Cards

Term
Primary Production
Definition
-Typically how much energy is available from the sun, the closer the equator the more energy.
-Availability of key nutrients (water, nitrogen, etc.)
-Can not be productive of both of these factors.

-Seen as father of national parks in US
Term
Ecological Niche
Definition
-The ecological role and space that organism occupies in an ecosystem.
-The place where the organism lives within the environment in relation to ecological gradients.
-The roles that an organism plays (providing shelter) food source, primary producer etc.)

No two organisms can occupy the same space in an ecosystem at the same time.
Term
Biology
Definition
The study of life.
Term

Definition
Abiotic and Biotic
Term
Valuing Biodiversity
Definition
A. Use value (direct value of use)
B. Functional Value - Wetland improvment of water quality (still assign $)
C. Non - Use Values Including...
I Option value ( value for future used by individuals)
II Existence value (to know it remains on the planet)
III Bequest value (one day this will all be yours)
Term
Habitat
Definition
The Place where an organism lives.
Term
5 Aspects of Habitat
Definition
1. Food
2. Water
3. Thermal Cover
4. Escape Cover
5. Space
Term
Parasitism
Definition
A relationship between two organisms where on derives benefit at a cost to the other.
Term
Mutualism
Definition
A biological interaction between two or more species where both benefit.
Term
Commensalism
Definition
A biological interaction between two or more species where on species benefits and there is no cost to the other.
Term
Home Range
Definition
The area within which an individual typically travels in its daily activities. (Characteristic within vertebrates, can change during the year)
Term
Territory
Definition
An area (typically with a home range) that an individual will defend from others of its land.
Term
Dispersion
Definition
The spatial distribution of individuals within a population.
Term
Ecological Gradients
Definition
-Life-history characteristics
-Habitat
-Trophic Position
-Geographic Range
Term
Competition
Definition
Competition occurs when two or more organisms living in the same environment/area have over lapping niche requirements.
Term
Interspecific Competition
Definition
Competition between or among different species. (wolves vs. coyotes)
Term
Intraspecific Competition
Definition
Competition within species. (wolves vs. wolves)
Term
Species Interactions (5 factors)
Definition
-Predation
-Competition
-Parasitism
-Mutualism
-Commensalism
Term
Fundamental Niche
Definition
The niche occupied by an organism without competition.
Term
Niche Segregation
Definition
The tendency for species that live in the same area and require similar resources to differ along one ore more dimensions of a niche.
Term
Realized Niche
Definition
The niche occupied by an organism with competition.
Term
Exotic Invasive
Definition
A species introduced by us to a new area.
Term
Native Invasive
Definition
A species that expands its range due to human - induced habitat change.
Term
Biological Control
Definition
Controlling an invasive species by introducing a biological predator.
Term
Law of Tolerance
Definition
Species will only be found within the ecological minimums and maximums they can withstand.
Term
Limiting Factors / Resources
Definition
A single component of habitat that limits population growth. (ex. Wolverine = needs space, Tern = exclusive nesting)
