the collected data is a representation of the general population
What is sampling theory?
A prediction of how a population will change over time
What is a model population?
number of gametes per individual (usuallyegg per female, sometimes sperm per male), predictspopulation's max growth potential
what is fecundity?
the deaths from a new cause (like predation, disease, or climate stress) are added on top of existing deaths, increasing the total mortality rate of the population.
What is additive mortality?
Yearly survey of waterfowl and migratory game birds.
What is the Harvest Information Program of 1999?
the maximum number of individuals a population can sustain
r: the "per head" maximum potential growth rate
what is 'k" or carrying capacity
When deaths from one cause replace deaths that would have happened anyway from another cause.
What is compensatory mortality?
The comparison of relative abundance over space/time
What is indices?
