second set of slides for population ecology 3/22

Question 1

change in population will give us

Answer 1

our per capita rate of increase

Question 2

change in population formula

Answer 2

change in population = births/immigrants – deaths/emmegrants

Question 3

the Exponential model is the

Answer 3

(ideal conditions)

Question 4

Exponential model formula

Answer 4

ΔN /Δt= rN

Question 5

N in exponential model =

Answer 5

of individuals

Question 6

r in exponential model =

Answer 6

rate

Question 7

t in exponential model =

Answer 7

time

Question 8

Δ/d in exponential model =

Answer 8

rate of change

Question 9

rate =

Answer 9

max. rate of growth

Question 10

why do we need ideal conditions when finding out pop.growth

Answer 10

to help us understand the capacity of species to increase and the conditions that may facilitate this growth

Question 11

rate is also the number of

Answer 11

additions and subtractions in the population true death and emmegration

Question 12

m in formulas means

Answer 12

mortality

Question 13

Exponential growth rate

Answer 13

Characteristic of populations without
limiting factors (ideal) (growing quickly

Question 14

exponential growth rate happens when species are

Answer 14

introduced to a new environment or rebounding from a catastrophe

Question 15

exponential growth rate is always rising on graphs

Answer 15

it has no limits of anything for population growth to happen,this happens mainly when animals are rebounding or introduced to a new environment

Question 16

logistic rate of growth is more

Answer 16

realistic

Question 17

logistic rate of growth

Answer 17

due to the carrying capacity and the limited amount of resources, logistic models describe how a pop.grows more slowly as it nears its carrying capacity

Question 18

K=carrying capacity

Answer 18

pop. maximizes a particular area can sustain

Question 19

s shaped curve

Answer 19

is logistic rate of growth

Question 20

j shaped curve

Answer 20

exponential growth

Question 21

logistic model is useful

Answer 21

Useful for estimating possible growth

Question 22

logistic models estimate the

Answer 22

Estimate the critical size below which populations may become extinct

Question 23

Carrying capacity

Answer 23

Maximum population size that environment can support with no degradation of habitat
varies with changes in resources

Question 24

carrying capacity is caused by

Answer 24

limited resources

Question 25

carrying capacity needs to be estimated because

Answer 25

it is difficult to design exact carrying capacity
