generally have higher species richness than those that are farther away.

What is the bottleneck effect?

Back

The bottleneck effect is a sharp reduction in the size of a population due to environmental events or human activities, leading to a loss of genetic diversity.

What is the founder effect?

Back

The founder effect occurs when a small group of individuals establishes a new population, leading to reduced genetic variation.
