Q

The regular fluctuations in animal population size is called what?

A

Population cycles

2
Q

How do you calculate the per capita birth (or death) rate?

A

=# of births (or deaths) over a time period/population

3
Q

How do you calculate the per capita increase?

A

=Per capita birth rate - Per capita death rate

4
Q

How do you calculate the Population Growth Rate

A

=r*N

–where r=per capita rate of increase, and N=size of population

5
Q

Yes/No: Can the carrying capacity be specific for a given species or a given population?

A

NO, because carrying capacity varies in time and space. It cannot be specific because it is always changing

6
Q

What does density independent mean in relation to population growth?

A

Theoretical populations do not compete and are allowed to independently grow exponentially

7
Q

What are the geometrical and arithmetical increases Thomas Malthus spoke of?

A

Population increase exponentially (geometrically), while resources increase linearly (arithmetically)
