Miscellaneous II
100
A group of populations of different species living close enough to interact
What is Community?
100
A +/- interaction in which the predator kills and eats the prey
What is Predation?
100
The variety of different kinds of organisms that make up the community
What is Species Diversity?
100
The disturbed area can be colonized by a variety of species, which are gradually replaced by other species, which are still replaced by other species.
What is Ecological Succession?
100
The sum of a species' use of the biotic and abiotic resources in its environment
What is Ecological Niche?
200
All interactions including predation, competition, herbivory, and symbiosis.
What are Interspecific Interactions?
200
A +/- interaction that occurs when individuals of different species compete for a resource that limits their growth and survival
What is (Interspecific) Competition?
200
One of the two components of species diversity that signifies the number of different species in the community
What is Species Richness?
200
An event, such as a storm, fire, flood, or drought that changes a community by removing organisms form it or altering resource availability.
What is Disturbance?
200
An outcome in which even a slight reproductive advantage will eventually lead to local elimination of the inferior competitor
What is Competitive Exclusion?
300
How interactions between species affect community structure and organization
What is Community Ecology?
300
A +/- interaction in which an organism eats part of a plant or alga
What is Herbivory?
300
Species in a community that are the most abundant or that collectively have the highest biomass
What are Dominant Species?
300
When ecological succession begins in a virtually lifeless area where soil has not yet formed
What is Primary Succession?
300
The differentiation of niches that enables similar species to coexist in a community
What is Resource Partitioning?
400
Indicates any interspecific interaction in which both species benefit
What is a +/+ interaction?
400
Individuals of two or more species live in direct and intimate contact with one another
What is Symbiosis?
400
One of the two components of species diversity that signifies the proportion each species represents of all individuals in the community
What is Relative Abundance?
400
When an existing community has been cleared by some disturbance that leaves the soil intact.
What is Secondary Succession?
400
The total mass of all individuals in a population
What is Biomass?
500
Name for parasites that live inside the body, and those that feed on the external surface of the host (2 names)
What are Endoparasites and Ectoparasites?
500
An interaction between species that benefits one of the species but neither harms nor helps the other (+/0). These are difficult to document in nature
What is Commensalism?
500
These species aren't necessarily abundant in a community. They exert strong control on community structure not by numerical weight but by their niches
What are Keystone Species?
500
Moderate levels of disturbance can create conditions that foster greater species diversity than low or high levels of disturbance.
What is The Intermediate Disturbance Hypothesis?
500
This describes most communities as constantly changing after being affected by disturbances
What is the Nonequilibrium Model?
