Biodiversity
This type of biodiversity refers to variation in genes within a population
Genetic diversity
These are the benefits humans receive from functioning ecosystems
Ecosystem services
This term describes the full range of environmental conditions a species can survive in
Range of tolerance
This is a type of event that occurs on a regular, predictable schedule
Periodic disruption
This is what it is called when an area develops from bare rock with no soil
Primary succession
This term describes the number of different species found in an ecosystem
Species richness
This type of ecosystem service includes recreation, tourism, and education
Cultural services
This is the range of conditions where a species grows and reproduces best
Optimal range
This is an inherited trait that increases an organism’s ability to survive and reproduce in a specific environment
Adaptation
This process occurs after a disturbance when soil remains
Secondary succession
This term refers to how evenly individuals are distributed among species
Species evenness
This category of ecosystem services provides food, water, and raw materials
Provisioning services
This zone occurs when organisms survive but experience reduced growth or reproduction
Zone of physiological stress
This is a type of event that randomly happens with no predictable pattern
Random disruption
These organisms are the first to colonize newly exposed land
Pioneer species
This event occurs when a population experiences a sudden decline that reduces genetic variation
Bottleneck
This type of service includes climate regulation and air purification
Regulating services
This zone occurs when environmental conditions result in death
Zone of intolerance
This term describes an ecosystem’s ability to return to original conditions after disturbance
Resilience
This is the stable, mature community that forms at the end of succession
Climax community
This level of biodiversity increases when a region contains many different types of habitats
Ecosystem diversity
This service category includes processes we do ourselves, making them less costly and easier for us
Supporting services
This is most likely to happen to a population when climate change pushes conditions beyond tolerance limits
Population decline
This environmental factor favors individuals with traits that improve survival
Selective pressure
This theory explains why large islands close to the mainland support more species
Island biogeography
