Unit 5 - Biology Notes
, Population Ecology
Definitions:
A population is a group of individuals of the same
species living in the same geographical area.
A community consists of all the organisms in all
the interacting populations in a given area.
An ecosystem consists of a community of
organisms together with the abiotic factors that
surround an affect it.
1
, Characteristics of Populations:
The crude population density is determined by dividing the
number of individuals by the area occupied by the organisms.
I.e. Algonquin Park has an area of 800 hectares. Find the
population density of moose, if the population size of moose
is estimated to be 500.

The ecological density is determined by dividing the number
of individuals by the area the individuals actually use.
subtracting the areas of the land where
2
species won't live in
