What is population?
A particular section, group, or type of people or animals living in an area or country.
What is a particular section, group, or type of people or animals living in an area or country?
Population
What is population density?
Population density is a measurement of population per unit land area.
What is a measurement of population per unit land area?
Population density
What is population distribution?
A measure of how spread out a population is in any given area.
What is a measure of how spread out a population is in any given area?
Population distribution
What is clumped distribution?
The population is distributed in clusters.
What is the population distributed in clusters?
Clumped distribution
What is uniform distribution?
Individuals are equally spaced apart.
What is it when individuals are equally spaced apart?
Uniform distribution
What is random distribution?
Individuals are spaced at unpredictable distances from each other.
What are individuals are spaced at unpredictable distances from each other?
Random distribution
What is species distribution?
The manner in which a biological taxon is spatially arranged.
What is the manner in which a biological taxon is spatially arranged?
Species distribution
How to calculate population density?
Population Density = Number of People/Land Area
How do you set up and calculate population size using quadrats?
Population = mean number of individuals per quadrat x (area of habitat / area of quadrat)
How do you set up and calculate population size using mark and recapture?
Substitute values of M (total marked), R (number of marked recaptured), and T (total recaptured on second visit) into the formula N = M T R N=\frac{MT}{R} N=RMT
How do you predict the population density and distribution of a specific species?
Population Density = Number of People/Land Area
