u5 population dynamics Flashcards
1
Q
population
A
group of organisms of the same species living within a particular area/volume
2
Q
clumped dispersion (most common pattern)
A
only some areas of habitat are favourable to survival. these areas are concentrated with live organisms
eg. prairie dogs
3
Q
uniform dispersion
A
individuals are equally spaced throughout a habitat
eg. bird nesting/orchards
4
Q
random dispersion
A
organisms are spread throughout in an unpredictable manner
eg. trees of the same species/dandelions
5
Q
quadrat sampling
A
efficient way of estimating size of small population or stationary species
NOT DANGEROUS OR MIGRATING ANIMALS
6
