1. Take your score & divide it by 43 ÷ 4 = 0.75
2. Take your answer & multiply it by 100
0.75 x 100 = 75

unit 7: ecology
ObjectivesWe are learning to…
explain how birth, death, immigration, and emigration influence population size
We will be successful when we can…explain how populations grow using both exponential and logistic growth patterns
Agenda
• Passport 5• Quick Check! 5• Limiting Factors

Quick Check!Which population is
decreasing in size between year 0 and 16?
Which population is increasing in size between year 13 and 16?
Which population does not change significantly between year 0 and 16?
In which population was birth rate greater than death rate from year 8 to 12?
In which population was immigration less common than emigration from year 4 to 8?
Exit TicketYou may use your assignments!

Limiting Factor = something that prevents a population from growing
exponentially
What is preventing the human population from growing infinitely big?
Limiting Factors
Explain the difference between density independent and density dependent limiting factors:
• Density dependent factors are limiting factors only affect populations when they reach a specific density.
• Density independent factors that affect all populations regardless of their densities.
Yellow Perch
Density independent limiting factors
• depth of Lake Winnipeg (affects amount of sunlight in water, and space available in lake)
• temperature of water (affects which fish will live in the lake)• turbidity of water (affects which fish will live in the lake)• migration of yellow perch (depends on which fish are strong
enough to travel)• eyes (helps yellow perch to hide from predators and hunt for
prey)• drought (natural disasters affect water temperature, levels and
turbidity)
Yellow Perch
Density dependent limiting factors
• stunting (due to lack of food or over-abundant population of yellow perch, they will stunt their growth instead of dying)
• predation (yellow perch are eaten by northern pike and walleye)
• parasitism (chestnut lampreys attach to yellow perch and feed of body fluids)
• competition (rainbow smelt compete for space and food)• crowding (rainbow smelt crowd yellow perch)
Yellow Perch
DD or DI?
a. Rainbow smelt and yellow perch attempt to occupy the same area. The more aggressive smelt survive; the perch do not. DD - competition between species only occurs at certain densities
DD or DI?
b. A severe flood brings a lot of sediment and silt into Lake Winnipeg. The turbidity of the lake increases greatly.
DI - natural disasters affect all populations regardless of density
DD or DI?
c. A drought decreases the water level in Lake Winnipeg. The carrying capacity of the lake decreases. DI - natural disasters affect all populations regardless of density
DD or DI?
d. Due to the introduction of rainbow smelt, Lake Winnipeg becomes crowded and some fish species do not survive. DD - crowding only occurs at certain densities
DD or DI?
e. Since northern pike prey on yellow perch, an increase in the perch population causes an increase in the pike population. DD - predation only occurs at certain densities
DD or DI?
f. Many fish die due to an increase in water temperature. DI - temperature affects all population densities
DD or DI?
g. Due to over-fishing, the number of walleye in Lake Winnipeg decreases. DI - human activities affect all population densities
DD or DI?
h. A population is growing quickly when parasites cause disease to spread quickly. DD - parasitism only affects certain population densities
DD or DI?
i. Since lake sturgeon migrate long distances to spawn, many do not survive the trip. DI - behaviors of organisms affect all population densities
Identify three factors that could have caused the overall decrease in the fox population
Habitat lossIntroduced predatorDiseaseOverhuntingOthers??
Fox Populations
Explain, in detail, how each factor you identified in part A would have caused the decrease
Habitat loss – By reducing the amount of space the foxes can live in, the competition between the foxes increasesIntroduced predator – A new predator could have been introduced by humans to the area and it could prey on the foxesDisease – A disease could be introduced to the fox population which is not immune to the diseaseOverhunting – Humans could overhunt the population causing rapid decreaseOthers??
