a measure of the genetic variation among individuals in a population
genetic diversity
species diversity
habitat diversity
ecosystem diversity
when a large population declines in number, the amount of genetic diversity carried by surviving individuals is greatly reduced
population bottleneck
extinction
generalists
specialists
(a) is the relative proportion of individuals within the different species in a given area.
Select the ecosystems that would be able to better resist the impact of disturbances or be able to rapidly recover from disutrbances
those with a higher species diversity
those with a lower species diversity
species diversity has no impact on an ecosystem's ability to respond to disturbances
A Giant Panda has a highly specialized diet and can only live in very specific habitats. It can be considered a
generalist species
niche
invasive species
specialist species
What prediction is correct about island biogeography?
Smaller islands have more resources, and will have more biodiversity
Larger islands have more space for resources, but will have less biodiversity due to competition
Islands closer to mainland will be more diverse due to more successful dispersal.
There is more diversity far away from the mainland because some species fly.
What term is used to describe the range of conditions that an organism can withstand?
Ecological Tolerance
Ecological Resistance
Ecological Resilience
Ecological Stability
Which of the following describes an episodic event?
describes an event that occurs or repeats at regular intervals (seasons, night & day)
describes an event that is happening in parts or segments or that kicks off a flow of related events (eutrophication, overhunting by humans)
something that occurs randomly (hurricanes, lightening strikes, etc.)
movement of organisms from one habitat to another
What happens in the zone of optimum range?
All organisms die
Organisms can survive
Organisms can survive and grow, but not reproduce
Organisms can survive, grow and reproduce
A species that out competes native species and causes the native species to die out or go extinct is a:
Dominant Species
Primary Species
Invasive Species
Keystone Species
