what is the purpose of random sampling?
to estimate the size of a population in an area
what is a quadrat?
a frame with a known area
to estimate population size you must
use 10 or more quadrats and place them randomly
count organisms in each quadrat
use mean number of organisms and multiply by area of field
repeat in different areas
what is systematic samplings purpose?
to see how populations and communities change over a distance
distribution using transects (systematic )?
place tape measure across area
place quadrats next to tape at regular intervals
count number of organisms in each quadrats
