The document summarizes the upcoming lab activities for the week which includes a species interaction lab on Saturday July 18th and assignments due that day. A population ecology worksheet is due on Monday. The document provides links and instructions for editing a Wikipedia page as part of the lab assignment, as well as links on how to upload images and other editing tips. Background information on human and other population growth models are also presented.

8. Logistic Growth Curve
K−N
G = rmaxN Equilibrium
K
G = growth rate Exponential
rmax= intrinsic rate
of increase Lag
N = population size
K = carrying capacity
23. Sixth extinction
Golden Toad was last
seen on May 15, 1989.
Human action has transformed between one-third and one-half of the entire land
surface of the earth.
We have lost more than one-quarter of the planet's birds, and two-thirds of the Bali tiger - 1937
major marine fisheries are fully exploited, over-exploited or depleted.
E.O. Wilson estimated that the planet is losing 30,000 species per year
-- 100 to 1000 times the background rate of species extinctions
24. What is the carrying capacity of Earth?
What do you think life on earth (including humans)
on earth will look like
• in 50 years?
• In 500 years?
• In 5000 years?
• In 50,000 years?
25. Demography - age-specific
population parameters
A. Population Size
B. Fertility
C. Mortality
D. Age structure
33. • Settled 700-800 AD
• Overpopulation in 800-1600ad
• 1722 – 1st Europeans
• 1860’s slave raids, smallpox
introduced,
• Tuberculosis, wars
• 1774 Captn Cook – statues toppling
– All down by 1830’s
34. Human Population Clock

–
How many people were added to the world
population during THIS lecture?
35. Computer simulations -
Biology Labs Online
To study aspects of human population
demography and population ecology of
sparrows.
There are two parts to the worksheet (pg 123-128)
Population Demography
Population Ecology
36. Due Saturday July 18th
Wiki project - turn in list of participants in the group, and any
additional information about how the page was edited that is not
evident from reviewing the article (before & after) and reading the
discussion page. You will receive a grade as a group.
