A population consists of the individuals of a species within a given area.
The age distribution of individuals in a population and the way those individuals are
spread over the environment describe its population structure
Population density is the number of individuals of a population per unit of area
Demographic events are events that change the structure of the population such as
death, birth, migration and emigration
Molecular markers are used such as hydrogen isotopes to determine where birds
molt during their migrations
Counting ever individual in a population is sometimes impossible so statistical
methods are used to estimate population size from samples
N1 is the number of marked individuals in the first sample
N2 is the number of individuals in the second sample
M2 is the number of marked individuals in the second sample
N is the estimated size of the population
The formula is : N1 X N2 = M2 X N
N1= N0+B D + I E
N1= the number of individuals at time 1
N0 = the number of individuals at time 0
B = the number of individuals born between time 0 and time 1
D = the number of individuals that died between time 0 and time 1
I = the number of individuals that immigrated between time 0 and time 1
E= the number of individuals that emigrated between time 0 and time 1
A life table is a useful way to display information about birth and death rates in a
population
Cohort is a group of individuals born at the same time
Survivorship is the number that are still alive at later dates

OneClass has been such a huge help in my studies at UofT especially since I am a transfer student. OneClass is the study buddy I never had before and definitely gives me the extra push to get from a B to an A!
