Population - correct answer ✔✔a group of organisms, usually of the same species, occupying a defined
area during a specific time
Population Growth - correct answer ✔✔animals tend to give birth to many more individuals than will
survive to breeding age
Exponential Equation - correct answer ✔✔if deaths did not offset births, the result would be an infinitely
growing population dN/dt=rN
dN=change in #
dt=change in t
r="per head" max potential growth rate
N=# individuals in the population
Logistic Equation - correct answer ✔✔most populations cannot have an unrestricted rate of growth
forever
dN/dt=rN((K-N)/K)
Sigmoid "S"-shaped curve
Middle of graph is the inflection point
Carrying Capacity - correct answer ✔✔K=maximum # of individuals the environment can sustain
As the population (N) approaches K...
Changes over time. Food, cover, water...
Maximum Sustained Yield - correct answer ✔✔largest value is obtained when N is half of the carrying
capacity
Max yield at~0.56 of K
,Density-Dependent Factors - correct answer ✔✔a factor that causes higher mortality or reduced birth
rates as a population becomes more dense
Food supply, predation, disease, territorial behavior
Density-Independent Factors - correct answer ✔✔a factor that causes higher mortality or reduced birth
rates independent of population density
Periphery of the range: cold, rain, floods
Hunting Mortality - correct answer ✔✔effects of hunting are often thought of in terms of additive or

Ruffed Grouse mortality rate - correct answer ✔✔Public: Hunting (73% Adult 56% Juvenile) Predation
(16% 35%)
Private: Hunting (13% Adult 9% Juvenile) Predation (27% 43%)
What type of mortality can hunting be on public land? - correct answer ✔✔may be completely additive
