Community Ecology
Predator-Prey interaction
Predator Selection Among Multiple Prey
3 factors for predator's choice
decision to attack the encountered prey
Attacked prey succesfuly eaten
Individual Prey encountered
Optimal foraging theory
Optimal diet model
Apparent Compettition
Link Title
One predator, one prey
Paradox of enrichment
Maximum sustained yield
Zero growth isocline
Fixed effort harvesting
Prey dependent
Fixed quota harvesting
Functional response
Primary producer
#
Primary consumer
Competition Between species
Exploitation competition
Consumption of shared resource making it less available
Interference competition
One organism restricts another's access to resources
Metapopulations in patchy Environments
Common model
Many discrete patches
Some occupied, wheres as others are not
Empty ones colonized by migration from occcupies ones
Migration corridors
unconnected wigned patch
Unconnected rectangle patch
Connected patch
Wing
Populations within individual patches have a probability of going extinct
Habitat
Source Habitat
Sink habitat
Fugitive species
#
survives
Coloniation
Flourishes temporarily
Asisted dispersal
Asisted migration
Captured in one and released in a new area
Interconnectedness of species: Food chains and food webs
Simple community
Primary consumers
Secondary consumers
Primary producers
Food chain
Keystone species
Food web
a system of interlocking and interdependent food chains.
Energy flow web

Habitat loss
Habitat fragmentation
Succession
Beneficial interactions between species
Mutualism
Mutualistic relationship
Both are benefited
No preying
No competiton
Facilitation
One helps other
One recieves benefit
No competition nor preying
one facilitates the presence of the other
Primary succession
