For "closed populations", replenishment is often linked to local resource availability
This, in turn, may be influenced by population size.
When do you expect density dependence and when do you expect density independence in closed populations?
For "open populations", replenishment is related to patterns of production and dispersal.
What influences production?
What influences dispersal?
Limited supply may keep populations well below their carrying capacity.
The implications of "recruitment limitation"
For populations
For communities (more later)
How does longevity (survivorship) influence our thinking about recruitment limitation?
Implications for population persistence and thinking about local "extinctions"
Evidence from studies of coral reef fishes provide data on these topics.
Variation in "planktonic larval duration" (PLD) and biogeography
What else can otoliths tell us?
