Intro to Biodiversity
The variety of life on Earth
What is biodiversity?
Something the ecosystem does for free that would cost a lot to do ourselves
Ecosystem services
The study of the distribution of species and ecosystems across the planet
What is Biogeography?
The range of conditions that a species can live and reproduce in
What is tolerance?
Give an example of a natural disruption
Earthquakes, tornado, etc.
What are the three types of biodiversity?
Genetic, species, and habitat
Name 2 of the types of service
Supporting, regulating, provisioning, or cultural
What is an endemic species?
Behavioral, structural, physiological, or genetic
Give an example of a human made disruption
Deforestation, pollution, etc.
Explain the bottleneck effect
A significant loss of pop. leads to a loss in diversity, leaving the species more vulnerable
List the 2 ecosystem services not already said
supporting, regulating, provisioning, cultural
How does island size affect biodiversity?
List the 2 unnamed types of adaptations
Behavioral, structural, physiological, or genetic
What is a keystone species?
Keeps the ecosystem together
Explain the Founder Effect
A small part of the pop. becomes separated from the group, losing genetic diversity
Give an example of a cultural service
Camping, rafting, swimming, etc.
What does "evolutionary process" mean?
The development of island-specific traits that contribute to the biodiversity of the island; the Founder Effect
What is a specialist species?
Highly adapted to a specific environment and has a narrow range of tolerance
Give an example of an adaptation of an animal
Why is a lack of biodiversity bad?
It will harm ecosystems and eventually our way of life
Give an example of a provisioning service
Food, water, air, shelter, etc.
How does isolation affect biodiversity?
Isolated islands will have less biodiversity because fewer species can get there
What is a generalist species?
Highly adaptable to many environments and has a wide range of tolerance
Compare periodic, episodic, and random system processes
Periodic happens in cycles like seasons, episodic is irregular but predictable, and random is unpredictable like a volcano
