Population growth
Population level
In population genetics/ecology, _________ is the number of individuals/organisms in a population. It is usually denoted as N
Population growth
Population size
Select all factors governing population size
Crude birth rate (CBR)
Crude death rate (CDR)
Reproduction
Immigration
Emmigration
The birthrate; ratio of total live births in an area
Mortality
Natality
Fatality
Death rate; total ratio of deaths to the total population
Mortality
Natality
Fatality
Number of organisms moving into an area occupied by population
Emmigration
Immigration
Migration
Number of organisms moving out of an area occupied by population
Emmigration
Immigration
Migration
Measurement of number of people in an area; usually known as number of people per square km
Population count
Population density
Population
Allows for comparison among different population in terms of space and time measure
Prediction
Computation
Estimation
Select methods that can measure density
Sampling
Total mass method
Total count
Random sampling and shuffling method
Formula for sampling method
Total population = AC2 = AB2 + BC2
Total population = average number per quadrat x total area/area or quadrat
Total population = population size x natality rate
Used for very mobile or elusive species
Math Recapture Method
Mass Recapture Method
Mark Recapture Method
Pattern of spacing among individuals within geographic boundaries; it has 3 types which are clumped, random, uniform
Population dispensing
Population dispersion
Population distance
Most frequent pattern; it is when individuals are aggregated in patches
Random
Clumped
Uniform
Evenly spaced distribution, in which members of population maintain a minimum distance from each other
Random
Clumped
Uniform
Spacing pattern based on total unpredictability
Uniform
Clumped
Random
Study of vital statistics of population and how they change overtime
Topography
Lomography
Demography
Ratio of males to females in a population, classified into primary, secondary, tertiary
Gender orientation
Sexual Identity
Sex Ratio
Describes the number of individuals in each age class as a ratio of one class to another
Age structure
Age limit
Age
Age structure diagram; graphical distribution that shows distribution of various age groups and sex ratio in a population
Population Triangle
Population Pyramid
Population Hierarchy
Prereproductive ages

Table that shows the probability that a person of that age will die before his/her next birthday
Death table
Life table
Mortality table
Graph showing number of individuals surviving at each age in a given group; can be type I, type II, or type III
Survival curve
Survivorship curve
Survivor curve
Characterized by high survival in early or middle life
Type I
Type II
Type III
Greatest mortality is experienced early on in life
Type I
Type II
Type III
Roughly constant mortality rate is experienced regardless of age
Type I
Type II
Type III
Refers to how population in an area increases
