Chapter 26
Competition between species
#
Exploitation Competition
organisms consume a shared resource
Interference Competition
one organism restricts another organism access to resources
Invasive Competition
#
If species increase even with low population density
Apparent Competition
One species increase and other decrease but not in actual competition
Metapopulation
Local populations interconnected
Source habitat-
High quality patch
Sink Habitat
Low-quality patch
Fugitive Species
Species survives by colonizing new patches
Metapopulation Model
Mutualistic Relationship
Facilitation
#
If one organism helps another without receiving benefit
Primary Succession
Nurse Plants
Alter a habitat so that it is more favorable to survival
Food Chain
#
Food web
Keystone species
#
Community
Succession
Climax Community
Community restoration
Habitat Loss
Habitat Fragmentation
Diversity

Scale

Scale
Species-area relationship
#
relationship between area and species richness
Species area relationship graph
Species abundance distribution
plot of the number of species in each abundance class
Predator-Prey Interaction
Functional Response
Feeding rate and handling time
Prey-dependent
Prey density
Zero growth isocline
#
shows the effects of prey density
Paradox of enrichment
If prey conditions improve, the predators overexploit the prey so both species will be lost
Maxium Sustained Yield
Point where population density is keeping the species stable
Fixed effort harvesting
Population health is determined by prey density
Fixed quota harvesting
Harvesting is allowed when population is healthy
