Island Biogeography
According to island biogeography, islands that are this distance from the mainland generally receive more immigrant species.
What is closer to the mainland?
recreation and scenic area for tourism
What are cultural ecosystem services
This zone represents the range of environmental conditions where an organism can survive and reproduce most successfully.
What is the optimum zone
Plants that will appear near the end of the ecological succession cycle
What are larger plants like trees
Scientists monitor this type of species because its presence, absence, or population changes can provide information about the health or condition of an ecosystem.
What is an indicator species
Between two islands of equal size, this island would generally have the least number of species.
What is farther from the mainland
Food, timber, fresh water, and medicinal plants are all examples of this category of ecosystem service.
What is provisioning services
In this zone, an organism can survive, but it experiences stress and has reduced growth or reproduction.
What is the zone of physiological stress?
These organisms are often the first to colonize bare rock during primary succession and help begin soil formation.
What is lichen
This type of species has a disproportionately large effect on its ecosystem compared with its abundance. Removing it can cause major changes in the community.
what is a keystone species
small populations are more vulnerable to unpredictable events leading to this
what is extinction
Wetlands filtering pollutants from water and forests absorbing carbon dioxide are examples of this category of ecosystem service.
What are regulating services?
In these zones at the extreme ends of the tolerance curve, an organism cannot survive.
What are the zones of intolerance?
After a disturbance, an ecosystem recovers much faster when this resource remains because plants can regrow and seeds can germinate.
what is soil
These areas contain exceptionally high numbers of species found nowhere else and face significant threats from human activities.
What are biodiversity hotspots
A large forest is divided by roads and development into several smaller, isolated patches. This process can reduce biodiversity by isolating populations and is called ....
What is habitat fragmentation
Soil formation, nutrient cycling, and primary production are examples of this category of ecosystem services.
What are supporting services
Temperature, pH, salinity, and dissolved oxygen can all affect an organism's ability to survive. These environmental conditions are known as this.
What are abiotic factors?
when plants that grow best in full sun appear
what is the beginning of ecological succession
When the removal of a top predator causes changes in herbivore populations and then affects vegetation and other organisms farther down the food web, this is called this.
What is a trophic cascade
A species that can survive only within a narrow range of environmental conditions and relies on a specific habitat or food source is called this.
What is a specialist species
This term describes environmental changes or impacts caused by human activities, such as deforestation, pollution, and urbanization.
What are anthropogenic activities?
An aquatic organism has a tolerance range for water temperature. At 10°C and 30°C it cannot survive; at 20°C it thrives; and between these temperatures it experiences increasing stress as conditions move away from 20°C. On a bell curve, the areas near 10°C and 30°C would represent this zone.
What is the zone of intolerance?
When the community reaches its most productive state
what is climax community
When a population's size is dramatically reduced by a natural disaster or other event, the resulting reduction in genetic diversity is called this type of effect....
What is the bottleneck effect
