Lecture 1 DI Growth Flashcards
1
Q
What are the four primary assumptions of the Lincoln-Petersen estimate?
A
- The population is closed, both geographically and demographically
- Marks are not lost, gained, or overlooked
- All individuals have the same probability of capture (P)
Capture does not affect P
-Capture is = over time
2
Q
What assumptions of the Lincoln-Petersen estimator that are relaxed when using the Mb modle?
A
Probability of capture does not vary among individuals.

Q
What is the BIDE Model
A
Nt+1 = Nt + B + I - D -E
- Population size is affected by only the 4 primary population parameter
- Density-independent (D-I) occur when BIDE do not change as Nt changes
Nt+1 = Nt + Birth + Immigration – Death - Emigration
6
Q
Assumptions of the B-I B-D Balance Model
A
- Population is geographically closed
- Birth and death rates are constant
→Across individuall (age, sex, ect)
→Across time
→Across space
→Across population size ( density-inddependent)
7
Q
Determin Growth rate
A
- Compare population @ 2 times
- Determin difference between b & d
8
Q
Compare population @ 2 times
A
Discrete
λ=Nt + 1 / Nt
9
Q
Determin difference between b & d
A
Continuous
r= b-d or r= (b+i) - (d+e)
10
Q
Move between Discrete and Continuous
A
λ = erand r=lnλ
