Biodiversity II
Genetic variation amongst individuals in a population is called this.
What is genetic diversity?
This type of species is more likely to be found on islands.
What are specialist species?
This is the name of the island group where Charles Darwin conducted his studies on evolution
What are the Galapagos Islands?
An individual’s ability to survive and reproduce is called this
What is fitness?
This type of succession starts with a lifeless area.
What is primary succession?
This type of species can live under a narrow range of biotic and abiotic conditions.
What is a specialist species?
Comparing two islands of differing sizes, this is more likely to have a more diverse variety of life.
What is the bigger one?
The process in which humans determine which individuals to breed is called this
What is evolution by artificial selection?
When individuals that have evolved in a different location can no longer breed successfully with similar individuals from their original location, they have become this
What is a new species?
This type of succession starts with soil already present.
What is secondary succession?
This specific type of event can cause a reduction in genetic diversity.
What is a bottleneck event?
Comparing two islands that have been populated for different amounts of time, this is more likely to have a more diverse variety of life.
What is the older one?
The processes that alter the genetic composition of a population over time, but the changes are not related to differences in fitness among individuals, are called these
What is evolution by random processes?
A trait that improves an individual’s fitness is called this
What is an adaptation?
Wolves in Yellowstone National Park are an example of this type of Species
What is a keystone species?
The abundance of individuals within each species present is termed this.
What is species evenness?
Comparing two islands of differing distances from the mainland, this is more likely to have a more diverse variety of life.
What is the closer one?
The process in which the environment determines which individuals survive and reproduce is called this
What is evolution by natural selection?
The process by which individuals move from one population to another, as a result altering the genetic composition of both populations is called this
What is gene flow?
A species that can colonize new areas rapidly and grow well in full sunshine is called this
What is a pioneer species?
With regard to genetic and species diversity levels (levels being high or low), this ecosystem would respond best to disruption.
What is one with both high genetic and species diversity?
As we move in this direction, species richness increases.
What is equatorward, or from the pole to the equator?
Adaptations are not a factor in this type of evolution
What is evolution by random processes?
Through this process, individuals with a beneficial adaptation survive and those lacking it do not
What is selective pressure?
A climax community can be described as this.
What is a stable group of plants and animals that is the end result of their succession process?
