Community Ecology
Predator - Prey Interactions
Functional Response
intake response of a consumer as a function of food density
Prey - Dependent
dependence on prey density
Zero Growth isocline
The line indicating population stability
Paradox of Enrichment
overexploitation of the prey by the predator leading to both populations being lost
Maximum sustained yield
harvesting of just enough of a species to keep the population stable
Fixed quota harvest
the controlling of harvest in order to maintain population
Optimal foraging theory
interaction between factors in order to study the diets of herbivores
Optimal diet theory
predictions based on the diets of herbivores
Exploitation Competition
Competition occurs when the organisms actually consume a shared resource
Interference Competition
one organism restricts the use of a resource of another organism
Invasive
Species that that can increase from a very low population density even with competitors present
Resource
any substance or factor that can lead to increased growth rates
Apparent Competition
Plants are not actually competing for a resource
Diversity
Community
a group of species that occur together at the same time and place.
Succesion
sequence of changes
Species- area Relationship
The Relationship between area and species richness
Species abundance distribution
we can plot the number of species in each abundance class and obtain
Beneficial Interactions Between
Mutualism or Mutualistic Relationship
Two organism interact and benefit from the interaction
Facilitation
One organism helps without receiving any benefit
Nurse Plants
Plants that alter a small area of a habitat immediately below themselves
Primary Succession
Organisms establish on newly created substrates
Metapopulations in Patchy Environments
Metapopulation
Gene flow between the patches , the local populations constitute
Source Habitat
high quality patch
SINK Habitat
low quality patch
