What is the Bottleneck effect?
The effect that occurs when a major event causes a decrease in genetic/species variety.
What is the difference between Species Richness and Species Evenness?
Species Richness describes how many different species are in an area while Species Evenness describes the proportion of different species in an area
What are the four types of ecosystem services?
Provisioning, Supporting, Regulating, Cultural
What is the difference between a Regulating and a Supporting ecosystem service?
No ecosystem can survive without Supporting services, Regulating services help those ecosystems further develop and thrive
What are the three areas in a Range of Tolerance?
Zone of intolerance, physiological stress, and optimum
What is the difference between resistance and resilience?
Resistance measures how much a disturbance affects the flow of energy and matter in an ecosystem, while Resistance measures how fast it takes an ecosystem to recover from a disturbance
What is the Intermediate Disturbance Hypothesis?
States that the maximum species diversity is achieved through moderate levels of disturbance to keep competition levels at bay
What is the difference between Primary and Secondary Succession?
Primary Succession lacks soil and takes much longer to thrive due to this. Secondary Succession follows the same latter steps of Primary Succession but occurs with pre-existing soil.
What are Pioneer Species?
Species like lichens, mosses, and fungi that reproduce quickly, allowing them to contribute to the initial formation of soil in Primary Succession
What are the two communities found at the beginning and end of a succession cycle?
Pioneer Community, Climax Community
