Development of Microbial Communities in a Habitat
Succession
preemptive
pioneer organisms alters condition that permits further succession
autogenic
m/os modify the habitat permitting other new populations to develop
allogenic
succession occurs because of environmental factors
Selection strategies
r strategists
high rate reproduction
opportunistic
resource limited
populations are subject to extreme fluctuations
prevail in uncrowded environments
k strategists
reproduce slowly
conservation of resouces
successful in resource limited environment
more stable
permanent members of the community
Biofilm
forms when certain m/os adhere to the surface of some object in a moist environment and begin to reproduce
Types
Simple (monolayer)
Complex (layers of organisms)
advantage
trap nutrients
prevent detachment from surfaces
Consequences
unavailable for attack by immune system
dental carriers
corrosion
slow the flow of water
