Questions and Answers

What is temporal isolation?

A type of isolation that occurs when populations do not interbreed with each other because they reproduce at different times.

What is mechanical isolation?

A type of isolation that occurs when different species are isolated by their mechanics.

What is behavioral isolation?

A type of isolation in which two allopatric species do not mate because of differences in courtship behavior.

What is reproductive isolation?

A type of isolation that occurs when two groups of animals live close enough to one another to interact, but are unable to interbreed. Signup and view all the answers

What is ecological isolation?

A type of isolation when organisms have the same range but do not come across one another because they are eating different foods or living in different habitats. Signup and view all the answers

What is geographic isolation?

A type of isolation when a population is split apart by a physical barrier such as a river, ocean, or mountain range. Signup and view all the answers

Study Notes

Types of Isolation

Temporal Isolation: Populations do not interbreed as they have different reproductive times, preventing mating even if they coexist during the same period.
Mechanical Isolation: Different species remain isolated due to incompatibilities in their reproductive organs, which prevents successful mating.
Behavioral Isolation: Allopatric species fail to mate due to differences in courtship rituals or behaviors, even when they inhabit the same region.
Reproductive Isolation: Occurs when two groups are in proximity but cannot interbreed, leading to genetic divergence despite potential interaction.
Ecological Isolation: Species sharing a geographic range do not meet due to differences in habitat preferences, food sources, or mating sites.
Geographic Isolation: Physical barriers, such as rivers, mountains, or oceans, split populations, preventing gene flow and leading to speciation.
