|
Competing Intraspecifically
|
Members of the same species compete for limited resources
|
|
|
Fundamental Niche
|
The full range of environmental conditions and resources an organism can possibly occupy and use (when limiting factors are absent)
|
|
|
Realized Niche
|
The part of the fundamental niche that organisms occupy as a result of limiting factors present
|
|
|
Resource Partitioning
|
When resources are limited, species evolve to share the specific resource
|
|
|
Commensalism
|
When one party benefits from the relationship and the other is unaffected
|
|
|
Obligate Mutualism
|
A type of mutualism in which the species involved are in close proximity and interdependent with one another in a way that one cannot survive without the other
|
|
|
Obligate Parasitism
|
A parasitic organism that cannot compete it's life cycle without exploiting a suitable host. If the parasite cannot obtain a host it fails to reproduce
|
|
|
Facultative Mutualism
|
The interacting species derives a benefit from each other but are not fully dependent to the point where they cannot survive without each other
|
|
|
Facultative Commensalism
|
They can but do not have to live without one another
|
|
|
Cryptic Coloration
|
Conceals an animals shape
|
|
|
Aposematic Coloration
|
Markings that warn off predators
|
|
|
Batesian Mimicry
|
A harmless species that has evolved to imitate the warning markings of a harmful species
|
|
|
Eutrophication
|
Addition of artificial or natural substances through detergents, fertilizers, or sewage
|
|
|
Mutualism
|
A symbiotic relationship where both parties benefit
|
|
|
Proxy Indicators
|
Preserved physical characteristics of the past that stand for direct measurements
|
|
|
Keystone species
|
Animals that have a disproportionately large affect on on their environment relative to their abundance
|
|
|
Foundation Species
|
Plays a strong role in the community and it's structure
|
|
|
Dominant Species
|
The species that is most dominant in a community
