16. Population Modelling (BIDE, Population Size, Net Reproductive Rate)

Question 1

Model

Answer 1

Formalized conceptualization of ecological processes, usually quantitative

Question 2

What are the ways populations can increase or decrease

Answer 2

Increase:
Birth, immigration

Decrease:
Death, emmigration

Question 3

Formula for per capita population changes

Answer 3

Nt+1= Nt + Nt(b + i − d − e)
b,i,d,e= per capita birth, immigration, death, and emmigration

Question 4

Density dependent vs density independent factors

Answer 4

Dependent: biotic
Independent: abiotic

Question 5

Fecundity schedule

Answer 5

a tabulation of birth rates for females of different ages in a population, estimates rate of change in a population

Question 6

Net reproductive rate

Answer 6

R0, average number of offspring produced by a female in her lifetime per generation

= Σlxmx
lx= proportion living to day
mx= average number of offspring in time interval or average daughters per mother (overlapping generations)
x= time
