Adaptations and Natural Disruptions
A bird flying south for the winter is an example of this type of adaptation.
What is migration/ behavioral adaptation?
What are invasive species?
An organism that colonizes barren land is called this.
What is a pioneer species?
A natural disruption that occurs with no set frequency on any scale of time.
What is random?
Range of conditions that an organism can endure before injury or death occurs.
Ecological tolerance
An organism that gives clues to the health of an ecosystem.
What is an indicator species?
In Part B/2 of our Survival of the Sweetest lab, removing the predatory starfish completely changed the behavior of the 5 other species as they played a vital role. This mean the starfish was considered a ___________ species.
Keystone
Islands are made up of these types of organisms due to low diversity in resources.
What are specialist species?
Recolonization of an ecosystem after a wildfire.
What is secondary succession?
Tidal movements, recurrent fires in chaparral, monsoon seasons
What is a periodic disturbances?
_________ to the mainland has an effect on the biodiversity of an island.
What is size/proximity?
The most biodiverse and active an ecosystem would be is called what?
What is the climax community?
Sea level has varied over time due to the melting of this.
What is glacial ice?
This is a way that organisms get to an island.
What is flying, floating, humans, ect.
This realization/ theory/ idea proposes that species diversity is generally maximized if disturbance is neither too rare nor too frequent because species that thrive at both early and late successional stages can coexist.
At low disturbance frequency and/or intensity, competitively dominant species exclude competitively inferior species. With high disturbance frequency and/or intensity, only species that quickly colonize and reach maturity survive.
What is the Intermediate Disturbance Hypothesis
